Colorado Springs Projects that Penhall Has Worked On

Penhall finds gas line and other objects in homeowner’s backyard

Penhall Technologies was hired to locate private utilities for a homeowner in Colorado Springs. The client wanted to find a gas line hidden in his backyard. The main reason for the private utility locate was to make sure that his pool installation project was completed smoothly and without any extra delays or financial costs. The analyst scanned for utilities with a 400MHz antenna using the GSSI 4000 operating system. The analyst successfully located the gas line. To verify the findings, the analyst ran a scan using the RD 7100 and found some electrical lines running throughout the back yard for lighting originally thought to run the parameter of the yard. He also located several old tools and miscellaneous metal subsurface objects. The customer was able to avoid the gas line and have the electrical lines rerouted without injury or incident.

Penhall locates water line to prevent further damage during excavation

In this instance Penhall Technologies was asked by a general contractor to verify all private utilities surrounding a residence. The customer had a map that was supposed to show the locations of the utilities. However, when the contractor began excavating for an add-on to the residence, they hit a water line that was not laid out in the map. It is always advised to scan before excavating to avoid damage to any underground line. The analyst scanned the proposed area with the RD 7100 using the transmitter in unison with the wand. Using this equipment, the analyst was able to successfully locate all utilities. The results resolved why the water line that was hit was not on the map. Turns out that it was added later for irrigation that had since been capped and forgotten.
