2. The Rhinobond membrane attachment application is acceptable. Manufacturer must <br /> review the contract drawings and provide a tested system fastener pattern that meets or <br /> exceed the specified wind pressure requirements for the local codes. <br /> 3. The roofing membrane shall be unrolled and positioned with proper overlap. Minimum <br /> overlap shall be as specified by the manufacturer/supplier. Laps shall be shingled with the <br /> slope of the roof, where possible. Field seams shall be perpendicular or parallel to the <br /> direction of water flow, where possible. <br /> 4. The attachment method used shall conform to the recommendations of the SPRI <br /> manufacturer/supplier and approved shop drawings. <br /> 5. For the plate-bonded system, the membrane shall be heat welded to the polymer-coated <br /> plates used to secure the insulation boards using the recommended heat induction <br /> machines as prescribed by the manufacturer. <br /> B. Seaming: <br /> 1. The overlapping sheets shall be welded together using hot air as recommended by the <br /> manufacturer. <br /> 2. The welded seams shall be checked for continuity and integrity. Test cuts or coupons shall <br /> be taken, 1 per every 100 sq.ft. of membrane installed and each time the welding machine <br /> is turned off and on again. All imperfections or cold welds shall be stripped in as <br /> prescribed by the manufacturer. <br /> 3. The seam shall be completed by the application of a seam sealant daily, if required by the <br /> manufacturer. <br /> C. Membrane Termination/Securement: <br /> 1. Securement shall be provided at all membrane terminations at the perimeter of each roof <br /> level, roof section, curb flashing, skylight, expansion joint, interior wall, penthouse, and <br /> any other horizontal-to-vertical transitions. <br /> 2. Securement shall be provided at any angle change where the slope or combined slopes <br /> exceed(s)two inches in one horizontal foot. <br /> 3. Mechanical securement shall meet the pull-out strengths required by the SPRI Wind <br /> Design Guide or manufacturer's requirements, whichever is more stringent. <br /> 4. All membrane termination fasteners shall be sealed in accordance with the SPRI or <br /> manufacturer's requirements, whichever is more stringent. <br /> 5. Air Seal: The membrane is to be sealed and mechanically secured at 6" o.c. at all <br /> perimeters at the elevation where the bay doors are positioned. Apply sealing SA <br /> membrane at all penetrations within the Zone 3 and Zone 2 area over the bay door <br /> elevation. <br /> 6. Lay out membrane with 2" minimum overlap and allow it to relax. Clean the lap splice area <br /> and prime the surfaces (if required) as prescribed by the manufacturer. Join the sheets of <br /> membrane using hot air weld with a hot air robotic automatic welder as prescribed by the <br /> manufacturer. At end laps and "T"joints, provide cover strips as required. <br /> D. Yellow Safety Warning Line: <br /> 1. Install 10'from roof perimeter edge where parapet walls are less than 42" tall. <br /> 3.07 FLASHINGS: <br /> A. General: <br /> 1. Contractor shall complete all flashings at roof terminations, curbs, and penetrations in <br /> accordance with manufacturer's approved details and in compliance with the drawings. <br /> B. Base flashings: <br /> 1. The membrane is to be sealed and secured at all perimeters at the elevation where the <br /> bay doors are positioned with an approved SA membrane. Apply sealing SA membrane at <br /> all penetrations within the Zone 3 and Zone 2 area over the bay door elevation. <br /> 2. Under no conditions shall the new membrane flashing cover weep holes or any form of <br /> through wall drainage. <br /> SEA00511 / Prologis - SEA00511 07 5400 - 10 THERMOPLASTIC MEMBRANE <br /> - FY24- Everett 1 - Capital ROOF SYSTEM <br /> Roofing Project <br />
