Segment Reporting [Abstract]

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, nuclear facilities, coal fired power stations, and renewable energy installations.

The Oil Gas & Chemical segment includes our traditional turnaround activities, plant maintenance services and construction in the downstream petroleum industry. Another key offering is industrial cleaning services, which include hydroblasting, hydroexcavating, chemical cleaning and vacuum services. We also perform work in the renewable energy, industrial and natural gas, gas processing and compression, and upstream petroleum markets.

The Storage Solutions segment includes new construction of, as well as planned and emergency maintenance services for, crude and refined products aboveground storage tanks. 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, the Storage Solutions segment includes balance of plant work in storage terminals and tank farms.

The Industrial segment includes work in the mining and minerals industry, bulk material handling, thermal vacuum chambers, fertilizer production facilities, as well as work for clients in other industrial and manufacturing markets.

The chief operating decision maker evaluates performance and allocates resources based primarily on operating income. The results of each operating segment include an allocation of corporate costs. 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 and eliminated in consolidation; 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, goodwill and other intangible assets.
