As-Built Drawing

Category: infrastructure

Final blueprints that reflect the actual, physical construction of the space after all field adjustments have been made.

Design drawings are theoretical; as-builts are reality. When a contractor encounters a hidden pipe in the wall and moves a doorway six inches, the as-built drawing must be updated to record this shift. It is the vital "truth" document for all future renovation or repair work.

Common Examples

• Always request the as-built drawing set before starting the remodel, as the original plans rarely match the reality inside the walls.
• The electrical engineer used the as-built drawing to trace the actual path of the wiring before attempting to install the new smart-home hub.
