Los Angeles Concrete Scanning Projects that Penhall Worked On

Penhall Technologies identifies safe areas to core

Penhall Technologies was hired at a project in Los Angeles for concrete scanning. The service was needed to complete core drill work to upgrade tenements for apartment residents. The analyst who performed the scanning noticed that the area being scanned was very congested with embedments. The analyst had to scan very carefully to identify all objects to ensure the customer avoided all embedments while directing the location of the proposed cores. The scanning was done with a Hilti PS 1000 and it showed rebar and multiple conduits. By having GPR scanning completed on this project, it allowed the customer to identify clear areas to core, saving them time and money and keeping everyone safe!

Concrete scanning performed on a regular basis for one large project in downtown los angeles

concrete scanning in los angeles, caFor an ongoing project with a large general contracting company at an up and coming luxury high rise condominium construction site in downtown Los Angeles, Penhall Technologies had yet another scanning project to add to the many scan jobs at this particular site over the past year. In this case, the general contractor needed to relocate dowels for rebar, to erect a CMU structure in an outdoor garden area. Before drilling they needed to locate rebar and any conduits that were in the slab. This work was performed using a GSSI Mini XT, a Hilti PS1000 and a RD7000 (radio detection device that picks up live electric). Penhall makes use of different tools to ensure better accuracy on each project.

Ground penetrating radar equipment used to identify hazards before cutting

Penhall went out to a location in Hollywood, CA to do some concrete scanning using Ground Penetrating Radar. We successfully identified any hazards and avoided them when the concrete was cut.

Locating electrical conduit within a concrete slab

Locating electrical conduit within concrete slab
As you may know, all hospitals require scanning before doing anything at all to the concrete in the building. So, it was a good idea for a medical center located in Los Angeles, CA to hire Penhall to complete a scanning. Here, our analysts were able to locate and mark conduit before cutting into the concrete.

Using GPR to locate rebar and conduit in CMU wall

CMU wall scan to locate rebar and conduit
At a jobsite in Los Angeles, CA, we were tasked with scanning a CMU wall to locate any obstructions, including structural reinforcements and any utilities, in two areas before coring 12″ x 6′ holes.

Rebar and any obstructions in concrete are accurately marked

Ground penetrating radar finds rebar before drilling
Ground penetrating radar scanning was used at a site in Los Angeles, CA to examine two different areas that were 33′ x 33′. Penhall performed the concrete scanning in order to avoid rebar before having 4″ to 6″ diameter cores drilled.
