Excavation damage is one of the most significant threats to the integrity of underground utility assets. Some utility lines cannot be detected with standard locating tools, so researchers are exploring new applications of Radio Frequency Identification (RFID) technology to enhance utility locating operations. On Oct. 16-17, 2012, Gas Technology Institute (GTI) hosted a workshop to share the successful outcomes of the three-year Virginia Department of Transportation (VDOT) RFID marker ball technology program to prevent excavation damage on highway projects. Funding for the workshop was provided by Operations Technology Development (OTD), a partnership of natural gas distribution companies formed to develop, test, and implement new technologies. 3M and Utility Sales Associates also provided support for the workshop.
