Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Transmission Upgrades

Large-scale projects to expand or modernise pipeline or power transmission infrastructure. For subcontractors, these generate significant work in welding, civil prep, and equipment installation. Scopes are often phased, requiring flexible crew deployment and quick mobilisation.

Related Terms

Capital Maintenance

Industry

Planned work that restores or extends the life of major assets, such as facilities or equipment. For subcontractors, these projects are typically larger in scope and budget than routine maintenance. They often require formal tendering, detailed scopes of work, and milestone-based billing.

Distribution System

Industry

A network of pipelines, valves, and infrastructure that moves oil, gas, or utilities from a main supply point to end users. Subcontractors are often hired to install, inspect, or maintain these systems. Work scope can include trenching, pipe fitting, and pressure testing across large service areas.

Epc (engineering, Procurement, and Construction) Contractor

Industry

A company hired to deliver a project from design through build, acting as the main contractor above subcontractors. As a subcontractor, your client and contract holder is typically the EPC, not the asset owner. They control scope, scheduling, and invoice approval on site.

Dekatherm

Industry

A unit of energy equal to 10 therms or roughly one million BTUs, used to measure and price natural gas volumes. Subcontractors working on gas facilities or pipelines will encounter this unit in contracts and billing documents. Knowing the conversion helps you verify measurement and invoicing accuracy on natural gas projects.

Spoil Pile

Industry

Excavated soil, rock, or debris removed during trenching or grading and stockpiled on-site. Subcontractors are often responsible for its placement, management, and disposal per site plans. Improper handling can trigger environmental compliance issues and project delays.

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.
