Private Utility Locating Prior to Sign Install

A contractor based out of Denver recently contacted Ground Penetrating Radar Systems of Colorado to conduct a private utility locate. The contractor was planning to install roughly 40 signs, and prior to placing the caissons into the ground, the wanted to the job site scanned for utility lines. There was a lot of underground utilities running throughout the property that the general contractor did not know exactly where they were located and so they had GPRS come out to clear each one of these sign locations. With the technology that GPRS uses we were able to locate around each one of these locations so they could drill successfully and have no worries. We use an RD 7000 along with a transmitter to direct connect to a utility that emerges from the ground on one end and trace it to the other end. We also use a 400 MHz radar antenna to locate any unknown utilities in the area that do not emerge from the ground.

Along with marking all findings on the ground with either pin flags or paint, GPRS also offers a service of collecting all the findings with a GPS and putting it into a Google Earth overlay for future reference. We can typically have the google earth overlay to the customer in 3 to 4 business days.
