Preliminary site preparation activities awarded before a project's main contract is finalised. For subcontractors, this means mobilising early—often under a letter of intent—to handle clearing, grading, or utility work. Scope and payment terms can be limited, so review your agreement carefully before committing resources.

Q&T (Quench and Tempering)
IndustryA two-stage heat treatment process that hardens steel pipe and structural components used in oil and gas and construction applications. The steel is rapidly cooled (quenched), then reheated (tempered) to improve toughness and reduce brittleness. Subcontractors working with Q&T-rated steel must follow strict welding procedures, as improper heat input can compromise the material's mechanical properties.
Integrity Testing
IndustryPressure or leak testing performed on pipelines, vessels, or equipment to confirm structural soundness before operations begin. Subcontractors are often scoped specifically for this work as a standalone service. Clients may require certified personnel and documented results before approving system start-up.
Dispatchable Power
IndustryPower generation that can be turned on or off on demand, unlike solar or wind. For field crews, this means reliable site power for tools, lighting, and equipment regardless of weather. Generators and diesel units are common dispatchable power sources on remote job sites.
Owner-Formed Alliance
IndustryA long-term agreement where an owner operator selects a fixed group of contractors to handle ongoing work. Subcontractors inside the alliance get preferred access to scopes but must meet strict performance and pricing benchmarks. Those outside the alliance are often locked out of bidding entirely.
Scissor Lift
IndustryA mobile elevated work platform that uses a folding metal support structure to raise workers and materials vertically. Commonly used by subcontractors for maintenance, installations, and inspections at height on industrial sites. Operators typically require documented training and a valid operator certification before use.
Dynamic Line Rating
IndustryA real-time method of calculating the maximum safe current capacity of a power line based on actual weather and load conditions. Unlike fixed ratings, it allows more power to flow when conditions permit. Field crews may encounter adjusted work protocols near energised lines as ratings shift throughout the day.
