What is the purpose of an as-built drawing?

An as-built drawing serves the important purpose of documenting the actual construction of a structure as it was completed. These drawings reflect any changes that were made during the construction process compared to the original plans. This accurate representation is crucial for future renovations, maintenance, and any potential repairs, as it provides a reliable reference for what exists on-site, including dimensions, materials used, and changes made during construction.

By ensuring that the drawings align with the completed work, stakeholders can understand the final state of the project, which is essential for effective management and long-term planning. This is particularly valuable when dealing with alterations or additions to the structure, as it highlights discrepancies that might otherwise lead to complications.
