Santa Clara Utility Locating Projects that Penhall Worked On

Locate utility lines before construction

Recently, Penhall Technologies performed utility locating services at the San Jose Fairgrounds. The client wanted to scan before the directional boring of communication lines. Our analysts used the RD 7000 in power and radio mode, in addition to using an induced signal method. They located gas lines, power lines, communication lines, and water lines. Also, they used the GSSI 400 MHZ three-wheel cart to examine an approximate depth of 8-10 feet to locate other targets not located by the RD 7000 unit. After the scan, the analysts did a job walk with the customer to prevent any misunderstandings, and followed up with a field report.
