What does the term “as built” documentation refer to?

The term “as built” documentation specifically refers to drawings that accurately reflect the final construction of a project as it was completed. These drawings incorporate all changes made during the construction process, including modifications to dimensions, materials, and systems that may have occurred from the original design to the finished structure. This documentation serves as a crucial reference for future maintenance, renovations, and understanding the actual configuration of the built environment, making it an essential component of project documentation in architecture and construction.

The other choices pertain to different types of documentation: proposed alterations would be represented in schematic or design development drawings, initial plans would encompass blueprints or design drawings prior to construction, and maintenance reports are typically focused on the upkeep of a building rather than its physical representation. "As built" documentation stands out because it specifically records the completed state of a project following all modifications made during construction.
