Villanova University called Master Locators to help with a simple private utility locating job. We were able to mark out locatable utilities using ground penetrating radar (GPR). For this project, we provided the client with an electronic sketch and PMU of the manhole and street where we were able to scan.
How We Did It
Our service technician traveled to Villanova University and used a duct rodder and electromagnetic scanning (EM) to locate and mark out a duct bank. There was an empty conduit in the duct bank, which we accessed about 8 feet down inside a manhole. We put a duct rodder in the fiber optic conduit to find the possible location of the conduit.
As part of our seven steps of locating process, we also performed passive scans and used GPR to locate any unknown utilities that may have been in the area. When the work was completed, our technician walked the site with our client to show him where the conduit was running through the scope and, across the street, where we marked it out.
