What Are As Built Drawings
Definition and purpose
As built drawings are a revised version of the original construction documents that show a building exactly as it was actually constructed, including any field changes, substitutions, or adjustments made during the build that differ from the original design set.
They are typically produced at project closeout by the contractor, architect, or a specialized drafting service, and are required by many owners, lenders, and facility managers as part of the final project handover.
Why they matter after construction
As built drawings become the reference document for future renovations, maintenance, and facility management, since they show the true location of walls, MEP systems, and structural elements rather than the originally designed layout, which often changes during construction.
- Document actual field conditions, not just the original design
- Typically required for project closeout and handover
- Used as the reference for future renovations and maintenance
- Cover architectural, structural, and MEP systems as built
