What You Need to Know about As-Constructed Drawing

At Marblaze, as-constructed or as-built drawings are one of the services that we provide. In general, as-constructed draws make up an important part of every building project. But what makes them so vital to the process?

What are as-constructed drawings?

Simply put, as-constructed drawings are revised drawings created once the building of a construction project is completed. They contain changes made to and deviations from the original drawing, also called building plan. Contractors submit them to the Council along with the original plan for final approval of the construction project.

Who is responsible?

Although it is the architects and designers that create the original plans for a construction project, it is usually the contractors that are responsible for the creation of as-constructed drawings. Contractors are the people who are in control of as-constructed drawings. When they make decisions that deviate from the original plan, they annotate the original drawing and engage the services of a drafting company like, Marblaze, to recreate the plan and reflect the changes. The new drawing is commonly referred to as-constructed or as-built drawings.

Why are they important?

What makes as-constructed drawings so important is how greatly they are used as point of reference. A good example is how they can be used as a base to help visualize the revisions made to an original plan. Additionally, if issues in the construction were to occur, or if a specific item or object needs to be located, the as-constructed drawings make it easier for contractors to identify where they are, because of the specifications that they contain. In other words, as-constructed drawings are important tools for onboarding, permit approval and future renovation.

Conclusion

Without As-constructed drawings, the documentation of construction projects would be very difficult. They are drawings that contain changes and revisions made to a building plan during construction. As-constructed drawings become a good source of reference as a base for planning, a tool for locating specifications, and more.
