Turnaround

The legal ownership of subsurface resources like oil, gas, and minerals on a property. Subcontractors work under operators who hold mineral rights, so understanding this ownership structure clarifies who controls site access and project authorisation. Disputes over mineral estates can halt work orders without warning.

A crossing where a road, pipeline, or utility passes over or under another route using a bridge or culvert. Subcontractors must account for grade separations when planning equipment moves and material hauls. Permits and escort requirements often apply when loads approach clearance limits.

The regulated process of permanently closing a well or facility at end-of-life. Subcontractors are often hired for plugging, reclamation, and site cleanup scopes. Abandonment projects can be steady work but require strict compliance with provincial regulations.

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.

Adding a parallel pipeline segment alongside an existing line to increase flow capacity. For subcontractors, it means mobilising crews and equipment for a new build tied into an active system. Expect phased work scopes, tie-in shutdowns, and strict coordination with the operator.

A natural gas liquid (NGL) mixture containing propane, butane, and heavier hydrocarbons separated during processing. Subcontractors working at gas plants or fractionation facilities will handle, transport, or maintain equipment tied to this product stream. Understanding its composition helps crews follow correct handling, storage, and safety protocols on site.
