What are as-fitted plans used for in building services?

As-fitted plans are crucial documents in the construction and building services sectors. They provide an accurate representation of the systems that have been installed in a building after all construction work is completed. This includes the actual dimensions, configurations, and locations of services such as HVAC, plumbing, electrical systems, and any other installed building services.

The primary purpose of as-fitted plans is to document what has been put in place, which can differ from the original designs due to changes made during construction or site-specific adjustments. This documentation is essential for various stakeholders involved in the project, including facility management, maintenance teams, and future renovations or modifications. Having precise records of the installed systems helps ensure that any future work carried out on the systems can be done with a clear understanding of the existing layout and components.

Other options like designing new systems, testing system safety, or training maintenance staff are related but do not capture the specific role of as-fitted plans, which is to reflect the reality of what was installed.
