Design-Build

A section of pipeline, conduit, or cable routed beneath or across a river, creek, or other body of water. Crossings typically use methods like horizontal directional drilling (HDD) or open-cut trenching. Subcontractors must meet strict environmental permits and inspection requirements before and after installation.

A document created in the field that records work performed, equipment used, materials consumed, and time spent. Field tickets are the basis for invoicing and must typically be approved by the customer before payment.

A scope-of-work term covering all field service activities from the producing wellhead to the point of water disposal or treatment. For subcontractors, it defines mobilisation boundaries and billable work limits on produced-water handling projects. Knowing this scope prevents disputes over who owns each task segment.

A sealed system that transfers heat between two fluid circuits without them making direct contact. Subcontractors service these units for cleaning, inspection, and pressure testing. They are common in oilfield facilities, compressor stations, and industrial construction sites.

The equipment and techniques used to lift, secure, and move heavy loads on a job site. Subcontractors must ensure all rigging gear is certified and operators are ticketed. Improper rigging is a leading cause of serious incidents and contract liability.

A company hired to deliver an entire scope of work, rather than splitting it among multiple subcontractors. For field service subs, this means one firm holds the prime contract and manages all trades underneath. Winning a single-source role improves cash flow and reduces competition, but increases liability exposure.
