What is an as-built drawing?

An as-built drawing is a comprehensive document that accurately represents a construction project's final state after completion. It includes all modifications and adjustments made during the construction process, reflecting the actual dimensions, locations, and details of the completed work. These drawings are valuable for project documentation as they provide a clear visual record of how the project was actually built, including any changes from the original design during the construction phase.

This detailed record is essential for future maintenance, repairs, and renovations, as it allows engineers, architects, and contractors to understand the real conditions of the structure as opposed to the initial design intent. The reliance on as-built drawings ensures that any future work can be carried out with a clear and accurate understanding of what exists at the site.
