The short answer

Designs and coordinates mechanical, electrical and plumbing systems so services fit the architecture and perform efficiently.

MEP consultants size electrical loads, design lighting and power layouts, plan water supply, drainage and fire systems, and specify air-conditioning and ventilation. Their drawings must be coordinated with the structure before casting.

On houses, a scaled-down MEP scope is usually enough; on commercial, hospitality and healthcare projects it is essential. Late MEP coordination is the most common cause of cutting chases into finished walls.
