<br /> <br /> Forward Landfill WMU FU-23 02300 16 EARTHWORK <br /> E. Maintaining Clay Liner Condition: <br /> <br /> 1. Following completion of the clay liner, it shall be maintained in a moist <br />condition by sprinkling with water or covering with plastic sheeting until <br />the overlying components of the liner system are placed. The <br />EARTHWORK CONTRACTOR shall be responsible for, and shall repair <br />and replace at his own expense, any portion of the clay liner that has dried <br />out or been damaged by unfavorable weather conditions or by his <br />construction operations. <br /> 2. Cracks that form in the hydraulic barrier layer shall be repaired. Repair <br />shall consist of mixing to the full depth of the crack, moisture conditioning, <br />and recompacting to the same relative compaction as the surrounding clay <br />liner at the EARTHWORK CONTRACTOR's sole expense. <br /> 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 <br />recompact as previously specified, at the EARTHWORK <br />CONTRACTOR's sole expense. <br /> <br /> F. Field Quality Control <br /> <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 <br />designated 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 <br />EARTHWORK 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 <br />may order a design modification or the removal, disposal, and replacement <br />of the unsuitable Clay Liner Material. <br /> 6. Clay Liner Acceptance: Final acceptance of the clay liner will be based on
