If <br />GPR method proves to be having difficulty in resolving critical areas, X.Ray method is recommended. <br />• If GPR target lines physically marked on test area(s) by the technician are In conflict with the specified layout for saw cut, drilling and/or <br />coring operations, it is recommended that written approval is obtained from authorized client representative prior to commencement of any <br />saw cut, drilling and/or corIng operations. <br />• Client understands that GPR interpretations do not differentiate between rebar, conduit and/or PT cable. If client is requesting that these <br />elements must be positively identified, then X-Ray method shall be required. <br />• Rough surface conditions, obstructions in immediate GPR scanning area. high density wire mesh, weather proofing. or alr gaps between <br />structural concrete/masonry layers may impede or prohibit radar penetration. If such condition(s) exists alternative methods may be <br />necessary. <br />• If rebar size estimation is performed, results are subject to a tolerance of +/- 1 bar diameter. <br />• It is recommended that client stays 2" away from all targets marked. <br />• Signature below verifies technician(s) time onsite and services performed as per customer request <br />SEE ATTACHED PHOTOGRAPHS ON NEXT PAGE FOR DETAILS <br />Time In: 0730 Time Out: 1530 Total (Hrs): 24 Travel (Hrs): <br />Regular Time: 24 1.5X:2X: <br />t.>25- <br />Technician'* Signature Client Signatore <br />Continued on Next Page <br />Test Results provided by Inspection Resources, co are given in good faith and are usually accurate.
