What As-Built Drawings Cover and When They Are Needed
What as-built drawings document
As-built drawings document the exact condition of a building or space after construction, capturing dimensions, layouts, and structural or mechanical details that may have changed from the original design during the building process.
They can cover a single room, a full building, or specific systems like electrical or plumbing layouts, depending on what the project needs documented.
How they are produced
As-built drawings are typically produced through a site visit involving physical measurements, laser scanning, or photogrammetry, followed by drafting the collected data into accurate CAD drawings.
For older buildings with no reliable existing plans, as-built documentation may be the only accurate record of the structure available before renovation work begins.
