PART 3-EXECUTION <br /> 3.1 EXAMINATION <br /> A. Examine substrates, areas, and conditions,with Installer present, for compliance with <br /> requirements for installation tolerances,metal roof panel supports, and other conditions <br /> affecting performance of the Work. <br /> B. Examine primary and secondary roof framing to verify that rafters,purlins, angles, <br /> channels, and other structural panel support members and anchorages have been <br /> installed within alignment tolerances required by metal roof panel manufacturer. <br /> C. Examine solid roof sheathing to verify that sheathing joints are supported by framing or <br /> blocking and that installation is within flatness tolerances required by metal roof panel <br /> manufacturer. <br /> D. Examine roughing-in for components and systems penetrating metal roof panels to <br /> verify actual locations of penetrations relative to seam locations of metal roof panels <br /> before metal roof panel installation. <br /> E. For the record,prepare written report, endorsed by Installer, listing conditions <br /> detrimental to performance of the Work. <br /> F. Proceed with installation only after unsatisfactory conditions have been corrected. <br /> 3.2 PREPARATION <br /> A. Clean substrates of substances harmful to insulation, including removing projections <br /> capable of interfering with insulation attachment. <br /> 3.3 ROOF INSULATION INSTALLATION <br /> A. Comply with roofmg manufacturer's written instructions for installing roof insulation. <br /> B. Install insulation with long joints of insulation in a continuous straight line with end <br /> joints staggered between rows, abutting edges and ends between boards. Fill gaps <br /> exceeding 1/4 inch(6 mm)with insulation. <br /> 1. Cut and fit insulation within 1/4 inch (6 mm) of projections, and penetrations. <br /> C. Mechanically Fastened Insulation: Install each layer of insulation and secure to deck <br /> using mechanical fasteners specifically designed and sized for fastening specified <br /> board-type roof insulation to deck type. <br /> 1. Fasten insulation to resist uplift pressure at corners,perimeter, and field of roof. <br /> SEWER LIFT'STATION NO.24 REPLACEMENT PROJECT,UP 3313 <br /> Division 7 Thermal and Moisture Protection Page 07411-10 April 2012 <br />
