MEP coordination

MEP coordination is the collaborative BIM process of integrating and checking the building-services models — mechanical (HVAC), electrical and plumbing, often with fire protection and low-voltage — against architecture and structure, so the systems fit the available space and can be installed without interference. It is coordination focused on the parts of a building that are hardest to fit together.

It is one of the highest-value uses of model coordination for a simple reason: services are dense and all compete for the same limited space — ceilings, risers, shafts, plant rooms, corridors. Getting them to fit on a model first avoids clashes, rework and on-site improvisation in exactly the congested zones where clearances and routing priorities are tight. In practice MEP is usually where coordination earns its keep.

The workflow combines the discipline models into a federated model, runs clash detection to find conflicts between services and against structure, then assigns and tracks each issue through BCF so it is resolved, re-checked and closed with an audit trail — work typically run by the BIM Coordinator. Good coordination also means coordinated spatial zoning and routing priorities before installation. The governing framework is ISO 19650 plus BCF (and UNI 11337 in Italy). In Italian it is the coordinamento impiantistico (or coordinamento MEP).
