What is the role of shop drawings in millwork and casework installation?

• A. They are optional and rarely used.
• B. They replace architectural drawings.
• C. They provide precise fabrication dimensions, profiles, tolerances, hardware locations, and assembly details.
• D. They only show color swatches.

Answer: (C)

Shop drawings translate design intent into exact fabrication and installation instructions. They provide precise fabrication dimensions, profiles, tolerances, hardware locations, and assembly details, so the millwork is cut, shaped, joined, and finished to fit the actual space. These drawings guide the fabricator on every detail—moldings and profiles, where hinges, pulls, and fasteners go, and how pieces come together, including required clearances and sequencing.

They also capture field conditions and coordination needs, showing how the millwork interfaces with walls, openings, doors, and other built-ins, as well as where penetrations or clashes with electrical, plumbing, or HVAC occur. Because they are based on the architectural and structural drawings, they supplement those documents rather than replace them, and they are not about color swatches but about exact construction and installation instructions.
