The city of Pittsburgh looked to Master Locators to provide private utility locating services on the Northeast corner of 39th Street and Butler Street. We performed ground penetrating radar to provide an electronic sketch of subsurface utilities and also marked out utilities and possible underground septic tanks (USTs).
How We Did It
We sent a service technician to the Steel City to locate underground utilities. Our technician started this project with a passive scan on the radio setting, in which he detected an unmarked unknown line for approximately 42 feet. We were able to directly connect to the water valve in the sidewalk and detected the inconsistent signal leading into the road. We, then, were able to confirm the previous mark outs and marked possible locations of Underground Septic Tank’s that were believed to be present onsite. Of the boreholes we scanned, there were no detectable utilities in their vicinities.
