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
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.
Tubulars
IndustrySteel pipes used in drilling and well construction, including casing, tubing, and drill pipe. Subcontractors handling tubulars must follow strict inspection and handling procedures. Damage during your scope can result in costly liability claims.
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.
Hot Shot
IndustryExpedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.
Gyroscopic Guidance
IndustryA downhole navigation system that uses gyroscopes to track drill bit position and direction without magnetic interference. Subcontractors use it in areas where magnetic tools fail, such as near casing or in high-latitude regions. Accurate wellbore placement reduces costly corrections and keeps projects on schedule.
Saas (software As a Service)
IndustryCloud-based software you access via subscription instead of buying and installing it outright. For subcontractors, this covers tools like invoicing, scheduling, and compliance tracking platforms. You pay a recurring fee and can access the software from any jobsite device.
