Why is it essential to maintain accurate as-built documentation?

Maintaining accurate as-built documentation is essential because it serves as a comprehensive record of all historical changes made to a project during construction. This documentation reflects the final state of the project, capturing variations from the original design, and is critical for future reference. It aids in understanding the actual configuration and conditions of the built environment, which is invaluable during maintenance, renovations, or any future projects involving the structure. By having a complete and accurate account of these changes, stakeholders can make informed decisions, address any issues efficiently, and ensure that any subsequent work is appropriate and informed by the existing conditions of the project.
