Record drawings are usually developed from shop drawings by whom?

• A. Contractor or Equipment Supplier
• B. Architect
• C. Owner
• D. Consulting Engineer

Answer: (A)

Record drawings capture exactly what was actually built, including any field changes or deviations from the original design. The contractor or equipment supplier is best positioned to prepare them because they performed the installation and have direct, detailed knowledge of the on-site conditions, device locations, wiring runs, and terminations. They translate the shop drawings into an accurate reflection of the installed system, which is essential for maintenance and future alterations. Architects and consulting engineers create the design and the initial shop drawings, but the as-built or record drawings come from those who completed the installation. The owner may request them, but the responsibility typically rests with the contractor or equipment supplier who can verify and update the drawings to match reality.
