UMS presents at the 2016 Excavation Safety Conference and Expo in Las Vegas

Don Haines and Jerry Davis with UMS were presenters at the 2016 CGA Excavation Safety Conference and Expo in Las Vegas, NV March 8th through the 11th. Don’s presentation “Application of 3-D Utility Surveying and Design for Puget Sound Energy’s SR-510 Gas Pipeline Project” describes an incredible effort in Washington State where Puget Sound Energy needed to find an opening for their proposed 8-inch high-pressure gas main within a mile-long utility congested corridor in a WSDOT roadway segment. Approximately 100,000 linear feet of existing utilities were mapped using GPR, Spar 300 and/or test holes. Creation of a 3D CADD drawing in MicroStation was used as a reference file depicting all collected existing utility information. After conflict analysis, via 3D modeling, an alignment was then identified for the gas main to be constructed with minimal risk. Jerry’s talk discussed Northwestern Energy’s (NWE) pilot program in Montana of monitoring third-party excavation activities that have the potential to cross gas distribution lines 2 inches and greater in diameter. Standby projects were implemented by NWE personnel in the Flathead county (est pop. 95,000) and by UMS personnel in Lewis and Clark county (est pop. 65,000). Indications are that when representatives of a utility company are onsite to educate excavators and monitor excavation activities, incidents of third-party damage to their gas distribution systems drop.
