to SEC rules and regulations. The condensed consolidated financial statements reflect, in the opinion of management, all normal
recurring adjustments necessary to present fairly the Company&#8217;s financial position at June 30, 2017 and the results of operations
and cash flows for the periods presented. The December 31, 2016 condensed consolidated balance sheet data herein was derived from
audited financial statements, but as discussed above, does not include all disclosures required by GAAP. Interim results may be
subject to significant seasonal variations and the results of operations for the three and six months ended June 30, 2017 are not
necessarily indicative of the results expected for the full year or subsequent quarters.</p>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">On April 3, 2017, the Company consummated
the acquisition of 100% of the outstanding stock of Tealstone Residential Concrete, Inc. and Tealstone Commercial, Inc. (collectively,
&#8220;<i>Tealstone</i>&#8221;) and entered into a Loan and Security Agreement providing for a term loan of $85,000,000 with a
maturity date of April 4, 2022, which replaced the then existing debt facility. We have determined that with the acquisition of
Tealstone there are two reportable segments: heavy civil construction and residential construction. Refer to Note 13 for a discussion
of reportable segments and related financial information.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><i>Principles of Consolidation</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The accompanying condensed 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 and joint ventures,&#8221;
respectively. For investments in subsidiaries that are not wholly-owned, but where the Company exercises control and where the
Company has a mandatorily redeemable interest, the equity held by the remaining owners and their portion of net income (loss) is
reflected in the balance sheet line item &#8220;Members&#8217; interest subject to mandatory redemption and undistributed earnings&#8221;
and the statement of operations line item &#8220;Other operating income (expense), net,&#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%. Refer to Note 4 for further information regarding the Company&#8217;s Subsidiaries
and Joint Ventures with Noncontrolling Owners&#8217; Interest.</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 condensed consolidated statements of operations and as a single line
item (&#8220;Receivables from and equity in construction joint ventures&#8221;) in the condensed 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 5 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 GAAP, 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 it has a noncontrolling
variable interest. Refer to Note 6 for further information regarding the Company&#8217;s consolidated VIE.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><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 the accompanying condensed
consolidated 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&rsquo;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, purchase accounting, including
intangibles and 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 0.05in 6pt 0"><i>Reclassification</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 2pt 0.05in 2pt 0">Reclassifications have been made
to historical financial data on our condensed consolidated financial statements to conform to our current year presentation.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><i>Revenue Recognition</i></p>

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

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company 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 mechanic&rsquo;s
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">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 0pt 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 0pt 2pt">Changes in estimated revenues and gross
margin resulted in a net charge of $1.8 million and a net charge of $1.1 million during the three months and six months ended
June 30, 2017, respectively, included in &ldquo;operating income (loss)&rdquo; on the condensed consolidated statements of operations<FONT STYLE="color: red">.
</FONT>Changes in estimated revenues and gross margin resulted in a net gain of $0.7 million and a net charge of $0.5 million
during the three months and six months ended June 30, 2016, respectively, included in &ldquo;operating income (loss)&rdquo; on
the condensed consolidated statements of operations<FONT STYLE="color: red">.</FONT></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0pt 2pt">Change orders are modifications of an original
contract that effectively change the existing provisions of the contract without adding new provisions 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 0.05in 2pt 0">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
costs 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 0.05in 2pt 0">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: (i) 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; (ii)
Additional costs are caused by circumstances that were unforeseen at the contract date and are not the result of deficiencies
in the contractor&rsquo;s performance; (iii) Costs associated with the claim are identifiable or otherwise determinable and are
reasonable in view of the work performed; and (iv) The evidence supporting the claim is objective and verifiable, not based on
management&rsquo;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.&nbsp;</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0">&nbsp;</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0">The Company has projects where we
are in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with our customers. The Company
is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated
with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope
which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information
has been provided to our customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution
is not reached, legal action will be taken.&nbsp;</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0">Based upon our review of the provisions
of our contracts, specific costs incurred and other related evidence supporting the unapproved change orders, claims and our entitled
unpaid project price, together with the views of the Company&rsquo;s outside claim consultants, we concluded that including the
unapproved change order, claim and entitled unpaid project price amounts of $1.4 million, $12.0 million and $3.9 million, respectively,
at June 30, 2017, and $2.2 million, $9.2 million and $3.9 million, respectively, at December 31, 2016, in &ldquo;Costs and estimated
earnings in excess of billings on uncompleted contracts&rdquo; on our condensed consolidated balance sheets was in accordance with
GAAP. We expect these matters will be resolved without a material adverse effect on our financial statements. However, unapproved
change order and claim amounts are subject to negotiations which may cause actual results to differ materially from estimated and
recorded amounts.</P>

<p style="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><i>Financial Instruments and Fair Value</i></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">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&rsquo;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 contracts receivable, accounts payable, notes payable, and a term loan (the &ldquo;Loan&rdquo;)
with Oaktree Capital Management, L.P.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The recorded values of cash and

their liquidity and/or short-term nature.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Refer to Note 8 regarding the fair

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">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 0.05in 2pt 0.25in">Level 1 Inputs &#8211; Based
upon quoted prices for identical assets in active markets that the Company has the ability to access at the measurement date.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in">Level 2 Inputs &#8211; 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.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in">Level 3 Inputs &#8211; Based
on unobservable inputs reflecting the Company&#8217;s own assumptions about the assumptions that market participants would use
in pricing the asset based on the best information available.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">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.</p>

Pronouncements</i></b></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">In January 2017, the Financial Accounting
Standards Board (&#8220;FASB&#8221;) issued guidance in Accounting Standards Update (&#8220;ASU&#8221;) No. 2017-04 &#8220;Intangibles-Goodwill
and Other&#8221; (Topic 350) which simplifies and eliminates step 2 of the current two step goodwill impairment test. This guidance
is effective for public business entities for annual or any interim goodwill impairment tests in fiscal years beginning after December
15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January
1, 2017. The Company early adopted this ASU on January 1, 2017. The adoption did not have a material impact on our consolidated
financial statements or related disclosures.</p>

<p style="font-size: 10pt; text-align: left; text-indent: -0.25in; margin: 6pt 0 6pt 0.25in"><b><i>Recently Issued Accounting Pronouncements</i></b></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">In May 2017, the FASB issued guidance
in ASU No. 2017-09 &ldquo;Compensation&mdash;Stock Compensation&rdquo; (Topic 718): Scope of Modification Accounting, which provides
guidance to assist entities with evaluating which changes to the terms or conditions of a share-based payment award require an
entity to apply modification accounting. The amendments in this update provide a screen to determine when an entity should account
for the effects of a modification. This guidance is effective for all entities for annual periods and interim periods within those
annual periods, beginning after December 15, 2017. The Company expects to adopt this guidance as required and does not expect
a material impact to the Company&rsquo;s consolidated financial statements.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">In January 2017, the FASB issued
guidance in ASU No. 2017-01 &#8220;Business Combinations&#8221; (Topic 805): Clarifying the Definition of a Business, which adds
guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets
or businesses. The amendments in this update provide a screen to determine when a set of assets and activities is not a business,
provide a framework to assist entities in evaluating whether both an input and a substantive process are present and narrow the
definition of the term output to be consistent with Topic 606. This guidance is effective for public business entities for annual
periods beginning after December 15, 2017 including interim periods within those periods. The Company expects to adopt this guidance
as required and does not expect a material impact to the Company&#8217;s consolidated financial statements.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">In November 2016, the FASB issued
guidance in ASU No. 2016-18 &#8220;Statement of Cash Flows&#8221; (Topic 230): Restricted Cash (a consensus of the FASB Emerging
Issues Task Force). The amendments in this Update require that a statement of cash flows explain the change during the period in
the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore,
amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents
when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance is
effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal
years. Early adoption is permitted, including adoption in an interim period. The Company expects to adopt this guidance as required
and does not expect a material impact to the Company&#8217;s consolidated financial statements other than to the presentation of
restricted cash on our consolidated statements of cash flows.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In February 2016, the FASB issued its new
lease accounting guidance in ASU No. 2016-02, &#8220;Leases&#8221; (Topic 842). 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. The new standard is effective for
annual periods beginning after December 15, 2018, including interim periods within those fiscal years. 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 May 2014, the FASB issued ASU 2014-09,
&#8220;Revenue from Contracts with Customers.&#8221; The core principle of the guidance is that an entity should recognize revenue
to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which an entity
expects to be entitled in exchange for those goods or services. Under the new guidance, an entity is required to perform the following
five steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine
the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue
when (or as) the entity satisfies a performance obligation. 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. Additional ASUs have been issued
that are part of the overall new revenue guidance, including: ASU No. 2016-08, &#8220;Principal versus Agent Considerations (Reporting
Revenue Gross versus Net),&#8221; ASU No. 2016-10, &#8220;Identifying Performance Obligations and Licensing,&#8221; and ASU 2016-12,
&#8220;Narrow Scope Improvements and Practical Expedients.&#8221;</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The new revenue recognition standard prescribes a five-step model that focuses on transfer of control
and entitlement to payment when determining the amount of revenue to be recognized.&nbsp;The new model requires companies to identify
contractual performance obligations and determine whether revenue should be recognized at a point in time or over time for each
of these obligations. We expect that revenue generated from our fixed unit price contracts, which represent a significant portion
of our total contracts, will continue to be recognized over time utilizing the cost-to-cost measure of progress consistent with
our current practice. Therefore, we do not expect a material impact to the Company&rsquo;s Consolidated Financial Statements related
to fixed unit price contracts. We also expect our revenue recognition disclosures to significantly expand due to the new qualitative
and quantitative requirements under the standard. The Company is currently determining the impact of the new standard on our lump-sum,
cost-plus and other than fixed unit price contracts. Because the standards will impact our business processes, systems and controls,
the Company is also developing a comprehensive change management project plan to guide the implementation. <FONT STYLE="font-size: 10pt">We
will adopt the requirements of the new standard effective January 1, 2018 and intend to use the modified retrospective adoption
approach, but will not make a final decision on the adoption method until later in 2017.</FONT></p></div><p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"></p>

the acquisition (the &ldquo;Tealstone Acquisition&rdquo;) of 100% of the outstanding stock of Tealstone Residential Concrete,
Inc. and Tealstone Commercial, Inc. (collectively, &ldquo;<I>Tealstone</I>&rdquo;) from the stockholders thereof (the &ldquo;Sellers&rdquo;)
for consideration consisting of $55,000,000 in cash, 1,882,058 shares of the Company&rsquo;s common stock (the &ldquo;<I>Placement
Shares</I>&rdquo;), and $5,000,000 of promissory notes issued to the Sellers. In addition, the Company will make $2,500,000 and
$7,500,000 of deferred cash payments on the second and third anniversaries of the closing date, respectively, and up to an aggregate
of $15,000,000 in earn-out payments may be made on the first, second, third and fourth anniversaries of the closing date to continuing
Tealstone management or their affiliates if specified financial performance levels are achieved. Tealstone focuses on concrete
construction of residential foundations, parking structures, elevated slabs and other concrete work for leading homebuilders,
multi-family developers and general contractors in both residential and commercial markets. This acquisition enables expansion
into adjacent markets and diversification of revenue streams and customer base with higher margin work.</p>

2017, we entered into a definitive agreement to sell one of our Texas subsidiary&rsquo;s office, equipment shop and yard facility,
which is in Texas. The property had a net book value of $4.1 million, and we expect to receive $3.2 million, after selling costs,
once the transaction has closed in the third quarter of 2017. As such, we have reclassified and included in &ldquo;other current
assets&rdquo; in our condensed consolidated balance sheet and recorded a $0.9 million write-down to fair value that has been recorded
in &ldquo;other operating income (expense), net&rdquo; for the quarter ended June 30, 2017.</P>

principal payments; however, the Company is required to prepay the Loan, and in certain cases pay a prepayment premium thereon,
with proceeds received from the issuances of debt or equity, transfers, events of loss and extraordinary receipts. The Company
is required to make an offer quarterly to the lenders to prepay the Loan in an amount equal to 75% of its excess cash flow, plus
accrued and unpaid interest thereon and a prepayment premium.</p>

expenditures, make investments, and pay dividends. In addition, the Company is required to maintain the following principal financial

of Tealstone, the Company has reviewed its reportable segments, operating segments and reporting units. Based on our review, we
have concluded that our operations consist of two reportable segments, two operating segments and two reporting unit components:
heavy civil construction and residential construction. In making this determination, the Company considered the discrete financial
information used by our Chief Operating Decision Maker (&ldquo;CODM&rdquo;). Based on this approach, the Company noted that the
CODM organizes, evaluates and manages the financial information around the aggregation of heavy civil construction projects and
the entire residential construction division when making operating decisions and assessing the Company&rsquo;s overall performance.
Furthermore, we considered the differences between the types of work performed in each reporting unit. 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. Projects in our heavy civil construction segment typically last for several years, involve several
subtasks and are accounted for using the percentage of completion method. Conversely, our residential construction projects typically
consist of a high volume of independent units performed for customers that are billed, paid and accounted for as the individual
units are completed. Each job performed in our residential construction segment typically takes less than one month to complete.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Segment reporting is aligned based
upon the services offered by our two operating groups, which represent our reportable segments: Heavy Civil Construction and Residential
Construction, as mentioned above. Our chief operating decision maker evaluates the performance of the aforementioned operating
groups based upon revenue and income from operations. Each operating group&rsquo;s income from operations reflects corporate costs,
allocated based primarily upon revenue.</P>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Sterling Construction Company, Inc. (&ldquo;Sterling&rdquo;
or &ldquo;the Company&rdquo;), is a leading heavy civil construction company that specializes in building and reconstruction of
transportation infrastructure, water infrastructure, and residential and commercial concrete projects in Texas, Utah, Nevada,
Colorado, Arizona, California, Hawaii, and other states in which there are construction opportunities. Our heavy civil construction
projects include highways, roads, bridges, airfields, ports, light rail, water, wastewater and storm drainage systems, multi-family
homes, commercial projects and parking structures. Our residential concrete construction projects include concrete foundations
for single-family homes.</P>

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

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0">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 two reportable segments, two operating segments and two reporting unit components: heavy civil
construction and residential construction. In making this determination, the Company considered the discrete financial information
used by our Chief Operating Decision Maker (&ldquo;CODM&rdquo;). Based on this approach, the Company noted that the CODM organizes,
evaluates and manages the financial information around the aggregation of heavy civil construction projects and the entire residential
construction division when making operating decisions and assessing the Company&rsquo;s overall performance. Furthermore, we considered
the differences between the types of work performed in each reporting unit. 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.
Projects in our heavy civil construction segment typically last for several years, involve several subtasks and are accounted
for using the percentage of completion method. Conversely, our residential construction projects typically consist of a high volume
of independent units performed for customers that are billed, paid and accounted for as the individual units are completed. Each
job performed in our residential construction segment typically takes less than one month to complete.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Market outlook: Our core heavy civil business, through June 30,2017, was primarily driven by Federal and
state funding. The 2015 passage of the federally funded five-year $305 billion surface transportation bill will increase the annual
federal highway investment by 15.1% over the five-year period from 2016 to 2020. In addition to the Federal program, several of
the states in our key markets have instituted actions to further increase annual spending. In Texas, two constitutional amendments
were passed, which will increase the annual funds allocated to transportation projects by $4.0 billion to $4.5 billion per year.
In Utah, a 20% gas tax increase was put into effect January 1, 2016, which is the first state gas tax increase in 18 years. Furthermore,
in 2017, a bill was passed authorizing the issuance of up to $1 billion in bonds for use in the state&rsquo;s highway projects.
In addition, a 1-cent sales tax increase was approved in Los Angeles, California in 2016 that will provide $3 billion a year for
local road, bridge and transit projects. See &ldquo;Item 1. Business&mdash;Our Markets, Competition and Customers&rdquo; in our
2016 Form 10-K for a more detailed discussion of our markets and their funding sources.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Bid discipline and project execution:
To ensure that we take full advantage of the improved market conditions and maximize profitability we have completed an extensive
evaluation of our projects&#8217; historical success based on project size, end customer, product delivered and geography. The
knowledge gained has now been incorporated into a more formal and rigorous bid evaluation and approval process, which along with
the institution of common processes, we believe will enable us to focus our resources on the most beneficial projects and significantly
reduce our risk. In addition, in order to strengthen these processes and capitalize further on the improved market conditions,
we appointed a Chief Operating Officer late in the first quarter of 2016.</p>

compared with the Prior Period. The increase in both the Current Quarter as compared to the Prior Quarter and the Current
Period as compared to the Prior Period is primarily the result of the April 3, 2017, Tealstone Acquisition. Revenues
increased approximately $43 million related to the Tealstone Acquisition. The majority of the remaining net increase of $14
million in the Current Quarter is attributable to Utah projects as a result of a ramp up in a new 2017 construction joint
venture project. The majority of the remaining $41 million net increase in the Current Period was also primarily attributable
to Utah projects as a result of a ramp up in a new 2017 construction joint venture project and projects in Texas where
improved weather conditions aided in increased productivity.</p>

Our gross margins increased to 10.2% and 8.6% in the Current Quarter and Current Period, respectively, as compared to 8.2% and
6.0% in the Prior Quarter and Prior Period, respectively. The increase in gross margin during the Current Quarter as compared to

Acquisition adding approximately 2.0% gross margin to the Current Quarter and 1.4% gross margin to the Current Period.</P>

139 and 124 heavy civil contracts-in-progress, respectively, which were less than 90% complete. These contracts are of various
sizes, of different expected profitability and in various stages of completion. The nearer a contract progresses toward completion,
the more we are able to refine our estimate of total revenues (including incentives, delay penalties, change orders and claims),
costs and gross profit. Thus, gross profit as a percent of revenues can increase or decrease from comparable and subsequent quarters
due to variations among contracts and depending upon the stage of completion of contracts.</p>

redemption and undistributed earnings.&rdquo; The change in other operating income (expense) income, net of $0.5 million during
the Current Quarter and $1.1 million during the Current Period was primarily due to a fair value write-down of $0.9 million on
one of our Texas buildings that is under contract to be sold in the third quarter and transaction costs of $0.3 million related

by operating activities was $12.3 million compared to net cash provided of $26.7 million in the Prior Period. The drivers of operating
activities cash flows were primarily the result of our improvement in net income discussed above, non-cash items, the change in
our accounts receivable, inventory, net contracts in progress and accounts payable balances (collectively, &ldquo;Contract Capital&rdquo;)
as discussed below.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The significant non-cash items included in operating activities include depreciation and amortization expense,
which were $8.4 million in the Current Period and $8.1 million in the Prior Period. Depreciation and amortization expense has
increased from the Prior Period to the Current Period as a result of our April 3, 2017 acquisition where we acquired identified
intangible assets and have amortized $0.5 million in the Current Period. Depreciation expense decreased as part of our efforts
to maintain our current fleet of equipment and supplement it as necessary with more economical project specific leased equipment.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The need for working capital for our business
varies due to fluctuations in operating activities and investments in our Contract Capital. The Components of Contract Capital
at June 30, 2017 and 2016 and changes during the Current Quarter and Prior Quarter were as follows (amounts in thousands):</p>

and Joint Ventures </i></b></p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">We participate in various construction
joint ventures 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 is 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 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>

million of construction work to be completed on unconsolidated construction joint venture contracts, of which $39 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 June 30, 2017, 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 provisions under our contracts.</P>

margin: 0pt 0 0"&gt;The purchase price allocation and related amortization periods are based upon preliminary information and are subject to change when additional information concerning final asset and liability valuations is obtained. We have &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; completed our final assessment of the fair value of purchased intangible assets, property and equipment, inventory, tax balances, contingent liabilities, long-term leases or acquired contracts. Our final purchase price allocation &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;result in adjustments to certain assets and liabilities, including the residual amount allocated to goodwill. We have preliminarily assigned an asset value of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$40.0&lt;/div&gt; million for identified intangible assets and have amortized &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.5&lt;/div&gt; million which is included in general and administrative expenses on our statement of operations for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017. &lt;/div&gt;We believe that a majority of the intangible amount will be allocated to customer relationships. A &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10%&lt;/div&gt; change in the valuation of intangible assets would cause a corresponding increase or decrease in the balance of goodwill and annual amortization expense of approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$4.0&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.2&lt;/div&gt; million respectively.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: left; 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;Supplemental Pro Forma Information (Unaudited)&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 24.5pt; margin: 9pt 0 0"&gt;The following unaudited pro forma condensed combined financial information (&amp;#x201c;the pro forma financial information&amp;#x201d;) gives effect to the acquisition of Tealstone by Sterling, accounted for as a business combination using the purchase method of accounting. To give effect to the Tealstone Acquisition for pro forma financial information purposes, Tealstone&amp;#x2019;s commercial historical results were brought to within &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; month of Sterling&amp;#x2019;s interim results for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; month period ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017, &lt;/div&gt;and included the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2017, &lt;/div&gt;respectively. The pro forma financial information reflects the Tealstone Acquisition and related events as if they occurred at the beginning of the period, and gives effect to pro forma events that are: directly attributable to the acquisition, factually supportable, and expected to have a continuing impact on the combined results of Sterling and Tealstone following the acquisition. The pro forma financial information includes adjustments to: (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1&lt;/div&gt;)&amp;nbsp;exclude transaction costs that were included in Sterling&amp;#x2019;s and Tealstone&amp;#x2019;s historical results and are expected to be non-recurring; (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2&lt;/div&gt;)&amp;nbsp;include additional intangibles amortization and net interest expense associated with the Tealstone Acquisition; and (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;3&lt;/div&gt;)&amp;nbsp;include the pro forma results of Tealstone for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; month periods ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017. &lt;/div&gt;This pro forma financial information has been presented for illustrative purposes only and is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; necessarily indicative of the operating results that would have been achieved had the pro forma events taken place on the dates indicated. Further, the pro forma financial information does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; purport to project the future operating results of the combined company following the Tealstone Acquisition.

font-style: italic; font-weight: inherit; font-style: normal;"&gt;$85,000,000&lt;/div&gt; (the &amp;#x201c;Loan&amp;#x201d;) with a maturity date of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 4, 2022, &lt;/div&gt;which replaced the then existing debt facility. The Loan is secured by substantially all of the assets of the Company and its subsidiaries.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;Interest on the Loan is equal to the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt;-, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt;- or &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt;-month London interbank rate, or LIBOR, plus &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;8.75%&lt;/div&gt; per annum on the unpaid principal amount of the Loan, subject to adjustment under certain circumstances. Interest on the Loan is generally payable monthly. There are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; amortized principal payments; however, the Company is required to prepay the Loan, and in certain cases pay a prepayment premium thereon, with proceeds received from the issuances of debt or equity, transfers, events of loss and extraordinary receipts. The Company is required to make an offer quarterly to the lenders to prepay the Loan in an amount equal to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;75%&lt;/div&gt; of its excess cash flow, plus accrued and unpaid interest thereon and a prepayment premium.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;The Loan Agreement contains various covenants that limit, among other things, the Company&amp;#x2019;s ability and certain of its subsidiaries&amp;#x2019; ability to incur certain indebtedness, grant certain liens, merge or consolidate, sell assets, make certain loans, enter into acquisitions, incur capital expenditures, make investments, and pay dividends. In addition, the Company is required to maintain the following principal financial covenants:&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0 0.05in 2pt 0"&gt;&amp;nbsp;&lt;/div&gt;

Current income tax expense or (benefit) represents federal and state taxes based on tax paid or expected to be payable or receivable for the periods shown in the condensed consolidated statements of operations.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;The Company is expecting a current federal liability for alternative minimum tax. The Company &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;incur current state tax liabilities in states in which the Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have sufficient net operating loss carry forwards. A minimal income tax expense was recorded for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017 &lt;/div&gt;and also for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2016. &lt;/div&gt;The effective income tax rate varied from the statutory rate primarily as a result of the change in the valuation allowance, net income attributable to noncontrolling interest owners which is taxable to those owners rather than to the Company, state income taxes and other permanent differences. For interim periods the Company estimates an annual effective tax rate and applies that rate to year-to-date operating results.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;The Company&amp;#x2019;s deferred tax expense or (benefit) reflects the change in deferred tax assets or liabilities.

Based upon this analysis, a full valuation allowance has been applied to our net deferred tax assets as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2016. &lt;/div&gt;Therefore, there has been &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; &lt;/div&gt;change in net deferred taxes for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;As a result of the Company&amp;#x2019;s analysis, management has determined that the Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have any material uncertain tax positions.&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

We expect that revenue generated from our fixed unit price contracts, which represent a significant portion of our total contracts, will continue to be recognized over time utilizing the cost-to-cost measure of progress consistent with our current practice. Therefore, we do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; expect a material impact to the Company&amp;#x2019;s Consolidated Financial Statements related to fixed unit price contracts. We also expect our revenue recognition disclosures to significantly expand due to the new qualitative and quantitative requirements under the standard. The Company is currently determining the impact of the new standard on our lump-sum, cost-plus and other than fixed unit price contracts. Because the standards will impact our business processes, systems and controls, the Company is also developing a comprehensive change management project plan to guide the implementation. &lt;div style="display: inline; font-size: 10pt"&gt;We will adopt the requirements of the new standard effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 1, 2018 &lt;/div&gt;and intend to use the modified retrospective adoption approach, but will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; make a final decision on the adoption method until later in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017.&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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 and joint ventures,&amp;#x201d; respectively.

All significant intercompany accounts and transactions have been eliminated in consolidation. For all years presented, the Company had &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; subsidiaries where its ownership interests were less than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;50%.&lt;/div&gt; Refer to Note &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;4&lt;/div&gt; for further information regarding the Company&amp;#x2019;s Subsidiaries and Joint Ventures with Noncontrolling Owners&amp;#x2019; Interest.&lt;/div&gt; &lt;!-- Field: Page; Sequence: 7 --&gt;   &lt;!-- Field: /Page --&gt; &lt;div style=" font-size: 10pt; text-align: justify; margin: 5pt 0 2pt"&gt;&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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 condensed consolidated statements of operations and as a single line item (&amp;#x201c;Receivables from and equity in construction joint ventures&amp;#x201d;) in the condensed 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;5&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 GAAP, 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 it has a noncontrolling variable interest. Refer to Note &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;6&lt;/div&gt; for further information regarding the Company&amp;#x2019;s consolidated VIE.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"&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 the accompanying condensed consolidated 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, purchase accounting, including intangibles and 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 0.05in 6pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Reclassification&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 2pt 0.05in 2pt 0"&gt;Reclassifications have been made to historical financial data on our condensed consolidated financial statements to conform to our current year presentation.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 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;&lt;div style="display: inline; font-style: italic;"&gt;Heavy Civil Construction&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 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 mechanic&amp;#x2019;s liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners.&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;12&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;36&lt;/div&gt; months to complete. The Company generally provides a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt;-year warranty for workmanship under its contracts when completed. Warranty claims historically have been insignificant.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0pt 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;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 0pt 2pt"&gt;Changes in estimated revenues and gross margin resulted in a net charge of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.8&lt;/div&gt; million and a net charge of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.1&lt;/div&gt; million during the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017, &lt;/div&gt;respectively, included in &amp;#x201c;operating income (loss)&amp;#x201d; on the condensed consolidated statements of operations&lt;div style="display: inline; color: red"&gt;. &lt;/div&gt;Changes in estimated revenues and gross margin resulted in a net gain of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.7&lt;/div&gt; million and a net charge of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.5&lt;/div&gt; million during the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2016, &lt;/div&gt;respectively, included in &amp;#x201c;operating income (loss)&amp;#x201d; on the condensed consolidated statements of operations&lt;div style="display: inline; color: red"&gt;.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0pt 2pt"&gt;Change orders are modifications of an original contract that effectively change the existing provisions of the contract without adding new provisions or terms. Change orders &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;initiate change orders.&lt;/div&gt; &lt;!-- Field: Page; Sequence: 8 --&gt;   &lt;!-- Field: /Page --&gt; &lt;div style=" font-size: 10pt; text-align: justify; margin: 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; yet been agreed upon. Costs associated with unapproved change orders are included in the estimated costs 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;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 0.05in 2pt 0"&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: (i) 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; (ii) Additional costs are caused by circumstances that were unforeseen at the contract date and are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; the result of deficiencies in the contractor&amp;#x2019;s performance; (iii) Costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and (iv) The evidence supporting the claim is objective and verifiable, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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.&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;The Company has projects where we are in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with our customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information has been provided to our customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; reached, legal action will be taken.&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;Based upon our review of the provisions of our contracts, specific costs incurred and other related evidence supporting the unapproved change orders, claims and our entitled unpaid project price, together with the views of the Company&amp;#x2019;s outside claim consultants, we concluded that including the unapproved change order, claim and entitled unpaid project price amounts of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.4&lt;/div&gt; million, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$12.0&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$3.9&lt;/div&gt; million, respectively, at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017, &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$2.2&lt;/div&gt; million, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$9.2&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$3.9&lt;/div&gt; million, respectively, at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2016, &lt;/div&gt;in &amp;#x201c;Costs and estimated earnings in excess of billings on uncompleted contracts&amp;#x201d; on our condensed consolidated balance sheets was in accordance with GAAP. We expect these matters will be resolved without a material adverse effect on our financial statements. However, unapproved change order and claim amounts are subject to negotiations which &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;cause actual results to differ materially from estimated and recorded amounts.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Residential Construction&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;Residential construction revenue and related profit is recognized when construction is completed.

Under the new guidance, an entity is required to perform the following &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt; steps: (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1&lt;/div&gt;) identify the contract(s) with a customer; (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2&lt;/div&gt;) identify the performance obligations in the contract; (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;3&lt;/div&gt;) determine the transaction price; (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;4&lt;/div&gt;) allocate the transaction price to the performance obligations in the contract; and (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;5&lt;/div&gt;) recognize revenue when (or as) the entity satisfies a performance obligation. In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 2015, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;14&lt;/div&gt; which deferred the effective date of ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;09&lt;/div&gt; by &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year.

We expect that revenue generated from our fixed unit price contracts, which represent a significant portion of our total contracts, will continue to be recognized over time utilizing the cost-to-cost measure of progress consistent with our current practice. Therefore, we do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; expect a material impact to the Company&amp;#x2019;s Consolidated Financial Statements related to fixed unit price contracts. We also expect our revenue recognition disclosures to significantly expand due to the new qualitative and quantitative requirements under the standard. The Company is currently determining the impact of the new standard on our lump-sum, cost-plus and other than fixed unit price contracts. Because the standards will impact our business processes, systems and controls, the Company is also developing a comprehensive change management project plan to guide the implementation. &lt;div style="display: inline; font-size: 10pt"&gt;We will adopt the requirements of the new standard effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 1, 2018 &lt;/div&gt;and intend to use the modified retrospective adoption approach, but will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; make a final decision on the adoption method until later in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

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 mechanic&amp;#x2019;s liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners.&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;12&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;36&lt;/div&gt; months to complete. The Company generally provides a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt;-year warranty for workmanship under its contracts when completed. Warranty claims historically have been insignificant.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0pt 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;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 0pt 2pt"&gt;Changes in estimated revenues and gross margin resulted in a net charge of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.8&lt;/div&gt; million and a net charge of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.1&lt;/div&gt; million during the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017, &lt;/div&gt;respectively, included in &amp;#x201c;operating income (loss)&amp;#x201d; on the condensed consolidated statements of operations&lt;div style="display: inline; color: red"&gt;. &lt;/div&gt;Changes in estimated revenues and gross margin resulted in a net gain of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.7&lt;/div&gt; million and a net charge of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.5&lt;/div&gt; million during the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2016, &lt;/div&gt;respectively, included in &amp;#x201c;operating income (loss)&amp;#x201d; on the condensed consolidated statements of operations&lt;div style="display: inline; color: red"&gt;.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0pt 2pt"&gt;Change orders are modifications of an original contract that effectively change the existing provisions of the contract without adding new provisions or terms. Change orders &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;initiate change orders.&lt;/div&gt; &lt;!-- Field: Page; Sequence: 8 --&gt; &lt;!-- Field: /Page --&gt; &lt;div style=" font-size: 10pt; text-align: justify; margin: 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; yet been agreed upon. Costs associated with unapproved change orders are included in the estimated costs 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;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 0.05in 2pt 0"&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: (i) 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; (ii) Additional costs are caused by circumstances that were unforeseen at the contract date and are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; the result of deficiencies in the contractor&amp;#x2019;s performance; (iii) Costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and (iv) The evidence supporting the claim is objective and verifiable, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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.&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;The Company has projects where we are in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with our customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information has been provided to our customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; reached, legal action will be taken.&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;Based upon our review of the provisions of our contracts, specific costs incurred and other related evidence supporting the unapproved change orders, claims and our entitled unpaid project price, together with the views of the Company&amp;#x2019;s outside claim consultants, we concluded that including the unapproved change order, claim and entitled unpaid project price amounts of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.4&lt;/div&gt; million, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$12.0&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$3.9&lt;/div&gt; million, respectively, at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2017, &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$2.2&lt;/div&gt; million, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$9.2&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$3.9&lt;/div&gt; million, respectively, at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2016, &lt;/div&gt;in &amp;#x201c;Costs and estimated earnings in excess of billings on uncompleted contracts&amp;#x201d; on our condensed consolidated balance sheets was in accordance with GAAP. We expect these matters will be resolved without a material adverse effect on our financial statements. However, unapproved change order and claim amounts are subject to negotiations which &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;cause actual results to differ materially from estimated and recorded amounts.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0pt 0.05in 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Residential Construction&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;Residential construction revenue and related profit is recognized when construction is completed.

Based on our review, we have concluded that our operations consist of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; reportable segments, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; operating segments and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; reporting unit components: heavy civil construction and residential construction. 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 the aggregation of heavy civil construction projects and the entire residential construction division when making operating decisions and assessing the Company&amp;#x2019;s overall performance. Furthermore, we considered the differences between the types of work performed in each reporting unit. 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. Projects in our heavy civil construction segment typically last for several years, involve several subtasks and are accounted for using the percentage of completion method. Conversely, our residential construction projects typically consist of a high volume of independent units performed for customers that are billed, paid and accounted for as the individual units are completed. Each job performed in our residential construction segment typically takes less than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; month to complete.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;Segment reporting is aligned based upon the services offered by our &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; operating groups, which represent our reportable segments: Heavy Civil Construction and Residential Construction, as mentioned above. Our chief operating decision maker evaluates the performance of the aforementioned operating groups based upon revenue and income from operations. Each operating group&amp;#x2019;s income from operations reflects corporate costs, allocated based primarily upon revenue.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in;

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, purchase accounting, including intangibles and 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;</us-gaap:UseOfEstimates>

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, purchase accounting, including intangibles and 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 0.05in 6pt 0"><div style="display: inline; font-style: italic;">Reclassification</div></div> <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 2pt 0.05in 2pt 0">Reclassifications have been made to historical financial data on our condensed consolidated financial statements to conform to our current year presentation.</div> <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 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"><div style="display: inline; font-style: italic;">Heavy Civil Construction</div></div> <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company engages in various types of heavy civil construction projects principally for public (government) owners.

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.

Under the new guidance, an entity is required to perform the following <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">five</div> steps: (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">1</div>) identify the contract(s) with a customer; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2</div>) identify the performance obligations in the contract; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">3</div>) determine the transaction price; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">4</div>) allocate the transaction price to the performance obligations in the contract; and (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">5</div>) recognize revenue when (or as) the entity satisfies a performance obligation. In <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> August 2015, </div>the FASB issued ASU <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2015</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">14</div> which deferred the effective date of ASU <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2014</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">09</div> by <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">one</div> year.

We expect that revenue generated from our fixed unit price contracts, which represent a significant portion of our total contracts, will continue to be recognized over time utilizing the cost-to-cost measure of progress consistent with our current practice. Therefore, we do <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> expect a material impact to the Company&#x2019;s Consolidated Financial Statements related to fixed unit price contracts. We also expect our revenue recognition disclosures to significantly expand due to the new qualitative and quantitative requirements under the standard. The Company is currently determining the impact of the new standard on our lump-sum, cost-plus and other than fixed unit price contracts. Because the standards will impact our business processes, systems and controls, the Company is also developing a comprehensive change management project plan to guide the implementation. <div style="display: inline; font-size: 10pt">We will adopt the requirements of the new standard effective <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> January 1, 2018 </div>and intend to use the modified retrospective adoption approach, but will <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> make a final decision on the adoption method until later in <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2017.</div></div></div></div><span></span>

Based on our review, we have concluded that our operations consist of <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">two</div> reportable segments, <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">two</div> operating segments and <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">two</div> reporting unit components: heavy civil construction and residential construction. In making this determination, the Company considered the discrete financial information used by our Chief Operating Decision Maker (&#x201c;CODM&#x201d;). Based on this approach, the Company noted that the CODM organizes, evaluates and manages the financial information around the aggregation of heavy civil construction projects and the entire residential construction division when making operating decisions and assessing the Company&#x2019;s overall performance. Furthermore, we considered the differences between the types of work performed in each reporting unit. 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. Projects in our heavy civil construction segment typically last for several years, involve several subtasks and are accounted for using the percentage of completion method. Conversely, our residential construction projects typically consist of a high volume of independent units performed for customers that are billed, paid and accounted for as the individual units are completed. Each job performed in our residential construction segment typically takes less than <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">one</div> month to complete.</div> <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Segment reporting is aligned based upon the services offered by our <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">two</div> operating groups, which represent our reportable segments: Heavy Civil Construction and Residential Construction, as mentioned above.

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

Costs associated with unapproved change orders are included in the estimated costs to complete the contracts and are treated as project costs as incurred.

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: (i) 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; (ii) Additional costs are caused by circumstances that were unforeseen at the contract date and are <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> the result of deficiencies in the contractor&#x2019;s performance; (iii) Costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and (iv) The evidence supporting the claim is objective and verifiable, <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> based on management&#x2019;s feel for the situation or on unsupported representations.

Under the new guidance, an entity is required to perform the following <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">five</div> steps: (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">1</div>) identify the contract(s) with a customer; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2</div>) identify the performance obligations in the contract; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">3</div>) determine the transaction price; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">4</div>) allocate the transaction price to the performance obligations in the contract; and (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">5</div>) recognize revenue when (or as) the entity satisfies a performance obligation. In <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> August 2015, </div>the FASB issued ASU <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2015</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">14</div> which deferred the effective date of ASU <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2014</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">09</div> by <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">one</div> year.

We expect that revenue generated from our fixed unit price contracts, which represent a significant portion of our total contracts, will continue to be recognized over time utilizing the cost-to-cost measure of progress consistent with our current practice. Therefore, we do <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> expect a material impact to the Company&#x2019;s Consolidated Financial Statements related to fixed unit price contracts. We also expect our revenue recognition disclosures to significantly expand due to the new qualitative and quantitative requirements under the standard. The Company is currently determining the impact of the new standard on our lump-sum, cost-plus and other than fixed unit price contracts. Because the standards will impact our business processes, systems and controls, the Company is also developing a comprehensive change management project plan to guide the implementation. <div style="display: inline; font-size: 10pt">We will adopt the requirements of the new standard effective <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> January 1, 2018 </div>and intend to use the modified retrospective adoption approach, but will <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> make a final decision on the adoption method until later in <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2017.</div></div></div></div></div></div></div></div><span></span>
