kn KLEINEELDER 7 QA/QC TESTING AND MONITORING 7.1 GENERAL The construction monitoring and QA/QC testing of the foundation layer will be primarily performed by the SJDPW Engineer and Field Engineers. Kleinfelder will assist with this monitoring. Kleinfelder will perform all monitoring and QA/QC testing of the test pad and barrier layer of the final cover. This work plan is based on the estimate that an outside earth work contractor would require approximately one month to construct the barrier layer. 7.2 QA/QC TESTING The tests to be used are shown in Table 7-1. For the most part they are standard ASTM tests as shown. The Sealed Double Ring Infiltrometer (SDRI) test was, carried out on the test pad using a circular Kleinfelder modification of the Trautwein square SDRI. Table 7-2 shows the monitoring test methods. This table outlines the construction observations in more detail and indicates the elements to be observed. Table 7-3A shows the frequency of field and laboratory testing and observations for the final cover. Provided the contractor passes these required tests, for the initial 10 percent (10 acre) of the cover, the testing frequency will be reduced to that shown in Table 7-3B. Table 7-4 shows the pass/fail criteria for soil properties including moisture, density, percent passing #200 sieve and permeability. 7.3 CONSTRUCTION MONITORING Kleinfelder personnel will visit the site on each day that construction is in progress. The number of hours that Kleinfelder staff spend at the site each day will be determined by the rate of progress of the construction work. The Kleinfelder QA/QC technician will perform the necessary geotechnical tests or tasks in accordance with the Frequency of Testing schedule as set forth on Table 3. Test results and observations will be recorded on standard forms. An outline of Kleinfelder Standard Forms is given in Appendix C. A weekly report will be prepared which will summarize the results of testing for the previous week. This summary report will be prepared by the supervising technician or engineer and reviewed by the QA/QC officer. GSM:md 3EI94 Page 20 of 24 Copyright 1994 Kleinfelder, Inc.
