What does "as-built" documentation signify in MEP projects?

"As-built" documentation is crucial in MEP (Mechanical, Electrical, and Plumbing) projects as it serves to represent the final installation details that reflect any changes made during the construction process. This documentation provides a comprehensive account of what was actually built, as opposed to what was originally designed.

It includes details such as modifications that were necessary due to site conditions, changes made to the design, and any other variations that occurred throughout the project. This thorough reflection ensures that future renovations, maintenance, or inspections have accurate reference material, making it invaluable for the lifecycle of the building.

In contrast to other phases, such as proposals for future construction or preliminary drafts of a design, "as-built" documents capture the real-world outcome of the project post-completion. They are not regulatory documents, which differentiates them from guidelines that outline installation rules and regulations. This focus on finality and accuracy is why "as-built" documentation is recognized as a significant component in MEP projects.
