Large-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.

WCSB (Western Canadian Sedimentary Basin)
IndustryA vast sedimentary basin spanning BC, Alberta, Saskatchewan, and Manitoba that hosts Canada's largest oil and gas reserves. It is the primary operating region for most Canadian upstream field service subcontractors. Work here includes conventional drilling, oil sands operations, and pipeline construction.
Surface Milling
IndustryA machining process that removes material from a flat surface to restore or achieve precise tolerances on equipment components. Subcontractors are often mobilised to perform surface milling on wellheads, flanges, or structural steel on-site. Proper equipment certifications and dimensional records are typically required for handover documentation.
TEU (Twenty-foot Equivalent Unit)
IndustryA standard shipping container measurement used to calculate freight capacity and logistics costs on large projects. One TEU equals one standard 20-foot container. Subcontractors mobilising equipment or materials to remote sites often quote and invoice freight in TEUs.
Combined Cycle
IndustryA power generation setup where waste heat from a gas turbine is reused to produce additional electricity via a steam turbine. Subcontractors working these facilities must be prepared for more complex systems and stricter safety protocols. Maintenance scopes are typically broader, covering both turbine types.
IFB (Invitation for Bids)
IndustryA formal document issued by an operator or prime contractor soliciting fixed-price bids for a defined scope of work. Subcontractors must submit pricing by a set deadline, with contracts typically awarded to the lowest qualified bidder. Review the technical specs and site conditions carefully before submitting your number.
PAC (Polyanionic Cellulose)
IndustryA water-soluble polymer additive used in drilling fluids to control fluid loss and stabilise boreholes. Subcontractors handling mud systems must store and mix PAC carefully, as improper use affects drilling performance. It is commonly specified in drilling programmes, so field crews should follow the mud engineer's exact dosage instructions.
