Earth Technologies, Inc. was hired by Whiting-Turner Construction Company to perform excavation work for the construction of a new biology building at Yale University, New Haven, Connecticut. The sitework plans required that a ground penetrating radar (GPR) survey be performed prior to excavation to identify subsurface utilities and other anomalies. We performed a GPR survey of the entire site and determined the location and depth of all existing utilities, including several abandoned and unidentified lines not depicted on site plans. One of the unidentified lines detected during the survey was a water line Yale University maintenance personal did not know existed. Discovering the existence of this line saved them from spending an additional $100,000 for the installation of a new line.

“We used Underground Surveying to locate the underground utilities for an investigation project at the future site of the Yale Biology Building in New Haven, CT. The work was performed accurately, within budget and performed under tight schedule constraints. The data that was provided assisted the design team by confirming the locations and inverts of known existing utilities and by locating services that were unknown. I would use Underground Surveying again or recommend using them to anyone who has need of this specialty locating service.”
