• Verify that all repairs are completed and tested in accordance with the Specifications. <br /> • Record all completed and tested repairs on a repair sheet, and the panel layout drawing. <br /> Destructive Seam Sampling Procedures and Field Testing. Destructive seam samples will be <br /> taken at intervals of at least one test per 500 linear feet of geomembrane seams. However,additional <br /> samples will be taken if the QA/QC Inspector suspects that a seam does not meet the Specification <br /> requirements. Reasons for taking additional samples may include, but are not limited to: <br /> • Wrinkling in seam area <br /> • Excess crystallinity <br /> • Suspect seaming equipment or techniques <br /> • Weld contamination <br /> • Insufficient overlap <br /> • Adverse weather conditions <br /> • Failing tests <br /> The QA/QC Inspector selects the locations from where seam samples will be cut for destructive <br /> laboratory testing as follows: <br /> • A minimum of one test per 500 feet of seam length. This is an average frequency for the <br /> entire installation; individual samples may be taken at greater or lesser intervals. The <br /> testing frequency will be increased if welding operations were conducted in temperatures <br /> below 400F. This increase will be agreed upon by the Construction Manager, QA/QC <br /> Manager, and Geosynthetics Contractor. <br /> • A maximum frequency must be agreed to by the Construction Manager, QA/QC <br /> Manager,and Geosynthetics Contractor at the pre-construction meeting. However,if the <br /> number of failed samples exceeds 5 percent of the tested samples,this frequency may be <br /> increased at the discretion of the QA/QC Manager. Samples taken as the result of failed <br /> tests do not count toward the total number of required tests. <br /> The QA/QC Inspector will not inform the Geosynthetics Contractor in advance of selecting the <br /> destructive sample locations. <br /> The Geosynthetics Contractor will remove specimens and samples at locations identified by the <br /> QA/QC Inspector and field test the specimens for peel and shear before the samples are shipped off- <br /> site for laboratory testing. During sampling procedures the QA/QC Inspector will: <br /> • Observe sample cutting. <br /> • Mark each specimen and sample with an identifying number which contains the seam <br /> number, destructive sample test number, welder, and date and time welded. <br /> Page 31 <br />
