INDIAN RIVER COUNTY — NORTH COUNTY REGIONAL PARK PAGE 3 <br />AQUATIC FACILITY ROOFING REPLACEMENT SECTION 075216 <br />JUNE 7, 2019 MODIFIED BITUMINOUS MEMBRANE ROOFING <br />C. Evidence of Factory Mutual testing. <br />D. Evidence of Underwriters' Laboratories Class A acceptance of the proposed roofing <br />system. <br />E. Evidence and description of manufacturers' quality control/quality assurance program for <br />the primary roofing products supplied. The quality assurance program description shall <br />include all methods of testing for physical and mechanical property values. <br />F. Evidence the roof system has passed 500 cycles of ASTM D 5849 Resistance to Cyclic <br />Joint Displacement (fatigue) at WF (-100C). Passing results shall show no signs of <br />membrane cracking or interply delamination after 500 cycles. <br />G. Evidence the roof system has passed 200 cycles of ASTM D 5849 after heat conditioning <br />performed in accordance with ASTM D 5147. <br />H. Letter from the roofing manufacturer confirming that the membrane manufacturer has <br />been producing SBS products in the United States for a minimum of 10 years without a <br />change in the basic product design or SBS modified blend, e.g. no substantive changes <br />to the product composition, polymer specification, asphalt and filler formulation. <br />1. Letter from the proposed primary roofing manufacturer confirming the number of years it <br />has directly manufactured the proposed Nprimary roofing system under the trade name <br />and/or trademarks as proposed. <br />J. Letter from the proposed primary roofing manufacturer confirming that a phased roof <br />application, with only the modified bitumen base ply in place for a period of up to 10 <br />weeks is acceptable and approved for this project. <br />K. Letter from the proposed primary roofing manufacturer confirming that the filler content in <br />the elastomeric blend of the proposed roof membrane and flashing components does not <br />exceed 35% in weight. <br />L. Letter from the proposed primary roofing manufacturer confirming that the proposed roof <br />membrane and flashing components meet or exceed the physical and mechanical <br />requirements listed in Part 2 of this specification. <br />M. Letter from the proposed primary roofing manufacturer confirming that a Certificate of <br />Analysis confirming the physical and mechanical properties of the roofing membrane <br />components will be provided, for each production run of products, at the conclusion of the <br />project. <br />
