As-built drawings: Overview, definition, and example
What are as-built drawings?
As-built drawings are detailed and accurate representations of a construction project after it has been completed. These drawings reflect the actual dimensions, locations, and specifications of the building or infrastructure as it was built, including any changes or modifications made during the construction process. As-built drawings are crucial for future maintenance, renovations, or repairs, as they provide an up-to-date, real-world representation of the structure.
For example, if a building’s electrical system is altered during construction, the as-built drawings will show the final, installed configuration, rather than the original planned layout.
Why are as-built drawings important?
As-built drawings are important because they serve as the official record of a construction project, showing exactly how it was built. This makes them essential for future reference, especially when repairs, renovations, or upgrades are needed. They are also necessary for compliance with building codes and regulations and can be required by regulatory authorities after the project is completed.
For businesses involved in construction, architecture, or real estate, having accurate as-built drawings can prevent costly mistakes, help with facility management, and ensure that any future work is done correctly.
Understanding as-built drawings through an example
Imagine a company is building a new office complex. During construction, there are several changes made to the layout of the plumbing and electrical systems to accommodate unforeseen circumstances. After the construction is complete, the project manager ensures that the as-built drawings accurately reflect the final placement of plumbing pipes, electrical wiring, and any other structural adjustments that were made.
In another example, a company renovating an old building might need to consult the as-built drawings to understand the current layout and structural features of the building before starting any new construction work. The drawings provide a clear representation of what is actually in place, avoiding potential problems down the line.
An example of an as-built drawings clause
Here’s how an as-built drawings clause might look in a contract:
“Upon completion of the project, the Contractor shall provide the Client with accurate as-built drawings reflecting all modifications and actual conditions of the construction work.”
Conclusion
As-built drawings are an essential part of construction projects, providing a final, detailed record of how a project was actually built. They are critical for future repairs, renovations, and ongoing maintenance, ensuring that any changes made during construction are properly documented. For businesses in construction or property management, having accurate as-built drawings can help save time, reduce costs, and prevent errors in future work.
