Segment Reporting [Abstract]  
Segment Information Segment Information
In fiscal 2020, we operated our business through four reportable segments: Electrical Infrastructure; Oil Gas & Chemical; Storage Solutions; and Industrial.
The Electrical Infrastructure segment consists of power delivery services provided to investor owned utilities, including construction of new substations, upgrades of existing substations, short-run transmission line installations, distribution upgrades and maintenance, as well as emergency and storm restoration services. We also provide construction and maintenance services to a variety of power generation facilities, such as combined cycle plants and other natural gas fired power stations.
The Oil Gas & Chemical segment serves customers primarily in the downstream and midstream petroleum industries who are engaged in refining crude oil and processing, fractionating, and marketing of natural gas and natural gas liquids. We also perform work in the petrochemical, and sulfur extraction, recovery and processing markets. Our services include plant maintenance, turnarounds, engineering and capital construction. We also offer industrial cleaning services, including hydro-blasting, hydro-excavating, advanced chemical cleaning and vacuum services.
The Storage Solutions segment consists of work related to aboveground storage tanks ("AST") and terminals. Also included in this segment are cryogenic and other specialty storage tanks and terminals including liquefied natural gas, liquid nitrogen/liquid oxygen, liquid petroleum and other specialty vessels such as spheres as well as marine structures and truck and rail loading/offloading facilities. Our services include engineering, fabrication and construction, and maintenance and repair, which includes planned and emergency services for both tanks and full terminals. 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 Process and Industrial Facilities segment includes engineering, maintenance, turnarounds and capital projects for the refining, chemical and petrochemical industries; midstream natural gas processing; other industrial processing facilities including biofuels, fertilizer, and sulfur; mining and minerals infrastructure; and thermal vacuum chambers. This segment is similar to the former Oil Gas & Chemical segment described above, but includes mining and minerals, thermal vacuum chambers, and work in other industrial facilities which were historically reported in the Industrial segment.
Due to changing markets facing our clients and to better align the financial reporting of the Company with our long-term strategic growth areas, we are changing our reporting segments. Beginning in fiscal 2021, the Company’s financial results will be reported under the following three segments: Utility and Power Infrastructure; Process and Industrial Facilities; and Storage and Terminal Solutions. The services provided by each of these segments is described below.
The Utility and Power Infrastructure segment includes services provided in power delivery and power generation, as well as natural gas utility peak shaving. This segment is similar to the former Electrical Infrastructure segment described above, but includes natural gas utility peak shaving facilities that have been historically reported in the Storage Solutions segment.

The Process and Industrial Facilities segment includes engineering, maintenance, turnarounds and capital projects for the refining, chemical and petrochemical industries; midstream natural gas processing; other industrial processing facilities including biofuels, fertilizer, and sulfur; mining and minerals infrastructure; and thermal vacuum chambers. This segment is similar to the former Oil Gas & Chemical segment described above, but includes mining and minerals as well as thermal vacuum chambers, which were historically reported in the Industrial segment.
The Storage and Terminal Solutions segment includes engineering, construction, maintenance and repair for aboveground storage tanks and terminals; LNG facilities for import/export fueling and bunkering; NGL and other specialty vessels; aboveground storage tank products; and other renewable energy storage and terminal solutions. This segment is similar to the former Storage Solutions segment described above, but does not include the natural gas utility peak shaving facilities, which will be reported as part of the Utility and Power Infrastructure segment.
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, goodwill and other intangible assets.
