Synthesis of Information Related to Highway Practices. Topic 53-04. Practices for the Collection, Use, and Management of Utility As-Built Information

In a recent Federal Highway Administration review of state department of transportation (DOT) utility programs, federal regulations cited the need for states to improve in their inspection and collection of utility as-built information as part of relocation operations. It has further been noted that utility as-built information as collected through permitted accommodations varies substantially by DOT and by utility companies. The effective collection and use of this information can minimize utility-related impacts and delays resulting in savings to DOTs and utility companies alike. The objective of this synthesis is to document current state DOT practices related to utility as- built data collection, use, and management. The synthesis will address as-built utility data for both subsurface and above ground utilities. Information to be gathered includes (but is not limited to): (1) Approaches to accessing utility company records and information (e.g., non-disclosure agreements, partnering agreements). (2) Types of records collected (e.g., paper versus digital) and what is included in the records collected (e.g., type of utilities, age of utilities, accuracy of location); (3) Approaches taken by DOTs in working with utility companies for sharing utility as-built information; (4) Use and management of utility data repositories and 3-D utility as-built information (e.g., data storage issues, retention policies; keeping the information current); (5) Technology used and accuracy standards for surveying or collecting as-built information (e.g., mapping grade versus survey grade collections); (6) Uses of utility as-built information in planning, project development, construction, or maintenance operations; and (6) Metrics used for quantifying the benefits realized by using utility as-built information during planning, project development, construction, and maintenance (e.g., SUE and utility conflict matrices, less delay, change orders).
