The planning phase before field work begins, covering scope review, site assessments, and schedule alignment with the GC. Subcontractors are often engaged during this phase to provide pricing, labour forecasts, and constructability input. Early involvement can improve mobilisation timelines and reduce costly scope changes later.
Preconstruction
Related Terms
Critical Path
IndustryThe sequence of tasks that directly controls a project's completion date. Delays to any critical path activity push the whole project's finish date back. Subcontractors on critical path work face tighter scrutiny and stronger pressure to meet scheduled milestones.
Preventive Maintenance
IndustryScheduled servicing of equipment before failures occur, reducing costly downtime on job sites. Subcontractors are often contracted specifically to perform PM work on client assets. Documented PM records also support compliance audits and contract renewals.
Guidance Engineer
IndustryA specialist who oversees directional drilling operations, ensuring wellbores are steered accurately to target zones. Subcontractors often supply these roles to operators on a contract basis. They work closely with MWD (Measurement While Drilling) technicians on site.
Field Gathering Lines
IndustryPipelines that collect oil, gas, or water from individual wellheads and route it to a central processing facility. Subcontractors frequently work on installation, inspection, and maintenance of these lines. Knowing the layout is essential for safe excavation and tie-in work.
Sanctioned Field
IndustryA field development that has received formal investment approval from the operator or project owner. For subcontractors, sanction signals that contracts, mobilisation, and work orders are imminent. It marks the transition from planning to active field execution.
SMR (Small Modular Reactor)
IndustryA compact, factory-built nuclear power unit used to generate on-site electricity for remote industrial facilities and resource projects. For subcontractors, SMR sites represent emerging work in civil, electrical, and mechanical trades. Expect strict federal nuclear safety compliance requirements affecting worker certifications and site access.
