A facility that converts high-voltage electrical power to usable levels for a job site or facility. Subcontractors in construction and oil & gas often work in, around, or on behalf of substations. Strict access controls and electrical safety certifications are typically required.
Substation
Related Terms
Utility-Scale Storage
IndustryLarge battery or energy storage systems that supply power to grids or remote job sites. For subcontractors, these projects involve specialised electrical, civil, and commissioning crews. Work often includes foundation pours, equipment installation, and grid tie-in under strict utility standards.
Pigging
IndustryThe process of running a device called a pig through a pipeline to clean, inspect, or displace fluids. Subcontractors are often hired to provide pig launcher and receiver equipment, operators, and associated support services. Pigging scopes can range from routine maintenance runs to complex inline inspection campaigns.
Mutual Waiver of Consequential Damages
IndustryA contract clause where both parties agree not to sue each other for indirect losses like lost profits or project delays. For subcontractors, this limits your liability if your work causes a costly shutdown. It also protects you from outsized claims that far exceed your contract value.
Long-Span Structural Systems
IndustryStructural frameworks that cover large distances without intermediate supports, such as trusses, arches, or space frames. Subcontractors encounter these in industrial buildings, processing facilities, and modular plant construction. Work in these areas often requires specialised rigging, elevated access planning, and load-path awareness.
Berth
IndustryA designated docking space where vessels load or offload equipment, materials, and crew. Subcontractors must coordinate mobilisation schedules around berth availability to avoid costly delays. Port congestion can directly impact your invoicing milestones and crew rotations.
PWHT (Post-weld Heat Treatment)
IndustryA controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.
