TECHNICAL SPECIFICATIONS <br />SECTION 02776.2 <br />GEOSYNTHETIC CLAY LINER (GCL) <br />PART 1 - GENERAL <br />1.1 SUMMARY <br />A. This SPECIFICATION covers the technical requirements for the furnishing and installation of the <br />geosynthetic clay liner described herein. All materials used shall meet the requirements of this <br />SPECIFICATION, and all Work shall be performed in accordance with the procedures provided herein <br />and the DRAWINGS. All procedures, operations, and methods shall be in strict compliance with the <br />SPECIFICATIONS, Construction Quality Assurance Plan, and the DRAWINGS. <br />1.2 RELATED SECTIONS <br />A. Section 01400.2 — Geosynthetics Construction Quality Assurance (CQA) Plan. <br />B. Section 02200.0 — Earthworks. <br />C. Section 02776.1 — Geomembrane. <br />1.3 DEFINITIONS <br />A. Geosynthetic Clay Liner (GCL) - A manufactured hydraulic barrier consisting of clay bonded to a layer <br />or layers of geosynthetics. <br />B. Geomembrane — An essentially impermeable geosynthetic composed of one or more geosynthetic <br />sheets. <br />C. Geotextile — Any permeable geosynthetic comprised solely of textiles. <br />D. Minimum average roll value for geosynthetics — the value calculated as the typical value minus two (2) <br />standard deviations from documented quality control test results for a defined population from one <br />specific test method associated with one specific property. <br />E. Overlap — Where two adjacent GCL panels contact, the distance measuring perpendicular from the <br />overlying edge of one panel to the underlying edge of the other. <br />F. Typical value — The mean value calculated from documented Manufacturing Quality Control (MQC) <br />test results for a defined population obtained from one test method associated with one specific <br />property. <br />1.4 SUBMITTALS <br />A. CONTRACTOR shall provide the following information relating to the GCL MANUFACTURER <br />with its proposal: <br />1. Conceptual description of the proposed plan for placement of the GCL panels over the area of <br />installation. <br />2. GCL MANUFACTURER'S MQC Plan <br />3. A copy of GCL MANUFACTURER'S International Organization for Standardization (ISO) <br />quality certificate of registration. <br />4. GCL MANUFACTURER'S historical data for reinforced GCL including: <br />a. 10,000 -hour creep shear testing. <br />Geosynthetic Clay Liner (GCL) August 28, 2013 <br />02776.2-1 Revision 0 <br />S \Protects \1550 - CC &V Field Slit CQA PSES Bldg \8 0 Project Engineering and Design \8 2 Specifications\PSES Pipe Rack Liner Extension Specifications \02776 2 Geocomposite Clay <br />Liner docx <br />
