Sacramento Utility Locating Projects that Penhall Worked On

Verify existing utility markings with Penhall

Penhall Technologies was needed to perform a utility locate in San Carlos, California. This job consisted of performing verification of existing markings, as well as finding utilities that had never been marked and mapped. Our analyst performed a locate for power, telecommunications, and water. The analysts used the GSSI three-wheeled cart in conjunction with the RD 7000. Penhall was able to locate several unmarked targets as well as verify others.

Locate all communication lines with EM technology

Penhall Technologies was contracted to locate two 6″ existing communication lines coming out of a building. The client had lost as builts and communication line routes. Penhall Technologies located 1463′ of line from building to building. The method used to locate these two lines was electromagnetic detection with the RD7100. For this job, GPR was not able to collect data in the rough terrain. Penhall Technologies Private Utility Locating services comes prepared with both EM and GPR technologies to ensure all utilities are successfully located.

Penhall Technologies locates electrical and water lines

Recently, Penhall Technologies performed private utility scanning for an engineering firm. The client was working in the demolition and upgrade of large diesel fuel tanks. These provide power to air traffic control relay stations for the Federal Aviation Administration (FAA). Penhall Technologies had to locate any major electrical and water lines in the area. The analyst mapped out any of the grounding grids that were running through the area. This allowed the demolition process to be sped up, keeping the project ahead of schedule and on budget.
