Industry Glossary Term

Self-Supply

When a subcontractor provides their own tools, equipment, or materials rather than relying on the prime contractor or client. This shifts procurement responsibility — and often cost risk — directly to your company. Pricing your bids correctly to recover these costs is critical.

Related Terms

ERAS (Expedited Resource Addition Study)

Industry

A utility or pipeline operator's fast-tracked assessment to connect new energy infrastructure to the grid or network. For subcontractors, an approved ERAS often signals upcoming mobilisation opportunities and tight project timelines. Winning work tied to an ERAS typically means compressed schedules and rapid crew deployment.

Chokepoint

Industry

A stage in a project where workflow bottlenecks, delaying downstream tasks and crew productivity. For subcontractors, chokepoints often occur at inspection holds, permit approvals, or material deliveries. Identifying them early helps protect schedule and avoid costly standby time.

Cold-Milled Asphalt

Industry

Reclaimed pavement material produced by grinding existing asphalt surfaces without heat. Subcontractors encounter it during road restoration work on well pads, pipeline rights-of-way, and industrial sites. It is commonly reused as base material, reducing disposal costs and material haul-off requirements.

Well Intervention

Industry

Any post-completion operation performed on a producing well to restore or improve output. Subcontractors are often mobilised for wireline, coiled tubing, or pump work during these campaigns. Scope can change quickly, so confirm work orders before committing crew and equipment.

Carbon Capture

Industry

The process of collecting and storing CO2 emissions from industrial sites before they reach the atmosphere. For subcontractors, it means growing work opportunities in facility retrofits, pipeline installation, and compression equipment servicing. Familiarity with CCS (Carbon Capture and Storage) infrastructure is increasingly expected on energy transition projects.

Co2 Pipeline

Industry

A pressurised pipeline system that transports carbon dioxide, typically for carbon capture and storage (CCS) projects or enhanced oil recovery (EOR). Subcontractors may be engaged for construction, inspection, or maintenance under strict pressure and corrosion control requirements. Specialised welding certifications and material handling protocols are commonly required for this work.
