The shop drawings for the mechanical, electrical, and plumbing (MEP) systems of new building construction are unique in that they provide the greatest details of these systems when compared to other documentation sets.
Often, the architectural and/or engineering firm tasked with designing a commercial or industrial facility will outsource the MEP shop drawings to another party.
In this way, complete focus and a speedy turn-around can be given for an accurate drafting of assemblies and components which require fabrication versus purchase only.
HVAC or mechanical components which may require prefabrication include ductwork, air-handling units, and custom piping connections between equipment and building services.
But, also elevators and cabinet systems are mechanical components which require fabrication or shop drawings.
The final dimensional accuracy of fabricated building components are taken from shop drawings, rather than the design detail and layout drawings prepared by an architect or engineer.
