as-built
Reflecting final construction
As-built describes documentation—typically drawings, plans, or records—that shows how something was actually constructed, as opposed to the original design specifications.
Construction projects often deviate from initial plans due to site conditions, cost changes, or practical constraints.
As-built drawings capture the final reality: The contractor submitted as-built plans showing where the pipes were actually installed.
Essential for maintenance, renovations, and future work on the structure.
