2highway-design work and demonstrating the suitability of the overall solution for future DOT renewal projects. The SHRP 2 R01A pilot project at Route 29 and Gallows Road established a number of administrative and technological practices required to acquire, preserve, and maintain the utility record for all future projects.

3Content Management System The content management system allows the collection of utility data in many different formats and serves multiple purposes. The system • Provides a staging platform for collection of utility data and any associated records for processing into the 3-D utility model; • Allows the classification of underground utility source data to ASCE 38 quality levels; and • Will allow for direct viewing of the base files in 2-D space.

4Instituting a change control process over project sites is a key R01A project recommendation for avoiding re-inventory of entire underground utility systems. In particular, a permitting process will serve as a primary way to avoid re-inventory when underground utility data are changed and will ensure that the underground utility system of record can be relied on for use in future highway renewal projects.
