The 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.

Wellsite Services
IndustryOn-location support work performed at an active drill site, including safety watch, equipment operation, and logistics. Subcontractors are typically mobilised on short notice and paid on a day-rate basis. Scope can shift quickly, so clear change-order processes are essential.
Call-Out (call-Out Activity)
IndustryA single, unplanned service request dispatched to a subcontractor or field technician outside of scheduled work. Each call-out is typically logged as a discrete billable event. Subcontractors often charge a flat call-out fee plus time and materials.
Lng (liquefied Natural Gas) Train
IndustryA single end-to-end processing unit that cools natural gas into liquid form for storage and export. Large LNG facilities run multiple trains, each requiring dedicated construction, maintenance, and shutdown crews. Subcontractors are typically mobilised per train, making scope and schedule highly compartmentalised.
Ngl (natural Gas Liquids) Value Chain
IndustryThe full sequence of extracting, processing, transporting, and selling natural gas liquids such as propane, butane, and ethane. Subcontractors work across multiple stages, including plant turnarounds, pipeline installation, and fractionation facility maintenance. Activity levels and contract demand shift depending on which part of the chain is seeing investment.
Stock Hole
IndustryA pre-drilled or existing borehole kept in reserve for future use on a wellsite. Subcontractors may be mobilised to maintain or re-enter stock holes with little advance notice. Knowing a site has stock holes helps crews plan equipment and standby requirements.
Roadway Decking
IndustryTemporary modular panels laid over pipelines, cables, or trenches to allow vehicle and equipment traffic across a work site. Subcontractors are often responsible for installation, load-rating compliance, and removal. Costs are typically billable as a mobilisation or site-prep line item.
