As requested, a <br /> representative of our firm performed field density testing at the site on May 8, 2002. Six tests <br /> were taken by the nuclear probe test method on pipe backfill. A sample of the material tested was <br /> brought to our laboratory for determination of the maximum density-optimum moisture content. <br /> The test results, summarized on the attached table, conform to the compaction requirements of <br /> the project specifications. <br /> We have employed accepted engineering and testing procedures. However, we do not undertake <br /> the guarantee of construction, nor do we relieve the contractor of his primary responsibility to <br /> produce a completed project conforming to the project plans and specifications. <br /> If you have any questions about this report,please call our office. <br /> Respectfully submitted, <br /> KLE=EDER, <br /> Ron Heinzen, G.E. <br /> Senior Principal <br /> REL:lr <br /> Attachment <br /> ST02RO33 ©2002 Kleinfelder,Inc. <br /> K' 'iii"'' 7).17 2825 ':a.,"iV,tie STVE6i, i)!( ' :icr ,L"". �i`�J'.7'� n- -) i <br />
