Ground Penetrating Radar Systems of Michigan was recently hired by a Detroit area hospital to help locate electrical conduits or other unknown obstructions prior to saw cutting. Multiple areas of concrete floor were to be saw cut in order to repair a broken unit located in the mechanical room. Without any accurate site plans of what was in, or just below the concrete floor, the contractor decided to hire GPRS. The above pictures illustrate the multiple conduits that were located with GPR, all of which were located within the 6” concrete slab.
