The process of excavating a vertical or near-vertical tunnel from surface down to an underground work area. Subcontractors are often engaged for specialised tasks like lining, hoisting, or ground support during this phase. It is common in mining, utility, and heavy civil construction projects.

Remediation
IndustryThe cleanup and restoration of contaminated soil, water, or sites to meet regulatory standards. Subcontractors are often hired specifically for remediation scopes on legacy sites or post-incident cleanup. Work is heavily documented and subject to environmental compliance sign-off.
Pump Station
IndustryA facility that moves oil, gas, or water through a pipeline using mechanical pumps. Subcontractors are frequently mobilised to pump stations for maintenance, inspection, and equipment servicing work. These sites often require specific safety certifications and site orientations before work begins.
Cementing
IndustryThe process of pumping cement slurry into a wellbore to seal the casing and isolate formation zones. Subcontractors may be hired to provide cementing crews, pumping equipment, or bulk material handling. It is a critical well integrity step with strict regulatory and operator specifications.
SMR (Small Modular Reactor)
IndustryA compact, factory-built nuclear power unit used to generate on-site electricity for remote industrial facilities and resource projects. For subcontractors, SMR sites represent emerging work in civil, electrical, and mechanical trades. Expect strict federal nuclear safety compliance requirements affecting worker certifications and site access.
Stockpoint
IndustryA designated location where materials, parts, or equipment are staged for quick deployment to active job sites. Subcontractors often draw inventory from a client's stockpoint rather than sourcing independently. Knowing stockpoint locations reduces mobilisation delays and simplifies cost tracking.
Surface Miner
IndustryA large self-propelled machine that cuts, crushes, and loads material in a single pass without blasting. Subcontractors operating surface miners must hold specialised equipment certifications and follow strict site safety protocols. Common in oil sands and open-pit construction projects across Western Canada.
