Depth Approximations and Utility Mapping
An international engineering and construction company contracted Target to locate electrical duct banks associated with recently installed navigation lighting towers. Target used EMI/GPR technologies to determine the horizontal location and approximate depth of the electrical duct banks in specific areas. GPR and GPS data was collected in the field, analyzed and interpreted in the computer lab. A summary report was prepared with site specific maps, GPR cross sections, associated data tables and photographs.
