2000-2999). No test number can be repeated for a given soil segment, and re -tests of failing tests <br />must be given a letter suffix along with the original test number (i.e., re -tests for a failing Test #1201 <br />would be: 1201A, 1201B, etc.). Test data and results must be filled out on the field density test <br />form. <br />3.3.2 Test Locations <br />The intent of the CQA program is to provide confidence that the earthwork materials and work <br />conform to the technical specifications. To meet this intent, the QA/QC Inspector will perform <br />density tests of earthfills, clay liner, and any other soil products used during construction. Density <br />tests must be located at various elevations and uniformly dispersed throughout the entire plan <br />dimensions of the fill. Density test locations must be chosen without bias; however, additional <br />testing can be performed in any areas that are suspect, marginal, or appear to be of poor quality. <br />During the progress of the work, density test locations will be plotted on a drawing by the QA/QC <br />Inspector to verify that no significant areas are untested. The drawing becomes part of the CQA <br />report. <br />3.4 Monitoring and Testing Requirements <br />Earthwork components of the construction are summarized in Paragraph 3.1 of this section. Each <br />component has specific construction requirements that must be monitored. The following sections <br />list monitoring requirements for each type of earthwork. <br />3.4.1 Stockpiling and Soil Management 0 <br />• Review Contractor's approved work plan submittal. Verifying stockpile locations, <br />stockpile dimensions, haul routes, material segregation procedures, and erosion, sediment <br />and drainage control measures. Determine and note corrective action items, if applicable. <br />During excavation, hauling, and stockpiling operations continually identify and verify <br />material classifications in accordance with ASTM D2478 and ASTM D2488 as necessary <br />to characterize material stockpile designations. Work closely with Contractor's quality <br />control personnel to classify materials using the rapid field tests described in ASTM <br />D2488. <br />Verify that stockpiles are constructed with slopes no greater than two horizontal to one <br />vertical and that the top surface maintains a minimum 5 percent grade. Verify slopes and <br />grades using hand held levels and inclinometers, range poles, and measuring tapes. <br />3.4.2 Excavations <br />• Verify that construction staking is performed before work and that survey bench marks <br />with elevations are secured outside the work area. <br />• Verify that excavated materials are segregated into proper stockpiles. <br />Page 20 0 <br />
