When HW Davis Construction of Orlando, FL needed to add electrical floor boxes at the Orlando International Airport without hitting any electrical conduits they contacted GPRS, Inc of Orlando, FL. HW Davis has an ongoing project renovating a section of the TSA Inspection point at the airport. Part of the scope of work is relocating the X-Ray machines and each machine needs its own electrical box in the floor. HW Davis planned to make several two inch penetrations in the concrete to run electrical conduit to the floor boxes. In doing this they wanted to make sure they would not strike an existing electrical conduit already in the concrete. Thus they contacted the Florida area ground penetrating radar specialists, GPRS. This is an ideal application for ground penetrating radar as electrical conduit and rebar locating are GPR specialties. GPRS, Inc. from Orlando, FL took the call and mobilized to the site.
On site GPRS was able to identify all reinforcing steel and potential electrical conduits quickly and accurately. They marked all of them on the surface and then GPRS, based on the data, determined the best places to drill to avoid striking an electrical conduit. The project was a success and radar once again proved its usefulness on concrete for locating rebars and electrical conduits.
Chris Moore runs GPRS operations in the South Eastern United States. He is based in Orlando, FL and he can be reached at (727)420.3292 or by email at chris.moore@gp-radar.com. Concrete scanning for the purposes of identifying the location of rebar and electrical conduit is a frequent service performed by the GPR technicians at GPRS.
