What is an as-built plan?

An as-built plan is defined as a detailed representation of a project that reflects all changes made during the construction process, including modifications to the original design. This type of plan incorporates all corrections, alterations, and actual dimensions of the completed project. It serves as an important record that helps ensure accurate future maintenance and any subsequent improvements.

By capturing the work as it was actually built, rather than how it was initially designed, an as-built plan provides a valuable reference for facility management and can also be useful for identifying existing conditions related to construction or further renovations. Its primary purpose is to document the actual built environment, maintaining accuracy for future reference.

The other options do not accurately capture the essence of an as-built plan. A preliminary draft does not reflect the completed work, while a plan that indicates solely underground utilities or one that shows only the finished landscape fails to encompass the complete scope of changes made during construction. Thus, the correct definition centers on its role as a corrected or redrawn plan that represents the final state of the project.
