2. If Clay Plug Material is too dry, add water to material by sprinkling, then <br /> mixing or discing to make moisture content uniform throughout lift. <br /> 3. Do not attempt to compact Clay Plug Material that contains excessive <br /> moisture. Aerate material by blading, discing, harrowing, or other methods, <br /> to hasten drying process. <br /> D. Field Quality Control <br /> 1. As the clay plug material 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. Holes left by sampling and testing shall be backfilled by the EARTHWORK <br /> CONTRACTOR using the Clay Liner Material. <br /> 3. If acceptance testing by the QA/QC CONSULTANT indicates that the Clay <br /> Plug 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 /> E. Protection: <br /> 1. The clay plug shall be protected from any contamination which increases <br /> the hydraulic conductivity. Any contaminated material shall be removed <br /> and replaced at no cost to the OWNER. <br /> 3.11 COARSE GRAVEL MATERIAL <br /> A. General Requirements: Coarse Gravel shall be placed around leachate collection <br /> pipe and in sump area as shown on the Construction Drawings and should be fully <br /> encapsulated by geotextile. <br /> B. Coarse Gravel Placement: <br /> 1. The HDPE geomembrane lining underlying the Coarse Gravel shall be <br /> inspected and approved prior to placement of the Coarse Gravel. <br /> Is <br /> Forward Landfill WMU FU-04 <br /> 02300 18 EARTHWORK <br />
