Austin Utility Locating Projects that Penhall Worked On

Penhall Technologies locates power lines during drilling

Penhall Technologies’ Austin Division was recently hired by a RV and Boat storage facility to locate multiple power lines. The lines provide electricity to each storage canopy and to the main entrance to the facility. The company was installing two new covered areas for more storage. The company drilling the footings told the Storage Facility that utility locating was not necessary. During drilling, the client hit the main power to the facility, as well as power to one of the canopies. At that point, the client contacted Penhall Technologies. The analyst was able to successfully locate 6 power lines leading across a 30 by 300 foot parking lot. He located the power lines using the GSSI Sir 4000 with a 400MHz antenna to scan the area and used a radio detection device (RD 7100).
