What are record drawings and operation manuals used for after occupancy?

• A. Provide a preliminary design concept sketch.
• B. They document as-built conditions and provide system operation and maintenance information for building owners.
• C. Set the project budget for post-occupancy.
• D. Schedule future renovations.

Answer: (B)

Record drawings capture the as-built conditions, showing exactly what was installed, where systems and components are located, and any changes made from the original design. Operation manuals provide the information needed to operate and maintain those systems, including equipment specifications, start-up and shut-down procedures, maintenance schedules, warranty terms, and vendor contacts. After occupancy, these documents become the owner’s reference for ongoing maintenance and for planning future renovations or repairs, ensuring work reflects what was actually built. They’re not used to generate preliminary design concepts, set a post-occupancy budget, or schedule renovations on their own.
