Segment Information
Segment Information
We operate our business through four reportable segments: Electrical Infrastructure, Oil Gas & Chemical, Storage Solutions, and Industrial.
The Electrical Infrastructure segment primarily encompasses high voltage services to investor owned utilities, including construction of new substations, upgrades of existing substations, short-run transmission line installations, distribution upgrades and maintenance, and storm restoration services. We also provide construction and maintenance services to a variety of power generation facilities, such as combined cycle plants, natural gas fired power stations, and renewable energy installations.
The Oil Gas & Chemical segment includes turnaround activities, plant maintenance, engineering and construction in the downstream and midstream petroleum industries. Our customers in these industries are engaged in refining crude oil and processing, fractionating, and marketing of natural gas and natural gas liquids. Another key offering is industrial cleaning services, which include hydroblasting, hydroexcavating, chemical cleaning and vacuum services. We also perform work in the petrochemical, upstream petroleum, and sulfur extraction, recovery and processing markets.
The Storage Solutions segment includes new construction of crude and refined products aboveground storage tanks (“ASTs”), as well as planned and emergency maintenance services. The Storage Solutions segment also includes balance of plant work in storage terminals and tank farms. Also included in the Storage Solutions segment is work related to specialty storage tanks, including liquefied natural gas (“LNG”), liquid nitrogen/liquid oxygen (“LIN/LOX”), liquid petroleum (“LPG”) tanks and other specialty vessels, including spheres. Finally, we offer AST products, including geodesic domes, aluminum internal floating roofs, floating suction and skimmer systems, roof drain systems and floating roof seals.
The Industrial segment primarily includes construction and maintenance work in the iron and steel, mining and minerals, and agricultural industries. Our work in the mining and minerals industry is primarily for customers engaged in the extraction of copper. Our work in the agricultural industry includes the engineering and design of grain silos, docks and handling systems; the design of control system automation and materials handling for the food industry; and engineering, construction, process design and balance of plant work for fertilizer production facilities. We also perform work in bulk material handling, thermal vacuum chambers, and other industrial markets.
The Company evaluates performance and allocates resources based on operating income. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Intersegment sales and transfers are recorded at cost; therefore, no intercompany profit or loss is recognized.
Segment assets consist primarily of accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, property, plant and equipment and goodwill.
