Shop Drawings

Shop drawings are detailed drawings prepared by a contractor, subcontractor, or supplier that show exactly how a specific component will be fabricated and installed — far more precise than the design drawings they are based on.

They translate the architect's and engineer's intent into buildable detail for items like structural steel, millwork, curtain wall, or mechanical equipment. They are submitted for the design team's review and approval before fabrication begins.

Shop drawings are one of the most common types of submittal, and reviewing them against the drawings and specifications is part of keeping procurement and scope aligned — the kind of preconstruction coordination Quotr helps teams manage.

For fabricators and subcontractors, approved shop drawings are the go-ahead to build. For general contractors and designers, they are a checkpoint to catch errors before material is cut.
