What Are As-Built Drawings?

As-built drawings are a set of technical drawings that show how a building, structure or system was actually constructed. They are generally produced by a professional surveyor or contractor, and are used to verify that the construction meets the requirements of the original design. As-built drawings are particularly important when it comes to making additions or alterations to existing buildings, as they provide a comprehensive record of the existing construction which can be used to ensure that any modifications are properly integrated into the existing structure.

What Information Do As-Built Drawings Include?

As-built drawings typically include detailed measurements, dimensions and other specifications that are used to verify that the construction meets the requirements of the original design. These drawings may include a variety of different elements, such as the exact locations of walls, doors, windows, pipes, ducts, electrical outlets, and other features of the building. As-built drawings may also include notes and descriptions of any materials used, as well as any special instructions for installation.

Why Are As-Built Drawings Important?

As-built drawings are an important part of the construction process, as they provide a permanent record of how a building or system was actually constructed. This information can be used to ensure that any alterations or additions to the structure are properly integrated into the existing structure. As-built drawings are also useful for maintenance and repair purposes, as they can be used to identify any potential issues or problems before they become major concerns.

Legal Considerations

In some cases, as-built drawings may be required by law. For example, in the United States, the Americans with Disabilities Act requires that all new construction projects meet certain standards of accessibility. As-built drawings are often used to verify that these standards have been met. As-built drawings are also important for insurance purposes, as they provide evidence that the building or system is up to code.

As-built drawings are typically produced by a professional surveyor or contractor who is familiar with the construction process. This individual will typically use a combination of drawings, photographs, and measurements to create an accurate record of the existing structure. This information can then be used to create a set of technical drawings that accurately represent the existing construction.
