Which statement best describes the difference between shop drawings and as-built drawings?

• A. Shop drawings are prepared by the contractor for fabrication/installation planning; as-built drawings record the actual constructed configuration
• B. Shop drawings record actual constructed configuration; as-built planning
• C. Shop drawings are prepared by the owner; as-built by contractor
• D. Shop drawings are optional documents with no impact on construction

Answer: (A)

The main idea is understanding what each type of drawing is used for and who creates it. Shop drawings are detailed plans prepared by the contractor (or subcontractors) showing exactly how components will be fabricated and installed, based on the design drawings. They specify dimensions, materials, tolerances, and fit-ups, and they’re typically submitted for review and approval to ensure everything will work together and meet design intent. As-built drawings, on the other hand, are the record of what was actually constructed. They document the final configuration in the field, including any changes, deviations, or unexpected conditions that occurred during construction. So the best statement reflects that distinction: shop drawings are contractor-generated for fabrication/installation planning, while as-built drawings record the actual constructed configuration. The other options mix up who prepares the drawings or what they document, or imply shop drawings are optional, which isn’t accurate.
