Preferred Vendor Status
IndustryA designation granted by an operator or prime contractor that puts your company on an approved list for recurring work. It typically means faster bid access, less vetting paperwork, and priority callouts. Earning it usually requires meeting set safety, insurance, and performance benchmarks.
Legacy Site
IndustryAn older facility or work location operating on outdated infrastructure, systems, or equipment. Subcontractors often face non-standard conditions, ageing assets, and extra compliance requirements on these sites. Mobilisation and scoping costs can be higher due to undocumented or deteriorated site conditions.
Esker
IndustryA long, winding ridge of sand and gravel deposited by glacial meltwater. Eskers create uneven, unstable terrain that affects equipment access, ground disturbance permits, and site planning for subcontractors.
Shaft Sinking
IndustryThe 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.
Building Electrification
IndustryThe process of replacing fossil fuel-based systems in buildings with electric alternatives, such as heat pumps and induction equipment. For subcontractors, it drives demand for electrical, HVAC, and mechanical retrofits. Crews must often hold updated certifications to work on high-voltage systems and EV (Electric Vehicle) charging infrastructure.
PPA (Power Purchase Agreement)
IndustryA long-term contract where a buyer agrees to purchase electricity from a generator at a fixed price. For subcontractors, PPAs on large sites can affect whether temporary or permanent power infrastructure is in scope. Understanding site power arrangements helps clarify mobilisation costs and equipment requirements.
