n <br />2. If Clay Plug and Clay Earthfill Material is too dry, add water to material by <br />sprinkling, then mixing or discing to make moisture content uniform <br />throughout lift. <br />3. Do not attempt to compact Clay Plug and Clay Earthfill Material that <br />contains excessive moisture. Aerate material by blading, discing, <br />harrowing, or other methods, to hasten drying process. <br />D. Field Quality Control <br />1. As the material is being placed and compacted, the QA/QC CONSULTANT <br />will be monitoring the construction activities and soil properties as <br />described in the CQA Manual. Acceptance testing frequencies are defined <br />in the CQA Manual. The EARTHWORK CONTRACTOR shall cooperate <br />with the QA/QC CONSULTANT in obtaining samples for the CQA <br />acceptance testing, and in leveling and backfilling areas designated by the <br />QA/QC CONSULTANT. <br />2. Holes left by sampling and testing shall be backfilled by the EARTHWORK <br />CONTRACTOR using the Clay Plug and Clay Earthfill Material. <br />3. If acceptance testing by the QA/QC CONSULTANT indicates that the <br />material does not meet specified requirements for density, water content, or <br />lift thickness, the EARTHWORK CONTRACTOR shall terminate material <br />placement until corrective measures are taken at the EARTHWORK <br />CONTRACTOR's sole expense. Corrective measures could include, but are <br />not limited to, scarifying and recompacting of material or removal of <br />material that does not meet the requirements of these Specifications. <br />E. Protection: <br />1. The clay plug and clay earthfill shall be protected from any contamination <br />which increases the hydraulic conductivity. Any contaminated material <br />shall be removed 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 />Forward Landfill WMU FU -06 <br />02300 <br />19 <br />EARTHWORK <br />
