0 <br />3.5 <br />1. Install clips to substrate with self -tapping fasteners. <br />2. Install pressure plates at locations indicated in equipment manufacturer's written installation <br />instructions. <br />3. Before panels are joined, apply continuous bead of sealant to top of flange of lower panel. <br />4. Snap-On Seam: Nest standing seams and fasten together by interlocking and completely engaging <br />field -applied sealant. <br />5. Seamed Joint: Crimp standing seams with manufacturer -approved motorized seamer tool so cleat, <br />sheet metal roofing, and field -applied sealant are completely engaged. <br />C. Seal joints as shown and as required for watertight construction. For roofing with 3:12 slopes or less, use <br />cleats at transverse seams. <br />1. Where sealant -filled joints are used, embed hooked flanges of joint members not less than 1 inch <br />(25 mm) into sealant. Form joints to completely conceal sealant. When ambient temperature at <br />time of installation is moderate, between 40 and 70 deg F (4 and 21 deg C), set joint members for <br />50 percent movement either way. Adjust setting proportionately for installation at higher ambient <br />temperatures. Do not install sealant -type joints at temperatures below 40 deg F (4 deg Q. <br />2. Prepare joints and apply sealants to comply with requirements in Division 7 Section "Joint <br />Sealants." <br />ACCESSORY INSTALLATION <br />A. General: Install accessories with positive anchorage to building and weathertight mounting and provide <br />for thermal expansion. Coordinate installation with flashings and other components. <br />1. Install components required for a complete sheet metal roofing assembly including trim, copings, <br />seam covers, flashings, sealants, gaskets, fillers, metal closures, closure strips, and similar items. <br />2. Install accessories integral to sheet metal roofing that are specified in Division 7 Section "Sheet <br />Metal Flashing and Trim" to comply with that Section's requirements. <br />B. Flashing and Trim: Comply with performance requirements, manufacturer's written installation <br />instructions, and SMACNA's "Architectural Sheet Metal Manual." Provide concealed fasteners where <br />possible, and set units true to line and level as indicated. Install work with laps, joints, and seams that <br />will be permanently watertight and weather resistant. <br />1. Install flashing and trim as required to seal against weather and to provide finished appearance. <br />Locations include, but are not limited to, eaves, rakes, corners, bases, framed openings, ridges, <br />fasciae, and fillers. <br />2. Install continuous strip of self -adhering underlayment at edge of continuous flashing overlapping <br />self -adhering underlayment, where "continuous seal strip" is indicated in SMACNA's <br />"Architectural Sheet Metal Manual," and where indicated on Drawings. <br />3. Install exposed flashing and trim without excessive oil canning, buckling, and tool marks and true <br />to line and levels indicated, with exposed edges folded back to form hems. Install sheet metal <br />flashing and trim to fit substrates and to result in waterproof and weather -resistant performance. <br />4. Expansion Provisions: Provide for thermal expansion of exposed flashing and trim Space <br />movement joints at a maximum of 10 feet (3 m) with no joints allowed within 24 inches (600 mm) <br />of comer or intersection. Where lapped expansion provisions cannot be used or would not be <br />sufficiently weather resistant and waterproof, form expansion joints of intermeshing hooked <br />flanges, not less than 1 inch (25 mm) deep, and filled with butyl sealant concealed within joints. <br />Wabasso Beach Park <br />Indian River County <br />DAA Project No. 6008 <br />07610-9 <br />
