• 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 Inspgctor 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.
