We appreciate the opportunity to work with you. If you have questions <br /> regarding the results of this scanning, please contact the lead GPRS technician on this project. <br /> EQUIPMENT USED <br /> The following equipment was used on this project: <br /> • Underground Scanning GPR antenna.Typically capable of detecting objects up to 8' deep or more in ideal conditions <br /> but maximum effective depth can vary widely and depends on site and soil conditions. Depth penetration is most <br /> commonly limited by moisture and clay/conductive soils. Depths provided should always be treated as estimates as <br /> their accuracy can be affected by multiple factors. <br /> • Electromagnetic Pipe and Cable Locator. Detects electromagnetic fields. Used to actively trace conductive pipes and <br /> tracer wires, or passively detect power and radio signals traveling along conductive pipes and utilities. Depths <br /> provided should always be treated as estimates as their accuracy can be affected by multiple factors. <br /> Work Performed <br /> Ground Penetrating Radar Systems performed the following work on this project: <br /> Underground Utility <br /> The scope of work included scanning the specified area to locate underground utilities. A tracer signal was sent along any <br /> accessible metallic utility or tracer wire, and the area was scanned with GPR to locate any additional targets.The locations <br /> of any detected utilities and anomalies were marked directly at the site with paint,flags, stakes, or other appropriate <br /> means, and results were reviewed with onsite personnel unless otherwise noted. <br /> • The scope of work included scanning the areas around proposed soil borings.A radius of approximately 10' around <br /> each proposed soil boring was scanned unless otherwise noted. A total of 3 boring locations were scanned. <br /> • Client will be drilling 3 vertical soil borings at the specified site address and needs utilities cleared prior to breaking <br /> ground. <br /> • The effective depth of GPR will vary throughout a site depending on surface and soil conditions. In this area,the <br /> maximum effective GPR depth was approximately 3 feet. <br /> Page 1 of 3 <br />
