Work performed on-site without removing equipment or materials from their installed position. Subcontractors are often mobilised specifically for in-situ repairs, inspections, or testing. Scope and billing should clearly reflect the fixed work location.
In-Situ
Related Terms
All of the Above (energy Policy)
IndustryA government strategy supporting oil, gas, renewables, and nuclear simultaneously rather than picking one energy source. For subcontractors, it means diversified project opportunities across multiple energy sectors. Crews and companies that can work across sectors gain a competitive advantage in bidding.
Pjm (pennsylvania-New Jersey-Maryland) Interconnection Queue
IndustryA waiting list managed by PJM for new power generation and transmission projects seeking grid connection approval. Subcontractors use it to track upcoming infrastructure builds and time their bids accordingly. Long queue backlogs signal sustained field work demand in the PJM service territory.
AGC (Associated General Contractors of America)
IndustryA U.S. trade association representing general contractors in construction. Subcontractors working with AGC members often encounter standardised contract templates and safety compliance expectations tied to membership. Knowing AGC standards helps subs align bids and prequalification documents with GC requirements.
Candu (canadian Deuterium Uranium) Reactor
IndustryA Canadian-designed nuclear reactor that uses heavy water as a moderator and coolant. Subcontractors working on maintenance or upgrades face strict nuclear regulatory compliance and specialised certification requirements. Expect rigorous site access controls, radiation safety training, and detailed documentation standards.
Open Season
IndustryA formal period when a pipeline or facility operator accepts capacity commitments from potential shippers or users. For subcontractors, it signals upcoming project activity and a chance to position for related field service work. Winning commitments during open season often triggers procurement and mobilisation timelines.
CCGT (Combined-cycle Gas Turbine)
IndustryA power generation system that captures waste heat from a gas turbine to drive a secondary steam turbine, boosting efficiency. Subcontractors often support CCGT plants during scheduled outages, commissioning, and maintenance shutdowns. Work typically requires specialised turbine, piping, and instrumentation trades.
