Author Description

"Utility as-builts are the recorded representation of the built or maintained infrastructure showing the actual location, dimensions, geometry, and other attributes of the completed work. As-builts can serve as a baseline for new design projects by providing information on existing transportation infrastructure and other facilities such as underground and overhead utilities. The objective of this synthesis is to document state department of transportation (DOT) practices related to utility as-built data collection, use, and management. Information for this study was gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected DOTs. Case examples of seven state DOTs provide additional information on utility as-built practices." -- publisher's website
