The prime contractor hired by an owner to manage a project, responsible for awarding and overseeing subcontracts. As a sub, your contract, invoicing, and site access typically flow through the GC. They control your payment terms and schedule, making them your primary business relationship on site.
GC (General Contractor)
Related Terms
Self-Supply
IndustryWhen 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.
Battery
IndustryA centralised surface facility where oil and gas from multiple wells is gathered, measured, and processed. Subcontractors frequently mobilise to battery sites for maintenance, instrumentation, and civil work. Knowing the battery layout helps crews plan access, logistics, and safe work zones.
Caustic Service
IndustryWork involving equipment or piping that handles highly alkaline chemicals, such as sodium hydroxide. Subcontractors must use compatible materials and certified personnel to avoid rapid corrosion and serious chemical burns. Specialised PPE and handling procedures are typically required by the client's safety plan.
Subcontractor
IndustryA company hired by a general contractor or directly by an operator to perform a specific portion of work. Subcontractors often specialize in particular services or trades.
Crawler Crane
IndustryA 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.
Pipeline Tie-in
IndustryA pipeline tie-in is the physical connection of a new pipeline section to an existing live system. For subcontractors, tie-in work often requires hot-tap certified crews and strict isolation procedures. Scheduling is critical, as tie-ins typically involve planned shutdowns with tight production windows.
