A project where the owner acts as their own general contractor, hiring subcontractors directly rather than through a prime contractor. For field service companies, this often means faster access to work but requires closer coordination with the owner. Payment terms and scope changes are negotiated directly, so clear contracts are essential.
Self-Build
Related Terms
Crane Mats
IndustryLarge interlocked timber or composite panels placed under crane outriggers to distribute load on soft or unstable ground. Subcontractors often supply, transport, and install them as part of site prep scopes. Rental and mobilisation costs should be clearly itemised in your quote.
Clastic Reservoir
IndustryA rock formation made of compacted sediment fragments — like sandstone or conglomerate — that holds oil or gas. Most drilling and completions work in Western Canada targets clastic reservoirs. Knowing the formation type helps crews anticipate ground conditions and equipment requirements.
Lease Road
IndustryA temporary or permanent access road built to service an oil and gas lease or well site. Subcontractors are often responsible for maintaining or mobilising equipment over these roads. Road conditions directly affect trucking rates, equipment wear, and scheduling.
CMMS (Computerized Maintenance Management System)
IndustrySoftware used to schedule, track, and document equipment maintenance and work orders on job sites. Subcontractors often must log completed maintenance tasks directly into a client's CMMS. Accurate entries protect you during audits and support invoicing for billable maintenance work.
AFE (Authorization for Expenditure)
IndustryA budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.
SAGD (Steam Assisted Gravity Drainage)
IndustryA heavy oil extraction method using paired horizontal wells where steam is injected into the upper well to heat bitumen, allowing it to drain by gravity to the lower production well. Creates specialized maintenance and service opportunities for subcontractors in steam generation equipment, wellhead systems, and pipeline infrastructure at oil sands operations.
