As built documentation
As built documentation refers to the final documentation of a construction or industrial project, updated to reflect the actual implementation. It includes all changes and deviations from the original design that occurred during the project.
Accurate as built documentation supports future maintenance, repair and extension work by providing a clear record of the current state of the structure or system. Third-party as built documentation is often used in large-scale projects to ensure reliability and credibility.
