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
Jackup
IndustryA mobile offshore drilling rig with retractable legs that jack down to the seabed, elevating the platform above water. Subcontractors mobilising to a jackup must account for offshore certification, marine logistics, and platform-specific access requirements.
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.
Trenchless Technology
IndustryMethods for installing or repairing underground pipelines and conduits without open-cut excavation. Common techniques include HDD (Horizontal Directional Drilling) and pipe bursting. Subcontractors specialising in these methods often command premium rates due to reduced surface disruption and specialised equipment requirements.
Well Program
IndustryA technical document outlining the planned scope, procedures, and specifications for drilling or completing a well. Subcontractors use it to understand required services, equipment, and sequencing before mobilising. It directly affects how you scope work and price your bid.
Lease Road
IndustryA temporary or permanent access road built to service an oil and gas lease or well site. Subcontractors are often responsible for maintaining or mobilising equipment over these roads. Road conditions directly affect trucking rates, equipment wear, and scheduling.
Frac Flowback
IndustryThe phase after hydraulic fracturing when water, sand, and hydrocarbons flow back to surface from the wellbore. Subcontractors are often mobilised quickly to manage fluid handling, testing, and disposal. Flowback work can be short-duration but requires crews and equipment on standby.
