Compression Station

A casing string run inside an existing wellbore to line the productive zone without extending to surface. Subcontractors are often mobilised for liner running, cementing, and pressure testing during completion operations. Work is typically time-sensitive and tied to rig-day rates.

A watertight steel or concrete structure used to support foundations in offshore or waterlogged environments. Subcontractors may be scoped to install, inspect, or perform maintenance work on caissons. Access and confined space protocols often apply.

A method of installing or repairing underground pipelines and conduits without open excavation. Techniques include horizontal directional drilling (HDD) and pipe bursting. Subcontractors working trenchless scopes need specialised equipment and certified operators.

A category of ongoing field service work covering routine inspections, preventive maintenance, and corrective repairs on infrastructure or equipment, often awarded to subcontractors through standing agreements or blanket contracts. For field service companies, IMR scopes provide a reliable stream of recurring work but typically require crews to mobilise quickly and hold multiple trade certifications to meet operator requirements.

The detailed engineering phase before a project is sanctioned for full construction. For subcontractors, FEED signals that scopes, specs, and vendor lists are being finalised. Winning work during FEED often positions your company for contracts in the execution phase.

Milled or crushed material salvaged from existing asphalt surfaces during road removal or rehabilitation work. Subcontractors reuse RAP as base material or blend it into new asphalt mixes, reducing material costs. Proper handling and testing requirements may apply depending on project specs.
