Which drawing type is prepared to show fabrication and installation details by manufacturers or contractors?

• A. Coordination drawing shows integration.
• B. As-built drawing shows current field conditions.
• C. Shop drawings show fabrication and installation details from contractors.
• D. Schematic drawing shows initial concept.

Answer: (C)

The key idea is that shop drawings are the fabrication and installation road map created by contractors or fabricators. They take the design intent and break it down into detailed, buildable information the trades need to fabricate components and install them on site. This includes exact dimensions, materials, welds or connections, fasteners, finishes, tolerances, and installation sequences, all tailored to how the item will actually be manufactured and assembled. They’re often submitted for review to ensure the proposed fabrication and installation align with the design drawings and project requirements before work proceeds. Other drawing types serve different purposes: coordination drawings focus on showing how systems from various trades fit together and interface, not the exact fabrication details of a single component; as-built drawings record what was actually constructed in the field; schematic drawings illustrate early design concepts and overall arrangement, not the precise fabrication or installation details used in production.
