3. If the clay liner becomes softened due to moisture changes, scarify and mix <br /> full depth of damage, adjust water content to specified value, and recompact <br /> as previously specified, at the EARTHWORK CONTRACTOR's sole <br /> expense. <br /> F. Field Quality Control <br /> 1. As the clay liner is being placed and compacted, the QA/QC <br /> CONSULTANT will be monitoring the construction activities and soil <br /> properties as described in the CQA Manual. Acceptance testing frequencies <br /> are defined in the CQA Manual. The EARTHWORK CONTRACTOR <br /> shall cooperate with the QA/QC CONSULTANT in obtaining samples for <br /> the CQA acceptance testing, and in leveling and backfilling areas designated <br /> by the QA/QC CONSULTANT. <br /> 2. The location of acceptance testing shall be determined solely by the QA/QC <br /> CONSULTANT. The QA/QC CONSULTANT may test any lift of the clay <br /> liner at any time, location, or elevation. <br /> 3. Holes left by sampling and testing shall be backfilled by the EARTHWORK <br /> CONTRACTOR using the Clay Liner Material. <br /> 4. If acceptance testing by the QA/QC CONSULTANT indicates that the Clay <br /> Liner Material does not meet specified requirements for density, water <br /> content, or lift thickness, the EARTHWORK CONTRACTOR shall <br /> terminate material placement until corrective measures are taken at the <br /> EARTHWORK CONTRACTOR's sole expense. Corrective measures <br /> could include, but are not limited to, scarifying and recompacting of <br /> material or removal of material that does not meet the requirements of these <br /> Specifications. <br /> 5. If acceptance testing by the QA/QC CONSULTANT indicates that the Clay <br /> Liner Material does not meet specified requirements for particle size, <br /> classifications, plasticity, or hydraulic conductivity, then the Clay Liner <br /> Material which failed will be retested. If the second test results indicate <br /> failure to meet the specified requirements, the QA/QC CONSULTANT may <br /> order a design modification or the removal, disposal, and replacement of the <br /> unsuitable Clay Liner Material. <br /> 6. Clay Liner Acceptance: Final acceptance of the clay liner will be based on <br /> acceptance and control tests made on completed Work, on material samples <br /> taken from the completed layer, and the thickness as calculated from the top <br /> of subgrade and top of clay liner surveys. Acceptance testing for final <br /> acceptance shall be performed by the soil testing laboratory in accordance <br /> with these Specifications and the CQA Manual. <br /> G. Protection: <br /> 1. Do not route or allow construction traffic, except as necessary, on top of <br /> clay liner once material has been placed and compacted. <br /> 2. Constructed clay liner shall be maintained to meet the requirements of this <br /> Specification until final completion and acceptance of the Work. This shall <br /> include all measures to prevent erosion. During seasonal or other extended <br /> shutdowns, all exposed surfaces shall be protected as detailed in Article 3.1, <br /> Forward Landfill WMU FU-04 <br /> 02300 16 EARTHWORK <br />
