What are the drawings called that are kept up to date as installations are made and given to the building owner upon project completion?

As-built drawings are vital for accurately documenting the final configuration of a project once installation is complete. They represent the actual construction details, including any changes made during the build process, which may differ from the original design intent. These drawings serve several important purposes: they provide a record for the building owner, assist in future renovations or repairs, and are often necessary for compliance with building codes or regulations.

While blueprints and construction plans generally refer to the initial designs and specifications for a project, they do not reflect modifications made during construction. Design schematics are also conceptual representations that guide the project but do not capture the final built conditions. Thus, as-built drawings are specifically designed to update and reflect the completed work, making them the correct answer in this context.
