<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Overview of the Company&#8217;s Business. </i></b></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Sterling Construction Company, Inc. was
founded in 1991 as a Delaware corporation. Our principal executive offices are located at 1800 Hughes Landing Boulevard, Suite
250, The Woodlands, Texas 77380, and our telephone number at this address is (281) 214-0800. Our construction business was founded
in 1955 by a predecessor company in Michigan and is now conducted through our subsidiaries which primarily include: Texas Sterling
Construction Co., a Delaware corporation, or &#8220;TSC&#8221;; Road and Highway Builders, LLC, a Nevada limited liability company,
or &#8220;RHB&#8221;; Road and Highway Builders of California, Inc., a California corporation, or &#8220;RHBCa&#8221;; Ralph L.
Wadsworth Construction Company, LLC, a Utah limited liability company, or &#8220;RLW&#8221;; J. Banicki Construction, Inc., an
Arizona corporation, or &#8220;JBC&#8221;;&nbsp;and Myers &amp; Sons Construction, L.P., a California limited partnership, or &#8220;Myers&#8221;.
The terms &#8220;Company,&#8221; &#8220;Sterling,&#8221; and &#8220;we&#8221; refer to Sterling Construction Company, Inc. and
its subsidiaries except when it is clear that those terms mean only the parent company or a particular subsidiary.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Sterling is a leading heavy civil construction
company that specializes in the building and reconstruction of transportation and water infrastructure projects in Texas, Utah,
Nevada, Colorado, Arizona, California, Hawaii and other states in which there are construction opportunities. Its transportation
infrastructure projects include highways, roads, bridges, airfields, ports and light rail. Its water infrastructure projects include
water, wastewater and storm drainage systems.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Although we describe our business in this
Report in terms of the services we provide, our base of customers and the geographic areas in which we operate, we have concluded
that our operations consist of one reportable segment, one operating segment and one reporting unit component, which is heavy civil
construction. In making this determination, the Company considered the discrete financial information used by our Chief Operating
Decision Maker (&#8220;CODM&#8221;). Based on this approach, the Company noted that the CODM organizes, evaluates and manages the
financial information around each heavy civil construction project when making operating decisions and assessing the Company&#8217;s
overall performance. Furthermore, we considered that each heavy civil construction project has similar characteristics, includes
similar services, has similar types of customers and is subject to similar economic and regulatory environments.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Sterling has grown its service profile
and geographic reach both organically and through acquisitions. Expansions into Utah, Arizona and California were achieved with
the 2009 acquisition of RLW and the 2011 acquisitions of JBC and Myers, respectively. These acquisitions also extended Sterling&#8217;s
service profiles.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Recent Developments.</i></b></p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Financial Results for 2015, Operational Issues and
Outlook for 2016 Financial Results.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0 0 2pt">In 2015, the Company had an operating loss
of $14.4 million and net loss attributable to Sterling common stockholders of $20.4 million. Our gross margins have decreased to
4.6% in 2015 from 4.8% in 2014 and increased from (5.4)% in 2013. In 2015, particularly in the first quarter, our gross margins
were adversely impacted by downward revisions to estimated profitability on projects primarily awarded in Texas. These downward
revisions were primarily related to projects which are now substantially complete.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The majority of our revenues and backlog
is derived from fixed unit price contracts. Some of our revenues are derived from lump sum contracts. Fixed unit price contracts
require us to provide materials and services at a fixed unit price based on approved quantities irrespective of our actual per
unit costs. Lump sum contracts require that the total amount of work be performed for a single price irrespective of our actual
costs. As discussed in &#8220;Item 1A. Risk Factors,&#8221; we realize a profit on our contracts only if we accurately estimate
our costs and then successfully control actual costs and avoid cost overruns, and our revenues exceed actual costs. If our cost
estimates for a contract are inaccurate, or if we do not execute the contract within our cost estimates, then cost overruns may
cause the contract not to be as profitable as we expected or result in a loss, negatively affecting our cash flow, earnings and
financial position.</p>

<p style="margin: 5pt 0 2pt; font-size: 10pt; text-align: justify; text-indent: 0.25in">While the risks of cost overruns and changes
in estimated contract revenues are an inherent part of the construction business, we continue to implement the following to improve
the profitability of our projects, reduce the variability in profitability of our projects in the future and strengthen our internal
control environment:</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In addition to the factors discussed above
which impact the profitability on individual projects, there are other factors which have adversely affected our ability to secure
construction projects at favorable margins. Our highway and related bridge work is generally funded through federal and state
authorizations. In recent years, federal and state legislation related to infrastructure spending has been slow to pass. Funding
for federal highway projects primarily originate from the Highway Trust Fund where federal motor fuel taxes are the major source
of income into the fund. Additional income is provided from the General fund and certain other funds to maintain the solvency
of the fund as finding sources of income have historically been challenging. In the later part of 2015, this trend improved as
we saw the passage of federal, and several state, infrastructure funding plans. <font style="font-size: 10pt">Refer to the section
below entitled, &#8220;Our Markets and Customers,&#8221; for additional information on the federal and state funding initiatives
in our markets. Our backlog has remained essentially flat: $764 million at December 31, 2014 to $761 million at December 31, 2015,
representing sufficient work to be bid on within our markets with acceptable gross margins. Additionally, we experienced an increase
in low bid awards that are not officially awarded as contracts (&#8220;Unsigned Low-bid Awards&#8221;), which were $197 million
at the end of 2015 compared to $24 million at the end of 2014. We expect substantially all of the $197 million of Unsigned Low-bid
Awards to be signed and included in backlog in the first quarter of 2016. In addition to highway and related bridge work, we continually
look for projects that diversify our book of projects to relieve the continued pressure on our gross margins related to new contract
awards from local, state and federal authorities.</font></p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Our Markets and Customers</i></b><i>. </i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Currently, all of our operations, which
resulted in $624 million of revenues in 2015, are performed under our heavy civil construction segment and within the United States
(&#8220;U.S.&#8221;). As such, we rely heavily on federal and state infrastructure spending. Within the U.S., our principal markets
are Texas, California, Utah, Nevada, Colorado, Arizona and Hawaii. Within our principal markets, our core customers are the departments
of transportation in various states (&#8220;DOTs&#8221;), regional transit authorities, airport authorities, port authorities,
water authorities and railroads. Refer to Note 16 to the consolidated financial statements (references to &#8220;Note&#8221; or
&#8220;Notes&#8221; refer to the Notes to the consolidated financial statements for the year ended December&nbsp;31, 2015, included
in this document), for the Company&#8217;s major customers that represent a concentration of risk due to their significant revenue
contributions.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The U.S. transportation construction market
is forecasted to grow from $200.5 billion in 2015 to $208.3 billion in 2016. This increase is largely driven by the federal &#8220;Fixing
Americas Surface Transportation Act&#8221; (&#8220;Fast Act&#8221;). The Fast Act is the first law enacted in over ten years that
provides long-term funding for transportation, meaning states can move forward with critical projects with confidence as they
will now have a Federal partner over the long term. During this period, spending on highways, streets and related work is forecasted
to grow from $55.9 billion to $58.1 billion; bridges and tunnels will grow from $33.3 billion to $34.6 billion; airports and runways
are forecasted to grow from $12.9 billion to $14.3 billion; ports and waterways will remain flat at $2.3 billion; and rail/light
rail will decline slightly from $21.3 billion to $21.1 billion. In addition to the Fast Act, Texas has passed two constitutional
amendments (Proposition 1 and Proposition 7) that will increase its transportation spend by $4.0 to $4.5 billion annually. Utah
has passed a gas tax increase of five cents/gallon in 2016 with an additional one cent per gallon increase over the next four
years. This represents a 20% increase and is expected to generate $75 to $85 million in additional spending per year.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 5pt 0 2pt"><b><i>Competition.</i></b></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our competition ranges from small local
contractors to large international construction companies. We traditionally try to position ourselves to bid on work that is too
large for the small local contractors yet too small for the large international construction companies. However, if market conditions
became less favorable, we tend to see migration from both the small local contractors and large international players into our
bids. This in return reduces both revenue growth and margins.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Seasonality.</i></b></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our operations are typically affected
by weather conditions during the first and fourth quarters of our fiscal year, which may alter construction schedules and can
create variability in our revenues, profitability and the required number of employees.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Backlog is the revenue we expect to earn
in future periods on our construction projects. However, Unsigned Low-bid Awards are excluded from backlog until the contract is
executed by our customer. As the construction on our projects progresses, we increase or decrease backlog to take into account
our estimates of the effects of changes in estimated quantities, changed conditions, change orders and other variations from initially
anticipated contract revenues, including completion penalties and incentives. At December 31, 2015, our backlog was $761 million
and our Unsigned Low-bid Awards were $197 million.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Substantially all of the contracts in our
contract backlog may be canceled at the election of the customer; however, we have not been materially adversely affected by contract
cancellations or modifications in the past. See the section below entitled, &#8220;Contracts&nbsp;&#8212; Contract Management Process.&#8221;</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Construction Delivery Methods</i></b><i>.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Alternative construction delivery methods
describe different contractual and responsibility relationships among the owner, the builder and the designer of a project. There
are three primary construction delivery methods: design-bid-build, design-build and construction management.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The traditional method by which the majority
of our projects have historically been completed is design-bid-build. Under this type of construction delivery, the owner hires
a design engineer to design the project and then solicits bids from construction firms and typically awards the contract to build
the pre-designed project to the lowest qualifying bidder. The contractor to whom the project is awarded becomes the general contractor
and is responsible for completing the project in accordance with the owner&#8217;s designs using the contractor&#8217;s own employees
or resources, or subcontractors. Projects under this method are typically fixed unit price contracts.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Design-build is sometimes used by public
entities as a method of project delivery. Unlike traditional projects where the owner first hires a design firm or designs a project
itself and then puts the project out to bid for construction, design-build projects provide the owner with a single point of responsibility
and a single contact for both final design and construction. The owner selects a builder who hires the design team as required
and construction typically starts before the design is complete. This project delivery method is typically undertaken through either
fixed unit price contracts or lump sum contracts, and price is not the only determining factor used by the owner when selecting
a particular contractor.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Construction management is a newer method
of delivering a project whereby a contractor agrees to manage a project for the owner for an agreed-upon fee, which may be fixed
or may vary based upon negotiated factors. The owner of the project typically hires the contractor as a construction manager early
in the design phase of the project. The construction manager works with the design team to help ensure that the design is something
that can in fact be built within the owner&#8217;s desired cost and other parameters and that the ultimate construction contractor
will be able to understand the design drawings and specifications. There are two basic types of construction management: construction
manager as advisor and construction manager at risk. In the construction manager as advisor type of arrangement, the construction
manager acts as a technical consultant to the owner of the project and has no legal responsibility for the performance of the actual
construction work. In the construction manager at risk type of arrangement, the construction manager becomes the prime contractor
during the construction phase and makes a determination as to which portions of the work will be self-performed and which will
be performed through subcontracts. In either type of construction management process, portions of a project are often submitted
for bid during the course of the construction manager relationship, with the construction manager bidding, and oftentimes having
the first right to bid, on portions of the project.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Contracts.</i></b></p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Types of Contracts.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We provide our services primarily by using
traditional general contracting arrangements, including fixed-unit price contracts, lump sum contracts and cost-plus contracts.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Fixed unit price contracts are generally
used in competitively-bid public civil construction contracts. Contractors under fixed unit price contracts are generally committed
to provide all of the resources required to complete the contract for a fixed price per unit. These contracts are generally subject
to negotiated change orders, frequently due to differences in site conditions from those initially anticipated or asserted by the
customer. Some fixed unit price contracts provide for penalties, if the contract is not completed on time, or incentives, if it
is completed ahead of schedule.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Under a lump sum contract, the contractor
typically agrees to deliver a completed project in accordance with the contract&#8217;s requirements for a specific price, and
the customer agrees to pay the price according to a negotiated payment schedule. In developing a lump sum bid, the contractor estimates
the costs of labor, subcontracts and materials and adds an amount for overhead and profit. The amount of the profit included in
the bid is based on the contractor&#8217;s assessment of risk and other factors such as availability of resources. If the actual
costs of labor, subcontracts, materials and overhead are higher than the contractor&#8217;s estimate, the profit will be reduced
or become a loss; if the actual costs are lower, the contractor may earn more profit.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In a cost plus contract, the owner of a
project generally agrees to pay the cost of all of the contractor&#8217;s labor, subcontracts and materials plus an amount for
contractor overhead and profit (usually as a percentage of the labor, subcontracts and material cost). If actual costs are lower
than the estimate, the owner benefits from the cost savings. If actual costs are higher than the estimate, the owner bears the
economic burden of the additional costs.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Contract Management Process.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We identify potential contracts from a
variety of sources, including through subscriber services that notify us of contracts out for bid; through advertisements by federal,
state and local governmental entities; through our business development efforts; through contacts at government agencies; and through
meetings with other participants in the construction industry. After determining which contracts are available, we decide which
contracts to pursue based on such factors as the relevant skills required, the contract size and duration, the availability of
our personnel and equipment, the size and makeup of our current backlog, our competitive advantages and disadvantages, prior experience,
the contracting agency or customer, the source of contract funding, geographic location, likely competition, construction risks,
gross margin opportunities, penalties or incentives and the type of contract.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">As a condition to pursuing some contracts,
we are required to complete a prequalification process with the applicable agency or customer. Some customers, such as state departments
of transportation, require yearly prequalification, and some other customers have experience requirements specific to the contract.
The prequalification process generally limits bidders to those companies with the operational experience and financial capability
to effectively complete the particular contract in accordance with the plans, specifications and construction schedule.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">There are several factors that can create
variability in contract performance and financial results compared to our bid assumptions on a contract. The most significant of
these include the completeness and accuracy of our original bid analysis, recognition of costs associated with added scope changes,
extended overhead due to customer and weather delays, subcontractor availability and performance issues, changes in productivity
expectations, site conditions that differ from those assumed in the original bid, and changes in the availability and proximity
of materials. In addition, our original bids for some contracts are based on the contract customer&#8217;s estimates of the quantities
needed to complete a contract. If the quantities ultimately needed are different, our backlog and financial performance on the
contract will change. All of these factors can lead to inefficiencies in contract performance, which can increase costs and lower
profits. Conversely, if any of these or other factors is more favorable than the assumptions in our bid, contract profitability
can improve. Design-build projects carry additional risks such as design error risk and the risk associated with estimating quantities
and prices before the project design is completed. Design errors may result in higher than anticipated construction costs and additional
liability to the contract owner. Although we manage this additional risk by adding contingencies to our bid amounts, obtaining
errors and omissions insurance and obtaining indemnifications from our design consultants where possible, there is no guarantee
that these risk management strategies will always be successful. Generally, gross margins included in bids on design-build contracts
are higher than for other types of contracts due to the higher risks involved.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The estimating process for our traditional
fixed unit price competitive bid contracts typically involves three phases. Initially, we consider the level of anticipated competition
and our available resources for the prospective project. If we then decide to continue considering a project, we undertake the
second phase of the contract process and spend several weeks performing a detailed review of the plans and specifications, summarizing
the various types of work involved and related estimated quantities, determining the contract duration and schedule and highlighting
the unique and riskier aspects of the contract. Concurrent with this process, we estimate the cost and availability of labor, material,
equipment, subcontractors and the project team required to complete the contract on time and in accordance with the plans and specifications.
Substantially all of our estimates are made on a per-unit basis for each line item, and it is not unusual for an estimate to contain
over 300 line items. The final phase consists of a detailed review of the estimate by management, including, among other things,
assumptions regarding cost, approach, means and methods, productivity, risk and the estimated profit margin. This profit amount
will vary according to management&#8217;s perception of the degree of difficulty of the contract, the current competitive climate
and the size, availability of resources and makeup of our backlog. Our project managers are intimately involved throughout the
estimating and construction process so that contract issues, and risks, can be understood and addressed generally on a timely basis.</p>

    <!-- Field: /Page -->

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Although the factors described above are
relevant in determining the appropriate amount to bid, the contracting process is managed differently if the project is to be performed
on a design-build basis or a CM/GC basis. For design-build projects, we assemble a team that may include project managers, engineers,
quality managers and surveyors, to learn about a project that we have identified as one on which we may desire to bid. For some
projects, pre-qualification for the project is required where each contractor and/or contracting team prepares a description of
financial strengths, past experience on similar types of projects, safety record and the persons who will be on the project management
and design team, after which, the customer will usually announce a short list of three to five contractors to respond to a request
for proposal, generally within three months. Utilizing the limited design specifications provided by the customer, we generally
meet weekly over a two to three month period with design engineers to generate a bid containing quantities, prices, timing and
a description of our approach for completing the project. The customer then reviews the bids and selects the one that has the best
value, and considers factors such as contractor qualifications, the time estimated to complete the project and the price bid.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">For our CM/GC projects, the customer typically
sends out a request for proposal to general contractors for a project. The customer scores each contractor that submits a bid based
on the unit prices submitted for five to twenty items that comprise approximately 10% to 20% of the project design, the profit
margin proposed, the experience of the contractor for similar types of projects, the contractor&#8217;s approach to completing
the specific project and whether the contractor understands the CM/GC process. A committee reviews each bid and determines the
best value winner to be the general contractor. If we are the winning general contractor, we work with the customer and the engineer
to design the project. As various phases of the project are designed, we usually submit bids to construct phases of the project
for which we are qualified. In some situations, we also solicit bids from other construction contractors. If we are the lower bidder,
we are awarded a contract for that phase. In other situations, if our bid is close to the cost estimates determined by the customer
and the engineer, then we will generally be awarded the contract for a particular phase; otherwise, the customer negotiates with
us on an appropriate contract price; and if those negotiations are not successful, then the customer can terminate our contract.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">To manage risks of changes in material
prices and subcontracting costs used in tendering bids for construction contracts, we generally obtain firm price quotations from
our suppliers and subcontractors, except for fuel and trucking, before submitting a bid. For fixed unit price contracts, these
quotations do not include any quantity guarantees, and we have no obligation for materials or subcontract services beyond those
required to complete the respective contracts that we are awarded for which quotations have been provided. For design-build and
CM/GC projects, lump sum subcontracts are often executed with subcontractors.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the construction phase of a contract,
we monitor our progress by comparing actual costs incurred and quantities completed to date with budgeted amounts and the contract
schedule, and periodically prepare an updated estimate of total forecasted revenue, cost and expected profit for the contract.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the normal course of most contracts,
the customer, and sometimes the contractor, initiates modifications or changes to the original contract to reflect, among other
things, changes in quantities, specifications or design, method or manner of performance, facilities, materials, site conditions
and the period for completion of the work. In many cases, final contract quantities may differ from those specified by the customer.
Generally, the scope and price of these modifications are documented in a &#8220;change order&#8221; to the original contract and
reviewed, approved and paid in accordance with the normal change order provisions of the contract. We are often required to perform
extra or change order work under our fixed unit price contracts as directed by the customer even if the customer has not agreed
in advance on the scope or price of the work to be performed. This process may result in disputes over whether the work performed
is beyond the scope of the work included in the original contract plans and specifications or, even if the customer agrees that
the work performed qualifies as extra work, the price that the customer is willing to pay for the extra work. These disputes may
not be settled to our satisfaction. Even when the customer agrees to pay for the extra work, we may be required to fund the cost
of the work for a lengthy period of time until the change order is approved and funded by the customer. In addition, any delay
caused by the extra work may adversely impact the timely scheduling of other work on the contract (or on other contracts) and our
ability to meet contract milestone dates.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The process for resolving contract claims
varies from one contract to another but, in general, we attempt to resolve claims at the project supervisory level through the
normal change order process or, if necessary, with higher levels of management within our organization and the customer&#8217;s
organization. Regardless of the process, when a potential claim arises on a contract, we typically have the contractual obligation
to perform the work and must incur the related costs. We do not recoup the costs unless and until the claim is resolved, which
could take a significant amount of time.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Most of our construction contracts provide
for termination of the contract for the convenience of the customer, with provisions to pay us only for work performed through
the date of termination. Our backlog and results of operations have not been materially adversely affected by these provisions
in the past.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We act as the prime contractor on the majority
of the construction contracts that we undertake. We generally complete the majority of the work on our contracts with our own resources,
and we typically subcontract only specialized activities, such as traffic control, electrical systems, signage, trucking and earthmoving.
As the prime contractor, we are responsible for the performance of the entire contract, including subcontract work. Thus, we are
subject to increased costs associated with the failure of one or more subcontractors to perform as anticipated. We manage this
risk by reviewing the size of the subcontract, the financial stability of and prior experience with the subcontractor and other
factors. Although we generally do not require that our subcontractors furnish a bond or other type of security to guarantee their
performance, we require performance and payment bonds on some specialized or large subcontract portions of our contracts. Disadvantaged
business enterprise regulations require us to use our best efforts to subcontract a specified portion of contract work performed
for governmental entities to certain types of subcontractors, including minority- and women-owned businesses.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We participate in joint ventures with other
large construction companies and other partners, typically for large, technically complex projects, including design-build projects,
when it is desirable to share risk and resources in order to seek a competitive advantage or when the project is too large for
us to obtain sufficient bonding. Joint venture partners typically provide independently prepared estimates, furnish employees and
equipment, enhance bonding capacity and often also bring local knowledge and expertise. We select our joint venture partners based
on our analysis of their construction and financial capabilities, expertise in the type of work to be performed and past working
relationships with us, among other criteria.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Under a joint venture agreement, one partner
is typically designated as the sponsor or manager. The sponsoring partner typically provides all administrative, accounting and
most of the project management support for the project and generally receives a fee from the joint venture for these services.
We have been designated as the sponsoring partner in certain of our current joint venture projects and are a non-sponsoring partner
in others.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Joint venture contracts with project owners
typically impose joint and several liability on the joint venture partners. Although our agreements with our joint venture partners
provide that each party will assume and pay its share of any losses resulting from a project, if one of our partners is unable
to pay its share, we would be fully liable under our contract with the project owner. Circumstances that could lead to a loss under
these guarantee arrangements include a partner&#8217;s inability to contribute additional funds to the venture in the event that
the project incurs a loss or additional costs that we could incur should the partner fail to provide the services and resources
toward project completion that had been committed to in the joint venture agreement.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">All of our buildings and equipment are
covered by insurance, at levels which our management believes to be adequate. In addition, we maintain general liability and excess
liability insurance, workers&#8217; compensation insurance and auto insurance all in amounts consistent with our risk of loss and
industry practice.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">As a normal part of the construction business,
we are generally required to provide various types of surety and payment bonds that provide an additional measure of security for
our performance under the contract. Typically, a bidder for a contract must post a bid bond, generally for 5% to 10% of the amount
bid, and on winning the bid, must post a performance and payment bond for 100% of the contract amount. Usually, upon posting of
the performance bond, a contractor must also post a maintenance bond for generally 1% of the contract amount for one to two years.
Our ability to obtain surety bonds depends upon our capitalization, working capital, aggregate contract size, past performance,
management expertise and external factors, including the capacity of the overall surety market. Surety companies consider such
factors in light of the amount of our backlog that we have currently bonded and their current underwriting standards, which may
change from time to time. As is customary, we have agreed to indemnify our bonding company for all losses incurred by it in connection
with bonds that are issued, and we have granted our bonding company a security interest in certain assets, including accounts receivable,
as collateral for such obligation.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Government and Environmental Regulations.</i></b></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our operations are subject to compliance
with numerous regulatory requirements of federal, state and local agencies and authorities, including regulations concerning safety,
wage and hour, and other labor issues, immigration controls, vehicle and equipment operations and other aspects of our business.
For example, our construction operations are subject to the requirements of the Occupational Safety and Health Act (&#8220;OSHA&#8221;)
and comparable state laws directed toward the protection of employees. In addition, most of our construction contracts are entered
into with public authorities, and these contracts frequently impose additional governmental requirements, including requirements
regarding labor relations and subcontracting with designated classes of disadvantaged businesses.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">All of our operations are also subject
to federal, state and local laws and regulations relating to the environment, including those relating to discharges into air,
water and land, climate change, the handling and disposal of solid and hazardous waste, the handling of underground storage tanks
and the cleanup of properties affected by hazardous substances. For example, we must apply water or chemicals to reduce dust on
road construction projects and to contain contaminants in storm run-off water at construction sites. In certain circumstances,
we may also be required to hire subcontractors to dispose of hazardous wastes encountered on a project in accordance with a plan
approved in advance by the customer. Certain environmental laws impose substantial penalties for non-compliance and others, such
as the federal Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, impose strict and retroactive joint
and several liability upon persons responsible for releases of hazardous substances.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">CERCLA and comparable state laws impose
liability, without regard to fault or the legality of the original conduct, on certain classes of persons that contributed to the
release of a &#8220;hazardous substance&#8221; into the environment. These persons include the owner or operator of the site where
the release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at the site. Under
CERCLA, these persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that
have been released into the environment, for damages to natural resources and for the costs of certain health studies. CERCLA also
authorizes the federal Environmental Protection Agency, or EPA, and, in some instances, third parties, to act in response to threats
to the public health or the environment and to seek to recover from the responsible classes of persons the costs they incur.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Solid wastes, which may include hazardous
wastes, are subject to the requirements of the Federal Solid Waste Disposal Act, the Federal Resource Conservation and Recovery
Act, referred to as RCRA, and comparable state statutes. Although we do not generate solid waste, we occasionally dispose of solid
waste on behalf of customers. From time to time, the EPA considers the adoption of stricter disposal standards for non-hazardous
wastes. Moreover, it is possible that additional wastes will in the future be designated as &#8220;hazardous wastes.&#8221; Hazardous
wastes are subject to more rigorous and costly disposal requirements than are non-hazardous wastes.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We continually evaluate whether we must
take additional steps at our locations to ensure compliance with environmental laws. While compliance with applicable regulatory
requirements has not materially adversely affected our operations in the past, there can be no assurance that these requirements
will not change and that compliance will not adversely affect our operations in the future. In addition, tighter regulation for
the protection of the environment and other factors may make it more difficult to obtain new permits and renewal of existing permits
may be subject to more restrictive conditions than currently exist.</p>

available supply of management, supervisory and field personnel. Substantially all of our employees are hired on a full-time basis;
however, as is typical in the construction industry, we experience a high degree of turnover as a result of construction projects
being completed. In the past, we have been able to attract sufficient numbers of personnel to support the growth of our operations.
However, we continue to face intense competition for experienced workers in all our markets.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The risks described below are those we
believe to be the material risks we face. Any of the risk factors described below could significantly and adversely affect our
business, prospects, financial condition, results of operations and cash flows.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Risks Relating to Our Business</i></b><i>. </i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>If we are unable to accurately
estimate the overall risks, requirements or costs when we bid on or negotiate a contract that is ultimately awarded to us, we may
achieve a lower than anticipated profit or incur a loss on the contract.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The majority of our revenues and backlog
are derived from fixed unit price contracts. Some of our revenues are derived from lump sum contracts. Fixed unit price contracts
require us to provide materials and services at a fixed unit price based on approved quantities irrespective of our actual per
unit costs. Lump sum contracts require that the total amount of work be performed for a single price irrespective of our actual
per unit costs. We realize a profit on our contracts only if we accurately estimate our costs and then successfully control actual
costs and avoid cost overruns, and our revenues exceed actual costs. If our cost estimates for a contract are inaccurate, or if
we do not execute the contract within our cost estimates, then cost overruns may cause us to incur losses or cause the contract
not to be as profitable as we expected. The final results under these types of contracts could negatively affect our cash flow,
earnings and financial position.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The costs incurred and gross profit realized
on our contracts can vary, sometimes substantially, from our original projections due to a variety of factors, including, but not

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Many of our contracts with public sector
customers contain provisions that purport to shift some or all of the above risks from the customer to us, even in cases where
the customer is partly at fault. Our experience has often been that public sector customers have been willing to negotiate equitable
adjustments in the contract compensation or completion time provisions if unexpected circumstances arise. However, public sector
customers may seek to impose contractual risk-shifting provisions more aggressively, which could increase risks and adversely affect
our cash flow, earnings and financial position.</p>

our profitability.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our revenue has fluctuated in recent years,
in part through market conditions and, in 2007, 2009 and 2011, acquisitions that expanded our geographical footprint. We may be
unable to grow our revenues for a variety of reasons, including decreased government funding for infrastructure projects, limits
on additional growth in our current markets, reduced spending by our customers, an increased number of competitors, less success
in competitive bidding for contracts, limitations on access to necessary working capital and investment capital to sustain growth,
limitations on access to bonding to support increased contracts and operations, inability to hire and retain essential personnel
and to acquire equipment to support growth, and inability to identify acquisition candidates and successfully acquire and integrate
them into our business. A substantial decline in our revenue could have a material adverse effect on our financial condition and
results of operations if we are unable to also reduce our operating expenses. See &#8220;Recent Developments &#8213; Financial

of infrastructure projects could reduce our revenues and profits and have a material adverse effect on our results of operations.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our business is highly dependent on the
amount and timing of infrastructure work funded by various governmental entities, which, in turn, depends on the overall condition
of the economy, the need for new or replacement infrastructure, the priorities placed on various projects funded by governmental
entities and federal, state or local government spending levels. Spending on infrastructure could decline for numerous reasons,
including decreased revenues received by state and local governments for spending on such projects, including federal funding.
The most recent recession caused a nationwide decline in home sales and an increase in foreclosures, which correspondingly resulted
in decreases in property taxes and some other local taxes, which are among the sources of funding for municipal road, bridge and
water infrastructure construction. State spending on highway and other projects can be adversely affected by decreases or delays
in, or uncertainties regarding, federal highway funding, which could adversely affect us. We are reliant upon contracts with state
transportation departments for a significant portion of our revenues.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">See &#8220;Business&#8722;Our Markets and
Customers&#8221; above for a more detailed discussion of our markets and their funding sources.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>We operate in Texas, Utah, Nevada, Colorado, Arizona,
California, Hawaii and to a lesser extent in other states, and adverse changes to the economy and business environment in those
states have had an adverse effect on, and could continue to adversely affect, our operations, which could lead to lower revenues
and reduced profitability.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Because of this concentration in specific
geographic locations, we are susceptible to fluctuations in our business caused by adverse economic or other conditions in these
regions, including natural or other disasters. The stagnant or depressed economy, to varying degrees, in Texas, Utah, Nevada, Colorado,
Arizona, California and Hawaii have adversely affected, and could continue to adversely effect, our business and results of operations.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>The cancellation of significant contracts or our
disqualification from bidding for new contracts could reduce our revenues and profits and have a material adverse effect on our
results of operations.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Contracts that we enter into with governmental
entities can usually be canceled at any time by them with payment only for the work already completed. In addition, we could be
prohibited from bidding on certain governmental contracts if we fail to maintain qualifications required by those entities. A cancellation
of an unfinished contract or our debarment from the bidding process could cause our equipment and work crews to be idled for a
significant period of time until other comparable work becomes available, which could have a material adverse effect on our business
and results of operations.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Our industry is highly competitive, with a variety
of companies competing against us, and our failure to compete effectively could reduce the number of new contracts awarded to us
or adversely affect our margins on contracts awarded.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In the past, a majority of the contracts
on which we bid were awarded through a competitive bid process, with awards generally being made to the lowest bidder, but sometimes
recognizing other factors, such as shorter contract schedules or prior experience with the customer. For our design-build, CM/GC
and other alternative methods of delivering projects, reputation, marketing efforts, quality of design and minimizing public inconvenience
are also significant factors considered in awarding contracts, in addition to cost. Within our markets, we compete with many international,
national, regional and local construction firms. Some of these competitors have achieved greater market penetration than we have
in the markets in which we compete, and some may have greater financial and other resources than we do. In addition, there are
a number of international and national companies in our industry that are larger than we are and that, if they so desire, could
establish a presence in our markets and compete with us for contracts.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In some markets where residential and commercial
projects have significantly diminished, the bidding environment in our markets has been much more competitive as construction companies
that lack available work in those markets have begun bidding on projects in our markets, sometimes at bid levels below our break-even
pricing. In addition, traditional competitors on larger transportation and water infrastructure projects also appear to have been
bidding at less than normal margins, and in some cases at below our break-even pricing, in order to replenish their backlogs. As
a result, we may need to accept lower contract margins in order to compete against competitors that have the ability to accept
awards at lower prices or have a pre-existing relationship with a customer.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In addition, if the use of design-build,
CM/GC and other alternative project delivery methods continues to increase and we are not able to further develop our capabilities
and reputation in connection with these alternative delivery methods, we will be at a competitive disadvantage, which may have
a material adverse effect on our financial position, results of operations, cash flows and prospects. If we are unable to compete
successfully in our markets, our relative market share and profits could also be reduced.</p>

materials (including petroleum-based products) could increase our costs and impair our ability to complete contracts on a timely
basis or at all, which would adversely affect our profits and cash flow.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We rely on third-party subcontractors to
perform some of the work on many of our contracts. We generally do not bid on contracts unless we have the necessary subcontractors
committed for the anticipated scope of the contract and at prices that we have included in our bid, except in some instances for
trucking arrangements. Therefore, to the extent that we cannot engage subcontractors, our ability to bid for contracts may be impaired.
In addition, if a subcontractor is unable to deliver its services according to the negotiated terms for any reason, including the
deterioration of its financial condition, we may suffer delays and be required to purchase the services from another source at
a higher price or incur other unanticipated costs. This may reduce the profit to be realized, or result in a loss, on a contract.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We also rely on third-party suppliers to
provide most of the materials (including aggregates, cement, asphalt, concrete, steel, pipe, oil and fuel) for our contracts, except
in Utah and Nevada where we source and produce some of the aggregates we use from quarries in which we have mining rights. We do
not own or operate any quarries in Texas, Arizona, California, or Hawaii. We normally do not bid on contracts unless we have commitments
from suppliers for the materials and subcontractors for certain of the services required to complete the contract and at prices
that we have included in our bid, except for some construction projects in Utah and Nevada where we use aggregates from quarries
in which we have mining rights. Thus, to the extent that we cannot obtain commitments from our suppliers for materials and subcontractors
for certain of the services, our ability to bid for contracts may be impaired. In addition, if a supplier or subcontractor is unable
to deliver materials or services according to the negotiated terms of a supply/services agreement for any reason, including the
deterioration of its financial condition, we may suffer delays and be required to purchase the materials/services from another
source at a higher price or incur other unanticipated costs. This may reduce the profit to be realized, or result in a loss, on
a contract.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Diesel fuel and other petroleum-based products
are utilized to operate the plants and equipment on which we rely to perform our construction contracts. In addition, our asphalt
plants and suppliers use oil in combination with aggregates to produce asphalt used in our road and highway construction projects.
Decreased supplies of such products relative to demand, unavailability of petroleum supplies due to refinery turnarounds, higher
prices charged for petroleum based products and other factors can increase the cost of such products. Future increases in the costs
of fuel and other petroleum-based products used in our business, particularly if a bid has been submitted for a contract and the
costs of such products have been estimated at amounts less than the actual costs thereof, could result in a lower profit, or a
loss, on a contract.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>We may not accurately assess the quality, and we
may not accurately estimate the quantity, availability and cost, of aggregates we plan to produce, particularly for projects in
rural areas, which could have a material adverse effect on our results of operations.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Particularly for projects in rural areas,
we typically estimate the quality, quantity, availability and cost for anticipated aggregate sources that we have not previously
used to produce aggregates, which increases the risk that our estimates may be inaccurate. Inaccuracies in our estimates regarding
aggregates could result in significantly higher costs to supply aggregates needed for our projects, as well as potential delays
and other inefficiencies. As a result, our failure to accurately assess the quality, quantity, availability and cost of aggregates
could cause us to incur losses, which could materially adversely affect our results of operations.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>If we are unable to attract and retain key personnel

impacted.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our ability to attract and retain reliable,
qualified personnel is a significant factor that enables us to successfully bid for and profitably complete our work. This includes
members of our management, project managers, estimators, supervisors, foremen, equipment operators and laborers. The loss of the
services of any of our management could have a material adverse effect on us. Our future success will also depend on our ability
to hire and retain, or to attract when needed, highly-skilled personnel. If competition for these employees is intense, we could
experience difficulty hiring and retaining the personnel necessary to support our business. If we do not succeed in retaining our
current employees and attracting, developing and retaining new highly-skilled employees, our reputation may be harmed and our operations
and future earnings may be negatively impacted.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We rely heavily on immigrant labor. We
have taken steps that we believe are sufficient and appropriate to ensure compliance with immigration laws. However, we cannot
provide assurance that we have identified, or will identify in the future, all illegal immigrants who work for us. Our failure
to identify illegal immigrants who work for us may result in fines or other penalties being imposed upon us, which could have a
material adverse effect on our operations, results of operations and financial condition.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In Nevada, Arizona, California and Hawaii,
a substantial number of our equipment operators and laborers are unionized. Any work stoppage or other labor dispute involving
our unionized workforce, or inability to renew contracts with the unions, could have a material adverse effect on our operations
and operating results.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Our contracts may require us to perform extra or

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our contracts often require us to perform
extra or change order work as directed by the customer even if the customer has not agreed in advance on the scope or price of
the extra work to be performed. This process may result in disputes over whether the work performed is beyond the scope of the
work included in the original project plans and specifications or, if the customer agrees that the work performed qualifies as
extra work, the price that the customer is willing to pay for the extra work. These disputes may not be settled to our satisfaction.
Even when the customer agrees to pay for the extra work, we may be required to fund the cost of such work for a lengthy period
of time until the change order is approved by the customer and we are paid by the customer.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">To the extent that actual recoveries with
respect to change orders or amounts subject to contract disputes or claims are less than the estimates used in our financial statements,
the amount of any shortfall will reduce our future revenues and profits, and this could have a material adverse effect on our reported
working capital and results of operations. In addition, any delay caused by the extra work may adversely impact the timely scheduling
of other project work and our ability to meet specified contract milestone dates.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Our failure to meet schedule or performance requirements
of our contracts could adversely affect us.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In most cases, our contracts require completion
by a scheduled acceptance date. Failure to meet any such schedule could result in additional costs, penalties or liquidated damages
being assessed against us, and these could exceed projected profit margins on the contract. Performance problems on existing and
future contracts could cause actual results of operations to differ materially from those anticipated by us and could cause us
to suffer damage to our reputation within the industry and among our customers.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>The design-build project delivery method subjects
us to the risk of design errors and omissions.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In the event of a design error or omission
causing damages with respect to one of our design-build projects, we could be liable. Although we pass design responsibility on
to the engineering firms that we engage to perform design services on our behalf for these projects, in the event of a design error
or omission causing damages, there is risk that the engineering firm, its professional liability insurance, and the errors and
omissions insurance that they and we purchase will not fully protect us from costs or liabilities. Any liabilities resulting from
an asserted design defect with respect to our construction projects may have a material adverse effect on our financial position,
results of operations and cash flows.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Adverse weather conditions may cause delays, which
could slow completion of our contracts and negatively affect our revenues and cash flow.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Because all of our construction projects
are built outdoors, work on our contracts is subject to unpredictable weather conditions, which could become more frequent or severe
if general climatic changes occur. For example, evacuations in Texas due to hurricanes along the U.S. Gulf of Mexico coastal areas
can result in our inability to perform work on all Houston-area contracts for several days. Lengthy periods of wet or cold winter
weather will generally interrupt construction, and this can lead to under-utilization of crews and equipment, resulting in less
efficient rates of overhead recovery. Extreme heat can prevent us from performing certain types of operations. During the late
fall to the early spring months of each year, our work on construction projects in Nevada and Utah may also be curtailed because
of snow and other work-limiting weather. While revenues can be recovered following a period of bad weather, it is generally impossible
to recover the cost of inefficiencies, and significant periods of bad weather typically reduce profitability of affected contracts
both in the current period and during the future life of affected contracts. Such reductions in contract profitability negatively
affect our results of operations in current and future periods until the affected contracts are completed.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Timing of the award and performance of new contracts
could have an adverse effect on our operating results and cash flow.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">It is generally very difficult to predict
whether and when new contracts will be offered for tender, as these contracts frequently involve a lengthy and complex design and
bidding process, which is affected by a number of factors, such as market conditions, funding arrangements and governmental approvals.
Because of these factors, our results of operations and cash flows may fluctuate from quarter to quarter and year to year, and
the fluctuation may be substantial.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The uncertainty of the timing of contract
awards may also present difficulties in matching the size of our equipment fleet and work crews with contract needs. In some cases,
we may maintain and bear the cost of more equipment and ready work crews than are currently required, in anticipation of future
needs for existing contracts or expected future contracts. If a contract is delayed or an expected contract award is not received,
we would incur costs that could have a material adverse effect on our anticipated profit.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In addition, the timing of the revenues,
earnings and cash flows from our contracts can be delayed by a number of factors, including adverse weather conditions, such as
prolonged or intense periods of rain, snow, storms or flooding; delays in receiving material and equipment from suppliers and services
from subcontractors; and changes in the scope of work to be performed. Such delays, if they occur, could have adverse effects on
our operating results for current and future periods until the affected contracts are completed.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Our participation in construction joint ventures

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">As part of our business, we are a party
to joint venture arrangements, pursuant to which we typically jointly bid on and execute particular projects with other companies
in the construction industry. Success on these joint projects depends upon managing the risks discussed in the various risks described
in these &#8220;Risk Factors&#8221; and on whether our joint venture partners satisfy their contractual obligations.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We and our joint venture partners are generally
jointly and severally liable for all liabilities and obligations of our joint ventures. If a joint venture partner fails to perform
or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities stemming
from lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate
share of a liability to make up for our partner&#8217;s shortfall. Furthermore, if we are unable to adequately address our partner&#8217;s
performance issues, the customer may terminate the project, which could result in legal liability to us, harm to our reputation
and reduction to our profit on a project.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In connection with acquisitions, certain
counterparties to joint venture arrangements, which may include our historical direct competitors, may not desire to continue such
arrangements with us and may terminate the joint venture arrangements or not enter into new arrangements. Any termination of a
joint venture arrangement could cause us to reduce our backlog and could materially and adversely affect our business, results
of operations and financial condition.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Our dependence on a limited number of customers could
adversely affect our business and results of operations.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Due to the size and nature of our construction
contracts, one or a few customers have in the past and may in the future represent a substantial portion of our consolidated revenues
and gross profits in any one year or over a period of several consecutive years. For example, in 2015, approximately 13.5% of our
revenue was generated from Texas Department of Transportation (&#8220;TXDOT&#8221;) and approximately 15.5% was generated by the
California Department of Transportation (&#8220;Caltrans&#8221;). Similarly, our backlog frequently reflects multiple contracts
for certain customers; therefore, one customer may comprise a significant percentage of backlog at a certain point in time. Examples
of this are TXDOT, Caltrans and Nevada Department of Transportation which comprised 25.7%, 14.1% and 11.4% of our backlog at December
31, 2015, respectively. The loss of business from any one of such customers could have a material adverse effect on our business
or results of operations. Also, a default or delay in payment on a significant scale by a customer could materially adversely affect
our business, results of operations, cash flows and financial condition.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>We may incur higher costs to lease, acquire and maintain
equipment necessary for our operations, and the market value of our owned equipment may decline.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">A significant portion of our contracts
is built with our own construction equipment rather than leased or rented equipment. To the extent that we are unable to buy construction
equipment necessary for our needs, either due to a lack of available funding or equipment shortages in the marketplace, we may
be forced to rent equipment on a short-term basis, which could increase the costs of performing our contracts.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The equipment that we own or lease requires
continuous maintenance, for which we maintain our own repair facilities. If we are unable to continue to maintain the equipment
in our fleet, we may be forced to obtain third-party repair services, which could increase our costs. In addition, the market
value of our equipment may unexpectedly decline at a faster rate than anticipated.</p>

we are required to provide surety bonds to our customers to secure our performance under construction contracts. Our ability to
obtain surety bonds primarily depends upon our capitalization, working capital, past performance, management expertise and reputation
and certain external factors, including the overall capacity of the surety market. Surety companies consider such factors in relationship
to the amount of our backlog and their underwriting standards, which may change from time to time. Events that adversely affect
the insurance and bonding markets generally may result in bonding becoming more difficult to obtain in the future, or being available
only at a significantly greater cost. Our inability to obtain adequate bonding would limit the amount that we can bid on new contracts

associated with providing construction and related services on construction sites, plants and quarries. Operating hazards can cause
personal injury and loss of life, damage to or destruction of property, plant and equipment and environmental damage. We maintain
general liability and excess liability insurance, workers&#8217; compensation insurance, auto insurance and other types of insurance
all in amounts consistent with our risk of loss and industry practice, but this insurance may not be adequate to cover all losses
or liabilities that we may incur in our operations.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Insurance liabilities are difficult to
assess and quantify due to unknown factors, including the severity of an injury, the determination of our liability in proportion
to other parties, the number of incidents not reported and the effectiveness of our safety program. If we were to experience insurance
claims or costs above our estimates, we might be required to use working capital to satisfy these claims rather than to maintain
or expand our operations. To the extent that we experience a material increase in the frequency or severity of accidents or workers&#8217;
compensation and health claims, or unfavorable developments on existing claims, our operating results and financial condition could
be materially and adversely affected.</p>

laws and regulations relating to the management, disposal and remediation of hazardous substances, climate change and the emission
and discharge of pollutants into the air and water. We could be held liable for such contamination created not only from our own
activities but also from the historical activities of others on our project sites or on properties that we acquire or lease. Our
operations are also subject to laws and regulations relating to workplace safety and worker health, which, among other things,
regulate employee exposure to hazardous substances. Immigration laws require us to take certain steps intended to confirm the legal
status of our immigrant labor force, but we may nonetheless unknowingly employ illegal immigrants. Violations of such laws and
regulations could subject us to substantial fines and penalties, cleanup costs, third-party property damage or personal injury
claims. In addition, these laws and regulations have become, and enforcement practices and compliance standards are becoming, increasingly
stringent. Moreover, we cannot predict the nature, scope or effect of legislation or regulatory requirements that could be imposed,
or how existing or future laws or regulations will be administered or interpreted, with respect to products or activities to which
they have not been previously applied. Compliance with more stringent laws or regulations, as well as more vigorous enforcement
policies of the regulatory agencies, could require us to make substantial expenditures for, among other things, pollution control
systems and other equipment that we do not currently possess, or the acquisition or modification of permits applicable to our activities.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our aggregate quarry leases in Utah and

in &#8220;Item 7. Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations&nbsp;&#8212; Critical
Accounting Policies,&#8221; we recognize contract revenue using the percentage-of-completion method. Under this method, estimated
contract revenue is recognized by applying the percentage of completion of the contract for the period (based on the ratio of costs
incurred to total estimated costs of a contract) to the total estimated revenue for the contract. Estimated contract losses are
recognized in full when determined. Contract revenue and total cost estimates are reviewed and revised on a continuous basis as
the work progresses and as change orders are initiated or approved, and adjustments based upon the percentage of completion are
reflected in contract revenue in the accounting period when these estimates are revised. To the extent that these adjustments result
in an increase, a reduction or an elimination of previously reported contract profit, we recognize a credit or a charge against
current earnings, which could be material.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our ability to obtain additional financing
in the future will depend in part upon prevailing credit and equity market conditions, as well as conditions in our business and
our operating results; such factors may adversely affect our efforts to arrange additional financing on terms satisfactory to us.
We have pledged the proceeds and other rights under our construction contracts to our bond surety, and we have pledged substantially
all of our other assets as collateral in connection with our equipment-based credit facility. As a result, we may have difficulty
in obtaining additional financing in the future if such financing requires us to pledge assets as collateral. In addition, under
our equipment-based credit facility, we must obtain the consent of our lenders to incur any amount of additional debt from other
sources (subject to certain exceptions). If future financing is obtained by the issuance of additional shares of common stock,
our stockholders may suffer dilution. If adequate funds are not available, or are not available on acceptable terms, we may not
be able to make future investments, take advantage of acquisitions or other opportunities, or respond to competitive challenges.</p>

of the Company&#8217;s 50%-owned affiliates. The sum of the amount borrowed may not exceed the lesser of $40 million or 65% of
the appraised value of the collateral pledged for the facility. At December 31, 2015, the Company had approximately $29.6 million
of borrowing base which was the result of calculating 65% of the appraised value of the Company&#8217;s collateral. Based on market
conditions, which includes the amount of construction work available and the demand for construction equipment, the appraised value
of our equipment may be subject to fluctuating values. If these market conditions are unfavorable, we may see a decline in our

on our consolidated balance sheet at December 31, 2015. Goodwill represents the excess of cost over the fair value of net assets
acquired in business combinations reduced by any impairments recorded subsequent to the date of acquisition. A shortfall in our
revenues or net income or changes in various other factors from that expected by securities analysts and investors could significantly
reduce the market price of our common stock. If our market capitalization drops significantly below the amount of net equity recorded
on our balance sheet, it might indicate a decline in our fair value and would require us to further evaluate whether our goodwill
has been impaired. We perform an annual test of our goodwill to determine if it has become impaired. On an interim basis, we also
review the factors that have or may affect our operations or market capitalization for events that may trigger impairment testing.
Write downs of goodwill may be substantial. If we were required to write down all or a significant part of our goodwill in future
periods our net earnings and equity could be materially and adversely affected.</p>

change in the Company&#8217;s cumulative total stockholder return on its common stock for the last five years with the <i>Dow Jones

marketing strategy is focused on a limited product line, such as civil construction. Both indices are published in <i>The</i> <i>Wall

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The returns are calculated assuming that
an investment with a value of $100 was made in the Company&#8217;s common stock and in each index at the end of 2010 and that all
dividends were reinvested in additional shares of common stock; however, the Company has paid no dividends during the periods shown.
The graph lines merely connect the measuring dates and do not reflect fluctuations between those dates. The stock performance shown
on the graph is not intended to be indicative of future stock performance.</p>

heavy civil construction, through our subsidiaries, and which specializes in the building and reconstruction of transportation
and water infrastructure in Texas, Utah, Nevada, Colorado, Arizona, California, Hawaii and other states in which there are profitable
construction opportunities. Its transportation infrastructure projects include highways, roads, bridges, airfields, ports and light
rail. Its water infrastructure projects include water, wastewater and storm drainage systems. We have strategically expanded our
operations, either by establishing an office in a new market, often after having successfully bid on and completed a project in
that market, or by acquiring a company that gives us an immediate entry into a market.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our significant accounting policies are
described in Note&nbsp;1 to the consolidated financial statements, and conform to the Financial Accounting Standards Board&#8217;s
Accounting Standards Codification (or GAAP or ASC).</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Use of Estimates.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The preparation of financial statements
in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities,
the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues
and expenses during the reporting period. Certain of the Company&#8217;s accounting policies require higher degrees of judgment
than others in their application. These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion
method, the valuation of long-lived assets (including goodwill), and income taxes. Management continually evaluates all of its
estimates and judgments based on available information and experience; however, actual amounts could differ from those estimates.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"><i>Revenue Recognition.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The majority of our construction contracts
with our customers are &#8220;fixed unit price.&#8221; Under such contracts, we are committed to providing materials or services
required by a contract at fixed unit prices (for example, dollars per cubic yard of concrete poured or per cubic yard of earth
excavated). Most of our state and municipal contracts provide for termination of the contract for the convenience of the owner,
with provisions to pay us only for work performed through the date of termination.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Revenue from these construction contracts
is recognized using the percentage-of-completion accounting method. Under this method, revenue is recognized as costs are incurred
in an amount equal to cost plus the related expected profit based on the ratio of costs incurred to estimated final costs. This
cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract
costs consist of direct costs on contracts, including labor, materials, amounts payable to subcontractors and those indirect costs
related to contract performance, such as indirect salaries and wages, equipment maintenance, repairs, fuel and depreciation, insurance
and payroll taxes. Contract cost is recorded as incurred, and revisions in contract revenue and cost estimates are reflected in
the accounting period when known. Provisions for estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Changes in job performance, job conditions and estimated profitability, including those changes arising
from contract change orders, penalty provisions and final contract settlements may result in revisions to costs and income and
are recognized in the period in which the revisions are determined.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Change orders are modifications of an original
contract that effectively change the existing provisions of the contract without adding new scope or terms. Change orders may include
changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of
the work. Either we or our customers may initiate change orders.</p>

    <!-- Field: /Page -->

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company considers unapproved change
orders to be contract variations for which we have customer approval for a change of scope but a price change associated with the
scope change has not yet been agreed upon. Costs associated with unapproved change orders are included in the estimated cost to
complete the contracts and are treated as project costs as incurred. The Company recognizes revenue equal to costs incurred on
unapproved change orders when realization of price approval is probable. Unapproved change orders involve the use of estimates,
and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting
periods to reflect changes in estimates or final agreements with customers. Change orders that are unapproved as to both price
and scope are evaluated as claims.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company considers claims to be amounts
in excess of agreed contract prices that we seek to collect from our customers or others for customer-caused delays, errors in
specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope
and price, or other causes of unanticipated additional contract costs. Claims are included in the calculation of revenue when realization
is probable and amounts can be reliably determined. To support these requirements, the existence of the following items must be
satisfied: 1. The contract or other evidence provides a legal basis for the claim; or a legal opinion has been obtained, stating
that under the circumstances there is a reasonable basis to support the claim; 2. Additional costs are caused by circumstances
that were unforeseen at the contract date and are not the result of deficiencies in the contractor&#8217;s performance; 3. Costs
associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and 4. The
evidence supporting the claim is objective and verifiable, not based on management&#8217;s feel for the situation or on unsupported
representations. Revenues in excess of contract costs incurred on claims are recognized when an agreement is reached with customers
as to the value of the claims, which in some instances may not occur until after completion of work under the contract. Costs associated
with claims are included in the estimated costs to complete the contracts and are treated as project costs when incurred.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our contracts generally take 12 to 36 months
to complete. The Company generally provides a one to two-year warranty for workmanship under its contracts when completed. Warranty
claims historically have been insignificant.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The accuracy of our revenue and profit
recognition in a given period is dependent on the accuracy of our estimates of the revenues and costs to finish uncompleted contracts.
Our estimates for all of our significant contracts use a highly detailed &#8220;bottom up&#8221; approach. However, our projects
can be highly complex, and in almost every case, the profit margin estimates for a contract will either increase or decrease to
some extent from the amount that was originally estimated at the time of bid. Because we have a large number of projects of varying
levels of size and complexity in process at any given time, these changes in estimates can sometimes offset each other without
materially impacting our overall profitability. However, large changes in revenue or cost estimates can have a significant effect
on profitability. There are a number of factors that can contribute to changes in estimates of contract cost and profitability.
The most significant of these include the completeness and accuracy of the original bid, recognition of costs associated with scope
changes, extended overhead due to customer-related and weather-related delays, subcontractor and supplier performance issues, site
conditions that differ from those assumed in the original bid (to the extent contract remedies are unavailable), the availability
and skill level of workers in the geographic location of the project and changes in the availability and proximity of materials.
The foregoing factors, as well as the stage of completion of contracts in process and the mix of contracts at different margins,
may cause fluctuations in gross profit between periods, and these fluctuations may be significant. Results for 2015, 2014 and 2013
were adversely affected by revisions to estimated profitability on a number of construction projects. See &#8220;Recent Developments
&#8213; Financial Results for 2015, Operational Issues and Outlook for 2016 Financial Results&#8221; above and &#8220;Results of
Operations &#8213; Fiscal Year Ended December 31, 2015 Compared with Fiscal Year Ended December 31, 2014&#8221; for further discussion
of the impact on our financial results.</p>

<p style="font-size: 10pt; text-indent: 0in; margin: 5pt 0 2pt"><i>Contracts Receivable, Including Retainage.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Contracts receivable are generally based
on amounts billed to the customer and currently due in accordance with our contracts. Many of the contracts under which the Company
performs work contain retainage provisions. Retainage refers to that portion of billings made by the Company but held for payment
by the customer pending satisfactory completion of the project. Retainage on active contracts is classified as a current asset
regardless of the term of the contract and is generally collected within one year of the completion of a contract. At December
31, 2015 and 2014, contracts receivable included $19.8 million and $16.4 million of retainage, respectively, which is being contractually
withheld by customers until completion of the contracts.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">There are certain contracts that are completed
in advance of full payment. When the receivable will not be collected within our normal operating cycle, we consider it a long-term
contract receivable and it is recorded in &#8220;Other assets, net&#8221; in our balance sheet. At December 2015 and 2014, there
was zero and $5.0 million recorded, respectively. We considered the credit quality of the borrower to assess the appropriate discount
rate to apply and continuously monitor the borrower&#8217;s credit quality.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"></p>

<!-- Field: Page; Sequence: 25; Value: 2 -->
    <div style="margin-top: 12pt; margin-bottom: 6pt; border-bottom: Black 4pt solid"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="width: 100%; text-align: center"><!-- Field: Sequence; Type: Arabic; Name: PageNo -->25<!-- Field: /Sequence --></td></tr></table></div>

    <!-- Field: /Page -->

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">As the majority of our construction contracts
are entered into with state or municipal government customers, credit risk is minimal. The Company ascertains that funds have been
appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject
to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract
price for completed work and reimbursement of termination-related costs. Credit risk with private owners is minimized because of
statutory mechanics liens, which give the Company high priority in the event of lien foreclosures following financial difficulties
of private owners.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Contracts receivable are written off based
on individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. There was minimal
bad debt expense recorded in 2015 and no bad debt expense recoded in 2014. In 2013, the Company wrote off $1.8 million of contracts
receivable to bad debt expense which was recorded in &#8220;Other operating (expense) income, net.&#8221; During 2014, we recovered
$1.0 million of this $1.8 million.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Based upon a review of outstanding contracts
receivable, historical collection information and existing economic conditions, management has determined that substantially all
of contracts receivable at December 31, 2015 are fully collectible, and accordingly, an immaterial allowance for doubtful accounts
against contracts receivable was recorded.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Valuation of Long-Lived Assets and Goodwill.</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Long-lived assets, which include property,
equipment and acquired intangible assets, including goodwill, are reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. Impairment evaluations involve fair values and management
estimates of useful asset lives and future cash flows. Actual useful lives and cash flows could be different from those estimated
by management, and this could have a material effect on operating results and financial position. For the year ended December 31,
2015, there were no events or changes in circumstances that would indicate a material impairment of our long-lived assets. For
the year ended December 31, 2014, there was no impairment of our long-lived assets.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Goodwill must be tested for impairment
at least annually, and we performed our most recent annual impairment test of historical goodwill on October 1, 2015. Based on
our one reporting unit, our test indicated there was no impairment of goodwill. See &#8220;Segment Reporting&#8221; below for further
information regarding the determination of our reporting unit. Note 8 to the consolidated financial statements discusses the two
valuation approaches used by the Company to determine the fair value of the Company&#8217;s equity for purposes of evaluating whether
there is an indication of goodwill impairment. These valuation approaches are impacted by a number of factors but the key factors
are the Company&#8217;s stock price, the estimated control premium and our estimated forecast of future cash flows. The valuation
approaches contain uncertainty regarding the estimates used. One of the largest uncertainties relates to local, state and government
spending which management expects to increase in the upcoming years. There are a number of other uncertainties with respect to
our future financial performance that could impact estimated future cash flows. These are discussed in a number of places including
&#8220;Item 1A. Risk Factors.&#8221; We determined that the fair value of the Company&#8217;s equity was approximately 21% and
13% above the carrying value of the Company&#8217;s equity at December 31, 2015 and 2014, respectively. At December 31, 2015, we
had goodwill with a remaining carrying amount of approximately $54.8 million.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Deferred tax assets and liabilities are
recognized based on the differences between the financial statement carrying amounts and the tax bases of assets and liabilities.
We regularly review our deferred tax assets for recoverability and, where necessary, establish a valuation allowance.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Valuation allowances are established to
reduce deferred tax assets if we determine that it is more likely than not (e.g., a likelihood of more than 50%) that some or all
of the deferred tax assets will not be realized in future periods. To assess the likelihood, we use estimates and judgment regarding
our future taxable income, as well as the jurisdiction in which this taxable income is generated, to determine whether a valuation
allowance is required. Such evidence can include our current financial position, our results of operations, both actual and forecasted
results, the reversal of deferred tax liabilities, and tax planning strategies as well as the current and forecasted business economics
of our industry. Additionally, we record uncertain tax positions at their net recognizable amount, based on the amount that management
deems is more likely than not to be sustained upon ultimate settlement with the tax authorities in the domestic and international
tax jurisdictions in which we operate. On the basis of our evaluations, at December 31, 2015 and 2014, a full valuation allowance
was recorded on our net deferred tax assets and we had no material uncertain tax positions.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">If our estimates or assumptions regarding
our current and deferred tax items are inaccurate or are modified, these changes could have potentially material impacts on our
earnings.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We operate in one segment and have only
one reportable segment and one reporting unit component, which is heavy civil construction. In making this determination, the Company
considered the discrete financial information used by our Chief Operating Decision Maker (&#8220;CODM&#8221;). Based on this approach,
the Company noted that the CODM organizes, evaluates and manages the financial information around each heavy civil construction
project when making operating decisions and assessing the Company&#8217;s overall performance. The service provided by the Company,
in all instances of our construction projects, is heavy civil construction. Furthermore, we considered that each heavy civil construction
project has similar characteristics, includes similar services, has similar types of customers and is subject to similar economic
and regulatory environments which would allow aggregation of individual operating segments into one reportable segment if multiple
operating segments existed.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In addition, the Company noted that even
if our local offices were to be considered separate components of our heavy civil construction operating segment, those components
could be aggregated into a single reporting unit for purposes of testing goodwill for impairment because our local offices all
have similar economic characteristics and are similar in all of the following areas:</p>

the relevant skills required, the contract size and duration, the availability of our personnel and equipment, the makeup and level
of our existing backlog, our competitive advantages and disadvantages, prior experience, the contracting agency or customer, the
source of contract funding, anticipated start and completion dates, construction risks, penalties or incentives and general economic

backlog where we were the apparent low bidder, but had not yet been formally awarded the contract or the contract price had not

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Revenues for 2015 decreased 7.2% compared with
the prior year. This decrease is primarily attributable to the downward percent-complete revisions made to certain projects in
the first quarter of 2015, largely related to construction projects in Texas, combined with the completion of certain large projects
in Texas which were ongoing in 2014 and a $2.8 million out-of-period decrease in revenue that was recorded in the first quarter

104 contracts-in-progress which were less than 90% complete of various sizes, of different expected profitability and in various
stages of completion. The nearer a contract progresses toward completion, the more visibility we have in refining our estimate
of total revenues (including incentives, delay penalties and change orders), costs and gross profit. Thus gross profit as a percent
of revenues can increase or decrease from comparable and sequential quarters due to variations among contracts and depending upon
the stage of completion of contracts.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0">Other operating (expense) income, net, includes
50% of earnings and losses related to members&#8217; interests, gains and losses from sales of property, plant and equipment, and
other miscellaneous operating income or expense. Members&#8217; interest earnings are treated as an expense while losses are treated
as income as earnings would increase the amount in our liability account &#8220;Members&#8217; interest subject to mandatory redemption
and undistributed earnings,&#8221; and losses would decrease this liability. The decrease of $1.8 million, to other operating expense
of $1.5 million in 2015 from other operating income of $0.3 million in 2014, is primarily the result of an increase in Members&#8217;
interest earnings.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0">General and administrative expenses increased
$5.0 million during 2015 to $41.9 million from $36.9 million in 2014. This increase is primarily the result of certain non-recurring
costs related to consulting services performed and employee severance payments of $1.2 million and $2.9 million, respectively,
recognized in 2015.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0">&nbsp;</p>

<p style="margin: 0pt 0">As a percentage of revenues, general and administrative expenses increased to 6.7% in 2015 from 5.5%
in 2014. The increases in general and administrative expenses, as a percentage of revenue, are primarily the result of the non-recurring
consulting services and employee severance costs paid during 2015 and the decline in revenue mentioned above. Excluding these
non-recurring costs, general and administrative expenses would have been 6.0% in 2015.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Income taxes. </i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Our effective income tax rates for 2015 and
2014 were minimal and (13.8)%, respectively. In 2015 and in 2014, our effective income tax rate varied from the statutory rate
primarily as a result of our deferred tax asset valuation allowance.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">In order to determine that a valuation allowance
was necessary, management assessed the available positive and negative evidence to estimate whether sufficient future taxable income
would be generated to use the existing deferred tax assets. A significant piece of objective negative evidence evaluated was the
cumulative loss incurred over the three-year period ended December 31, 2015. The cumulative three-year period loss that ended in
the fourth quarter of 2015 was the result of the write-downs recorded during the past three years. Such objective evidence limits
the ability to consider other subjective evidence such as our projections for future growth. On the basis of this evaluation, as
of December 31, 2015, a full valuation allowance of $56.4 million has been recorded on our net deferred tax assets including federal
and state net operating loss carryforwards as they are not likely to be realized. The amount of the deferred tax asset considered
realizable could be adjusted if objective negative evidence is no longer present and additional weight may be given to subjective
evidence such as our projections for growth.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Net income attributable to noncontrolling interests.
</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">The decrease of $1.4 million to $3.2 million
from $4.6 million in net income attributable to noncontrolling interest owners for the year ended December 31, 2015 compared with
same period in 2014 is primarily related to net income attributable to the 50% noncontrolling interest in Myers. Approximately
$0.5 million of the $1.4 million decrease related to the accounting treatment which was the result of entering into a new agreement
in November 2015. The accounting treatment now requires noncontrolling interest earnings of certain members to flow through &#8220;Other
(expense) income, net&#8221; in our consolidated statement of operations, (refer to Note 2 in our consolidated financial statements),
and the remaining $0.9 million was primarily related to a slight decline in gross profits for the year.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Revenues for 2014 increased 20.9% compared
with prior year. This increase is primarily attributable to an increase in the number of projects in progress, largely in our Texas
and California markets. However, this increase in revenue was weaker than we anticipated, primarily in our California, Utah and
Hawaii markets. The 2013 revenues were adversely affected by the completion of large projects in Utah and to a lesser extent the
completion of significant projects in Arizona.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Gross profit increased $62.4 million in 2014
compared with the prior year. Gross margin also increased to 4.8% in 2014 from (5.4)% in 2013 primarily due to net downward revisions
of estimated revenues and gross margins on construction projects in Texas and Arizona in the prior year. In 2014, timing and weather
issues impacted some large projects in our Hawaii and California operations, while spot shortages of commodities, over-stretched
sub-contractors and vendors, and intense competition for craft labor continued to pressure our Texas operations which led to a
less than anticipated gross profit.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">While there are a number of factors which cause
the costs incurred and gross profit realized on our contracts to vary, sometimes substantially, from our original projections,
the primary factors which resulted in downward revisions in estimates in 2014 were:</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">At December 31, 2014, we had approximately
116 contracts-in-progress which were less than 90% complete of various sizes, of different expected profitability and in various
stages of completion. The nearer a contract progresses toward completion, the more visibility we have in refining our estimate
of total revenues (including incentives, delay penalties and change orders), costs and gross profit. Thus gross profit as a percent
of revenues can increase or decrease from comparable and sequential quarters due to variations among contracts and depending upon
the stage of completion of contracts.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"><i>General and administrative expenses. </i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">General and administrative expenses decreased
$4.1 million during 2014 to $36.9 million from $41.0 million in 2013. This decrease is due to certain non-recurring costs in 2013
related to employee benefit costs, as well as costs associated with the evaluation and pursuit of potential acquisition opportunities.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">As a percentage of revenues, general and administrative
expenses decreased to 5.5% in 2014 from 7.4% in 2013. The decrease in the 2014 percentage as compared to 2013 percentage is the
result of the decrease in expenses mentioned above and the result of investments made in 2013 in our information systems infrastructure
and operational and financial process improvements which allowed us to increase our efficiency without a significant increase in
general and administrative expenses.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Income taxes. </i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Our effective income tax rates for 2014 and
2013 were (13.8)% and (1.8)%, respectively. In 2014 and in 2013, our effective income tax rate varied from the statutory rate primarily
as a result of our deferred tax asset valuation allowance.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">In order to determine that a valuation allowance
was necessary, management assessed the available positive and negative evidence to estimate whether sufficient future taxable income
would be generated to use the existing deferred tax assets. A significant piece of objective negative evidence evaluated was the
cumulative loss incurred over the three-year period ended December 31, 2014. The cumulative three-year period loss that ended in
the fourth quarter of 2014 was the result of the write-downs recorded during the past three years. Such objective evidence limits
the ability to consider other subjective evidence such as our projections for future growth. On the basis of this evaluation, as
of December 31, 2014, a full valuation allowance of $37.8 million has been recorded on our net deferred tax assets including federal
and state net operating loss carryforwards as they are not likely to be realized. The amount of the deferred tax asset considered
realizable could be adjusted if objective negative evidence is no longer present and additional weight may be given to subjective
evidence such as our projections for growth.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Net income attributable to noncontrolling interests.
</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">The increase of $0.7 million to $4.6 million
from $3.9 million in net income attributable to noncontrolling interest owners for the year ended December 31, 2014 compared with
same period in 2013 is primarily related to net income attributable to the 50% noncontrolling interest in Myers. Operations at
the Myers subsidiary are conducted primarily in California where Myers has seen significant growth.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The 2015 change in Contract Capital increased
liquidity by $1.4 million. Fluctuations in our Contract Capital balance, and its components, are not unusual in our business and
are impacted by the size of our projects and changing type and mix of projects in our backlog. Our Contract Capital is particularly
impacted by the timing of new awards and related payments of performing work, and the contract billings to the customer as we
complete our projects. Contract Capital is also impacted at period-end by the timing of accounts receivable collections and accounts
payable payments for our projects.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Other assets decreased $8.1 million and $3.7
million, excluding the change in inventories, in 2015 and 2014, respectively. The decrease during 2015 is primarily the result
of the sale of our long-term receivable which we sold for $7.1 million with a loss of $1.4 million (refer to Note 1 in our consolidated
financial statements).</p>

while proceeds from the sale of property and equipment totaled $6.1 million with an associated net gain of $1.0 million. The level
of expenditures in 2015 decreased by $5.9 million from 2014 as a result of management&#8217;s efforts to optimize utilization

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During 2015, net cash used in financing activities
was $22.9 million. The drivers of financing activities cash flows were primarily due to the change of our prior credit facility
with Comerica Bank, N.A. (&#8220;Prior Credit Facility&#8221;), usage and repayment of our equipment-based revolver and distributions
to owners as discussed below.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Financing activities in 2015 consisted
of <font style="font-size: 10pt">the net repayments on our Prior Credit Facility of $34.6 million and cumulative drawdowns and
repayments on our equipment-based revolver of $14.6 million and cash received from our equipment-based term loan of $18.0 million,
net of repayments, both of which were used to fund our operating activities and replace our Prior Credit Facility. Distributions
to noncontrolling interest owners were $3.4 million for the year. Financing activities in 2014 consisted of net proceeds from
our common stock offering of $14.0 million, which was used for working capital purposes. In addition, the net drawdown on our
Prior Credit Facility of $26.8 million was used to fund our operating activities. Distributions to noncontrolling interest owners
were $1.2 million for the year.</font></p>

which decreased based on the items mentioned above. Our working capital decreased $22.0 million to $30.3 million from $52.3 million
at December 31, 2015 and 2014, respectively, primarily due to our $20.4 million net loss attributable to Sterling common stockholders
in 2015.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In addition to our available cash, cash equivalents
and cash provided by operations, from time to time, we use borrowings under our available credit or equipment-based credit facilities
to finance our capital expenditures and working capital needs.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In May 2015, the Company and its wholly-owned
subsidiaries entered into a $40.0 million loan and security agreement with Nations Equipment Finance, LLC (&#8220;Nations&#8221;),
consisting of a $20.0 million term loan and a $20.0 million Revolving Loan (combined, the &#8220;Equipment-based Facility&#8221;),
which replaced the Company&#8217;s Prior Credit Facility. The amount of the Revolving Loan that may be borrowed from time to time
is determined quarterly and may not exceed $20.0 million. In addition, the sum of the outstanding balances of the Equipment-based
Facility may not exceed the lesser of $40.0 million or 65% of the appraised value of the collateral pledged for the loans. At December
31, 2015, the Company had approximately a borrowing base of $29.6 million, which was the result of calculating 65% of the appraised
value (where appraised value equals net operating liquidated value) of the Company&#8217;s collateral. The Revolving Loan may be
utilized to provide ongoing working capital and for other general corporate purposes. At December 31, 2015, we had $18.0 million
outstanding on the Term Loan, zero drawn on the Revolving Loan, and $11.6 million of borrowings available.</p>

at an initial fixed annual rate of 12%, which is subject to (i) a decrease of up to two percentage points based on the Company's
fixed charge coverage ratio for each of the most recently ended four quarters beginning with the four quarters ending June 30,
2016; and (ii) an increase of up to two percentage points beginning December 31, 2015 based on the fixed charge coverage ratio
at the end of the following four quarters. Principal on the Term Loan is payable in 47 monthly installments (with accrued interest)
with a final payment of the then outstanding principal amount on May 29, 2019. Up to $5.0 million of the Term Loan may be prepaid
in any year, but subject to a pre-payment fee that declines as the Term Loan nears maturity. Outstanding Revolving Loans are payable
in full thirty days before the maturity date of the Term Loan.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Equipment-based Facility is secured by
all of the Company's personal property except accounts receivable, including all of its construction equipment, which forms the
basis of availability under the Revolving Loan. The Equipment-based Facility is also secured by one-half of the equipment of the
Company's 50%-owned affiliates, Road and Highway Builders, LLC and Myers &amp; Sons Construction, L.P. pursuant to a separate security
agreement with those entities. If a default occurs, Nations may exercise the Company's rights in the collateral, with all of the
rights of a secured party under the Uniform Commercial Code, including, among other things, the right to sell the collateral at
public or private sale.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The proceeds of the Term Loan of $20.0 million
and our initial draw of $14.6 million under the Revolving Loan were utilized by the Company to repay the balance outstanding and
terminate the Prior Credit Facility and for other general corporate purposes. In addition, in connection with incurring this debt,
we recorded $1.3 million in deferred debt issuance costs, which are included in &#8220;Other assets, net&#8221; in our consolidated
balance sheet and are being amortized on a straight line basis over the term of the Equipment-based Facility. In order to extinguish
the Prior Credit Facility debt, the Company incurred costs of $0.2 million, which is included in the Company&#8217;s consolidated
statement of operations.</p>

agreement, the Company&#8217;s Letter of Credit, which under our Prior Credit Facility reduced the Company&#8217;s borrowing availability,
is now collateralized with cash.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 0">Average combined borrowings under the Prior
Credit Facility and the Equipment-based Facility for the 2015 fiscal year were $25.9 million, and the largest amount of borrowings
was under the Equipment-based Facility of $34.6 million from June 5, 2015 to June 30, 2015. Average combined borrowings under the
Prior Credit Facility for the 2014 fiscal year were $16.9 million, and the largest amount of borrowings under the Prior Credit
Facility was $36.8 million on April 21, 2014.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 0">Interest expense was $3.0 million for the
2015 fiscal year compared to $1.1 million in the 2014 fiscal year. This increase in interest expense in 2015 was driven by the
increased interest rate on the new Equipment-based Facility, as described above.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Based on our average borrowings for 2015 and
our 2016 forecasted cash needs, we continue to believe that the Company has sufficient liquid financial resources to fund our requirements
for the next twelve months of operations, including our bonding requirements. Furthermore, the Company is continually assessing
ways to increase revenues and reduce costs to improve liquidity. However, in the event of a substantial cash constraint and if
we were unable to secure adequate debt financing, or we continue to incur losses, our working capital could be materially and adversely
affected. Refer to &#8220;Item 1A. Risk Factors&#8221; for further discussion of liquidity related risks.</p>

assessing ways to increase revenues and reduce costs to improve liquidity as mentioned above. During the fiscal year 2015, we scrutinized
our fleet of equipment in order to identify underutilized and non-core assets. At December 31, 2015, $1.1 million of underutilized
and non-core assets were held with the intent to sell within the next twelve months. Additionally, we experienced an increase in
our fourth quarter 2015 backlog along with several large project wins which we announced in early 2016. We will be exploring additional
capital alternatives to further strengthen our financial position in order to take advantage of this improving transportation infrastructure
market. We expect to use proceeds from these initiatives to reduce a portion of our debt and for other working capital needs.</p>

our Revolving Loan are not included in the table above as these amounts vary according to the levels of debt outstanding at any
time. Interest on our Equipment-based Facility is paid monthly in accordance with our Term Loan payment schedule and fluctuates
with the balances outstanding on our Revolving Loan during the year. In 2015, interest paid on the Equipment-based Facility and

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">To manage risks of changes in the material
prices and subcontracting costs used in submitting bids for construction contracts, we generally obtain firm quotations from our

have been provided.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">As is customary in the construction business,
we are required to provide surety bonds to secure our performance under construction contracts. Our ability to obtain surety bonds
primarily depends upon our capitalization, working capital, past performance, management expertise and reputation and certain external
factors, including the overall capacity of the surety market. Surety companies consider such factors in relationship to the amount
of our backlog and their underwriting standards, which may change from time to time. We have pledged all proceeds and other rights
under our construction contracts to our bond surety company. Events that affect the insurance and bonding markets may result in
bonding becoming more difficult to obtain in the future, or being available only at a significantly greater cost. To date, we have
not encountered difficulties or material cost increases in obtaining new surety bonds.</p>

increased levels of production and to replace retiring equipment. Management expects capital expenditures in 2016 to be similar
to the $10.8 million incurred in 2015; however, the award of a project requiring significant purchases of equipment or other factors
could result in increased expenditures.</p>

into swap contracts for diesel fuel. Due to the decline in oil and fuel prices, we did not enter into any new derivative instruments
for 2015. In addition, we retired this program when our last swap contract was settled in August 2015.</p>

joint venture partnerships in order to share expertise, risk and resources for certain highly complex projects. The venture&#8217;s
contract with the project owner typically requires joint and several liability among the joint venture partners. Although our agreements
with our joint venture partners provide that each party will assume and fund its share of any losses resulting from a project,
if one of our partners was unable to pay its share, we would be fully liable for such share under our contract with the project
owner. Circumstances that could lead to a loss under these guarantee arrangements include a partner&#8217;s inability to contribute
additional funds to the venture in the event that the project incurred a loss or additional costs that we could incur should the
partner fail to provide the services and resources toward project completion that had been committed to in the joint venture agreement.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">At December 31, 2015, there was approximately
$35 million of construction work to be completed on unconsolidated construction joint venture contracts, of which $12 million represented
our proportionate share. Due to the joint and several liability under our joint venture arrangements, if one of our joint venture
partners fails to perform, we and the remaining joint venture partners would be responsible for completion of the outstanding work.
As of December 31, 2015, we are not aware of any situation that would require us to fulfill responsibilities of our joint venture
partners pursuant to the joint and several liability under our contracts.</p>

of our sources of market risks. Outstanding indebtedness under our Prior Credit Facility incurred interest at floating rates. There
were no borrowings under this facility at December 31, 2015. As the new Equipment-based Facility does not bear interest at floating
rates, we are not subject to an impact on our results of operations from a change in interest rates. However, our interest rate
could increase by 2% based on our fixed charge coverage ratio as noted above in Item 7. Management&#8217;s Discussion and Analysis

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0 0.05in 6pt 0">We are exposed to market risk from
changes in commodity prices. In the normal course of business, we historically entered into derivative transactions, specifically
cash flow hedges, to mitigate our exposure to diesel fuel commodity price movements. We did not participate in these transactions
for trading or speculative purposes. While the use of these arrangements may have limited the benefit to us of decreases in the
prices of diesel fuel, it also limited the risk of adverse price movements. Due to the recent decline in oil and fuel prices, we
have not entered into any new derivative instruments, and we retired our hedging program when our last swap contract was settled

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the quarter ended September 30,
2015, management identified a material weakness in internal controls over financial reporting. Specifically, the Company did not
adequately review and challenge the inputs to its valuation model, including giving sufficient consideration to current experience
which differed from historical assumptions. This control deficiency could have resulted in a material adjustment to goodwill and
related disclosures in the condensed consolidated financial statements for the quarter ended September 30, 2015. Unless remediated,
this control deficiency could have resulted in a material misstatement of the Company&#8217;s condensed consolidated financial
statements that would not be prevented or detected.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In response to the material weakness identified
above, management formed a new team which included and received input from the Company&#8217;s senior operational and financial
management, and its outside advisors to review and challenge the various inputs to the revised valuation model. These inputs included,
among other things, historical actual results versus forecasted data, recent performance, backlog, and near term projects, recent
developments, strategic actions and management&#8217;s outlook for the future. The forecast and growth assumptions included, among
other things, improved project performance, continuation of a strong base market, and margin improvements driven by incremental
margin product opportunities and pursuing work in adjacent markets.</p>

of Sponsoring Organizations of the Treadway Commission (COSO) in the 2013 Internal Control-Integrated Framework. The Company&#8217;s

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0">We have audited the internal control over financial
reporting of Sterling Construction Company, Inc. (a Delaware corporation) and subsidiaries (the &#8220;Company&#8221;) as of December
31, 2015, based on criteria established in the 2013<i> Internal Control&#8212;Integrated Framework</i> issued by the Committee

internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting,
included in the accompanying Management&#8217;s Report on Internal Control over Financial Reporting. Our responsibility is to
express an opinion on the Company&#8217;s internal control over financial reporting based on our audit.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0">&nbsp;</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0">We conducted our audit in accordance with the standards
of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk,
and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable
basis for our opinion.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0">&nbsp;</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0">A company&#8217;s internal control over financial
reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with generally accepted accounting principles. A company&#8217;s internal
control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations
of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the company&#8217;s assets that could have a material effect on the financial statements.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0">&nbsp;</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0">Because of its inherent limitations, internal control
over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0">In our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in the 2013

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Sterling Construction Company, Inc. (&#8220;Sterling&#8221;
or &#8220;the Company&#8221;), a Delaware corporation, is a leading heavy civil construction company that specializes in the building
and reconstruction of transportation and water infrastructure projects in Texas, Utah, Nevada, Colorado, Arizona, California, Hawaii
and other states in which there are construction opportunities. Its transportation infrastructure projects include highways, roads,
bridges, airfields, ports and light rail. Its water infrastructure projects include water, wastewater and storm drainage systems.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Sterling owns equity interests in the following
subsidiaries: Texas Sterling Construction Co. (&#8220;TSC&#8221;); Road and Highway Builders, LLC (&#8220;RHB&#8221;); Road and
Highway Builders Inc. (&#8220;RHB Inc&#8221;); Road and Highway Builders of California, Inc. (&#8220;RHBCa&#8221;); RHB Properties,

and Sterling Hawaii Asphalt (&#8220;SHA&#8221;). TSC, RHB, RHBCa, RLW, JBC and Myers perform construction contracts, RHB Inc. produces
aggregates from a leased quarry, primarily for use by RHB, and SHA produces asphalt for use by RHB and has minimal sales to third
parties. RHBP and RLWLP are dormant entities.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Significant Accounting Policies</i></b></p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Principles of Consolidation</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The accompanying consolidated financial
statements include the accounts of subsidiaries and construction joint ventures in which the Company has a greater than 50% ownership
interest or otherwise controls such entities. For investments in subsidiaries and construction joint ventures that are not wholly-owned,
but where the Company exercises control, the equity held by the remaining owners and their portions of net income (loss) are reflected
in the balance sheet line item &#8220;Noncontrolling interests&#8221; in &#8220;Equity&#8221; and the statement of operations line
item &#8220;Noncontrolling owners&#8217; interests in earnings of subsidiaries,&#8221; respectively. All significant intercompany
accounts and transactions have been eliminated in consolidation. For all years presented, the Company had no subsidiaries where
its ownership interests were less than 50%.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Where the Company is a noncontrolling joint
venture partner, and otherwise not required to consolidate the joint venture entity, its share of the operations of such construction
joint venture is accounted for on a pro rata basis in the consolidated statements of operations and as a single line item (&#8220;Receivables
from and equity in construction joint ventures&#8221;) in the consolidated balance sheets. This method is an acceptable modification
of the equity method of accounting which is a common practice in the construction industry. Refer to Note 6<font style="color: red">
</font>for further information regarding the Company&#8217;s construction joint ventures.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Under accounting principles generally accepted
in the United States (&#8220;GAAP&#8221;), the Company must determine whether each entity, including joint ventures in which it
participates, is a variable interest entity (&#8220;VIE&#8221;). This determination focuses on identifying which owner or joint
venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the entity
or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect of
requiring the Company to consolidate the entity in which we have a noncontrolling variable interest. Refer to Note 3 for further
information regarding the Company&#8217;s consolidated VIE.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Use of Estimates</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The preparation of financial statements
in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities,
the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues
and expenses during the reporting period. Certain of the Company&#8217;s accounting policies require higher degrees of judgment
than others in their application. These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion
method, the valuation of long-term assets (including goodwill), and income taxes. Management continually evaluates all of its estimates
and judgments based on available information and experience; however, actual results could differ from these estimates.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"><i>Revenue Recognition</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company is a general contractor which
engages in various types of heavy civil construction projects principally for public (government) owners. Credit risk is minimal
with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing
work on such projects. While most public contracts are subject to termination at the election of the government entity, in the
event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related
costs. Credit risk with private owners is minimized because of statutory mechanics liens, which give the Company high priority
in the event of lien foreclosures following financial difficulties of private owners. Refer to Note 16 for further information
regarding the Company&#8217;s concentration of risk.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"></p>

    <!-- Field: /Page -->

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Revenues are recognized on the percentage-of-completion
method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost
measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs
include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such
as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses
are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Changes in job performance, job conditions and estimated profitability, including those changes arising
from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized
in the period in which the revisions are determined.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Changes in estimated revenues and gross
margin during the year ended December 31, 2015 resulted in a net charge of $9.7 million included in operating loss, or $0.50 per
diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders.
Changes in estimated revenues and gross margin during the year ended December 31, 2014 resulted in a net charge of $9.1 million
included in operating loss, or $0.50 per diluted share attributable to Sterling common stockholders, included in net loss attributable
to Sterling common stockholders. Changes in estimated revenues and gross margin during the year ended December 31, 2013 resulted
in a net charge of $57.6 million included in operating loss, or $3.46 per diluted share attributable to Sterling common stockholders,
included in net loss attributable to Sterling common stockholders.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Change orders are modifications of an original
contract that effectively change the existing provisions of the contract without adding new scope or terms. Change orders may include
changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of
the work. Either we or our customers may initiate change orders.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company considers unapproved change
orders to be contract variations for which we have customer approval for a change of scope but a price change associated with the
scope change has not yet been agreed upon. Costs associated with unapproved change orders are included in the estimated cost to
complete the contracts and are treated as project costs as incurred. The Company recognizes revenue equal to costs incurred on
unapproved change orders when realization of price approval is probable. Unapproved change orders involve the use of estimates,
and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting
periods to reflect changes in estimates or final agreements with customers. Change orders that are unapproved as to both price
and scope are evaluated as claims.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company considers claims to be amounts
in excess of agreed contract prices that we seek to collect from our customers or others for customer-caused delays, errors in
specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope
and price, or other causes of unanticipated additional contract costs. Claims are included in the calculation of revenue when realization
is probable and amounts can be reliably determined to the extent costs are incurred. To support these requirements, the existence
of the following items must be satisfied: 1. The contract or other evidence provides a legal basis for the claim; or a legal opinion
has been obtained, stating that under the circumstances there is a reasonable basis to support the claim; 2. Additional costs are
caused by circumstances that were unforeseen at the contract date and are not the result of deficiencies in the contractor&#8217;s
performance; 3. Costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work
performed; and 4. The evidence supporting the claim is objective and verifiable, not based on management&#8217;s feel for the situation
or on unsupported representations. Revenues in excess of contract costs incurred on claims is recognized when an agreement is reached
with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract.
Costs associated with claims are included in the estimated costs to complete the contracts and are treated as project costs when
incurred.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">There were $1.6 million in costs and estimated
earnings in excess of billings at December 31, 2015 and $3.5 million in costs and estimated earnings in excess of billing at December
31, 2014, for contract change orders not approved by the customer. In addition, the Company recorded $5.2 million in revenues
related to claims during the year ended December 31, 2015, and did not record revenues related to claims during the years ended
December 31, 2014 and 2013.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our contracts generally take 12 to 36 months
to complete. The Company generally provides a one to two-year warranty for workmanship under its contracts when completed. Warranty
claims historically have been insignificant.</p>

on these contracts.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Reclassification</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Certain amounts in prior years&#8217; financial
statements have been reclassified to conform to the presentation used in the year ended December 31, 2015.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Financial Instruments </i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The fair value of financial instruments
is the amount at which the instrument could be exchanged in a current transaction between willing parties. The Company&#8217;s
financial instruments are cash and cash equivalents, restricted cash used as collateral for a letter of credit and restricted cash
maintained in an escrow account, short-term and long-term contracts receivable, accounts payable, notes payable, a revolving loan
(the &#8220;Revolving Loan&#8221;) with Nations Fund I, LLC and Nations Equipment Finance, LLC, as administrative agent and collateral
agent for the lender (&#8220;Nations&#8221;), a term loan (the &#8220;Term Loan&#8221;) with Nations (combined, the &#8220;Equipment-based
Facility&#8221;), and an earn-out liability related to the acquisition of JBC.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The recorded values of cash and cash equivalents,
restricted cash, short-term contracts receivable and accounts payable approximate their fair values based on their liquidity and/or
short-term nature. The recorded value of the long-term contract receivable was based on the amount of future cash flows discounted
using the creditor&#8217;s borrowing rate and such recorded value approximated fair value.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company provides credit in the normal
course of business, principally to public (government) owners, and performs ongoing credit evaluations, as deemed necessary, but
generally does not require collateral to support such receivables.&nbsp; In an effort to reduce its credit exposure, as well as
accelerate its cash flows, in August 2015, the Company completed the sale, on a non-recourse basis, of its only long-term contract
receivable pursuant to a factoring agreement with a related party. The Company received approximately $7.1&nbsp;million upon the
closing of this transaction and recorded a loss of approximately $1.4 million in &#8220;Other operating (expense) income, net.&#8221;&nbsp;
As such, we did not have a long-term contract receivable at December 31, 2015.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Refer to Note 2 regarding the fair value
of an earn-out liability along with the most current amendments, and Note 9 regarding the fair value of the Revolving Loan and
the Term Loan. The Company also has long-term notes payable of $2.2 million related to machinery and equipment purchased which
have payment terms ranging from 3 to 5 years and associated interest rates ranging from 3.12% to 6.29%. The fair value of these
notes payable approximates their book value. The Company does not have any off-balance sheet financial instruments other than operating
leases (Refer to Note 12).</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In order to assess the fair value of the
Company&#8217;s financial instruments, the Company uses the fair value hierarchy established by GAAP which prioritizes the inputs
used in valuation techniques into the following three levels:</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Contracts receivable are generally based
on amounts billed to the customer. At December 31, 2015 and 2014, contracts receivable included $19.8 million and $16.4 million
of retainage, respectively, discussed below, which is being withheld by customers until completion of the contracts, and at December
31, 2015, and 2014, there were no unbilled receivables on contracts completed or substantially complete at that date. All contracts
receivable include only balances approved for payment by the customer.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Many of the contracts under which the Company
performs work contain retainage provisions. Retainage refers to that portion of billings made by the Company but held for payment
by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained
by customers under such provisions are fully collectible. Retainage on active contracts is classified as a current asset regardless
of the term of the contract and is generally collected within one year of the completion of a contract.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">There are certain contracts that are completed
in advance of full payment. When the receivable will not be collected within our normal operating cycle, we consider it a long-term
contract receivable and it is recorded in &#8220;Other assets, net&#8221; in our balance sheet. In August 2015, the Company completed
the sale, on a non-recourse basis, of its only long-term contract receivable pursuant to a factoring agreement with a related party.
As such, there was no outstanding long-term contract receivable at December 31, 2015. At December 31, 2014, there was $5.0 million
recorded. We considered the credit quality of the borrower to assess the appropriate discount rate applied and continuously monitored
the borrower&#8217;s credit quality. The long-term contract receivable was historically discounted at 4.25% and recorded at fair
value. Interest income related to this receivable was $0.2 million, $0.4 million and $0.3 million for the years ended December
31, 2015, 2014 and 2013, respectively.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Contracts receivable are written off based
on individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. There was an immaterial
amount of bad debt expense recorded in 2015 and no bad debt expense recorded in 2014. In 2013, the Company wrote off $1.8 million
of contracts receivable to bad debt expense which was recorded in &#8220;Other operating (expense) income, net.&#8221; During 2014,
we recovered $1.0 million of this $1.8 million.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">At year-end, the Company performs a review
of outstanding contracts receivable, historical collection information and existing economic conditions to determine if there
are potential uncollectible receivables. At December 31, 2015 and 2014, our allowance for doubtful accounts against contracts
receivable was immaterial and zero, respectively.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">As is customary, we have agreed to indemnify

and $7.4 million, respectively. Inventories consist primarily of concrete, aggregate and millings which are primarily expected
to be utilized on construction projects in the future. A small portion is sold to third parties. The cost of inventory includes
labor, trucking and other equipment costs.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 4.5pt 0 0">We lease property and equipment in the
ordinary course of our business. Our leases have varying terms. Some may include renewal options, escalation clauses, restrictions,
penalties or other obligations that we consider in determining minimum lease payments. The leases are classified as either operating
leases or capital leases, as appropriate.</p>

<p style="font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><i>Equipment under Capital Leases</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company&#8217;s policy is to account
for capital leases, which transfer substantially all the benefits and risks incident to the ownership of the leased property to
the Company, as the acquisition of an asset and the incurrence of an obligation. Under this method of accounting, the recorded
value of the leased asset is amortized principally using the straight-line method over its estimated useful life and the obligation,
including interest thereon, is reduced through payments over the life of the lease. Depreciation expense on equipment subject to
capital leases and the related accumulated depreciation is included with that of owned equipment. The Company had one capital lease
at December 31, 2015 of $0.5 million recorded in &#8220;Long-term debt, net of current maturities&#8221; and &#8220;Current maturities
of long-term debt,&#8221; as applicable, in our consolidated balance sheet and had no capital leases during the years ended December

fees paid to the lender and related professional fees such as legal fees related to drafting of loan agreements. During 2015, the
Company capitalized an additional $1.3 million in loan fees paid to Nations in connection with incurring the new debt, discussed
further in Note 9. These capitalized fees are amortized on a straight-line basis over the term of the Equipment-based Facility.
Unamortized costs were $1.1 million and $0.2 million at December 31, 2015 and 2014 and are attributable to the Equipment-based
Facility and Prior Credit Facility, respectively (Refer to Note 9). Loan cost amortization expense for the years ended December

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Goodwill represents the excess of the cost
of companies acquired over the fair value of their net assets at the dates of acquisition. GAAP requires that: (1) goodwill and
indefinite lived intangible assets not be amortized, (2) goodwill is to be tested for impairment at least annually at the reporting
unit level and (3) intangible assets deemed to have an indefinite life are to be tested for impairment at least annually by comparing
the fair value of these assets with their recorded amounts. Refer to Note 8 for our disclosure regarding goodwill impairment testing.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">When events or changes in circumstances
indicate that long-lived assets may be impaired, an evaluation is performed. The evaluation would be based on estimated undiscounted
cash flows associated with the assets as compared to the asset&#8217;s carrying amount to determine if a write-down to fair value
is required. There was an immaterial impairment in 2015 related to assets held for sale, and no impairment in 2014 and 2013, and
management believes that there are no additional events or changes in circumstances which have indicated that other long-lived
assets may be impaired. See Note 7 for more information regarding our assets held for sale and immaterial impairment charge in

one reportable segment and one reporting unit component, which is heavy civil construction. In making this determination, the Company
considered the discrete financial information used by our Chief Operating Decision Maker (&#8220;CODM&#8221;). Based on this approach,
the Company noted that the CODM organizes, evaluates and manages the financial information around each heavy civil construction
project when making operating decisions and assessing the Company&#8217;s overall performance. The service provided by the Company,
in all instances of our construction projects, is heavy civil construction. Furthermore, we considered that each heavy civil construction
project has similar characteristics, includes similar services, has similar types of customers and is subject to similar economic
and regulatory environments which would allow aggregation of individual operating segments into one reportable segment if multiple
operating segments existed.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company noted that even if our local
offices were to be considered separate components of our heavy civil construction operating segment, those components could be
aggregated into a single reporting unit for purposes of testing goodwill for impairment under Accounting Standards Codification
280 and EITF D-101 because our local offices all have similar economic characteristics and are similar in all of the following

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We determine deferred income tax assets
and liabilities using the balance sheet method. Under this method, the net deferred tax asset or liability is determined based
on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities
and gives current recognition to changes in tax rates and laws. Valuation allowances are established when necessary to reduce deferred
tax assets to the amount expected to be realized. We recognize the financial statement benefit of a tax position only after determining
that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the
more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than

is administered by the Compensation Committee of the Board of Directors. The Compensation Committee may reward employees and non-employees
with various types of awards including, but not limited to, warrants, stock options, common stock, and unvested common stock (or
restricted stock) vesting on service, performance or market criteria. The Company recognizes expense based on the grant-date fair
value of the service award and amortizes the award based on accelerated or straight line methods. Awards based on performance vesting
are subsequently remeasured at each reporting date through the settlement date. Awards that vest based on market criteria are valued
using a valuation model that incorporates the probability of the Company meeting the stated criteria, such as the Monte-Carlo simulation,
and the expense is amortized on a straight line basis over the term of the agreement.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Upon the vesting of unvested common stock the
Company may withhold shares, based on the employee&#8217;s election, in order to satisfy federal tax withholdings. The shares held
by the Company are considered constructively retired and are retired shortly after withholding. The Company then remits the withholding
taxes required. Refer to Note 14 for further information regarding the stock-based incentive plans.</p>

Standards Board (&#8220;FASB&#8221;) issued its new lease accounting guidance in Accounting Standards Update (&#8220;ASU&#8221;)
No. 2016-02, Leases (Topic 842).&nbsp; Under the new guidance, lessees will be required to recognize for all leases (with the exception
of short-term leases) a lease liability, which is a lessee&#8217;s obligation to make lease payments arising from a lease, measured
on a discounted basis and a right-of-use asset, which is an asset that represents the lessee&#8217;s right to use, or control the
use of, a specified asset for the lease term.&nbsp; The new standard is effective for annual periods beginning after December 15,
2018, including interim periods within those fiscal years.&nbsp; The Company is currently evaluating the impact of the adoption
of this ASU to the Company&#8217;s consolidated financial statements and related disclosures.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In November 2015, the FASB issued ASU 2015-17,
&#8220;Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.&#8221; Under ASU 2015-17, a reporting entity is
required to classify deferred tax assets and liabilities as noncurrent in a classified statement of financial position. The update
is effective for public business entities issuing financial statements for the annual periods beginning after December 15, 2015,
and interim periods within those annual periods. The Company retrospectively adopted the provisions of this ASU at December 31,
2015. Accordingly, $1.2 million of net deferred tax assets have been reclassified from current to non-current in the accompanying
consolidated balance sheet as of December 31, 2014. The net deferred tax assets include an offsetting valuation allowance; therefore,
there was no change to the consolidated balance sheet as of December 31. Refer to Note 10.</p>

guidance states that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently
amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there
are any outstanding borrowings on the line-of-credit arrangement. The Company is currently accounting for its debt issuance costs
for its Term Loan and line-of-credit Revolver Loan in this manner and would only expect a change in presentation of the deferred
amounts related to the Term Loan upon adoption as required by ASU 2015-03. See below for the discussion related to ASU 2015-03.</p>

Buenting revised the Second Amended and Restated Operating Agreement entered into on April 27, 2012 and their Management Agreement
entered into on February 1, 2012. The Third Amended and Restated Operating Agreement and the amended Management Agreement eliminated
the buy/sell option and instead included the obligation for the Company to purchase Mr. Buenting&#8217;s interest upon his death
or permanent disability for $20 million or $18 million (subsequently increased to $20 million), respectively. In the event of Mr.
Buenting&#8217;s death or permanent disability, his estate representative, trustee or designee shall become the selling representative
and sell his 50% interest to the Company. In order to fund the purchase of Mr. Buenting&#8217;s interest, the Company has purchased
term life insurance with a payout of $20 million in the event of Mr. Buenting&#8217;s death. The Company will be the beneficiary
and will also pay the premiums related to this life insurance contract. The life insurance proceeds of $20 million shall be used
as full payment for Mr. Buenting&#8217;s interest in the occurrence of his death. On June 2, 2015, the Company purchased an insurance
policy with a five-year term on Mr. Buenting that provides a lump sum disability benefit in the principal sum of $20 million. &nbsp;In
the event of Mr. Buenting&#8217;s permanent total disability, the principal sum becomes payable to the Company, and in turn the
Company is obligated to use the proceeds of the policy to purchase Mr. Buenting&#8217;s 50% member&#8217;s interest in RHB in accordance
with the terms of the amended agreements. No other transfer of member&#8217;s interest is permitted other than to the selling representative
in the event of Mr. Buenting&#8217;s death or permanent disability. The amended agreements were entered into in order to eliminate
the earnings-per-share volatility caused by the buy/sell option.</p>

of JBC and the Company agreed to amend the above mentioned earn-out agreement in order to reduce the Company&#8217;s recorded liability
at that time, while providing the former owner, who at the time was the chief executive officer of JBC, a greater incentive to
meet earnings benchmarks. The amendment resulted in a reduction of $0.6 million in the Company&#8217;s earn-out liability, thereby
reducing the total earn-out liability to $1.4 million on December 31, 2013. As part of the amendment, a payment of $0.8 million
was made during the first quarter of 2014. The amendment increased the total available earn-out from $5.0 million to $10.0 million
if certain EBITDA benchmarks are met. The amendment extended the earn-out period through December 31, 2017 and reduced the benchmark
EBITDA for 2014 and 2015 to $1.5 million and increased it to $2.0 million in 2016 and 2017. This earn-out liability continues to
be classified as a Level 3 fair value measurement and the unobservable inputs continue to be the forecasted EBITDA for the periods
after the period being reported on through December 31, 2017. There was no yearly excess forecasted EBITDA in our calculation at
December 31, 2015 of the minimum EBITDA benchmarks for the years 2016 through 2017. The discounted present value of the additional
purchase price was estimated to be $0.3 million as of December 31, 2014. The undiscounted earn-out liability as of December 31,
2015 is minimal and could increase by $9.3 million if EBITDA during the earn-out period increases $18.5 million or more and could
decrease by the full amount of the liability for the year if EBITDA does not exceed the minimum threshold for that year. Each year
is considered a discrete earnings period and future losses by JBC, if any, would not reduce the Company&#8217;s liability in years
in which JBC has exceeded its earnings benchmark. Any significant increase or decrease in actual EBITDA compared to the forecasted
amounts would result in a significantly higher or lower fair value measurement of the additional purchase price. This liability
is included in other long-term liabilities on the accompanying consolidated balance sheets. As part of recording the present value
of this liability, the Company incurs accreted interest expense for the passage of time until the time of settlement. The Company
incurred accreted interest expense of $0.3 million for the year ended December 31, 2014. As part of the updated EBITDA forecast,
the Company reduced its liability to zero and recorded interest income of $0.3 million in the first quarter of 2015. There has
been minimal change in the value of this liability; therefore, the interest income was $0.3 million for the year ended December
31, 2015.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 13.7pt; margin: 6pt 0">Under GAAP, the Company must determine whether
each entity, including joint ventures in which it participates, is a VIE. This determination focuses on identifying which owner
or joint venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the
entity or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect
of requiring the Company to consolidate the entity in which we have a noncontrolling variable interest. Where the Company has determined
that it is appropriate to consolidate a VIE which it owns a 50% or less interest, the equity held by the remaining owners and their
portions of net income (loss) are reflected in the balance sheet line item &#8220;Noncontrolling interests&#8221; in &#8220;Equity&#8221;
and the statement of operations line item &#8220;Noncontrolling owners&#8217; interests in earnings of subsidiaries,&#8221; unless
the equity interest is deemed to be mandatorily redeemable. Refer to Note 2 regarding the Company&#8217;s mandatorily redeemable
obligations.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 13.7pt; margin: 6pt 0">On August 1, 2011, the Company purchased a
50% limited partner interest in Myers. Myers is a construction limited partnership located in California and was acquired in order
to expand the geographic scope of the Company&#8217;s operations into California. The Company has determined that Myers is a VIE
for which the Company is the primary beneficiary and has consolidated Myers into the Company&#8217;s financial statements.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 13.7pt; margin: 6pt 0">The determination that Myers is a VIE and
that the Company is the primary beneficiary is primarily due to the following factors. The partnership agreement requires that
Sterling provide funding as needed, when available, to the limited partnership. In addition, the partnership is relying on the
Company&#8217;s surety bonding capacity in order to bid and perform large construction jobs resulting in the Company having joint
and several liability for completion of such jobs, and the Company will provide management to the partnership to oversee bidding
and management of larger projects. Although the Company will receive 50% of the income from the partnership, it may suffer more
than 50% of any losses as a result of its obligation to provide funding and its obligations under the surety bonds. Because the
Company exercises primary control over activities of the partnership and it is exposed to the majority of potential losses of
the partnership, the Company consolidated Myers within the Company&#8217;s financial statements from August 1, 2011, the date
of acquisition.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We participate in joint ventures with other
large construction companies and other partners, typically for large, technically complex projects, including design-build projects,
when it is desirable to share risk and resources in order to seek a competitive advantage or when the project is too large for
us to obtain sufficient bonding. Joint venture partners typically provide independently prepared estimates, furnish employees and
equipment, enhance bonding capacity and often also bring local knowledge and expertise. We select our joint venture partners based
on our analysis of their construction and financial capabilities, expertise in the type of work to be performed and past working
relationships with us, among other criteria.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We participate in various construction
joint venture partnerships. Generally, each construction joint venture is formed to accomplish a specific project and is jointly
controlled by the joint venture partners. The joint venture agreements typically provide that our interests in any profits and
assets, and our respective share in any losses and liabilities that may result from the performance of the contract are limited
to our stated percentage interest in the venture. We have no significant commitments beyond completion of the contract with the
customer.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Joint venture contracts with project owners
typically impose joint and several liability on the joint venture partners. Although our agreements with our joint venture partners
provide that each party will assume and pay its share of any losses resulting from a project, if one of our partners is unable
to pay its share, we would be fully liable under our contract with the project owner. Circumstances that could lead to a loss under
these guarantee arrangements include a partner&#8217;s inability to contribute additional funds to the venture in the event that
the project incurs a loss or additional costs that we could incur should the partner fail to provide the services and resources
toward project completion that had been committed to in the joint venture agreement. Historically, the Company has not incurred
a liability related to the nonperformance of a joint venture partner.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Under a joint venture agreement, one partner
is typically designated as the sponsor or manager. The sponsoring partner typically provides all administrative, accounting and
most of the project management support for the project and generally receives a fee from the joint venture for these services.
We have been designated as the sponsoring partner in certain of our current joint venture projects and are a non-sponsoring partner
in others.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Under GAAP, the Company must determine
whether each joint venture in which it participates is a variable interest entity. This determination focuses on identifying which
joint venture partner, if any, has the power to direct the activities of a joint venture and the obligation to absorb losses of
the joint venture or the right to receive benefits from the joint venture in excess of their ownership interests and could have
the effect of requiring us to consolidate joint ventures in which we have a noncontrolling variable interest. At December 31, 2015,
we had no participation in a joint venture where we had a material non-majority variable interest.</p>

the sale of a parcel of land located in Harris County, Texas to Joseph P. Harper, Sr., former President and Chief Operating Officer
of the Company. Proceeds received were approximately $2.4 million. Upon completion of the sale, the Company recognized a gain of
approximately $1.4 million included in &#8220;Other operating (expense) income, net&#8221; on the consolidated statement of operations.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company intends to sell certain construction
and transportation equipment during the next twelve months. At December 31, 2015, the Company&#8217;s consolidated balance sheet
included assets held for sale with a carrying value of approximately $1.1 million, net of an immaterial impairment charge, which
have been reclassified out of &#8220;Property and equipment, net,&#8221; and into &#8220;Other current assets.&#8221;</p></div><p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Goodwill represents the excess of the cost
of companies acquired over the fair value of their net assets at the dates of acquisition. GAAP requires that goodwill not be amortized
and that goodwill is to be tested for impairment at least annually at the reporting unit level. The Company tests for goodwill
impairment annually on October 1<sup>st</sup> unless impairment triggers exist at interim periods. There are two steps involved
in the testing of goodwill, excluding a qualitative analysis. The first step compares the book value of the Company&#8217;s stock
(stockholders&#8217; equity or net assets) to the adjusted fair market value of those shares. If the adjusted fair value of the
stock is greater than the calculated book value of the stock, goodwill is deemed not to be impaired and no further testing is required.
If the adjusted fair value is less than the calculated book value, then step two of determining the fair value of net assets must
be taken to determine the impairment amount.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">To determine the fair value of the Company&#8217;s
net assets, the Company used the weighted average of the following valuation techniques: the market approach, which uses market
capitalization information plus a control premium and an income approach, which uses a discounted cash flow methodology. The market
approach includes level one fair value inputs, such as the Company&#8217;s stock price, at the date of our test, and level two
fair value inputs, such as the control premiums based on prior year sales transactions of construction contractors and engineering
services, similar sized transactions based on the Company&#8217;s market capitalization, and all-inclusive total industries transactions.
The income approach includes level three inputs such as the Company&#8217;s calculated weighted average cost of capital and future
income projections that include assumptions about revenue and gross profit growth, along with other assumptions.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the first and third quarters of
2015, the Company noted there was an impairment trigger present during these interim periods and performed step one of the impairment
test discussed above. Based on the results of our goodwill impairment tests, we concluded that there was not an impairment of goodwill
during these periods. In addition, as part of our 2015 and 2014 annual tests, we determined that the fair value of the Company&#8217;s
equity continues to be more than the carrying value of the Company&#8217;s equity by approximately 21% and 19%, respectively.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">At December 31, 2015, we had goodwill with
a remaining carrying amount of approximately $54.8 million. Testing under step one in 2014 and 2013 also did not indicate that
the adjusted fair value of the Company&#8217;s stock was less than its book value.</p></div><p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In May 2015, the Company and its wholly-owned
subsidiaries entered into a $40.0 million loan and security agreement with Nations, consisting of a $20.0 million Term Loan and
a $20.0 million Revolving Loan (combined, the &#8220;Equipment-based Facility&#8221;), which replaced its Prior Credit Facility.
The amount of the Revolving Loan that may be borrowed from time to time is determined quarterly and may not exceed $20.0 million.
In addition, the sum of the outstanding balances of the Equipment-based Facility may not exceed the lesser of $40.0 million or
65% of the appraised value of the collateral pledged for the loans. At December 31, 2015, the Company had approximately a borrowing
base of $29.6 million, which was the result of calculating 65% of the appraised value (where appraised value equals net operating
liquidated value) of the Company&#8217;s collateral. The Revolving Loan may be utilized by the Company to provide ongoing working
capital and for other general corporate purposes.</p>

at an initial fixed annual rate of 12%, which is subject to (i) a decrease of up to two percentage points based on the Company's
fixed charge coverage ratio for each of the most recently ended four quarters beginning with the four quarters ending June 30, 2016;
and (ii) an increase of up to two percentage points beginning December 31, 2015 based on the fixed charge coverage ratio at the
end of the following four quarters. Principal on the Term Loan is payable in 47 monthly installments (with accrued interest) with
a final payment of the then outstanding principal amount on May 29, 2019. Up to $5.0 million of the Term Loan may be prepaid in
any year, but subject to a pre-payment fee that declines as the Term Loan nears maturity. Outstanding Revolving Loans are payable
in full thirty days before the maturity date of the Term Loan.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Equipment-based Facility is secured
by all of the Company's personal property except accounts receivable, including all of its construction equipment, which forms
the basis of availability under the Revolving Loan. The Equipment-based Facility is also secured by one-half of the equipment of
the Company's 50%-owned affiliates, Road and Highway Builders, LLC and Myers &amp; Sons Construction, L.P. pursuant to a separate
security agreement with those entities. If a default occurs, Nations may exercise the Company's rights in the collateral, with
all of the rights of a secured party under the Uniform Commercial Code, including, among other things, the right to sell the collateral
at public or private sale.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The proceeds of the Term Loan of $20.0
million and our initial draw of $14.6 million under the Revolving Loan were utilized by the Company to repay the balance outstanding
and terminate the Prior Credit Facility and for other general corporate purposes. In addition, in connection with incurring this
debt, we recorded $1.3 million in deferred debt issuance costs which are included in &#8220;Other assets, net&#8221; in our consolidated
balance sheet, which is being amortized on a straight line basis over the term of the Equipment-based Facility.</p>

agreement, the Company&#8217;s Letter of Credit, which under our Prior Credit Facility reduced the Company&#8217;s borrowing availability,
is now collateralized with cash. The aggregate amount of letters of credit outstanding under the Prior Credit Facility was $3.0
million at December 31, 2014, which reduced availability under the Prior Credit Facility. Refer to Note 4 for more information
regarding the Company&#8217;s cash and cash equivalents including restricted cash used as collateral.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 0">Interest expense related to our Equipment-based
Facility was $2.9 million for the 2015 fiscal year compared to $1.0 million in the 2014 fiscal year. This increase in interest
expense in 2015 was driven by the increased interest rate on the new Equipment-based Facility agreement, as described above.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">At December 31, 2015, the Company had

2014, the Company had $34.6 million outstanding under the Prior Credit Facility and $2.4 million of borrowings available.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Management assesses the available positive
and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets.
A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended
December 31, 2015. The cumulative three-year period loss that remained at December 31, 2015 was the result of write-downs recorded
during the past three years. Such objective evidence limits the ability to consider other subjective evidence such as our projections
for future growth. On the basis of this evaluation, as of December 31, 2015, a valuation allowance of $56.4 million has been recorded
on the net deferred tax assets including federal and state net operating losses as they are not likely to be realized. The amount
of the deferred tax asset considered realizable, however, could be adjusted in the future if objective negative evidence or cumulative
losses are no longer present and additional weight may be given to subjective evidence such as our projections for growth.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">If our assumptions change and we determine
we will be able to realize these deferred tax assets, the tax benefits relating to any reversal of the valuation allowance on deferred
tax assets as of December 31, 2015, will be accounted for as follows: approximately $46.8 million will be recognized as a reduction
of income tax expense and $9.6 million will be recorded as an increase in equity.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">On September 13, 2013, the U.S. Treasury
Department and the I.R.S. issued final regulations that address costs incurred in acquiring, producing, or improving tangible property
(the "tangible property regulations"). The tangible property regulations are generally effective for tax years beginning
on or after January 1, 2014. The Company intends to adopt the tax treatment of expenditures to improve tangible property and the
capitalization of inherently facilitative costs to acquire tangible property as of January 1, 2014. The tangible property regulations
will require the Company to make additional tax accounting method changes as of January 1, 2014; however, management does not anticipate
the impact of these changes to be material to the Company&#8217;s consolidated financial position, its results of operations, or
both.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">As a result of the Company&#8217;s analysis,
management has determined that the Company does not have any material uncertain tax positions. The Company&#8217;s policy is to
recognize interest related to any underpayment of taxes as interest expense, and penalties as administrative expenses. No interest
or penalties have been accrued at December 31, 2015 or 2014. The Company&#8217;s U.S. federal income tax returns for 2012 and later
years are open and subject to examination by the I.R.S. In addition, the Company&#8217;s state income tax returns for 2011 and

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In October 2008, the Company announced
a share-repurchase program to purchase up to $5 million in shares of common stock. In August 2010, the Company announced an increase
to the share-repurchase program to purchase an additional $5 million in shares of common stock, for a total up to $10 million.
The specific timing and amount of repurchase will vary based on market conditions, securities law limitations and other factors.
There were no shares repurchases in 2015 and 2014 related to the share-repurchase program.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company accounts for the repurchase
of treasury shares under the cost method. When shares are repurchased, cash is paid and the treasury stock account is debited for
the price paid. Under the cost method, retirement of treasury stock would result in a debit to the common stock account for the
original par value, a debit to additional paid-in capital for the excess between the par value and the original sales price, a
debit to retained earnings for any excess amounts paid above the original sales price and a credit to the treasury stock account
for the price paid.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Forfeited shares are generally the result
of an employee&#8217;s separation from the Company. Forfeitures of our service-, performance- and market-based share awards are
discussed below. Such stock is held briefly as treasury stock and canceled during the year. At December 31, 2015 and 2014, there
was no treasury stock held by the Company.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Upon the vesting of unvested common stock
(or restricted stock) the Company may withhold shares, based on the employee&#8217;s election, in order to satisfy federal tax
withholdings. The shares held by the Company are considered constructively retired and are retired shortly after withholding. The
Company then remits the withholding taxes required by the taxing agencies. During 2015 and 2014, there were 96,076 and 8,120 shares
withheld for tax purposes and retired.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"><b><i>Stock-based Compensation and Grants</i></b></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company has a stock-based incentive
plan that is administered by the Compensation Committee of the Board of Directors (the &#8220;2001 Plan&#8221;). The 2001 Plan
is in effect until May 2021 as a result of a May 2011 amendment to extend its term for an additional ten years. The 2001 Plan provides
for the issuance of stock awards for up to 1,900,000 shares of the Company&#8217;s common stock. The Compensation Committee may
reward employees and non-employees with various types of awards including but not limited to warrants, stock options, common stock,
and unvested common stock (or restricted stock) vesting on service, performance or market criteria.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">At December 31, 2015, there were 614,921
shares of common stock available under the 2001 Plan. All shares under the plan are available for issuance pursuant to future stock-based
compensation awards.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">There were no options outstanding at December
31, 2015 and 2014 and no shares are, or will be, available for grant under the Company&#8217;s other option plans, all of which
have been terminated.</p>

awards discussed above, the Company also awarded performance-based awards. In 2013, the Company issued 100,000 shares of unvested
common stock to the Company&#8217;s former CEO which were accelerated and distributed to him upon his separation in January 2015.
In 2014 and 2015, there were a total of 7,500 and 10,000 performance-based shares issued, respectively. In 2015, 13,750 of performance
based shares were forfeited. In order to recognize compensation expense for these performance based shares, the Company must assess,
at each reporting period, whether it is probable that the performance condition will be met. These shares must also be re-valued
at each reporting period until they vest. At December 31, 2015 and 2014, the Company assessed that it would not be probable that
the performance conditions would be met, as such; no expense was incurred during either year.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">On January 1, 2015, the Company launched
a long- and short-term incentive program for certain employees.&nbsp;&nbsp;The short-term incentive plan is paid in cash if certain
short-term achievements are met and the long-term incentive plan is paid with the Company&#8217;s stock if certain long-term achievements
are met.&nbsp;&nbsp;The stock-based awards are awarded based in two parts; 50% is based on completing a service period of three
years and 50% is based on the level of achievement of the Company&#8217;s total shareholder return (&#8220;TSR&#8221;) compared
to the TSR of a designated peer group over a three-year period or a market based stock award.&nbsp;&nbsp;The service based awards
are recorded as usual; however, the market-based awards of 86,483 shares were valued using a Monte Carlo simulation and their expense
was included in the $1.2 million of total unvested and market-based awards discussed below. During the year ended December 31,
2015, 55,419 of these shares were forfeited and amortization expense was adjusted.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">At December 31, 2015, total unrecognized
compensation cost related to unvested common and market-based stock was $3.1 million. This cost is expected to be recognized over
a weighted average period of 1.6 years. Compensation expense for unvested common stock (or restricted stock) and market-based grants
were $1.2 million in 2015, and $0.8 million in each of 2014 and 2013. There were no proceeds received by the Company from the exercise
of options in 2015 as there were no options outstanding in 2015, and in 2014 and 2013, the proceeds received were less than $0.1
million for each of these years.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company&#8217;s operating revenues
tend to be somewhat higher in the summer months which are typically due to warmer and dryer weather conditions. Our second and
third quarter revenues and results of operations typically reflect these seasonal trends. However, from time to time, the Company&#8217;s
operating results are significantly affected by certain transactions or events that management believes are not indicative or representative
of our results.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company recorded downward percent-complete
revisions to certain projects in the first quarter of 2015, largely related to construction projects in Texas, and there was unseasonably
more rainfall during second quarter of 2015, also in Texas, which caused declines in productivity and unanticipated delays during
this quarter.&nbsp;</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the third and fourth quarters of
2014, the Company recorded changes in estimated revenues and gross margin which resulted in net charges of $4.5 million and $9.5
million, respectively. Gross profit was depressed by downward revisions of gross profit on problem projects, the majority of which
are being constructed in Texas, primarily due to spot shortages of commodities, over-stretched sub-contractors and vendors, and
intense competition for craft labor.&nbsp;</p></div><p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"></p>

This determination focuses on identifying which owner or joint venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the entity or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect of requiring the Company to consolidate the entity in which we have a noncontrolling variable interest. Where the Company has determined that it is appropriate to consolidate a VIE which it owns a 50% or less interest, the equity held by the remaining owners and their portions of net income (loss) are reflected in the balance sheet line item &amp;#x201c;Noncontrolling interests&amp;#x201d; in &amp;#x201c;Equity&amp;#x201d; and the statement of operations line item &amp;#x201c;Noncontrolling owners&amp;#x2019; interests in earnings of subsidiaries,&amp;#x201d; unless the equity interest is deemed to be mandatorily redeemable. Refer to Note 2 regarding the Company&amp;#x2019;s mandatorily redeemable obligations.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 13.7pt; margin: 6pt 0"&gt;On August 1, 2011, the Company purchased a 50% limited partner interest in Myers. Myers is a construction limited partnership located in California and was acquired in order to expand the geographic scope of the Company&amp;#x2019;s operations into California. The Company has determined that Myers is a VIE for which the Company is the primary beneficiary and has consolidated Myers into the Company&amp;#x2019;s financial statements.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 13.7pt; margin: 6pt 0"&gt;The determination that Myers is a VIE and that the Company is the primary beneficiary is primarily due to the following factors. The partnership agreement requires that Sterling provide funding as needed, when available, to the limited partnership. In addition, the partnership is relying on the Company&amp;#x2019;s surety bonding capacity in order to bid and perform large construction jobs resulting in the Company having joint and several liability for completion of such jobs, and the Company will provide management to the partnership to oversee bidding and management of larger projects. Although the Company will receive 50% of the income from the partnership, it may suffer more than 50% of any losses as a result of its obligation to provide funding and its obligations under the surety bonds. Because the Company exercises primary control over activities of the partnership and it is exposed to the majority of potential losses of the partnership, the Company consolidated Myers within the Company&amp;#x2019;s financial statements from August 1, 2011, the date of acquisition.&lt;/div&gt;

Due to our new Equipment-based Facility, we have now cash collateralized the letter of credit, resulting in the cash being designated as restricted. Historically, this standby letter of credit has not been drawn upon. Refer to Note 4 for more information on our restricted cash and Note 9 for more information on our new Equipment-based Facility, including the amount held in our standby letter of credit at December 31, 2015 and 2014.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Guarantees&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company obtains bonding on construction contracts through Travelers Casualty and Surety Company of America (&amp;#x201c;Travelers&amp;#x201d;). As is customary in the construction industry, the Company indemnifies Travelers for any losses incurred by it in connection with bonds that are issued. The Company has granted Travelers a security interest in accounts receivable and contract rights for that obligation.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company typically indemnifies contract owners for claims arising during the construction process and carries insurance coverage for such claims, which in the past have not been material.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company&amp;#x2019;s Certificate of Incorporation provides for indemnification of its officers and directors. The Company has a directors and officers insurance policy that limits their exposure to litigation against them in their capacities as such.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Litigation&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company is the subject of certain other claims and lawsuits occurring in the normal course of business. Management, after consultation with legal counsel, does not believe that the outcome of these other actions will have a material impact on the financial statements of the Company. There are no significant unresolved legal issues as of December 31, 2015 and 2014.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Purchase Commitments&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0"&gt;To manage the risk of changes in material prices and subcontracting costs used in tendering bids for construction contracts, most of the time, we obtain firm quotations from suppliers and subcontractors before submitting a bid. These quotations do not include any quantity guarantees. As soon as we are advised that our bid is the lowest, we enter into firm contracts with most of our materials suppliers and sub-contractors, thereby mitigating the risk of future price variations affecting the contract costs.&lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

This determination focuses on identifying which owner or joint venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the entity or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect of requiring the Company to consolidate the entity in which we have a noncontrolling variable interest.

The amount of the Revolving Loan that may be borrowed from time to time is determined quarterly and may not exceed $20.0 million. In addition, the sum of the outstanding balances of the Equipment-based Facility may not exceed the lesser of $40.0 million or 65% of the appraised value of the collateral pledged for the loans. At December 31, 2015, the Company had approximately a borrowing base of $29.6 million, which was the result of calculating 65% of the appraised value (where appraised value equals net operating liquidated value) of the Company&amp;#x2019;s collateral. The Revolving Loan may be utilized by the Company to provide ongoing working capital and for other general corporate purposes.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 64; Value: 1 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Equipment-based Facility bears interest at an initial fixed annual rate of 12%, which is subject to (i) a decrease of up to two percentage points based on the Company's fixed charge coverage ratio for each of the most recently ended four quarters beginning with the four quarters ending June 30, 2016; and (ii) an increase of up to two percentage points beginning December 31, 2015 based on the fixed charge coverage ratio at the end of the following four quarters. Principal on the Term Loan is payable in 47 monthly installments (with accrued interest) with a final payment of the then outstanding principal amount on May 29, 2019. Up to $5.0 million of the Term Loan may be prepaid in any year, but subject to a pre-payment fee that declines as the Term Loan nears maturity. Outstanding Revolving Loans are payable in full thirty days before the maturity date of the Term Loan.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Equipment-based Facility is secured by all of the Company's personal property except accounts receivable, including all of its construction equipment, which forms the basis of availability under the Revolving Loan. The Equipment-based Facility is also secured by one-half of the equipment of the Company's 50%-owned affiliates, Road and Highway Builders, LLC and Myers &amp;amp; Sons Construction, L.P. pursuant to a separate security agreement with those entities. If a default occurs, Nations may exercise the Company's rights in the collateral, with all of the rights of a secured party under the Uniform Commercial Code, including, among other things, the right to sell the collateral at public or private sale.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The proceeds of the Term Loan of $20.0 million and our initial draw of $14.6 million under the Revolving Loan were utilized by the Company to repay the balance outstanding and terminate the Prior Credit Facility and for other general corporate purposes.

Joint venture partners typically provide independently prepared estimates, furnish employees and equipment, enhance bonding capacity and often also bring local knowledge and expertise. We select our joint venture partners based on our analysis of their construction and financial capabilities, expertise in the type of work to be performed and past working relationships with us, among other criteria.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;We participate in various construction joint venture partnerships. Generally, each construction joint venture is formed to accomplish a specific project and is jointly controlled by the joint venture partners. The joint venture agreements typically provide that our interests in any profits and assets, and our respective share in any losses and liabilities that may result from the performance of the contract are limited to our stated percentage interest in the venture. We have no significant commitments beyond completion of the contract with the customer.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Joint venture contracts with project owners typically impose joint and several liability on the joint venture partners. Although our agreements with our joint venture partners provide that each party will assume and pay its share of any losses resulting from a project, if one of our partners is unable to pay its share, we would be fully liable under our contract with the project owner. Circumstances that could lead to a loss under these guarantee arrangements include a partner&amp;#x2019;s inability to contribute additional funds to the venture in the event that the project incurs a loss or additional costs that we could incur should the partner fail to provide the services and resources toward project completion that had been committed to in the joint venture agreement. Historically, the Company has not incurred a liability related to the nonperformance of a joint venture partner.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Under a joint venture agreement, one partner is typically designated as the sponsor or manager. The sponsoring partner typically provides all administrative, accounting and most of the project management support for the project and generally receives a fee from the joint venture for these services. We have been designated as the sponsoring partner in certain of our current joint venture projects and are a non-sponsoring partner in others.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Under GAAP, the Company must determine whether each joint venture in which it participates is a variable interest entity. This determination focuses on identifying which joint venture partner, if any, has the power to direct the activities of a joint venture and the obligation to absorb losses of the joint venture or the right to receive benefits from the joint venture in excess of their ownership interests and could have the effect of requiring us to consolidate joint ventures in which we have a noncontrolling variable interest. At December 31, 2015, we had no participation in a joint venture where we had a material non-majority variable interest.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 62; Value: 1 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Where we are a noncontrolling venture partner, we account for our share of the operations of such construction joint ventures on a pro rata basis using proportionate consolidation on our consolidated statements of operations and as a single line item (&amp;#x201c;Receivables from and equity in construction joint ventures&amp;#x201d;) in the consolidated balance sheets. This method is an acceptable modification of the equity method of accounting which is a common practice in the construction industry.

The Company&amp;#x2019;s financial instruments are cash and cash equivalents, restricted cash used as collateral for a letter of credit and restricted cash maintained in an escrow account, short-term and long-term contracts receivable, derivatives, accounts payable, mortgage and notes payable, a revolving loan (the &amp;#x201c;Revolving Loan&amp;#x201d;) with Nations Fund I, LLC and Nations Equipment Finance, LLC, as administrative agent and collateral agent for the lender (&amp;#x201c;Nations&amp;#x201d;), a tern loan (the &amp;#x2018;Term Loan&amp;#x201d;) with Nations (combined, the &amp;#x201c;Equipment-based facility&amp;#x201d;), and an earn-out liability related to the acquisition of JBC.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The recorded values of cash and cash equivalents, restricted cash, short-term contracts receivable and accounts payable approximate their fair values based on their liquidity and/or short-term nature. The recorded value of the long-term contract receivable was based on the amount of future cash flows discounted using the creditor&amp;#x2019;s borrowing rate and such recorded value approximated fair value.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company provides credit in the normal course of business, principally to public (government) owners, and performs ongoing credit evaluations, as deemed necessary, but generally does not require collateral to support such receivables.&amp;nbsp; In an effort to reduce its credit exposure, as well as accelerate its cash flows, in August 2015, the Company completed the sale, on a non-recourse basis, of its only long-term contract receivable pursuant to a factoring agreement with a related party. The Company received approximately $7.1&amp;nbsp;million upon the closing of this transaction and recorded a loss of approximately $1.4 million in &amp;#x201c;Other operating (expense) income, net.&amp;#x201d;&amp;nbsp; As such, we did not have a long-term contract receivable at December 31, 2015. The long-term contract receivable was historically discounted at 4.25% and recorded at fair value. Interest earned related to the long-term contract receivable was $0.2 million, $0.4 million and $0.3 million for the years ended December 31, 2015, 2014 and 2013, respectively.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Refer to Note 9 regarding the fair value of derivatives, Note 2 regarding the fair value of an earn-out liability along with the most current amendments, and Note 11 regarding the fair value of the Revolving Loan and the Term Loan. The Company also has long-term notes payable of $2.2 million related to machinery and equipment purchased which have payment terms ranging from 3 to 5 years and associated interest rates ranging from 3.12% to 6.29%. The fair value of these notes payable approximates their book value. The Company does not have any off-balance sheet financial instruments other than operating leases (Refer to Note 14).&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In order to assess the fair value of the Company&amp;#x2019;s financial instruments, the Company uses the fair value hierarchy established by GAAP which prioritizes the inputs used in valuation techniques into the following three levels:&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt 0.25in"&gt;Level 1 Inputs &amp;#x2013; Based upon quoted prices for identical assets in active markets that the Company has the ability to access at the measurement date.&lt;div style="display: inline; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt 0.25in"&gt;Level 2 Inputs &amp;#x2013; Based upon quoted prices (other than Level 1) in active markets for similar assets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset such as interest rates, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.&lt;div style="display: inline; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt 0.25in"&gt;Level 3 Inputs &amp;#x2013; Based on unobservable inputs reflecting the Company&amp;#x2019;s own assumptions about the assumptions that market participants would use in pricing the asset based on the best information available.&lt;div style="display: inline; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;For each financial instrument, the Company uses the highest priority level input that is available in order to appropriately value that particular instrument. In certain instances, Level 1 inputs are not available and the Company must use Level 2 or Level 3 inputs. In these cases, the Company provides a description of the valuation techniques used and the inputs used in the fair value measurement.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:FairValueOfFinancialInstrumentsPolicy>

There are two steps involved in the testing of goodwill, excluding a qualitative analysis. The first step compares the book value of the Company&amp;#x2019;s stock (stockholders&amp;#x2019; equity or net assets) to the adjusted fair market value of those shares. If the adjusted fair value of the stock is greater than the calculated book value of the stock, goodwill is deemed not to be impaired and no further testing is required. If the adjusted fair value is less than the calculated book value, then step two of determining the fair value of net assets must be taken to determine the impairment amount.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;To determine the fair value of the Company&amp;#x2019;s net assets, the Company used the weighted average of the following valuation techniques: the market approach, which uses market capitalization information plus a control premium and an income approach, which uses a discounted cash flow methodology. The market approach includes level one fair value inputs, such as the Company&amp;#x2019;s stock price, at the date of our test, and level two fair value inputs, such as the control premiums based on prior year sales transactions of construction contractors and engineering services, similar sized transactions based on the Company&amp;#x2019;s market capitalization, and all-inclusive total industries transactions. The income approach includes level three inputs such as the Company&amp;#x2019;s calculated weighted average cost of capital and future income projections that include assumptions about revenue and gross profit growth, along with other assumptions.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;During the first and third quarters of 2015, the Company noted there was an impairment trigger present during these interim periods and performed step one of the impairment test discussed above. Based on the results of our goodwill impairment tests, we concluded that there was not an impairment of goodwill during these periods. In addition, as part of our 2015 and 2014 annual tests, we determined that the fair value of the Company&amp;#x2019;s equity continues to be more than the carrying value of the Company&amp;#x2019;s equity by approximately 21% and 19%, respectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;At December 31, 2015, we had goodwill with a remaining carrying amount of approximately $54.8 million. Testing under step one in 2014 and 2013 also did not indicate that the adjusted fair value of the Company&amp;#x2019;s stock was less than its book value.&lt;/div&gt;&lt;/div&gt;</us-gaap:GoodwillDisclosureTextBlock>

There was an immaterial impairment in 2015 related to assets held for sale, and no impairment in 2014 and 2013, and management believes that there are no additional events or changes in circumstances which have indicated that other long-lived assets may be impaired.

text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended December 31, 2015. The cumulative three-year period loss that remained at December 31, 2015 was the result of write-downs recorded during the past three years. Such objective evidence limits the ability to consider other subjective evidence such as our projections for future growth. On the basis of this evaluation, as of December 31, 2015, a valuation allowance of $56.4 million has been recorded on the net deferred tax assets including federal and state net operating losses as they are not likely to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted in the future if objective negative evidence or cumulative losses are no longer present and additional weight may be given to subjective evidence such as our projections for growth.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;If our assumptions change and we determine we will be able to realize these deferred tax assets, the tax benefits relating to any reversal of the valuation allowance on deferred tax assets as of December 31, 2015, will be accounted for as follows: approximately $46.8 million will be recognized as a reduction of income tax expense and $9.6 million will be recorded as an increase in equity.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;On September 13, 2013, the U.S. Treasury Department and the I.R.S. issued final regulations that address costs incurred in acquiring, producing, or improving tangible property (the &amp;quot;tangible property regulations&amp;quot;). The tangible property regulations are generally effective for tax years beginning on or after January 1, 2014. The Company intends to adopt the tax treatment of expenditures to improve tangible property and the capitalization of inherently facilitative costs to acquire tangible property as of January 1, 2014. The tangible property regulations will require the Company to make additional tax accounting method changes as of January 1, 2014; however, management does not anticipate the impact of these changes to be material to the Company&amp;#x2019;s consolidated financial position, its results of operations, or both.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;As a result of the Company&amp;#x2019;s analysis, management has determined that the Company does not have any material uncertain tax positions. The Company&amp;#x2019;s policy is to recognize interest related to any underpayment of taxes as interest expense, and penalties as administrative expenses. No interest or penalties have been accrued at December 31, 2015 or 2014. The Company&amp;#x2019;s U.S. federal income tax returns for 2012 and later years are open and subject to examination by the I.R.S. In addition, the Company&amp;#x2019;s state income tax returns for 2011 and later years are open and subject to examination.&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. Refer to Note 12 for further information regarding our federal and state income taxes.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxPolicyTextBlock>

Under this method of accounting, the recorded value of the leased asset is amortized principally using the straight-line method over its estimated useful life and the obligation, including interest thereon, is reduced through payments over the life of the lease. Depreciation expense on equipment subject to capital leases and the related accumulated depreciation is included with that of owned equipment. The Company had one capital lease at December 31, 2015 of $0.5 million recorded in &amp;#x201c;Long-term debt, net of current maturities&amp;#x201d; and &amp;#x201c;Current maturities of long-term debt,&amp;#x201d; as applicable, in our consolidated balance sheet and had no capital leases during the years ended December 31, 2014 and 2013.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:LeasePolicyTextBlock>

The Third Amended and Restated Operating Agreement and the amended Management Agreement eliminated the buy/sell option and instead included the obligation for the Company to purchase Mr. Buenting&amp;#x2019;s interest upon his death or permanent disability for $20 million or $18 million (subsequently increased to $20 million), respectively. In the event of Mr. Buenting&amp;#x2019;s death or permanent disability, his estate representative, trustee or designee shall become the selling representative and sell his 50% interest to the Company. In order to fund the purchase of Mr. Buenting&amp;#x2019;s interest, the Company has purchased term life insurance with a payout of $20 million in the event of Mr. Buenting&amp;#x2019;s death. The Company will be the beneficiary and will also pay the premiums related to this life insurance contract. The life insurance proceeds of $20 million shall be used as full payment for Mr. Buenting&amp;#x2019;s interest in the occurrence of his death. On June 2, 2015, the Company purchased an insurance policy with a five-year term on Mr. Buenting that provides a lump sum disability benefit in the principal sum of $20 million. &amp;nbsp;In the event of Mr. Buenting&amp;#x2019;s permanent total disability, the principal sum becomes payable to the Company, and in turn the Company is obligated to use the proceeds of the policy to purchase Mr. Buenting&amp;#x2019;s 50% member&amp;#x2019;s interest in RHB in accordance with the terms of the amended agreements. No other transfer of member&amp;#x2019;s interest is permitted other than to the selling representative in the event of Mr. Buenting&amp;#x2019;s death or permanent disability. The amended agreements were entered into in order to eliminate the earnings-per-share volatility caused by the buy/sell option.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 57; Value: 1 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The amended agreements resulted in an obligation to purchase Mr. Buenting&amp;#x2019;s 50% member&amp;#x2019;s interest that the Company is certain to incur because of Mr. Buenting&amp;#x2019;s death; therefore, the Company has classified the noncontrolling interest as mandatorily redeemable and has recorded a liability in &amp;#x201c;Members&amp;#x2019; interest subject to mandatory redemption and undistributed earnings&amp;#x201d; on the consolidated balance sheets.

According to GAAP, this reduction to APIC is treated similarly to a dividend to a preferred shareholder, and would reduce earnings per share. Therefore, this $18.8 million reduction in APIC was included as a reduction to earnings per share attributable to Sterling common stockholders.

The purchase price and the accounting effects of the total transaction were immaterial to the Company.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 5pt 0 2pt"&gt;&lt;div style="display: inline; font-style: italic;"&gt;JBC&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;On January 23, 2014, RLW, the former owner of JBC and the Company agreed to amend the above mentioned earn-out agreement in order to reduce the Company&amp;#x2019;s recorded liability at that time, while providing the former owner, who at the time was the chief executive officer of JBC, a greater incentive to meet earnings benchmarks. The amendment resulted in a reduction of $0.6 million in the Company&amp;#x2019;s earn-out liability, thereby reducing the total earn-out liability to $1.4 million on December 31, 2013. As part of the amendment, a payment of $0.8 million was made during the first quarter of 2014. The amendment increased the total available earn-out from $5.0 million to $10.0 million if certain EBITDA benchmarks are met. The amendment extended the earn-out period through December 31, 2017 and reduced the benchmark EBITDA for 2014 and 2015 to $1.5 million and increased it to $2.0 million in 2016 and 2017. This earn-out liability continues to be classified as a Level 3 fair value measurement and the unobservable inputs continue to be the forecasted EBITDA for the periods after the period being reported on through December 31, 2017. There was no yearly excess forecasted EBITDA in our calculation at December 31, 2015 of the minimum EBITDA benchmarks for the years 2016 through 2017. The discounted present value of the additional purchase price was estimated to be $0.3 million as of December 31, 2014. The undiscounted earn-out liability as of December 31, 2015 is minimal and could increase by $9.3 million if EBITDA during the earn-out period increases $18.5 million or more and could decrease by the full amount of the liability for the year if EBITDA does not exceed the minimum threshold for that year. Each year is considered a discrete earnings period and future losses by JBC, if any, would not reduce the Company&amp;#x2019;s liability in years in which JBC has exceeded its earnings benchmark. Any significant increase or decrease in actual EBITDA compared to the forecasted amounts would result in a significantly higher or lower fair value measurement of the additional purchase price. This liability is included in other long-term liabilities on the accompanying consolidated balance sheets. As part of recording the present value of this liability, the Company incurs accreted interest expense for the passage of time until the time of settlement. The Company incurred accreted interest expense of $0.3 million for the year ended December 31, 2014. As part of the updated EBITDA forecast, the Company reduced its liability to zero and recorded interest income of $0.3 million in the first quarter of 2015. There has been minimal change in the value of this liability; therefore, the interest income was $0.3 million for the year ended December 31, 2015.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Noncontrolling Interests&amp;#x2019; &amp;#x2013; Call Options&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;During the year ended December 31, 2015, the Company entered into several agreements, with RHB and with Myers, which gives the 50% owners of these entities the option to buy the Company&amp;#x2019;s 50% interest in these entities for $10,000 should the Company ever become subject to the repossession or disposition of its collateral as defined in the Company&amp;#x2019;s new debt agreement with Nations or if the Company dissolves or becomes insolvent. Based on these agreements, the Company does not believe that it is likely that the exercise of these options would ever transpire; therefore, there has been no value placed on these options which resulted in no impact to our consolidated financial statements. Refer to Note 9 for more information about the debt agreement with Nations.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline;

The update is effective for public business entities issuing financial statements for the annual periods beginning after December 15, 2015, and interim periods within those annual periods. The Company retrospectively adopted the provisions of this ASU at December 31, 2015. Accordingly, $1.2 million of net deferred tax assets have been reclassified from current to non-current in the accompanying consolidated balance sheet as of December 31, 2014. The net deferred tax assets include an offsetting valuation allowance; therefore, there was no change to the consolidated balance sheet as of December 31. Refer to Note 12.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In August 2015, FASB issued ASU 2015-15, &amp;#x201c;Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.&amp;#x201d; The guidance, which incorporates the SEC Staff Announcement at the June 18, 2015 EITF meeting and is effective upon announcement, provides clarification related to the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. The guidance states that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company is currently accounting for its debt issuance costs for its Term Loan and line-of-credit Revolver Loan in this manner and would only expect a change in presentation of the deferred amounts related to the Term Loan upon adoption as required by ASU 2015-03. See below for the discussion related to ASU 2015-03.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In July 2015, the FASB issued ASU 2015-11, &amp;#x201c;Inventory (Topic 330): Simplifying the Measurement of Inventory.&amp;#x201d; The guidance, which is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those fiscal years, requires an entity to measure in scope inventory at the lower of cost and net realizable value. Early adoption is permitted as of the beginning of an interim or annual reporting period. Although early adoption is permitted, the Company expects to adopt this guidance as required and does not expect a material impact to the Company&amp;#x2019;s consolidated financial statements.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In April 2015, the FASB issued ASU 2015-03, &amp;#x201c;Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.&amp;#x201d; The guidance, which is effective for annual reporting periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015, requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The adoption of this ASU requires retrospective application to all periods presented. Although early adoption is permitted, the Company expects to adopt this guidance as required and expects a change in the presentation of our consolidated balance sheets and related disclosures. The Company does not expect a material impact to the consolidated statements of operations.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In February 2015, the FASB issued ASU 2015-02, &amp;#x201c;Consolidation: Amendments to the Consolidation Analysis.&amp;#x201d; The guidance, which is effective for annual reporting periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015, modifies the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. Early adoption is permitted. The Company does not expect a material impact to the Company&amp;#x2019;s consolidated financial statements and related disclosures.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In August 2014, the Financial Accounting Standards Board (&amp;#x201c;FASB&amp;#x201d;) issued ASU 2014-14, &amp;#x201c;Presentation of Financial Statement &amp;#x2013; Going Concern.&amp;#x201d; The guidance, which is effective for annual reporting periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016, requires management to evaluate whether there is substantial doubt about the entity&amp;#x2019;s ability to continue as a going concern and to provide related footnote disclosures. Early adoption is permitted. Although early adoption is permitted, the Company expects to adopt this guidance as required and does not expect a material impact to our financial statements.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In May 2014, the FASB issued ASU 2014-09, &amp;#x201c;Revenue from Contracts with Customers.&amp;#x201d; The guidance defines the steps to recognize revenue for entities that have contracts with customers. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 by one year. As a result, the amendments in ASU 2014-09 are effective for public companies for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Entities would be permitted to adopt this ASU as early as the original public entity effective date, which were annual reporting periods beginning after December 15, 2016 and interim periods therein. Early adoption prior to that date would not be permitted.&amp;nbsp; The Company is currently evaluating the impact of the adoption of this ASU to the Company&amp;#x2019;s consolidated financial statements and related disclosures.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

For investments in subsidiaries and construction joint ventures that are not wholly-owned, but where the Company exercises control, the equity held by the remaining owners and their portions of net income (loss) are reflected in the balance sheet line item &amp;#x201c;Noncontrolling interests&amp;#x201d; in &amp;#x201c;Equity&amp;#x201d; and the statement of operations line item &amp;#x201c;Noncontrolling owners&amp;#x2019; interests in earnings of subsidiaries,&amp;#x201d; respectively. All significant intercompany accounts and transactions have been eliminated in consolidation. For all years presented, the Company had no subsidiaries where its ownership interests were less than 50%.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Where the Company is a noncontrolling joint venture partner, and otherwise not required to consolidate the joint venture entity, its share of the operations of such construction joint venture is accounted for on a pro rata basis in the consolidated statements of operations and as a single line item (&amp;#x201c;Receivables from and equity in construction joint ventures&amp;#x201d;) in the consolidated balance sheets. This method is an acceptable modification of the equity method of accounting which is a common practice in the construction industry. Refer to Note 6&lt;div style="display: inline; color: red"&gt; &lt;/div&gt;for further information regarding the Company&amp;#x2019;s construction joint ventures.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Under accounting principles generally accepted in the United States (&amp;#x201c;GAAP&amp;#x201d;), the Company must determine whether each entity, including joint ventures in which it participates, is a variable interest entity (&amp;#x201c;VIE&amp;#x201d;). This determination focuses on identifying which owner or joint venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the entity or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect of requiring the Company to consolidate the entity in which we have a noncontrolling variable interest. Refer to Note 3 for further information regarding the Company&amp;#x2019;s consolidated VIE.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Use of Estimates&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Certain of the Company&amp;#x2019;s accounting policies require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion method, the valuation of long-term assets (including goodwill), and income taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Revenue Recognition&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company is a general contractor which engages in various types of heavy civil construction projects principally for public (government) owners. Credit risk is minimal with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related costs. Credit risk with private owners is minimized because of statutory mechanics liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners. Refer to Note 16 for further information regarding the Company&amp;#x2019;s concentration of risk.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 51; Value: 1 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Revenues are recognized on the percentage-of-completion method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Changes in estimated revenues and gross margin during the year ended December 31, 2015 resulted in a net charge of $9.7 million included in operating loss, or $0.50 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders. Changes in estimated revenues and gross margin during the year ended December 31, 2014 resulted in a net charge of $9.1 million included in operating loss, or $0.50 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders. Changes in estimated revenues and gross margin during the year ended December 31, 2013 resulted in a net charge of $57.6 million included in operating loss, or $3.46 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Change orders are modifications of an original contract that effectively change the existing provisions of the contract without adding new scope or terms. Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Either we or our customers may initiate change orders.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company considers unapproved change orders to be contract variations for which we have customer approval for a change of scope but a price change associated with the scope change has not yet been agreed upon. Costs associated with unapproved change orders are included in the estimated cost to complete the contracts and are treated as project costs as incurred. The Company recognizes revenue equal to costs incurred on unapproved change orders when realization of price approval is probable. Unapproved change orders involve the use of estimates, and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting periods to reflect changes in estimates or final agreements with customers. Change orders that are unapproved as to both price and scope are evaluated as claims.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company considers claims to be amounts in excess of agreed contract prices that we seek to collect from our customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs. Claims are included in the calculation of revenue when realization is probable and amounts can be reliably determined to the extent costs are incurred. To support these requirements, the existence of the following items must be satisfied: 1. The contract or other evidence provides a legal basis for the claim; or a legal opinion has been obtained, stating that under the circumstances there is a reasonable basis to support the claim; 2. Additional costs are caused by circumstances that were unforeseen at the contract date and are not the result of deficiencies in the contractor&amp;#x2019;s performance; 3. Costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and 4. The evidence supporting the claim is objective and verifiable, not based on management&amp;#x2019;s feel for the situation or on unsupported representations. Revenues in excess of contract costs incurred on claims is recognized when an agreement is reached with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract. Costs associated with claims are included in the estimated costs to complete the contracts and are treated as project costs when incurred.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;There were $1.6 million in costs and estimated earnings in excess of billings at December 31, 2015 and $3.5 million in costs and estimated earnings in excess of billing at December 31, 2014, for contract change orders not approved by the customer. In addition, the Company recorded $5.2 million in revenues related to claims during the year ended December 31, 2015, and did not record revenues related to claims during the years ended December 31, 2014 and 2013.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Our contracts generally take 12 to 36 months to complete. The Company generally provides a one to two-year warranty for workmanship under its contracts when completed. Warranty claims historically have been insignificant.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 52; Value: 1 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The asset, &amp;#x201c;Costs and estimated earnings in excess of billings on uncompleted contracts&amp;#x201d; represents revenues recognized in excess of amounts billed on these contracts and will be billed at a later date, usually due to contract terms.

The Company&amp;#x2019;s financial instruments are cash and cash equivalents, restricted cash used as collateral for a letter of credit and restricted cash maintained in an escrow account, short-term and long-term contracts receivable, accounts payable, notes payable, a revolving loan (the &amp;#x201c;Revolving Loan&amp;#x201d;) with Nations Fund I, LLC and Nations Equipment Finance, LLC, as administrative agent and collateral agent for the lender (&amp;#x201c;Nations&amp;#x201d;), a term loan (the &amp;#x201c;Term Loan&amp;#x201d;) with Nations (combined, the &amp;#x201c;Equipment-based Facility&amp;#x201d;), and an earn-out liability related to the acquisition of JBC.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The recorded values of cash and cash equivalents, restricted cash, short-term contracts receivable and accounts payable approximate their fair values based on their liquidity and/or short-term nature. The recorded value of the long-term contract receivable was based on the amount of future cash flows discounted using the creditor&amp;#x2019;s borrowing rate and such recorded value approximated fair value.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company provides credit in the normal course of business, principally to public (government) owners, and performs ongoing credit evaluations, as deemed necessary, but generally does not require collateral to support such receivables.&amp;nbsp; In an effort to reduce its credit exposure, as well as accelerate its cash flows, in August 2015, the Company completed the sale, on a non-recourse basis, of its only long-term contract receivable pursuant to a factoring agreement with a related party. The Company received approximately $7.1&amp;nbsp;million upon the closing of this transaction and recorded a loss of approximately $1.4 million in &amp;#x201c;Other operating (expense) income, net.&amp;#x201d;&amp;nbsp; As such, we did not have a long-term contract receivable at December 31, 2015.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Refer to Note 2 regarding the fair value of an earn-out liability along with the most current amendments, and Note 9 regarding the fair value of the Revolving Loan and the Term Loan. The Company also has long-term notes payable of $2.2 million related to machinery and equipment purchased which have payment terms ranging from 3 to 5 years and associated interest rates ranging from 3.12% to 6.29%. The fair value of these notes payable approximates their book value. The Company does not have any off-balance sheet financial instruments other than operating leases (Refer to Note 12).&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In order to assess the fair value of the Company&amp;#x2019;s financial instruments, the Company uses the fair value hierarchy established by GAAP which prioritizes the inputs used in valuation techniques into the following three levels:&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt 0.25in"&gt;Level 1 Inputs &amp;#x2013; Based upon quoted prices for identical assets in active markets that the Company has the ability to access at the measurement date.&lt;div style="display: inline; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt 0.25in"&gt;Level 2 Inputs &amp;#x2013; Based upon quoted prices (other than Level 1) in active markets for similar assets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset such as interest rates, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.&lt;div style="display: inline; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt 0.25in"&gt;Level 3 Inputs &amp;#x2013; Based on unobservable inputs reflecting the Company&amp;#x2019;s own assumptions about the assumptions that market participants would use in pricing the asset based on the best information available.&lt;div style="display: inline; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;For each financial instrument, the Company uses the highest priority level input that is available in order to appropriately value that particular instrument. In certain instances, Level 1 inputs are not available and the Company must use Level 2 or Level 3 inputs. In these cases, the Company provides a description of the valuation techniques used and the inputs used in the fair value measurement.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0in; margin: 6pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Contracts Receivable&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Contracts receivable are generally based on amounts billed to the customer. At December 31, 2015 and 2014, contracts receivable included $19.8 million and $16.4 million of retainage, respectively, discussed below, which is being withheld by customers until completion of the contracts, and at December 31, 2015, and 2014, there were no unbilled receivables on contracts completed or substantially complete at that date. All contracts receivable include only balances approved for payment by the customer.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 53; Value: 1 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Many of the contracts under which the Company performs work contain retainage provisions. Retainage refers to that portion of billings made by the Company but held for payment by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained by customers under such provisions are fully collectible. Retainage on active contracts is classified as a current asset regardless of the term of the contract and is generally collected within one year of the completion of a contract.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;There are certain contracts that are completed in advance of full payment. When the receivable will not be collected within our normal operating cycle, we consider it a long-term contract receivable and it is recorded in &amp;#x201c;Other assets, net&amp;#x201d; in our balance sheet. In August 2015, the Company completed the sale, on a non-recourse basis, of its only long-term contract receivable pursuant to a factoring agreement with a related party. As such, there was no outstanding long-term contract receivable at December 31, 2015. At December 31, 2014, there was $5.0 million recorded. We considered the credit quality of the borrower to assess the appropriate discount rate applied and continuously monitored the borrower&amp;#x2019;s credit quality. The long-term contract receivable was historically discounted at 4.25% and recorded at fair value. Interest income related to this receivable was $0.2 million, $0.4 million and $0.3 million for the years ended December 31, 2015, 2014 and 2013, respectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Contracts receivable are written off based on individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. There was an immaterial amount of bad debt expense recorded in 2015 and no bad debt expense recorded in 2014. In 2013, the Company wrote off $1.8 million of contracts receivable to bad debt expense which was recorded in &amp;#x201c;Other operating (expense) income, net.&amp;#x201d; During 2014, we recovered $1.0 million of this $1.8 million.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;At year-end, the Company performs a review of outstanding contracts receivable, historical collection information and existing economic conditions to determine if there are potential uncollectible receivables. At December 31, 2015 and 2014, our allowance for doubtful accounts against contracts receivable was immaterial and zero, respectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;As is customary, we have agreed to indemnify our bonding company for all losses incurred by it in connection with bonds that are issued, and we have granted our bonding company a security interest in certain assets, including accounts receivable, as collateral for such obligation.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Inventories&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company&amp;#x2019;s inventories are stated at the lower of cost or market as determined by the average cost method. Inventories at December 31, 2015 and 2014 were $2.5 million and $7.4 million, respectively. Inventories consist primarily of concrete, aggregate and millings which are primarily expected to be utilized on construction projects in the future. A small portion is sold to third parties.

Our leases have varying terms. Some may include renewal options, escalation clauses, restrictions, penalties or other obligations that we consider in determining minimum lease payments. The leases are classified as either operating leases or capital leases, as appropriate.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Equipment under Capital Leases&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company&amp;#x2019;s policy is to account for capital leases, which transfer substantially all the benefits and risks incident to the ownership of the leased property to the Company, as the acquisition of an asset and the incurrence of an obligation. Under this method of accounting, the recorded value of the leased asset is amortized principally using the straight-line method over its estimated useful life and the obligation, including interest thereon, is reduced through payments over the life of the lease. Depreciation expense on equipment subject to capital leases and the related accumulated depreciation is included with that of owned equipment. The Company had one capital lease at December 31, 2015 of $0.5 million recorded in &amp;#x201c;Long-term debt, net of current maturities&amp;#x201d; and &amp;#x201c;Current maturities of long-term debt,&amp;#x201d; as applicable, in our consolidated balance sheet and had no capital leases during the years ended December 31, 2014 and 2013.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 54; Value: 1 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Deferred Loan Costs&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Deferred loan costs represent loan origination fees paid to the lender and related professional fees such as legal fees related to drafting of loan agreements. During 2015, the Company capitalized an additional $1.3 million in loan fees paid to Nations in connection with incurring the new debt, discussed further in Note 9. These capitalized fees are amortized on a straight-line basis over the term of the Equipment-based Facility. Unamortized costs were $1.1 million and $0.2 million at December 31, 2015 and 2014 and are attributable to the Equipment-based Facility and Prior Credit Facility, respectively (Refer to Note 9). Loan cost amortization expense for the years ended December 31, 2015, 2014, and 2013 was $0.3 million, $0.2 million, and $0.1 million, respectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-indent: 0in; margin: 6pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Goodwill and Intangibles&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Goodwill represents the excess of the cost of companies acquired over the fair value of their net assets at the dates of acquisition. GAAP requires that: (1) goodwill and indefinite lived intangible assets not be amortized, (2) goodwill is to be tested for impairment at least annually at the reporting unit level and (3) intangible assets deemed to have an indefinite life are to be tested for impairment at least annually by comparing the fair value of these assets with their recorded amounts.

The evaluation would be based on estimated undiscounted cash flows associated with the assets as compared to the asset&amp;#x2019;s carrying amount to determine if a write-down to fair value is required. There was an immaterial impairment in 2015 related to assets held for sale, and no impairment in 2014 and 2013, and management believes that there are no additional events or changes in circumstances which have indicated that other long-lived assets may be impaired.

In making this determination, the Company considered the discrete financial information used by our Chief Operating Decision Maker (&amp;#x201c;CODM&amp;#x201d;). Based on this approach, the Company noted that the CODM organizes, evaluates and manages the financial information around each heavy civil construction project when making operating decisions and assessing the Company&amp;#x2019;s overall performance. The service provided by the Company, in all instances of our construction projects, is heavy civil construction. Furthermore, we considered that each heavy civil construction project has similar characteristics, includes similar services, has similar types of customers and is subject to similar economic and regulatory environments which would allow aggregation of individual operating segments into one reportable segment if multiple operating segments existed.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company noted that even if our local offices were to be considered separate components of our heavy civil construction operating segment, those components could be aggregated into a single reporting unit for purposes of testing goodwill for impairment under Accounting Standards Codification 280 and EITF D-101 because our local offices all have similar economic characteristics and are similar in all of the following areas:&lt;/div&gt;  &lt;table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;"&gt;       &lt;tr style="vertical-align: top"&gt;     &lt;td style="width: 0.25in"&gt;&lt;/td&gt;     &lt;td style="width: 0.25in"&gt;&lt;div style="display: inline; font-family: Symbol"&gt;&amp;middot;&lt;/div&gt;&lt;/td&gt;     &lt;td style="text-align: justify"&gt;The nature of the products and services &amp;#x2014; each of our local offices perform similar construction projects &amp;#x2014; they build, reconstruct and repair roads, highways, bridges, airfields, ports, light rail and water, waste water and storm drainage systems.&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;  &lt;table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;"&gt;       &lt;tr style="vertical-align: top"&gt;     &lt;td style="width: 0.25in"&gt;&lt;/td&gt;     &lt;td style="width: 0.25in"&gt;&lt;div style="display: inline; font-family: Symbol"&gt;&amp;middot;&lt;/div&gt;&lt;/td&gt;     &lt;td style="text-align: justify"&gt;The nature of the production processes &amp;#x2014; our heavy civil construction services rendered in the construction process for each of our construction projects performed by each local office is the same &amp;#x2014; they excavate dirt, remove existing pavement and pipe, lay aggregate or concrete pavement, pipe and rail and build bridges and similar large structures in order to complete our projects.&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;  &lt;table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;"&gt;       &lt;tr style="vertical-align: top"&gt;     &lt;td style="width: 0.25in"&gt;&lt;/td&gt;     &lt;td style="width: 0.25in"&gt;&lt;div style="display: inline; font-family: Symbol"&gt;&amp;middot;&lt;/div&gt;&lt;/td&gt;     &lt;td style="text-align: justify"&gt;The type or class of customer for products and services &amp;#x2014; substantially all of our customers are federal and state departments of transportation, cities, counties, and regional water, rail and toll-road authorities.

Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

The Compensation Committee may reward employees and non-employees with various types of awards including, but not limited to, warrants, stock options, common stock, and unvested common stock (or restricted stock) vesting on service, performance or market criteria. The Company recognizes expense based on the grant-date fair value of the service award and amortizes the award based on accelerated or straight line methods. Awards based on performance vesting are subsequently remeasured at each reporting date through the settlement date. Awards that vest based on market criteria are valued using a valuation model that incorporates the probability of the Company meeting the stated criteria, such as the Monte-Carlo simulation, and the expense is amortized on a straight line basis over the term of the agreement.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0"&gt;Upon the vesting of unvested common stock the Company may withhold shares, based on the employee&amp;#x2019;s election, in order to satisfy federal tax withholdings. The shares held by the Company are considered constructively retired and are retired shortly after withholding. The Company then remits the withholding taxes required.

Entities would be permitted to adopt this ASU as early as the original public entity effective date, which were annual reporting periods beginning after December 15, 2016 and interim periods therein. Early adoption prior to that date would not be permitted.&amp;nbsp; The Company is currently evaluating the impact of the adoption of this ASU to the Company&amp;#x2019;s consolidated financial statements and related disclosures.&lt;/div&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

Our second and third quarter revenues and results of operations typically reflect these seasonal trends.

Gross profit was depressed by downward revisions of gross profit on problem projects, the majority of which are being constructed in Texas, primarily due to spot shortages of commodities, over-stretched sub-contractors and vendors, and intense competition for craft labor.&amp;nbsp;&lt;/div&gt;&lt;/div&gt;</us-gaap:QuarterlyFinancialInformationTextBlock>

At December 31, 2015 and 2014, contracts receivable included $19.8 million and $16.4 million of retainage, respectively, discussed below, which is being withheld by customers until completion of the contracts, and at December 31, 2015, and 2014, there were no unbilled receivables on contracts completed or substantially complete at that date. All contracts receivable include only balances approved for payment by the customer.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Many of the contracts under which the Company performs work contain retainage provisions. Retainage refers to that portion of billings made by the Company but held for payment by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained by customers under such provisions are fully collectible. Retainage on active contracts is classified as a current asset regardless of the term of the contract and is generally collected within one year of the completion of a contract.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;There are certain contracts that are completed in advance of full payment. When the receivable will not be collected within our normal operating cycle, we consider it a long-term contract receivable and it is recorded in &amp;#x201c;Other assets, net&amp;#x201d; in our balance sheet. In August 2015, the Company completed the sale, on a non-recourse basis, of its only long-term contract receivable pursuant to a factoring agreement with a related party. As such, there was no outstanding long-term contract receivable at December 31, 2015. At December 31, 2014, there was $5.0 million recorded. We considered the credit quality of the borrower to assess the appropriate discount rate applied and continuously monitored the borrower&amp;#x2019;s credit quality. Interest income related to this receivable was $0.2 million, $0.4 million and $0.3 million for the years ended December 31, 2015, 2014 and 2013, respectively.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Contracts receivable are written off based on individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. There was an immaterial bad debt expense recorded in 2015 and no bad debt expense recorded in 2014. In 2013, the Company wrote off $1.8 million of contracts receivable to bad debt expense which was recorded in &amp;#x201c;Other operating (expense) income, net.&amp;#x201d; During 2014, we recovered $1.0 million of this $1.8 million.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Based upon a review of outstanding contracts receivable, historical collection information and existing economic conditions, management has determined that substantially all contracts receivable at December 31, 2015 are fully collectible, and accordingly, an immaterial allowance for doubtful accounts against contracts receivable was recorded.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;As is customary, we have agreed to indemnify our bonding company for all losses incurred by it in connection with bonds that are issued, and we have granted our bonding company a security interest in certain assets, including accounts receivable, as collateral for such obligation.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:ReceivablesPolicyTextBlock>

RLW leases its main office and equipment maintenance shop for its Utah operations for an annual cost of approximately $0.5 million. The office and shop leases expire in 2022.

Credit risk is minimal with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related costs. Credit risk with private owners is minimized because of statutory mechanics liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners. Refer to Note 18 for further information regarding the Company&amp;#x2019;s concentration of risk.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Revenues are recognized on the percentage-of-completion method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Changes in estimated revenues and gross margin during the year ended December 31, 2015 resulted in a net charge of $9.6 million included in operating loss, or $0.50 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders.

Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Either we or our customers may initiate change orders.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company considers unapproved change orders to be contract variations for which we have customer approval for a change of scope but a price change associated with the scope change has not yet been agreed upon. Costs associated with unapproved change orders are included in the estimated cost to complete the contracts and are treated as project costs as incurred. The Company recognizes revenue equal to costs incurred on unapproved change orders when realization of price approval is probable. Unapproved change orders involve the use of estimates, and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting periods to reflect changes in estimates or final agreements with customers. Change orders that are unapproved as to both price and scope are evaluated as claims.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company considers claims to be amounts in excess of agreed contract prices that we seek to collect from our customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs. Claims are included in the calculation of revenue when realization is probable and amounts can be reliably determined. To support these requirements, the existence of the following items must be satisfied: 1. The contract or other evidence provides a legal basis for the claim; or a legal opinion has been obtained, stating that under the circumstances there is a reasonable basis to support the claim; 2. Additional costs are caused by circumstances that were unforeseen at the contract date and are not the result of deficiencies in the contractor&amp;#x2019;s performance; 3. Costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and 4. The evidence supporting the claim is objective and verifiable, not based on management&amp;#x2019;s feel for the situation or on unsupported representations. Revenue in excess of contract costs incurred on claims is recognized when an agreement is reached with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract. Costs associated with claims are included in the estimated costs to complete the contracts and are treated as project costs when incurred.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;There &lt;div style="display: inline; background-color: yellow"&gt;was $3.5 million&lt;/div&gt; in costs and estimated earnings in excess of billings at December 31, 2015 and $3.5 million in costs and estimated earnings in excess of billing at December 31, 2014, for contract change orders not approved by the customer. In addition, the Company recorded &lt;div style="display: inline; background-color: yellow"&gt;$xx million&lt;/div&gt; in revenues related to claims during the year ended December 31, 2015, and did not record revenues related to claims during the years ended December 31, 2014 and 2013.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Our contracts generally take 12 to 36 months to complete. The Company generally provides a one to two-year warranty for workmanship under its contracts when completed.

In making this determination, the Company considered the discrete financial information used by our Chief Operating Decision Maker (&amp;#x201c;CODM&amp;#x201d;). Based on this approach, the Company noted that the CODM organizes, evaluates and manages the financial information around each heavy civil construction project when making operating decisions and assessing the Company&amp;#x2019;s overall performance. The service provided by the Company, in all instances of our construction projects, is heavy civil construction. Furthermore, we considered that each heavy civil construction project has similar characteristics, includes similar services, has similar types of customers and is subject to similar economic and regulatory environments which would allow aggregation of individual operating segments into one reportable segment if multiple operating segments existed.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company noted that even if our local offices were to be considered separate components of our heavy civil construction operating segment, those components could be aggregated into a single reporting unit for purposes of testing goodwill for impairment under Accounting Standards Codification 280 and EITF D-101 because our local offices all have similar economic characteristics and are similar in all of the following areas:&lt;/div&gt;&lt;table style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;" cellpadding="0" cellspacing="0"&gt; &lt;tr style="vertical-align: top"&gt; &lt;td style="width: 0.25in"&gt;&lt;/td&gt; &lt;td style="width: 0.25in"&gt;&lt;div style="display: inline; font-family: Symbol"&gt;&amp;middot;&lt;/div&gt;&lt;/td&gt; &lt;td style="text-align: justify"&gt;The nature of the products and services &amp;#x2014; each of our local offices perform similar construction projects &amp;#x2014; they build, reconstruct and repair roads, highways, bridges, airfields, light rail and water, waste water and storm drainage systems.&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;table style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;" cellpadding="0" cellspacing="0"&gt; &lt;tr style="vertical-align: top"&gt; &lt;td style="width: 0.25in"&gt;&lt;/td&gt; &lt;td style="width: 0.25in"&gt;&lt;div style="display: inline; font-family: Symbol"&gt;&amp;middot;&lt;/div&gt;&lt;/td&gt; &lt;td style="text-align: justify"&gt;The nature of the production processes &amp;#x2014; our heavy civil construction services rendered in the construction process for each of our construction projects performed by each local office is the same &amp;#x2014; they excavate dirt, remove existing pavement and pipe, lay aggregate or concrete pavement, pipe and rail and build bridges and similar large structures in order to complete our projects.&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;table style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;" cellpadding="0" cellspacing="0"&gt; &lt;tr style="vertical-align: top"&gt; &lt;td style="width: 0.25in"&gt;&lt;/td&gt; &lt;td style="width: 0.25in"&gt;&lt;div style="display: inline; font-family: Symbol"&gt;&amp;middot;&lt;/div&gt;&lt;/td&gt; &lt;td style="text-align: justify"&gt;The type or class of customer for products and services &amp;#x2014; substantially all of our customers are federal and state departments of transportation, cities, counties, and regional water, rail and toll-road authorities.

The Compensation Committee may reward employees and non-employees with various types of awards including, but not limited to, warrants, stock options, common stock, and unvested common stock (or restricted stock) vesting on service or performance criteria. The Company recognizes expense based on the grant-date fair value of the award and amortizes the award based on accelerated or straight line methods. Awards based on performance vesting are subsequently remeasured at each reporting date through the settlement date.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0"&gt;Upon the vesting of unvested common stock the Company may withhold shares, based on the employee&amp;#x2019;s election, in order to satisfy federal tax withholdings. The shares held by the Company are considered constructively retired and are retired shortly after withholding. The Company then remits the withholding taxes required. Refer to Note 16 for further information regarding the stock-based incentive plans.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

Subject to the rights of holders of any then outstanding shares of preferred stock, common stockholders are entitled to receive ratably any dividends that may be declared by the Board of Directors out of funds legally available for that purpose. Holders of common stock are entitled to share ratably in net assets upon any dissolution or liquidation after payment of provision for all liabilities and any preferential liquidation rights of our preferred stock then outstanding. Common stock shares are not subject to any redemption provisions and are not convertible into any other shares of capital stock. The rights, preferences and privileges of holders of common stock are subject to those of the holders of any shares of preferred stock that may be issued in the future.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Board of Directors may authorize the issuance of one or more classes or series of preferred stock without stockholder approval and may establish the voting powers, designations, preferences and rights and restrictions of such shares. No preferred shares have been issued.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Treasury and Forfeited Shares&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In October 2008, the Company announced a share-repurchase program to purchase up to $5 million in shares of common stock. In August 2010, the Company announced an increase to the share-repurchase program to purchase an additional $5 million in shares of common stock, for a total up to $10 million. The specific timing and amount of repurchase will vary based on market conditions, securities law limitations and other factors. There were no shares repurchases in 2015 and 2014 related to the share-repurchase program.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company accounts for the repurchase of treasury shares under the cost method. When shares are repurchased, cash is paid and the treasury stock account is debited for the price paid. Under the cost method, retirement of treasury stock would result in a debit to the common stock account for the original par value, a debit to additional paid-in capital for the excess between the par value and the original sales price, a debit to retained earnings for any excess amounts paid above the original sales price and a credit to the treasury stock account for the price paid.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Forfeited shares are generally the result of an employee&amp;#x2019;s separation from the Company. Forfeitures of our service-, performance- and market-based share awards are discussed below. Such stock is held briefly as treasury stock and canceled during the year. At December 31, 2015 and 2014, there was no treasury stock held by the Company.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Upon the vesting of unvested common stock (or restricted stock) the Company may withhold shares, based on the employee&amp;#x2019;s election, in order to satisfy federal tax withholdings. The shares held by the Company are considered constructively retired and are retired shortly after withholding. The Company then remits the withholding taxes required by the taxing agencies. During 2015 and 2014, there were 96,076 and 8,120 shares withheld for tax purposes and retired.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Stock-based Compensation and Grants&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company has a stock-based incentive plan that is administered by the Compensation Committee of the Board of Directors (the &amp;#x201c;2001 Plan&amp;#x201d;). The 2001 Plan is in effect until May 2021 as a result of a May 2011 amendment to extend its term for an additional ten years. The 2001 Plan provides for the issuance of stock awards for up to 1,900,000 shares of the Company&amp;#x2019;s common stock. The Compensation Committee may reward employees and non-employees with various types of awards including but not limited to warrants, stock options, common stock, and unvested common stock (or restricted stock) vesting on service, performance or market criteria.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;At December 31, 2015, there were 614,921 shares of common stock available under the 2001 Plan.

In 2013, the Company issued 100,000 shares of unvested common stock to the Company&amp;#x2019;s former CEO which were accelerated and distributed to him upon his separation in January 2015. In 2014 and 2015, there were a total of 7,500 and 10,000 performance-based shares issued, respectively. In 2015, 13,750 of performance based shares were forfeited. In order to recognize compensation expense for these performance based shares, the Company must assess, at each reporting period, whether it is probable that the performance condition will be met. These shares must also be re-valued at each reporting period until they vest. At December 31, 2015 and 2014, the Company assessed that it would not be probable that the performance conditions would be met, as such; no expense was incurred during either year.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;On January 1, 2015, the Company launched a long- and short-term incentive program for certain employees.&amp;nbsp;&amp;nbsp;The short-term incentive plan is paid in cash if certain short-term achievements are met and the long-term incentive plan is paid with the Company&amp;#x2019;s stock if certain long-term achievements are met.&amp;nbsp;&amp;nbsp;The stock-based awards are awarded based in two parts; 50% is based on completing a service period of three years and 50% is based on the level of achievement of the Company&amp;#x2019;s total shareholder return (&amp;#x201c;TSR&amp;#x201d;) compared to the TSR of a designated peer group over a three-year period or a market based stock award.&amp;nbsp;&amp;nbsp;The service based awards are recorded as usual; however, the market-based awards of 86,483 shares were valued using a Monte Carlo simulation and their expense was included in the $1.2 million of total unvested and market-based awards discussed below. During the year ended December 31, 2015, 55,419 of these shares were forfeited and amortization expense was adjusted.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;At December 31, 2015, total unrecognized compensation cost related to unvested common and market-based stock was $3.1 million.

Compensation expense for unvested common stock (or restricted stock) and market-based grants were $1.2 million in 2015, and $0.8 million in each of 2014 and 2013. There were no proceeds received by the Company from the exercise of options in 2015 as there were no options outstanding in 2015, and in 2014 and 2013, the proceeds received were less than $0.1 million for each of these years.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 72; Value: 1 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company also awards common stock as part of its incentive plan with no service or performance vesting requirements.

Certain of the Company&amp;#x2019;s accounting policies require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion method, the valuation of long-term assets (including goodwill), and income taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:UseOfEstimates>

For investments in subsidiaries and construction joint ventures that are not wholly-owned, but where the Company exercises control, the equity held by the remaining owners and their portions of net income (loss) are reflected in the balance sheet line item &#x201c;Noncontrolling interests&#x201d; in &#x201c;Equity&#x201d; and the statement of operations line item &#x201c;Noncontrolling owners&#x2019; interests in earnings of subsidiaries,&#x201d; respectively.

This method is an acceptable modification of the equity method of accounting which is a common practice in the construction industry.

This determination focuses on identifying which owner or joint venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the entity or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect of requiring the Company to consolidate the entity in which we have a noncontrolling variable interest.

Certain of the Company&#x2019;s accounting policies require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion method, the valuation of long-term assets (including goodwill), and income taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"><div style="display: inline; font-style: italic;">Revenue Recognition</div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company is a general contractor which engages in various types of heavy civil construction projects principally for public (government) owners. Credit risk is minimal with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related costs. Credit risk with private owners is minimized because of statutory mechanics liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners. Refer to Note 16 for further information regarding the Company&#x2019;s concentration of risk.</div>    <!-- Field: Page; Sequence: 51; Value: 1 -->    <div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Revenues are recognized on the percentage-of-completion method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Changes in estimated revenues and gross margin during the year ended December 31, 2015 resulted in a net charge of $9.7 million included in operating loss, or $0.50 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders.

Changes in estimated revenues and gross margin during the year ended December 31, 2013 resulted in a net charge of $57.6 million included in operating loss, or $3.46 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Change orders are modifications of an original contract that effectively change the existing provisions of the contract without adding new scope or terms. Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Either we or our customers may initiate change orders.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company considers unapproved change orders to be contract variations for which we have customer approval for a change of scope but a price change associated with the scope change has not yet been agreed upon. Costs associated with unapproved change orders are included in the estimated cost to complete the contracts and are treated as project costs as incurred. The Company recognizes revenue equal to costs incurred on unapproved change orders when realization of price approval is probable. Unapproved change orders involve the use of estimates, and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting periods to reflect changes in estimates or final agreements with customers. Change orders that are unapproved as to both price and scope are evaluated as claims.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company considers claims to be amounts in excess of agreed contract prices that we seek to collect from our customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs. Claims are included in the calculation of revenue when realization is probable and amounts can be reliably determined to the extent costs are incurred. To support these requirements, the existence of the following items must be satisfied: 1. The contract or other evidence provides a legal basis for the claim; or a legal opinion has been obtained, stating that under the circumstances there is a reasonable basis to support the claim; 2. Additional costs are caused by circumstances that were unforeseen at the contract date and are not the result of deficiencies in the contractor&#x2019;s performance; 3. Costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and 4. The evidence supporting the claim is objective and verifiable, not based on management&#x2019;s feel for the situation or on unsupported representations. Revenues in excess of contract costs incurred on claims is recognized when an agreement is reached with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract. Costs associated with claims are included in the estimated costs to complete the contracts and are treated as project costs when incurred.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">There were $1.6 million in costs and estimated earnings in excess of billings at December 31, 2015 and $3.5 million in costs and estimated earnings in excess of billing at December 31, 2014, for contract change orders not approved by the customer.

Furthermore, we considered that each heavy civil construction project has similar characteristics, includes similar services, has similar types of customers and is subject to similar economic and regulatory environments which would allow aggregation of individual operating segments into one reportable segment if multiple operating segments existed.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company noted that even if our local offices were to be considered separate components of our heavy civil construction operating segment, those components could be aggregated into a single reporting unit for purposes of testing goodwill for impairment under Accounting Standards Codification 280 and EITF D-101 because our local offices all have similar economic characteristics and are similar in all of the following areas:</div>  <table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;">       <tr style="vertical-align: top">     <td style="width: 0.25in"></td>     <td style="width: 0.25in"><div style="display: inline; font-family: Symbol">&middot;</div></td>     <td style="text-align: justify">The nature of the products and services &#x2014; each of our local offices perform similar construction projects &#x2014; they build, reconstruct and repair roads, highways, bridges, airfields, ports, light rail and water, waste water and storm drainage systems.</td>    </tr>     </table>  <table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;">       <tr style="vertical-align: top">     <td style="width: 0.25in"></td>     <td style="width: 0.25in"><div style="display: inline; font-family: Symbol">&middot;</div></td>     <td style="text-align: justify">The nature of the production processes &#x2014; our heavy civil construction services rendered in the construction process for each of our construction projects performed by each local office is the same &#x2014; they excavate dirt, remove existing pavement and pipe, lay aggregate or concrete pavement, pipe and rail and build bridges and similar large structures in order to complete our projects.</td>    </tr>     </table>  <table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0; margin-bottom: 0; width: 700px;">       <tr style="vertical-align: top">     <td style="width: 0.25in"></td>     <td style="width: 0.25in"><div style="display: inline; font-family: Symbol">&middot;</div></td>     <td style="text-align: justify">The type or class of customer for products and services &#x2014; substantially all of our customers are federal and state departments of transportation, cities, counties, and regional water, rail and toll-road authorities.

Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

The Compensation Committee may reward employees and non-employees with various types of awards including, but not limited to, warrants, stock options, common stock, and unvested common stock (or restricted stock) vesting on service, performance or market criteria. The Company recognizes expense based on the grant-date fair value of the service award and amortizes the award based on accelerated or straight line methods. Awards based on performance vesting are subsequently remeasured at each reporting date through the settlement date. Awards that vest based on market criteria are valued using a valuation model that incorporates the probability of the Company meeting the stated criteria, such as the Monte-Carlo simulation, and the expense is amortized on a straight line basis over the term of the agreement.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 6pt 0">Upon the vesting of unvested common stock the Company may withhold shares, based on the employee&#x2019;s election, in order to satisfy federal tax withholdings.

The update is effective for public business entities issuing financial statements for the annual periods beginning after December 15, 2015, and interim periods within those annual periods. The Company retrospectively adopted the provisions of this ASU at December 31, 2015. Accordingly, $1.2 million of net deferred tax assets have been reclassified from current to non-current in the accompanying consolidated balance sheet as of December 31, 2014.

The guidance states that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company is currently accounting for its debt issuance costs for its Term Loan and line-of-credit Revolver Loan in this manner and would only expect a change in presentation of the deferred amounts related to the Term Loan upon adoption as required by ASU 2015-03.

The Third Amended and Restated Operating Agreement and the amended Management Agreement eliminated the buy/sell option and instead included the obligation for the Company to purchase Mr. Buenting&#x2019;s interest upon his death or permanent disability for $20 million or $18 million (subsequently increased to $20 million), respectively. In the event of Mr. Buenting&#x2019;s death or permanent disability, his estate representative, trustee or designee shall become the selling representative and sell his 50% interest to the Company. In order to fund the purchase of Mr. Buenting&#x2019;s interest, the Company has purchased term life insurance with a payout of $20 million in the event of Mr. Buenting&#x2019;s death. The Company will be the beneficiary and will also pay the premiums related to this life insurance contract. The life insurance proceeds of $20 million shall be used as full payment for Mr. Buenting&#x2019;s interest in the occurrence of his death. On June 2, 2015, the Company purchased an insurance policy with a five-year term on Mr. Buenting that provides a lump sum disability benefit in the principal sum of $20 million. &nbsp;In the event of Mr. Buenting&#x2019;s permanent total disability, the principal sum becomes payable to the Company, and in turn the Company is obligated to use the proceeds of the policy to purchase Mr. Buenting&#x2019;s 50% member&#x2019;s interest in RHB in accordance with the terms of the amended agreements.

The amendment resulted in a reduction of $0.6 million in the Company&#x2019;s earn-out liability, thereby reducing the total earn-out liability to $1.4 million on December 31, 2013. As part of the amendment, a payment of $0.8 million was made during the first quarter of 2014. The amendment increased the total available earn-out from $5.0 million to $10.0 million if certain EBITDA benchmarks are met. The amendment extended the earn-out period through December 31, 2017 and reduced the benchmark EBITDA for 2014 and 2015 to $1.5 million and increased it to $2.0 million in 2016 and 2017. This earn-out liability continues to be classified as a Level 3 fair value measurement and the unobservable inputs continue to be the forecasted EBITDA for the periods after the period being reported on through December 31, 2017. There was no yearly excess forecasted EBITDA in our calculation at December 31, 2015 of the minimum EBITDA benchmarks for the years 2016 through 2017. The discounted present value of the additional purchase price was estimated to be $0.3 million as of December 31, 2014. The undiscounted earn-out liability as of December 31, 2015 is minimal and could increase by $9.3 million if EBITDA during the earn-out period increases $18.5 million or more and could decrease by the full amount of the liability for the year if EBITDA does not exceed the minimum threshold for that year. Each year is considered a discrete earnings period and future losses by JBC, if any, would not reduce the Company&#x2019;s liability in years in which JBC has exceeded its earnings benchmark. Any significant increase or decrease in actual EBITDA compared to the forecasted amounts would result in a significantly higher or lower fair value measurement of the additional purchase price. This liability is included in other long-term liabilities on the accompanying consolidated balance sheets. As part of recording the present value of this liability, the Company incurs accreted interest expense for the passage of time until the time of settlement. The Company incurred accreted interest expense of $0.3 million for the year ended December 31, 2014. As part of the updated EBITDA forecast, the Company reduced its liability to zero and recorded interest income of $0.3 million in the first quarter of 2015. There has been minimal change in the value of this liability; therefore, the interest income was $0.3 million for the year ended December 31, 2015.</div>  <div style=" font-size: 10pt; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><div style="display: inline; font-weight: bold;"><div style="display: inline; font-style: italic;">Noncontrolling Interests&#x2019; &#x2013; Call Options</div></div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the year ended December 31, 2015, the Company entered into several agreements, with RHB and with Myers, which gives the 50% owners of these entities the option to buy the Company&#x2019;s 50% interest in these entities for $10,000 should the Company ever become subject to the repossession or disposition of its collateral as defined in the Company&#x2019;s new debt agreement with Nations or if the Company dissolves or becomes insolvent.

This determination focuses on identifying which owner or joint venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the entity or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect of requiring the Company to consolidate the entity in which we have a noncontrolling variable interest. Where the Company has determined that it is appropriate to consolidate a VIE which it owns a 50% or less interest, the equity held by the remaining owners and their portions of net income (loss) are reflected in the balance sheet line item &#x201c;Noncontrolling interests&#x201d; in &#x201c;Equity&#x201d; and the statement of operations line item &#x201c;Noncontrolling owners&#x2019; interests in earnings of subsidiaries,&#x201d; unless the equity interest is deemed to be mandatorily redeemable. Refer to Note 2 regarding the Company&#x2019;s mandatorily redeemable obligations.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 13.7pt; margin: 6pt 0">On August 1, 2011, the Company purchased a 50% limited partner interest in Myers. Myers is a construction limited partnership located in California and was acquired in order to expand the geographic scope of the Company&#x2019;s operations into California. The Company has determined that Myers is a VIE for which the Company is the primary beneficiary and has consolidated Myers into the Company&#x2019;s financial statements.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 13.7pt; margin: 6pt 0">The determination that Myers is a VIE and that the Company is the primary beneficiary is primarily due to the following factors. The partnership agreement requires that Sterling provide funding as needed, when available, to the limited partnership. In addition, the partnership is relying on the Company&#x2019;s surety bonding capacity in order to bid and perform large construction jobs resulting in the Company having joint and several liability for completion of such jobs, and the Company will provide management to the partnership to oversee bidding and management of larger projects. Although the Company will receive 50% of the income from the partnership, it may suffer more than 50% of any losses as a result of its obligation to provide funding and its obligations under the surety bonds. Because the Company exercises primary control over activities of the partnership and it is exposed to the majority of potential losses of the partnership, the Company consolidated Myers within the Company&#x2019;s financial statements from August 1, 2011, the date of acquisition.</div>  <!-- Field: Page;

Joint venture partners typically provide independently prepared estimates, furnish employees and equipment, enhance bonding capacity and often also bring local knowledge and expertise. We select our joint venture partners based on our analysis of their construction and financial capabilities, expertise in the type of work to be performed and past working relationships with us, among other criteria.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We participate in various construction joint venture partnerships. Generally, each construction joint venture is formed to accomplish a specific project and is jointly controlled by the joint venture partners. The joint venture agreements typically provide that our interests in any profits and assets, and our respective share in any losses and liabilities that may result from the performance of the contract are limited to our stated percentage interest in the venture. We have no significant commitments beyond completion of the contract with the customer.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Joint venture contracts with project owners typically impose joint and several liability on the joint venture partners. Although our agreements with our joint venture partners provide that each party will assume and pay its share of any losses resulting from a project, if one of our partners is unable to pay its share, we would be fully liable under our contract with the project owner. Circumstances that could lead to a loss under these guarantee arrangements include a partner&#x2019;s inability to contribute additional funds to the venture in the event that the project incurs a loss or additional costs that we could incur should the partner fail to provide the services and resources toward project completion that had been committed to in the joint venture agreement. Historically, the Company has not incurred a liability related to the nonperformance of a joint venture partner.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Under a joint venture agreement, one partner is typically designated as the sponsor or manager. The sponsoring partner typically provides all administrative, accounting and most of the project management support for the project and generally receives a fee from the joint venture for these services. We have been designated as the sponsoring partner in certain of our current joint venture projects and are a non-sponsoring partner in others.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Under GAAP, the Company must determine whether each joint venture in which it participates is a variable interest entity. This determination focuses on identifying which joint venture partner, if any, has the power to direct the activities of a joint venture and the obligation to absorb losses of the joint venture or the right to receive benefits from the joint venture in excess of their ownership interests and could have the effect of requiring us to consolidate joint ventures in which we have a noncontrolling variable interest. At December 31, 2015, we had no participation in a joint venture where we had a material non-majority variable interest.</div>    <!-- Field: Page; Sequence: 62; Value: 1 -->    <div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Where we are a noncontrolling venture partner, we account for our share of the operations of such construction joint ventures on a pro rata basis using proportionate consolidation on our consolidated statements of operations and as a single line item (&#x201c;Receivables from and equity in construction joint ventures&#x201d;) in the consolidated balance sheets. This method is an acceptable modification of the equity method of accounting which is a common practice in the construction industry.

<td class="text"><div style="display: inline; font-family: times new roman; font-size: 10pt"><table cellpadding="0" cellspacing="0" style="font-size: 10pt; font-weight: bold; margin-top: 6pt; margin-bottom: 6pt; width: 700px;">       <tr style="vertical-align: top">     <td style="width: 0"></td>     <td style="width: 0.25in">8.</td>     <td>Goodwill</td>    </tr>     </table>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Goodwill represents the excess of the cost of companies acquired over the fair value of their net assets at the dates of acquisition. GAAP requires that goodwill not be amortized and that goodwill is to be tested for impairment at least annually at the reporting unit level. The Company tests for goodwill impairment annually on October 1<div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;">st</div> unless impairment triggers exist at interim periods. There are two steps involved in the testing of goodwill, excluding a qualitative analysis. The first step compares the book value of the Company&#x2019;s stock (stockholders&#x2019; equity or net assets) to the adjusted fair market value of those shares. If the adjusted fair value of the stock is greater than the calculated book value of the stock, goodwill is deemed not to be impaired and no further testing is required. If the adjusted fair value is less than the calculated book value, then step two of determining the fair value of net assets must be taken to determine the impairment amount.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">To determine the fair value of the Company&#x2019;s net assets, the Company used the weighted average of the following valuation techniques: the market approach, which uses market capitalization information plus a control premium and an income approach, which uses a discounted cash flow methodology. The market approach includes level one fair value inputs, such as the Company&#x2019;s stock price, at the date of our test, and level two fair value inputs, such as the control premiums based on prior year sales transactions of construction contractors and engineering services, similar sized transactions based on the Company&#x2019;s market capitalization, and all-inclusive total industries transactions. The income approach includes level three inputs such as the Company&#x2019;s calculated weighted average cost of capital and future income projections that include assumptions about revenue and gross profit growth, along with other assumptions.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the first and third quarters of 2015, the Company noted there was an impairment trigger present during these interim periods and performed step one of the impairment test discussed above. Based on the results of our goodwill impairment tests, we concluded that there was not an impairment of goodwill during these periods. In addition, as part of our 2015 and 2014 annual tests, we determined that the fair value of the Company&#x2019;s equity continues to be more than the carrying value of the Company&#x2019;s equity by approximately 21% and 19%, respectively.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">At December 31, 2015, we had goodwill with a remaining carrying amount of approximately $54.8 million. Testing under step one in 2014 and 2013 also did not indicate that the adjusted fair value of the Company&#x2019;s stock was less than its book value.</div></div><span></span>

The amount of the Revolving Loan that may be borrowed from time to time is determined quarterly and may not exceed $20.0 million. In addition, the sum of the outstanding balances of the Equipment-based Facility may not exceed the lesser of $40.0 million or 65% of the appraised value of the collateral pledged for the loans. At December 31, 2015, the Company had approximately a borrowing base of $29.6 million, which was the result of calculating 65% of the appraised value (where appraised value equals net operating liquidated value) of the Company&#x2019;s collateral. The Revolving Loan may be utilized by the Company to provide ongoing working capital and for other general corporate purposes.</div>    <!-- Field: Page; Sequence: 64; Value: 1 -->    <div style="page-break-before: always; margin-top: 6pt; margin-bottom: 12pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Equipment-based Facility bears interest at an initial fixed annual rate of 12%, which is subject to (i) a decrease of up to two percentage points based on the Company's fixed charge coverage ratio for each of the most recently ended four quarters beginning with the four quarters ending June 30, 2016; and (ii) an increase of up to two percentage points beginning December 31, 2015 based on the fixed charge coverage ratio at the end of the following four quarters. Principal on the Term Loan is payable in 47 monthly installments (with accrued interest) with a final payment of the then outstanding principal amount on May 29, 2019. Up to $5.0 million of the Term Loan may be prepaid in any year, but subject to a pre-payment fee that declines as the Term Loan nears maturity. Outstanding Revolving Loans are payable in full thirty days before the maturity date of the Term Loan.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Equipment-based Facility is secured by all of the Company's personal property except accounts receivable, including all of its construction equipment, which forms the basis of availability under the Revolving Loan. The Equipment-based Facility is also secured by one-half of the equipment of the Company's 50%-owned affiliates, Road and Highway Builders, LLC and Myers &amp; Sons Construction, L.P. pursuant to a separate security agreement with those entities. If a default occurs, Nations may exercise the Company's rights in the collateral, with all of the rights of a secured party under the Uniform Commercial Code, including, among other things, the right to sell the collateral at public or private sale.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The proceeds of the Term Loan of $20.0 million and our initial draw of $14.6 million under the Revolving Loan were utilized by the Company to repay the balance outstanding and terminate the Prior Credit Facility and for other general corporate purposes.

A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended December 31, 2015. The cumulative three-year period loss that remained at December 31, 2015 was the result of write-downs recorded during the past three years. Such objective evidence limits the ability to consider other subjective evidence such as our projections for future growth. On the basis of this evaluation, as of December 31, 2015, a valuation allowance of $56.4 million has been recorded on the net deferred tax assets including federal and state net operating losses as they are not likely to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted in the future if objective negative evidence or cumulative losses are no longer present and additional weight may be given to subjective evidence such as our projections for growth.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">If our assumptions change and we determine we will be able to realize these deferred tax assets, the tax benefits relating to any reversal of the valuation allowance on deferred tax assets as of December 31, 2015, will be accounted for as follows: approximately $46.8 million will be recognized as a reduction of income tax expense and $9.6 million will be recorded as an increase in equity.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">On September 13, 2013, the U.S. Treasury Department and the I.R.S. issued final regulations that address costs incurred in acquiring, producing, or improving tangible property (the &quot;tangible property regulations&quot;). The tangible property regulations are generally effective for tax years beginning on or after January 1, 2014. The Company intends to adopt the tax treatment of expenditures to improve tangible property and the capitalization of inherently facilitative costs to acquire tangible property as of January 1, 2014. The tangible property regulations will require the Company to make additional tax accounting method changes as of January 1, 2014; however, management does not anticipate the impact of these changes to be material to the Company&#x2019;s consolidated financial position, its results of operations, or both.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">As a result of the Company&#x2019;s analysis, management has determined that the Company does not have any material uncertain tax positions. The Company&#x2019;s policy is to recognize interest related to any underpayment of taxes as interest expense, and penalties as administrative expenses. No interest or penalties have been accrued at December 31, 2015 or 2014. The Company&#x2019;s U.S. federal income tax returns for 2012 and later years are open and subject to examination by the I.R.S. In addition, the Company&#x2019;s state income tax returns for 2011 and later years are open and subject to examination.</div></div><span></span>

Subject to the rights of holders of any then outstanding shares of preferred stock, common stockholders are entitled to receive ratably any dividends that may be declared by the Board of Directors out of funds legally available for that purpose. Holders of common stock are entitled to share ratably in net assets upon any dissolution or liquidation after payment of provision for all liabilities and any preferential liquidation rights of our preferred stock then outstanding. Common stock shares are not subject to any redemption provisions and are not convertible into any other shares of capital stock. The rights, preferences and privileges of holders of common stock are subject to those of the holders of any shares of preferred stock that may be issued in the future.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Board of Directors may authorize the issuance of one or more classes or series of preferred stock without stockholder approval and may establish the voting powers, designations, preferences and rights and restrictions of such shares.

In August 2010, the Company announced an increase to the share-repurchase program to purchase an additional $5 million in shares of common stock, for a total up to $10 million. The specific timing and amount of repurchase will vary based on market conditions, securities law limitations and other factors. There were no shares repurchases in 2015 and 2014 related to the share-repurchase program.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company accounts for the repurchase of treasury shares under the cost method. When shares are repurchased, cash is paid and the treasury stock account is debited for the price paid. Under the cost method, retirement of treasury stock would result in a debit to the common stock account for the original par value, a debit to additional paid-in capital for the excess between the par value and the original sales price, a debit to retained earnings for any excess amounts paid above the original sales price and a credit to the treasury stock account for the price paid.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Forfeited shares are generally the result of an employee&#x2019;s separation from the Company. Forfeitures of our service-, performance- and market-based share awards are discussed below. Such stock is held briefly as treasury stock and canceled during the year. At December 31, 2015 and 2014, there was no treasury stock held by the Company.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Upon the vesting of unvested common stock (or restricted stock) the Company may withhold shares, based on the employee&#x2019;s election, in order to satisfy federal tax withholdings. The shares held by the Company are considered constructively retired and are retired shortly after withholding. The Company then remits the withholding taxes required by the taxing agencies. During 2015 and 2014, there were 96,076 and 8,120 shares withheld for tax purposes and retired.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0"><div style="display: inline; font-weight: bold;"><div style="display: inline; font-style: italic;">Stock-based Compensation and Grants</div></div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company has a stock-based incentive plan that is administered by the Compensation Committee of the Board of Directors (the &#x201c;2001 Plan&#x201d;). The 2001 Plan is in effect until May 2021 as a result of a May 2011 amendment to extend its term for an additional ten years. The 2001 Plan provides for the issuance of stock awards for up to 1,900,000 shares of the Company&#x2019;s common stock. The Compensation Committee may reward employees and non-employees with various types of awards including but not limited to warrants, stock options, common stock, and unvested common stock (or restricted stock) vesting on service, performance or market criteria.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">At December 31, 2015, there were 614,921 shares of common stock available under the 2001 Plan.

Gross profit was depressed by downward revisions of gross profit on problem projects, the majority of which are being constructed in Texas, primarily due to spot shortages of commodities, over-stretched sub-contractors and vendors, and intense competition for craft labor.&nbsp;</div></div><span></span>

These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion method, the valuation of long-term assets (including goodwill), and income taxes.

Credit risk is minimal with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related costs. Credit risk with private owners is minimized because of statutory mechanics liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners. Refer to Note 18 for further information regarding the Company&#x2019;s concentration of risk.</div><div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Revenues are recognized on the percentage-of-completion method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined.</div><div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Changes in estimated revenues and gross margin during the year ended December 31, 2015 resulted in a net charge of $9.6 million included in operating loss, or $0.50 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders. Changes in estimated revenues and gross margin during the year ended December 31, 2014 resulted in a net charge of $9.1 million included in operating loss, or $0.50 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders. Changes in estimated revenues and gross margin during the year ended December 31, 2013 resulted in a net charge of $57.6 million included in operating loss, or $3.46 per diluted share attributable to Sterling common stockholders, included in net loss attributable to Sterling common stockholders.</div><div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Change orders are modifications of an original contract that effectively change the existing provisions of the contract without adding new scope or terms. Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Either we or our customers may initiate change orders.</div><div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company considers unapproved change orders to be contract variations for which we have customer approval for a change of scope but a price change associated with the scope change has not yet been agreed upon. Costs associated with unapproved change orders are included in the estimated cost to complete the contracts and are treated as project costs as incurred. The Company recognizes revenue equal to costs incurred on unapproved change orders when realization of price approval is probable. Unapproved change orders involve the use of estimates, and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting periods to reflect changes in estimates or final agreements with customers. Change orders that are unapproved as to both price and scope are evaluated as claims.</div><div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company considers claims to be amounts in excess of agreed contract prices that we seek to collect from our customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs. Claims are included in the calculation of revenue when realization is probable and amounts can be reliably determined. To support these requirements, the existence of the following items must be satisfied: 1. The contract or other evidence provides a legal basis for the claim; or a legal opinion has been obtained, stating that under the circumstances there is a reasonable basis to support the claim; 2. Additional costs are caused by circumstances that were unforeseen at the contract date and are not the result of deficiencies in the contractor&#x2019;s performance; 3. Costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and 4. The evidence supporting the claim is objective and verifiable, not based on management&#x2019;s feel for the situation or on unsupported representations. Revenue in excess of contract costs incurred on claims is recognized when an agreement is reached with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract. Costs associated with claims are included in the estimated costs to complete the contracts and are treated as project costs when incurred.</div><div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">There <div style="display: inline; background-color: yellow">was $3.5 million</div> in costs and estimated earnings in excess of billings at December 31, 2015 and $3.5 million in costs and estimated earnings in excess of billing at December 31, 2014, for contract change orders not approved by the customer. In addition, the Company recorded <div style="display: inline; background-color: yellow">$xx million</div> in revenues related to claims during the year ended December 31, 2015, and did not record revenues related to claims during the years ended December 31, 2014 and 2013.</div><div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our contracts generally take 12 to 36 months to complete.

Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.
