ABSTRACT
Without the use of Building Information Modeling (BIM), MEP coordination begins after the design and preliminary routing of all building systems (mechanical, plumbing, electrical, etc.) is complete. The design is considered complete when engineers have sized all components (e.g., HVAC duct, pipe, conduits), completed the engineering calculations, and produced the diagrammatic drawings. Representatives from each of the specialty contractors (primarily HVAC wet and dry, plumbing, electrical, and fire protection) meet to discuss their particular designs and drawings, which indicate the proposed routing for each system to follow to service each required location. Most specialty contractors refer to these contract drawings as schematic design drawings. The engineers’ stamp that the engineer provides only insures that the design of the systems will work functionally. It does not ensure that the system will actually fit within building.
