What is the purpose of “as constructed plans” required by a chief building official?

The purpose of "as constructed plans," also known as "as-built drawings," is to provide accurate representations of completed work. These plans are created after the construction process has been completed and reflect any changes made during the course of the project. They document the final specifications and layouts of the building, including the locations of structures, materials used, and any deviations from the original design plans.

This documentation is crucial for several reasons: it serves as a reliable record for future renovations or repairs, assists in maintaining compliance with building codes and regulations, and is beneficial for property management and ownership transitions. Accurate as constructed plans are essential for the chief building official to ensure that the building complies with the approved permits and to inspect the work against the original and revised plans.
