Note: While the terms “as-built” and “record drawings” are often used interchangeably, we recommend only using the former. When it comes to renovation, as-builts are crucial to understanding a building as it currently exists so that there can later be efficient and safe changes. This is especially useful for commercial construction.Īs-fitted drawings are used for new construction, building maintenance, and renovation projects. As-built drawings record these deviations and maintain an accurate representation of the structure as it currently exists. Over the course of a construction project, features of the structure may change due to obstacles with the site or materials, or due to governmental regulations. Generally, the contractor will mark up changes to the original design on site with red ink. While an architect might be involved, this is not common, since architects typically do not oversee the daily building process.Ĭontractors are on site during construction, so they are able to make timely and more frequent updates to the building plans. They are usually prepared by the contractor either during the construction process or after the construction is complete. This is in contrast to design drawings, which show the proposed or intended layout. They show the existing dimensions of a building, area or space. Introduction: What are As-Built Drawings and Who Prepares Them?Īs-built drawings are part of the construction documentation process and are also called as-made drawings, as-fitted drawings, as-constructed drawings, and record drawings.
