TECHNICAL SPECIFICATIONS <br />2. Do not deploy during precipitation, in the presence of excessive moisture (e.g. fog, dew), in an <br />area of ponded water, or in the presence of excessive winds. <br />Do not undertake deployment if weather conditions will preclude material seaming on same day as <br />deployment, unless approved by MANAGER, DESIGN ENGINEER, and CERTIFYING <br />ENGINEER.. <br />B. Seaming <br />Normal Weather Conditions: Normal seaming procedures may take place if the following weather <br />conditions exist: <br />a. Ambient temperature between 35° F and 100° F. <br />b. Dry conditions, i.e., no precipitation or other excessive moisture, such as fog or dew. <br />C. No excessive winds. <br />Adverse Weather Conditions <br />a. Do not seam if ambient temperature is below 14° F or above 100° F. <br />b. Do not seam during precipitation, in the presence of excessive moisture (e.g. fog, dew), in an <br />area of ponded water, in the presence of excessive winds. <br />C. If the ambient air temperature is between 35° F and 14° F for the entire shift, cold weather <br />seaming provisions will govern. <br />The INSTALLER will be required to perform a minimum of four trial seams during the planned <br />work shift, at approximately the same time interval throughout the scheduled workday. <br />PART2- PRODUCTS <br />2.1 MATERIALS <br />A. The geomembrane shall be a polyethylene. The geomembrane shall be manufactured of new; first - <br />quality resin produced in the United States or Canada and shall be manufactured specifically for this <br />type of application. <br />B. The geomembrane sheet shall be comprised of a minimum ninety -six (96) percent pure polyethylene. <br />The remaining portion shall be made up of materials necessary for the performance of the liner (such as <br />carbon black, anti - oxidants, etc.) The geomembrane rolls shall meet the following SPECIFICATIONS: <br />The surface of the geomembrane shall not have striations, roughness (except texture as specified), <br />pinholes, or bubbles and shall be free of holes, blisters, undispersed raw materials, or any <br />contamination by foreign matter. MANAGER and CERTIFYING ENGINEER may request <br />additional testing in order to support such acceptance. All such testing shall be done at the sole <br />expense of the CONTRACTOR. <br />The geomembrane rolls shall have the following properties as indicated in Table 02776.1 -1 <br />Geomembrane August 28, 2013 <br />02776.1 -6 Revision 0 <br />S \Projects \1550 - CCRV Feld Spt CQA PSES BIdg�B 0 Project Engineering and Design \8 2 Specificahons\PSES Pipe Rack Liner Extension Specifications \02776 1 Geomembrane does <br />
