Buffalo Wild Wings

Buffalo Wild WingsD. Roof Walkway Pads: Install pads in accordance with roofing manufacturer's instructions.1. Prepare dirty or weathered membrane:a. Remove any visible dirt and debris with a clean rag and water.b. For heavily contaminated surface, scrubbing with a detergent cleaner (i.e. Fantastik or409) followed by a water rinse may be necessary.2. Install roof walkway pads forming a direct path, in lines parallel to the building faces, fromthe roof access hatch to each piece of rooftop mechanical equipment.3. Position walkway pad and cut to desired length.4. Whenever possible, do not cover membrane seams with walkway pad. When installedadjacent to a seam, keep the pad a minimum of 2 inches from the edge of the seam on thebottom sheet of the completed lap and a minimum of 6 inches from the edge of the seamwhen located on the top sheet of a completed lap.5. When covering seams is unavoidable, the lap seam should be completed in accordancewith manufacturer's specifications and thoroughly probed with any deficiencies repairedprior to pad installation.6. In circumstances where drainage around the walkway pad is a concern, shorter walkwaypad lengths spaced with a 2 inch gap may be desired.7. Weld perimeter of walkway pad to the membrane following standard welding procedures.Periodic breaks in the weld of 1 to 2 inches are required on the low slope edge of the padto prevent the accumulation of water under the pad.3.10 FIELD QUALITY CONTROLA. Ensure that metal work shall be secured in a manner approved by roofing manufacturer, or inaccordance with SMACNA guidelines, to prevent damage from buckling, or wind exposure. Allmetal work that is part of the waterproofing envelope shall be sealed, structurally sound, andappropriately anchored to prevent leakage.B. Tests:1. Seam Tests: Probe the entire lap edge of each seam with an approved seam probing tool(Sears cotter-pin extractor) after seam has cooled completely to verify seam consistency.Probing before the seam area has cooled will damage the membrane.2. Destructive Seam Tests: Test 3 inch wide area of seam weld to verify good peel strength.A properly welded seam will have membrane delamination from scrim prior to weld failure.Perform the following destructive tests on welds:a. First seam of each working day.b. First seam after the automatic hot-air welder has been allowed to cool down.c. After any extreme changes in weather conditions.C. Manufacturer's Field Service: Upon completion of the installation, the manufacturer'srepresentative shall make an inspection to ascertain that the roofing membrane system hasbeen installed according to manufacturer's approved specifications and details.D. Warranty Inspection: Provide manufacturer's inspection for acceptance for warranty.E. Rejection of Defective Work: Areas having excessive patching as a result of damage to themembrane or faulty installation may be rejected by membrane manufacturer or the Architect;replace the membrane completely in these areas.END OF SECTION04-27-11 MECHANICALLY ATTACHED MEMBRANE ROOFING07535 -5
