48 A P P E N D I X A Survey Questionnaire NCHRP TOPIC 50-12 SURVEY QUESTIONNAIRE NOVEMBER 2018 Synthesis [Topic] 50-12 seeks to document how as-built plans are developed, used, and updated for State Transportation Agencies (STAs). The synthesis will attempt to document how STAs define as-built plans. It will also attempt to document what information is being included on STA as-built plans and methods used to capture such information. Additional information gathered will include platforms and entities used to develop as-built plans, approval and preservation of as-builts, uses of approved as-built plans, retrieval of as-built information for legal purposes, transfer of as-built information from third-party agencies, and differences in as-built plans for various project types such as Design–Bid–Build, Design–Build, Construction Manager/General Contractor, and Public-Private Partnerships. General Information 1. Does your agency use a documented procedure for developing as-built plans? Yes No 2. Please attach any as-built development documentation below. Click here to enter text. 3.

Sixty-eight percent of the states who responded to a survey indicated their agency has a documented process for as-built development. They said handwritten notes were the most commonly used method to capture as-built data (86%), followed by electronic notes (76%), and then photographs (33%). Some states use more than one option to capture as-built data.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 548: Development and Use of As-Built Plans by State Departments of Transportation examines the current state of the practice in as-built development and use across the United States.

Over the years, as-built plans have been the method used by the construction industry to capture and record construction changes and additions that are not represented in the original plan drawings. The accuracy and completeness of these plans are essential for operations, maintenance, and rehabilitation of current transportation infrastructure.
