The exact date when each of these terms entered common use is difficult to determine, but we are comfortable saying that “measured drawing” and “record drawing” have been used for more than 100 years. They are often compiled as a set of on-site changes made for the owner per the owner-architect contract. Record Drawings: Record drawings are prepared by the architect and reflect on-site changes the contractor noted in the as-built drawings. They are created from on-site measurements. Measured Drawings: Measured drawings are prepared in the process of measuring a building for future renovation or as historic documentation. They show, in red ink, on-site changes to the original construction documents The meanings of as-built drawings, record drawings and measured drawings can be confusing and misapplied, and the AIA receives many queries about the definitions and use of these terms in contemporary practice.Īs-Built Drawings: As-built drawings are prepared by the contractor.
