What Is an As-Built in Construction?

What the term means

An as-built in construction is a document, usually a drawing set, that records a structure exactly as it was actually built, capturing any changes made during construction that were never reflected back into the original design drawings.

These changes happen for many reasons, field conditions, contractor substitutions, or client-requested adjustments made during the build, and an as-built exists specifically to capture the final result accurately.

Why as-builts matter

As-built documents are essential for future renovation, addition, or maintenance work, since starting from an inaccurate original drawing set can lead to design errors on any future project involving the structure.

As-builts are also commonly required for permitting closeout, insurance documentation, and property transactions, where an accurate record of the built structure is needed rather than the original design intent.

• Records a structure exactly as it was actually built
