MEP engineering
A company which designs mechanical, electrical, and plumbing systems in a structure.
Engineering firms which combine the mechanical, electrical, and plumbing engineering functions.
MEP names the combination of mechanical, electrical, and plumbing engineering. The firm brings those design functions together rather than being identified by just one of the three disciplines.
Mechanical engineering addresses mechanical and climate-control systems, while electrical engineering and plumbing engineering address their respective systems. MEP is the combined engineering function, distinct from installing the equipment.
