n 3. If the clay liner becomes softened due to moisture changes, scarify and mix full depth of damage, adjust water content to specified value, and recompact as previously specified, at the EARTHWORK CONTRACTOR's sole expense. F. Field Quality Control 1. As the clay liner is being placed and compacted, the QA/QC CONSULTANT will be monitoring the construction activities and soil properties as described in the CQA Manual. Acceptance testing frequencies are defined in the CQA Manual. The EARTHWORK CONTRACTOR shall cooperate with the QA/QC CONSULTANT in obtaining samples for the CQA acceptance testing, and in leveling and backfilling areas designated by the QA/QC CONSULTANT. 2. The location of acceptance testing shall be determined solely by the QA/QC CONSULTANT. The QA/QC CONSULTANT may test any lift of the clay liner at any time, location, or elevation. 3. Holes left by sampling and testing shall be backfilled by the EARTHWORK CONTRACTOR using the Clay Liner Material. 4. If acceptance testing by the QA/QC CONSULTANT indicates that the Clay Liner Material does not meet specified requirements for density, water content, or lift thickness, the EARTHWORK CONTRACTOR shall terminate material placement until corrective measures are taken at the EARTHWORK CONTRACTOR's sole expense. Corrective measures could include, but are not limited to, scarifying and recompacting of material or removal of material that does not meet the requirements of these Specifications. 5. If acceptance testing by the QA/QC CONSULTANT indicates that the Clay Liner Material does not meet specified requirements for particle size, classifications, plasticity, or hydraulic conductivity, then the Clay Liner Material which failed will be retested. If the second test results indicate failure to meet the specified requirements, the QA/QC CONSULTANT may order a design modification or the removal, disposal, and replacement of the unsuitable Clay Liner Material. 6. Clay Liner Acceptance: Final acceptance of the clay liner will be based on acceptance and control tests made on completed Work, on material samples taken from the completed layer, and the thickness as calculated from the top of subgrade and top of clay liner surveys. Acceptance testing for final acceptance shall be performed by the soil testing laboratory in accordance with these Specifications and the CQA Manual. G. Protection: 1. Do not route or allow construction traffic, except as necessary, on top of clay liner once material has been placed and compacted. 2. Constructed clay liner shall be maintained to meet the requirements of this Specification until final completion and acceptance of the Work. This shall include all measures to prevent erosion. During seasonal or other extended shutdowns, all exposed surfaces shall be protected as detailed in Article 3. 1, Forward Landfill WMU FU -06 02300 17 EARTHWORK
