The reinforced concrete foundation slab supporting a structure's entire load. Subcontractors doing civil or concrete work often mobilise early to complete basemat pours before other trades arrive. Scheduling and cure time directly affect downstream scopes.
Basemat
Related Terms
Heavy Civil
IndustryLarge-scale infrastructure construction involving earthworks, bridges, roads, and foundations. Subcontractors in this sector typically supply specialised equipment, civil crews, or concrete services. Contracts are often high-value but require significant bonding and insurance capacity.
Cable-Stayed
IndustryA bridge or structure supported by cables running directly from towers to the deck. Subcontractors working on these structures face specialised rigging, inspection, and access challenges. Confirm tower and cable access requirements before mobilising crew and equipment.
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.
Carbon Dioxide Treater
IndustryA vessel or system used on oil and gas sites to remove CO2 (Carbon Dioxide) from produced gas or water streams. Subcontractors are often hired to install, service, and inspect these units. Proper handling requires H2S and pressure safety training.
Voluntary Cuts
IndustryAgreed reductions in oil production by member nations, typically OPEC (Organization of the Petroleum Exporting Countries) members, to stabilise prices. For subcontractors, these cuts often trigger project deferrals, reduced scope, and slower mobilisation schedules. Budget freezes from operators frequently follow, directly impacting field service award timelines.
Wellpad
IndustryA prepared, levelled site where one or more oil or gas wells are drilled and completed. Subcontractors often mobilise to a wellpad for multi-well scopes, making it a key unit for planning labour and equipment. Pad size and well count directly affect job duration and invoicing cycles.
