San Diego Utility Locating Projects that Penhall Worked On

1. Penhall locates utilities in an 8 mile path for Camp Pendleton

locate private utilities in San Diego CARecently, a general contractor in the San Diego area hired Penhall Technologies to locate all utilities in the dig parameters of an 8 mile path on the grounds of a Marine Corps base Camp Pendleton. The general contractor is installing a communications duct bank. The general contractor wanted to know the location of all of the utilities in the area prior to setting manholes, and the trenching for the communication lines. Penhall came in after a previous locating company had been called out. The general contractor had an uneasy feeling about their locates so they called Penhall. So far, 2 months into the job, Penhall has been able to locate a total of 16 lines, unmarked by the previous company, preventing catastrophic damage to high profile utilities and saving valuable time. The general contractor is so pleased with Penhall’s performance that we will be called upon until the completion of the project which could last into the month of June 2017. We used the SIR 4000 with a 400Mz antenna and the Electromagnetic Detection RD8000unit to direct connect onto all the utilities in direct conflict with the clients dig parameters. Penhall Technologies was able to exceed the expectations of the client by not only locating the utilities, by marking them out on the surface in real time using spray paint. The project was completed in a safe and non-destructive manner. Penhall Technologies of the San Diego, Ca area has the capability and the man power to meet your needs in a timely manner, ultimately ensuring your projects get finished safely and on time.
