Refers to the three core building systems subcontractors install and maintain on construction and industrial facility projects. MEP scopes are often divided among specialised trades, each holding separate contracts or working under a prime contractor. Understanding MEP divisions helps subcontractors define their scope, avoid overlap disputes, and price work accurately.
MEP (Mechanical, Electrical, and Plumbing)
Related Terms
Processing Train
IndustryA series of vessels and equipment that separates wellhead fluids into oil, gas, and water. Subcontractors are often scoped to one train at a time, so know which train your work order covers. Shutdowns or upsets on your train can directly affect your crew's schedule and completion milestones.
Pad Drilling
IndustryA method where multiple wells are drilled from a single surface location, or pad. For subcontractors, this means sustained, back-to-back work cycles with minimal rig-up and tear-down time. Efficient mobilisation and crew scheduling are critical to maintaining productivity across the pad.
Brent Crude
IndustryA globally traded North Sea oil benchmark used to set crude pricing contracts. When Brent prices rise or fall sharply, operators often adjust project budgets, affecting subcontractor work volumes and day rates. Monitoring Brent helps field service companies anticipate slowdowns or ramp-ups in awarded work.
Gathering System
IndustryA network of pipelines, compressors, and facilities that collect hydrocarbons from wellheads and move them to processing points. Subcontractors frequently support construction, inspection, and maintenance work across these systems. Scopes can span remote multi-well pads, requiring strong logistics and crew coordination.
Design-Bid-Build
IndustryA project delivery method where design is completed before subcontractors are invited to bid. Scope is fully defined upfront, reducing ambiguity in your quote. Common in construction; less flexible once awarded, so price your bid carefully.
Sand Management
IndustryThe process of controlling, monitoring, and removing sand produced alongside oil and gas to protect wellbore equipment and surface facilities. Subcontractors may be hired to install sand screens, separators, or erosion monitoring systems. Poor sand management accelerates equipment wear and increases maintenance callouts.
