Removing Barriers to Sharing Subsurface Utility Engineering (SUE) and Digital As-Built Data (DAB) between Utility Companies and State Departments of Transportation (DOT)

State departments of transportation (DOT) and utility companies traditionally have not shared data due to (1) limited technology allowing data captured on paper and stored in CAD to be easily exchanged, and (2) the risks and concerns about the liability of sharing data that may not be accurate and/or may change in the future. New geospatial technologies are being implemented by state DOTs and utility companies for internal purposes, but they have not been deployed to exchange data. Additionally, utility companies have concerns about controlling access to their location data related to security and exposure to competitors. Significant research has been conducted to document and quantify the negative impact and cost from utility conflicts and the lack of data sharing between utilities and DOTs and strategies. Much of this research was performed under the Second Strategic Highway Research Program (SHRP2) R15B, “Identification of Utility Conflicts and Solutions,” which examined best practices and tools to mitigate these costs and conflicts. Additional research identified through NCHRP Project 20-07 Task 418, “An Impact and Value Analysis of Requiring Geospatial Locations for Utility Installation As-Builts,” published a report that quantified the benefits of sharing geospatial utility as-builts and the barriers to collecting this data. This research proposes to focus on the utility perspective to define the benefits that utility companies will receive and overcome their perceived risks and liability. The objective of this research is to provide a framework for implementing a mutually beneficial mechanism to exchange geospatial asset location data between utility companies and state DOTs including subsurface utility engineering (SUE) data and digital as-built (DAB) data.
