5 KLEINFELDER <br /> 7 QA/QC TESTING AND MONITORING <br /> 7.1 GENERAL <br /> The construction monitoring and QA/QC testing of the foundation layer will be primarily <br /> performed by the SJDPW Engineer and Field Engineers. Kleinfelder will assist with this <br /> monitoring. Kleinfelder will perform all monitoring and QA/QC testing of the test pad <br /> and barrier layer of the final cover. This will include part time monitoring of barrier layer <br /> construction should CDPW forces perform construction. Should the SJDPW hire an <br /> outside earthwork contractor to construct the test pad and barrier layer, Kleinfelder will <br /> provide full time construction monitoring. This workplan is based on the estimate that <br /> SJDPW forces take 6 months to install the barrier layer, and that an outside earth work <br /> contractor using a larger equipment fleet would reduce the time to one month. <br /> 7.2 QA/QC TESTING <br /> The tests to be used are shown in Table 7-1. For the most part they are standard ASTM <br /> tests as shown. The Sealed Double Ring Infiltrometer (SDRI) test will be carried out using <br /> t a circular Kleinfelder modification of the Trautwein square SDRI. <br /> Table 7-2 shows the monitoring test methods. This table outlines the construction <br /> observations in more detail and indicates the elements to be observed. <br /> Table 7-3 shows the frequency of field and laboratory testing and observations for both the <br /> Test Pad, and the final cover. <br /> Table 7-4 shows the pass/fail criteria for soil properties including moisture, density, <br /> `L percent passing #200 sieve and permeability. <br /> 7.3 CONSTRUCTION MONITORING <br /> Kleinfelder personnel will visit the site on each day that construction is in progress. The <br /> number of hours that Kleinfelder staff spend at the site each day will be determined by the <br /> F rate of progress of the construction work. The Kleinfelder QA/QC technician will perform <br /> L01 <br /> CR9-42 Page 23 of 28 <br /> Copyright 1991 Kleinfelder, Inc. <br /> L <br />
