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 /> <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 /> <br />The QA/QC Inspector selects the locations from where seam samples will be cut for destructive <br />laboratory testing as follows: <br /> <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 /> <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 /> <br />The QA/QC Inspector will not inform the Geosynthetics Contractor in advance of selecting the <br />destructive sample locations. <br /> <br />The Geosynthetics Contractor will remove specimens and samples at locations identified by <br />the QA/QC Inspector and field test the specimens for peel and shear before the samples are <br />shipped off-site for laboratory testing. During sampling procedures the QA/QC Inspector <br />will: <br />
