When a subcontractor provides their own tools, equipment, or materials rather than relying on the prime contractor or client. This shifts procurement responsibility — and often cost risk — directly to your company. Pricing your bids correctly to recover these costs is critical.

Geosteering
IndustryThe real-time technique of guiding a drill bit through a target formation using geological data. Subcontractors supporting drilling operations may be called in on short notice as geosteering decisions change well paths. Expect scope adjustments and rapid crew or equipment mobilisation when geosteering is active.
Easement
IndustryA legal right allowing access to land owned by someone else for a specific purpose, such as running pipelines or power lines. Subcontractors must confirm easement boundaries before mobilising equipment or breaking ground. Working outside easement limits can trigger legal liability and project shutdowns.
Distribution Infrastructure
IndustryThe pipelines, power lines, roads, and utility networks that move resources from production sites to end users. Subcontractors are frequently hired to build, inspect, or maintain these systems. Work can span remote corridors, requiring careful logistical and safety planning.
Corrective Maintenance
IndustryRepair work performed after equipment has already failed or broken down. For subcontractors, it often means urgent mobilisation and unplanned labour costs. Scope can expand quickly, so clear change-order procedures are essential.
Completion Crews
IndustrySpecialised teams mobilised after drilling to prepare a well for production. For subcontractors, they represent a distinct scope of work with separate contracts, timelines, and crew requirements. Demand is tied directly to operator completion schedules, affecting short-notice mobilisation and billing cycles.
Hydrotesting
IndustryA pressure test using water to verify the integrity of pipelines, vessels, or equipment before commissioning. Subcontractors are often scoped separately for hydrotest labour, equipment, and water disposal. Confirm whether these costs are included in your contract or billed as extras.
