Ground Penetrating radar used to locate post tension cables before drilling to relocate electrical conduits

concrete scan to locate post tension cableAt a new apartment complex in Auburn, at the top level of the parking deck below, the electrical contractors had unintentionally ran the main electrical feeds to a large switch panel in the wrong location and needed to be relocated a few feet. Since the slab has post tension cables in it Penhall Technologies was called upon to locate them in the slab so that the contractor could relocate the conduits without any further, and much more expensive, structural damage. Upon arrival I first noticed the electrical room is close to the exterior of the building, meaning the cables begin to expand and lay flat very close to the necessary location. Using ground penetrating radar, the GPR Analyst was able to quickly identify their location, find there were no utilities in the area and locate safe areas for the drilling contractor to set anchors without fear of damage. All of this was accomplished in one hour saving the contractor from more frustration, time and money. This particular jobsite has ran into numerous issues not foreseen during the build and Penhall Technologies has been with them to help every step of the way with 0 hits to date. Next time your job doesn’t go as planned remember Penhall Technologies for fast, professional and accurate service!
