The ability to move equipment or materials directly via navigable waterways to a project site. For subcontractors, it affects logistics planning, mobilisation costs, and marine transport requirements. Sites with tidewater access often allow heavier loads that road or rail cannot support.
Tidewater Access
Related Terms
Commercial Operations
IndustryThe point when a facility or project officially begins generating revenue and is fully handed over from construction to production. For subcontractors, this milestone often triggers final billing, contract closeout, and demobilisation. Work orders and scopes tied to commissioning typically end at this date.
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.
C3+ Stream
IndustryA natural gas liquid (NGL) mixture containing propane, butane, and heavier hydrocarbons separated during processing. Subcontractors working at gas plants or fractionation facilities will handle, transport, or maintain equipment tied to this product stream. Understanding its composition helps crews follow correct handling, storage, and safety protocols on site.
Sitework
IndustryPreparatory ground-level work completed before main construction begins, including grading, excavation, and utility rough-ins. Subcontractors are often scoped for sitework as a standalone package. Delays in sitework directly impact downstream trade access and schedule.
Instrumentation
IndustryThe installation, calibration, and maintenance of measurement and control devices such as gauges, transmitters, and sensors. Subcontractors are often scoped specifically for instrumentation work, requiring certified trades and precise documentation. It is a common standalone discipline on large oil and gas and industrial construction projects.
Proponent
IndustryThe company or entity proposing and owning a project, such as an operator or developer. As a subcontractor, the proponent is often the ultimate client driving project requirements and approvals. Understanding who the proponent is helps clarify scope expectations and contract obligations.
