MEP (Mechanical, Electrical, Plumbing)

In Plain English

The building systems that handle heating, cooling, ventilation, electrical power, and plumbing.

Definition

MEP refers collectively to the mechanical (HVAC and plumbing), electrical, and plumbing building systems that serve a building's environmental and operational needs. MEP engineers design these systems, MEP subcontractors install them, and MEP coordination is critical during BIM modeling because these systems often conflict in ceiling and wall cavities. MEP represents a significant portion of construction cost—often 30–40% or more on complex projects such as hospitals or laboratories.

Example

The BIM coordinator runs weekly MEP coordination meetings to resolve conflicts between ductwork, conduit, and piping in the hospital's interstitial space.
