C <br />C <br />measurements at intervals over the entire test duration. <br />PART 3 EXECUTION <br />3.1 PLACEMENT OF GEOCOMPOSITE <br />A. Place and anchor the Geocomposite in the manner and at the locations shown on <br />the Construction Drawings and as directed by the QA/QC CONSULTANT. Place <br />Geocomposite with the long dimensions downslope, unless otherwise directed by <br />the DESIGN ENGINEER. Install Geocomposite smooth and free of tensions, <br />stress, folds, wrinkles, or creases. <br />B. Secure, leak -proof bags of sand shall be used to secure the Geocomposite during <br />installation. Securing pins shall not be used. Sandbags that are placed on the <br />Geocomposite at the base of the slope shall be removed by the EARTHWORK <br />CONTRACTOR immediately prior to placement of the overlying granular <br />drainage material. The sand bags shall be removed from the cell or placed above <br />the protective operations layer and shall not be left within the granular drainage <br />material layer. <br />C. Care shall be taken to keep the Geocomposite clean and free from debris prior to <br />installation. If Geocomposite is not free of soil and debris before installation, it <br />shall be cleaned by the GEOSYNTHETICS CONTRACTOR just prior to <br />installation. <br />D. Lay Geocomposite to ensure that runouts at terminations and tie-ins are placed to <br />the minimum dimensions shown on Construction Drawings. Place Geocomposite <br />in anchor trench at top of slope to the minimum dimensions shown on <br />Construction Drawings. <br />3.2 JOINTS <br />A. Horizontal Joints: No horizontal joints will be permitted without prior approval <br />of the DESIGN ENGINEER. <br />B. Vertical Joints: Geocomposite panels shall be laid smooth to provide a minimum <br />width of 4 inches of geonet overlap for each vertical joint. Geonet vertical joints <br />shall be tied at 5 -foot intervals using a method approved by the QA/QC <br />CONSULTANT. Plastic ties or tying materials shall be of contrasting color to the <br />Geocomposite panels for inspection. Metallic connectors shall not be allowed. <br />C. Sewn Seams: The geotextile component of the Geocomposite shall be joined by <br />sewing continuously. <br />1. Seam Efficiency: <br />a. Minimum 70 percent. <br />b. Tested according to ASTM D4884. <br />FORWARD LANDFILL WMU FU -06 GEOCOMPOSITE <br />02774 7 DRAINAGE NET <br />
