As-built drawings are an essential part of every construction project. The main purpose an as-built drawing serves is to replicate how the contractor built the project and identify what changes were made throughout the course of constructing the project. The final sets of as-built drawings hold important information; such as shop drawing changes, design changes, field changes, approved and disapproved changes during construction, and any minor or major modification to the final resulting project.

As you can imagine, any construction project goes through many changes and modifications before reaching completion, no matter how minor these modifications are, recording as-built drawings visualizes the changes being made and how it will affect the remainder of the project.

What is an “as-built” drawing?

By definition, an as-built drawing is a revised set of drawings submitted by a contractor upon completion of a construction project. As-built drawings show the dimensions, geometry, and location of all components of the project. These 2D floor plans commonly include details such as walls, doors, windows, and plumbing fixtures. One of the main purposes of an as-built drawing is to be able to document any changes made during construction of the project that strays away from the original design.

These drawings are typically composed by architects and designers, they are the ones to create the drawings because they have the most training and talent in doing so; however, they are not always on site to see the work being done first hand, meaning they can sometimes be liable for inaccuracies in the completion of the project.
