Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Modular Construction

A build method where structures are assembled from prefabricated units manufactured offsite, then transported and installed on location. Subcontractors are often scoped for site prep, mechanical tie-ins, or installation crews rather than full builds. Work tends to come in concentrated, short-duration packages tied to delivery schedules.

Related Terms

Q&T (Quench and Tempering)

Industry

A two-stage heat treatment process that hardens steel pipe and structural components used in oil and gas and construction applications. The steel is rapidly cooled (quenched), then reheated (tempered) to improve toughness and reduce brittleness. Subcontractors working with Q&T-rated steel must follow strict welding procedures, as improper heat input can compromise the material's mechanical properties.

Modular Water Storage

Industry

Portable, stackable tank systems used on remote job sites to store potable, process, or wastewater. Subcontractors deploy them quickly without permanent infrastructure. Common on pipeline, camp, and frac support contracts.

Switchgear

Industry

Electrical equipment used to control, protect, and isolate power systems on job sites. Subcontractors working near switchgear must follow strict lockout/tagout procedures. Installation and maintenance work often requires certified electricians and site-specific safety permits.

ABC (Associated Builders and Contractors)

Industry

A U.S. trade association representing merit-shop contractors in construction and industrial sectors. Subcontractors use ABC membership for training resources, safety programmes, and industry networking. Membership can also signal credibility when bidding on open-shop projects.

JETI (Jobs, Energy, Technology and Innovation)

Industry

A federal Canadian government initiative supporting energy sector growth through workforce development and clean technology investment. For subcontractors, it signals funding opportunities and contract activity tied to energy transition projects. Companies aligned with JETI priorities may access grants or preferred procurement in oil, gas, and construction.

Below-Grade

Industry

Any work or structure located below the finished ground surface, such as buried pipelines, foundations, or conduits. Subcontractors must account for added costs like shoring, dewatering, and confined space compliance. Scope changes below-grade often trigger change orders due to unforeseen soil or utility conditions.
