Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

BIM (Building Information Modelling)

A shared 3D digital model of a construction project that contains structural, mechanical, and site data. Subcontractors use it to coordinate work sequences, avoid clashes with other trades, and verify installation specs before mobilising. Access to the BIM model is often required before entering a worksite.

Related Terms

Tank Farm

Industry

A designated site containing multiple large storage tanks for oil, gas, or chemicals. Subcontractors frequently perform inspection, maintenance, and cleaning work at these facilities. Access permits and confined space certifications are typically required on site.

Combined-Cycle Gas Plant

Industry

A power generation facility that uses both gas turbines and steam turbines to maximise efficiency. For subcontractors, these sites involve complex, multi-discipline scopes across mechanical, electrical, and instrumentation trades. Outage and commissioning work is highly scheduled, requiring precise crew coordination and fast mobilisation.

Development Sanction

Industry

The formal approval by an operator or project owner to proceed with full-scale field development. For subcontractors, it signals that major contracts, mobilisation, and field work are imminent. It marks the point where scopes of work move from planning to active procurement.

IEA (International Energy Agency)

Industry

An intergovernmental organisation that publishes global energy outlooks and demand forecasts, which subcontractors and field service companies use to anticipate shifts in upstream and downstream activity levels that may affect project pipelines and contract opportunities.

PCP (Progressive Cavity Pump)

Industry

A rotary pump used in oil and gas production to lift heavy or viscous fluids from wellbores. Subcontractors are frequently hired for PCP installation, maintenance, and rod-string servicing. Familiarity with drive heads, stators, and rotors is essential for field technicians working these jobs.

Surface Miner

Industry

A large self-propelled machine that cuts, crushes, and loads material in a single pass without blasting. Subcontractors operating surface miners must hold specialised equipment certifications and follow strict site safety protocols. Common in oil sands and open-pit construction projects across Western Canada.
