A build method where structures are assembled from prefabricated units manufactured offsite, then transported and installed on location. Subcontractors are often scoped for site prep, mechanical tie-ins, or installation crews rather than full builds. Work tends to come in concentrated, short-duration packages tied to delivery schedules.

Related Terms
Oil Rigs
IndustryStructures used to drill for oil and gas, either onshore or offshore. For subcontractors, they are primary worksites where specialised services like maintenance, inspection, and equipment supply are contracted. Mobilisation requirements, safety certifications, and site access protocols vary significantly between rig types.
Master Service Agreement (MSA)
IndustryA contract between an operator and a service company that establishes the general terms and conditions for all future work. Individual jobs are then executed under work orders or AFEs referencing the MSA.
Mission Critical
IndustryDescribes any task, system, or equipment whose failure would halt operations or create serious safety risks. For subcontractors, mission critical work often carries stricter response times, higher liability, and tighter documentation requirements.
Marine Construction
IndustryOffshore and nearshore infrastructure work including platform installation, subsea pipelines, and dock or jetty builds. Subcontractors often face strict vessel access requirements and marine safety certifications. Mobilisation costs and weather delays are major contract risk factors.
Integration Gap
IndustryThe disconnect that occurs when a subcontractor's systems cannot communicate directly with a prime contractor's or operator's software platforms. This forces crews to manually re-enter data such as timesheets, work orders, or inspection records. The result is delays, billing errors, and compliance risks in the field.
Distribution System
IndustryA network of pipelines, valves, and infrastructure that moves oil, gas, or utilities from a main supply point to end users. Subcontractors are often hired to install, inspect, or maintain these systems. Work scope can include trenching, pipe fitting, and pressure testing across large service areas.
