Final Construction Quality Assurance Report— WMU FU -13 <br />Forward Landfill <br />• 5.6 GEOGRID <br />5.6.1 General and Receiving Inspection <br />A geogrid layer was placed below the geomembrane on the top deck area of WMU FU -13. The <br />MQC certifications and conformance test results for this material were reviewed and approved <br />and the documentation for these rolls is included in this Report. <br />5.6.2 Receivinp, Inspection <br />Upon arrival by truck, GLA's CQA Monitor observed the unloading and storage of each roll of <br />geogrid. Each roll of geogrid was recorded in the Receiving Logs by roll number and <br />crosschecked against the manufacturer's quality control documents (MQC certificates) provided <br />by the manufacturer. Following inspection of the rolls and review of the MQC certificates, the <br />material was approved for deployment. A copy of the Geogrid Receiving Log and the <br />manufacturer's quality control data are included in Appendix M. <br />5.6.3 Conformance Testing <br />Select samples of the geogrid were cut from random rolls at the manufacturing plant by the <br />• third party testing laboratory, TRI, for conformance testing in accordance with the project <br />specifications and CQA manual. Conformance testing included: <br />Wide Width Tensile Strength (ASTM D-6637). This testing was later modified per the <br />design revisions provided in Appendix A <br />A total of 1 geogrid sample was tested for conformance. Based on 68,000 ft2 of geogrid <br />received, this testing frequency corresponds to one test per 68,000 ft2 which satisfies the <br />requirement of one test per 100,000 ft2. Results of the conformance testing indicated that the <br />materials met the requirements of the project specifications. Detailed test results are included <br />in Appendix M. <br />5.6.4 Deployment <br />The panel deployment procedure was observed and documented by GLA's CQA Monitor. The <br />CQA monitor observed that the conditions for deployment described in the CQA Manual were <br />followed during deployment of the geogrid materials. GLA's CQA Monitor continuously <br />observed deployment. <br />• The seam overlap, seaming, tie-ins, and other manufacturer's written guidelines were followed. <br />29 Geo-oyic <br />A S S O C I A T E S <br />
