0 <br />• Verify that equipment operators are fully trained and qualified to perform their work. <br />• Verify that test equipment meets Specifications. <br />• Verify the entire length of each seam is tested in accordance with the Specifications. <br />• Observe all continuity testing and record results on the panel/seam log, and the panel <br />layout drawing. <br />• Verify that all testing is completed in accordance with the Specifications. <br />• Identify any failed areas, by marking the area with a waterproof marker compatible with <br />geomembrane, inform the Geosynthetics Contractor of any required repairs, and record <br />the repair on the panel/seam log. <br />• 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.
