• a minimum of one sample for each geomembrane seamer; <br />• a minimum of one sample every 500 feet of seaming; and <br />• seams that appear suspect to the CQA Monitor. <br />The CQA Monitor shall witness the testing of destructive seam samples by the INSTALLER. <br />The INSTALLER shall mark all samples with their roll and seam number, date, machine number, <br />welding technician identification, extruder and nozzle /wedge temperature, and ambient air <br />temperature. <br />The INSTALLER shall test all destructive samples in compliance with the project <br />SPECIFICATIONS. <br />The INSTALLER shall be responsible for patching all areas cut for test samples in accordance <br />with the SPECIFICATIONS and MANUFACTURER's requirements and performing non- <br />destructive testing (i.e., vacuum box) of the seams. The CQA Monitor shall record test locations <br />on the geomembrane defect log forms. Additional testing information will be recorded on the <br />geomembrane seam destructive sample log form. The CQA Monitor shall track failing tests as <br />described in the SPECIFICATIONS. <br />Repairs - The CQA Monitor shall observe and document that all repair materials, techniques, and <br />procedures used for repairs are approved in advance and meet the requirements of the project <br />SPECIFICATIONS. The CQA Monitor shall verify that all defects and repairs are marked, <br />recorded, repaired, tested, and wrinkles are addressed, prior to being covered by other materials; <br />and that repairs are performed as specified, including proper patch size or dimension. The CQA <br />Monitor shall record defects and repairs on the defect and repair log forms. <br />6.03.02 GEOTEXTILE: <br />During geotextile installation, the CQA Monitor shall observe and document deployment, field seaming, <br />and repairs to assure that the installation is in compliance with the SPECIFICATIONS. <br />Deployment - The CQA Monitor shall verify that the subgrade is free of deleterious materials <br />prior to deployment, anchoring is achieved as specified, specified methods are used to minimize <br />wrinkles and protect underlying layers during cutting of materials, and deployment procedures are <br />performed in compliance with the project SPECIFICATIONS. <br />Seams - The CQA Monitor shall verify sufficient overlap and that the specified seam procedures <br />were followed in compliance with the project SPECIFICATIONS <br />Repairs - The CQA Monitor shall verify that all repairs are performed in compliance with <br />SPECIFICATIONS. <br />Protection - The CQA Monitor shall observe and document that all soil materials placed on top of <br />the geosynthetics are done in such a manner as to ensure that the geosynthetics and underlying <br />materials are not damaged. <br />6.03.03 POLYETHYLENE PIPE AND FITTINGS: <br />During polyethylene pipe installation, the CQA Monitor shall observe and document that the installation is <br />in compliance with the project SPECIFICATIONS. CQA monitoring of the polyethylene pipe and fittings <br />will include the following: <br />Section 01400.2 Page 8 of 11 December 6, 2013 <br />Geosynthetic CQA Plan Revision 2 <br />SAProjects\1125M -CC &V Lab Liner Extension \H2 - Design \Lab Liner Extension \Cert Report\Cert 08.06.13Vappendix D Specifications \Individual Sheets \01400.2 2.doc <br />
