In San Jose at a high-profile technology campus, 15,000 sq foot of underground utility locating was conducted before trees could be removed in a designated area. Penhall Technologies executed the utility locating with the use of the GSSI 400Mhz antenna and the RD7100.
GPR used to provide a full underground utilities image as well as scan concrete to prepare for concrete cutting
A large general contractor with extensive experience in commercial construction in both the private and public sectors needed trained, proven GPR analysts. Because they had high regard for Penhall, it was clear to them that we were the ones for the job.
The general contractor accepted the daunting task of creating a full underground utilities image after they had already built the building for a new dining facility at the Presidio of Monterey. The GPR analysts needed perform utility scanning and mapping as well as structure scan the slab where the contractors deemed it necessary to saw cut and make needed repairs. Penhall worked hand in hand with the mechanical subcontractor in creating a “red line” drawing of the facility. After using several types of equipment to scan the slab as well as perform a sweep for utilities, Penhall was able to exceed the expectations of the client by not only locating, but also marking the suspected utilities. The full scan was completed in a non-destructive manner, and the contractors were happy to move forward with the project safely.
