Author Description

As-builts, inclusive of utility as-builts—which are the recorded representation of the built or maintained infrastructure and show the actual location, dimensions, geometry, and other attributes of the work as completed—can provide a baseline for new design projects by providing information on current transportation infrastructure and other facilities such as underground and overhead utilities. The TRB National Cooperative Highway Research Program's NCHRP Synthesis 600: Practices for the Collection, Use, and Management of Utility As-Built Information aims to document current state departments of transportation practices related to utility as-built data collection, use, and management.
