34 Development and Use of As-Built Plans by State Departments of Transportation As-Built Information Received from Third-Party Agencies Third-party agencies can share record drawings in one of two ways. Record drawings can be e-mailed directly to Arizona DOT as PDFs, or as a link to the record drawings from the company site or file-sharing site.

Case Examples 35 As-Built Information on Warranties, Agreements, and Deployed Technology Colorado DOT does not perform projects with warranties. Its contracts for projects with agreements or deployed technology are the same as all contracts; therefore, as-built development does not differ for these projects.

38 Development and Use of As-Built Plans by State Departments of Transportation Incorporation of As-Built Data into Asset Management Currently, as-built data are not being incorporated into asset management and little discussion on asset management was present in interviews. However, as research on as-built procedures continues at KYTC, this is an area for consideration and enhancement.

Case Examples 39 Currently, Minnesota DOT is tracking let construction projects and as-built usage, communicating District 2018 projects and the status of the data, conducting monthly statewide as-built working group meetings, and compiling special provisions/website changes. Next steps include a case example on utilizing as-built data, adding asset classes to 2011.601, continuing to build contractors' expertise, and improving the business process.

42 Development and Use of As-Built Plans by State Departments of Transportation As-Built Information on Warranties, Agreements, and Deployed Technology Projects with warranties, agreements, or deployed technologies do not require additional or different as-built information than any other projects at Virginia DOT. However, as stated previously, contractors are most likely responsible for ITS project as-builts.

Case Examples 43 Varying As-Built Procedures According to Project Delivery Method Different projects at Wisconsin DOT may have different approaches to as-built development, such as using 3-D models for the megaproject in Milwaukee. However, Wisconsin DOT is only allowed to perform design–bid–build projects; therefore, there is no variation in project delivery method.
