What does "as-built documentation" refer to in the context of construction?

"As-built documentation" refers specifically to the records that reflect the actual construction changes made during a project. This documentation is critical because it captures any variations from the original design, whether those changes were due to alterations on-site, modifications for compliance to regulations, or adjustments for unforeseen conditions.

Having accurate as-built records ensures that future maintenance, renovations, or improvements can be effectively planned based on the real conditions and configurations of the built structure. These documents serve as an essential reference point for current and future stakeholders involved with the building.

The other choices, such as blueprints before construction starts or plans for future modifications, do not capture the essence of as-built documentation, which is focused solely on what was actually built, rather than what was initially planned or speculated for the future.
