PMC (Project Management Contractor)

On-location support work performed at an active drill site, including safety watch, equipment operation, and logistics. Subcontractors are typically mobilised on short notice and paid on a day-rate basis. Scope can shift quickly, so clear change-order processes are essential.

A technical specification document outlining the dimensions, grade, and tolerances for sucker rods used in artificial lift systems. Subcontractors must match rod spec requirements exactly before mobilising equipment or labour. Non-compliance can result in rejected work and withheld payment.

The pipelines, power lines, roads, and utility networks that move resources from production sites to end users. Subcontractors are frequently hired to build, inspect, or maintain these systems. Work can span remote corridors, requiring careful logistical and safety planning.

A postponement caused by unfinished grid or pipeline tie-in work that prevents a facility from going live. For subcontractors, it often means demobilisation holds, scope gaps, or standby costs with no clear end date. Document all waiting time carefully to support delay claims or change orders.

Preparatory ground-level work completed before main construction begins, including grading, excavation, and utility rough-ins. Subcontractors are often scoped for sitework as a standalone package. Delays in sitework directly impact downstream trade access and schedule.

A large lifting crane mounted on tracked undercarriage, used for heavy lifts on unstable or soft ground at oil and gas and construction sites. Subcontractors often source these through specialised rigging firms on a day-rate or project basis. Confirm ground-bearing capacity and operator certifications before mobilising.
