PROCESS <br /> The process typically begins with using the EM pipe locator to locate pipes or utilities throughout the scan area. First,the <br /> transmitter is used to connect to and trace any visible risers,tracer wires,or accessible,conductive utilities provided that there is an <br /> exposed,metallic surface. The areas are then swept with the receiver to detect live power or radio frequency signals. Locations and <br /> depths are painted or flagged on the surface. Depths cannot always be provided depending on the location method and can be <br /> prone to error. <br /> Initial GPR scans were then collected in order to evaluate the data and calibrate the equipment. Based on these findings,a scanning <br /> strategy is formed,typically consisting of scanning the entire area in a grid with 1 foot scan spacing in order to locate any potential <br /> utilities that were not found with the pipe locator. The GPR data is viewed in real time and anomalies in the data are located and <br /> marked on the surface along with their depths using spray paint, pin flags,etc. <br /> LIMITATIONS <br /> Please keep in mind that there are limitations to any subsurface investigation. The equipment may not achieve maximum <br /> effectiveness due to soil conditions,above ground obstructions,reinforced concrete,and a variety of other factors. No subsurface <br /> investigation or equipment can provide a complete image of what lies below. Our results should always be used in conjunction with <br /> as many methods as possible including consulting existing plans and drawings,exploratory excavation or potholing,visual inspection <br /> of above-ground features,and utilization of services such as One Call/811. Depths are dependent on the dielectric of the materials <br /> being scanned so depth accuracy can vary throughout a site. Relevant scan examples were saved and will be provided in this report. <br /> FINDINGS <br /> The subsurface conditions at the time of the scanning allowed for maximum GPR depth penetration of 2 feet in most areas. <br /> The following pages will provide further explanation of the findings. <br /> Page 2 of 8 <br />
