This report examines the current state of the practice in as-built development and use across the United States. The report documents how state departments of transportation define as-built plans, the information being documented and included on as-built plans, and the methods used to capture and document changes to design plans during construction. The state of the practice was examined by reviewing the literature related to as-built creation and usage, reviewing publicly available state transportation agency policies and procedures related to as-builts, sending an online survey to state transportation agencies, and conducting interviews with state transportation agencies that led to the development of case examples describing the as-built processes at selected agencies. Of the survey respondents, 68% indicated their agency has a documented process for as-built development. States indicated that handwritten notes (86%) were the most commonly used method to capture as-built data, followed by electronic notes (76%) and then photographs (33%). Some states use more than one option to capture as-built data. Advanced technology has changed the accuracy and detail of project plans; however, it seems new technology has not had the same effect on as-built plans. As-builts are typically created by the construction division within STAs. Approximately half of the respondents indicated that as-builts were developed by only agency personnel, and the other half indicated that as-builts were developed using a mix of agency staff, contractors, and/or construction, engineering, and inspection (CEI) consultants. The majority of respondents indicated that as-builts were stored electronically, but 57% indicated that as-builts are also stored on paper hard copy.
