As Built drawings are some of the most important components of any construction project. These are revised drawings of a site that will be detailed for displaying the refinements or variations made on an original design. Commonly the As Built drawings are developed by the contractor. All throughout the total duration of the building project, a contractor needs to determine how the existing structure appears to be as it is an essential aspect of applying adaptations to that particular development project. Any changes that are made on the actual structure such as a piping system will be documented fully and comprehensively on the As Built drawings. Notes, drawing and modifications will be featured in the As Built drawings that will in turn help to prevent unnecessary interruptions with the main construction process.
