Synthesis of Information Related to Highway Practices. Topic 52-05. Implementation of Subsurface Utility Engineering for Highway Design and Construction

Many state departments of transportation (DOTs) have implemented some level of subsurface utility engineering (SUE) as part of their project development and utility coordination processes. SUE is standardized by the American Society of Civil Engineer’s CI 38-02 “Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data.” This standard, while currently being revised, has been instrumental in ensuring more uniform practice of SUE since its development in the 1980s. Nevertheless, DOT implementation has varied considerably with respect to when different quality levels are implemented and how the data collected is integrated into plans and contract documents. DOT engineers and contractors have been using or soliciting their own SUE studies to mitigate utility conflicts and minimize utility strikes during construction. Contractors sometimes request quality level “A” data (potholing) in areas of utility congestion or where risk of dig-in events are high. The objective of this synthesis is to document DOT use and practices related to SUE. The synthesis will examine how DOTs use SUE and when SUE is used in the design and project delivery process. Information will be collected via literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
