Keeping the job site safe with concrete scanning

job site safety with concrete scanning
We were called out to a jobsite in San Diego, CA to scan a concrete floor for potential hazards. Penhall always puts safety as a first priority before starting any scanning project and arrived prior to scanning for a safety site assessment and job walk. For this project we were asked to locate a fan coil for a client and after a thorough job walk we used our ground penetrating radar to scan a 4′ x 4′ area. In addition to locating the fan coil Penhall was tasked with locating additional metallic piping. This additional portion of the project necessitated scanning an area measuring 2′ x 15′.

Locating rebar and existing conduit within a concrete wall

Concrete scanning to find conduit
Many times, Penhall gets called to scan before drilling is to take place. In this particular job in San Diego, CA, we were asked to scan a concrete wall in preparation for a 10″ core drill. The client’s request was for us to locate conduit that may be existing in the wall. We were able to find the conduit and complete the work in a timely manner.

Locating conduit and utilites through concrete scanning
For this project in the San Diego area, we scanned a concrete slab on grade to locate existing conduit as well as post tension cables. This was in preparation for trench that would eventually be cut at a measurement of 24′ long x 1″ wide x4-6″ thick.

We mark all findings, including rebar, post tension cables, and utilities

GPR scanning to find rebar, post tension cables, and utilities
Penhall was called out to scan a structure in San Diego, CA. The scan request was to locate rebar, post tension cables, and utilities in the concrete slab. Before scanning we examined the job site thoroughly for any external hazards and exposed confirmations of live conduits including duct boxes. The GPR scanning was conducted on the 1st, 2nd, 3rd, and 4th floors of the structure. The four floors consisted of concrete slabs that were 9″ thick.
