C. Fasteners for Interconnecting Railing Components: <br />1. Provide concealed fasteners for interconnecting railing components and for attaching them to other <br />work, unless exposed fasteners are unavoidable. <br />2. Provide tamper-resistant flat -head machine screws for exposed fasteners unless otherwise <br />indicated. <br />D. Post -Installed Anchors: Torque -controlled expansion anchors or chemical anchors capable of sustaining, <br />without failure, a load equal to six times the load imposed when installed in unit masonry and four times <br />the load imposed when installed in concrete, as determined by testing according to ASTM E 488, <br />conducted by a qualified independent testing agency. <br />1. Material for Exterior Locations and Where Stainless Steel is Indicated: Alloy Group 2 (A4) <br />stainless-steel bolts, ASTM F 593 (ASTM F 738M), and nuts, ASTM F 594 (ASTM F 836M). <br />2.5 MISCELLANEOUS MATERIALS <br />A. Welding Rods and Bare Electrodes: Select according to AWS specifications for metal alloy welded. <br />1. For stainless-steel railings, provide type and alloy as recommended by producer of metal to be <br />welded and as required for color match, strength, and compatibility in fabricated items. <br />B. Bituminous Paint: Cold -applied asphalt emulsion complying with ASTM D 1187, <br />C. Nonshrink, Nonmetallic Grout: Factory -packaged, nonstaining, noncorrosive, nongaseous grout <br />complying with ASTM C 1107. Provide grout specifically recommended by manufacturer for interior <br />and exterior applications. <br />D. Anchoring Cement: Factory -packaged, nonshrink, nonstaining, hydraulic -controlled expansion cement <br />formulation for mixing with water at Project site to create pourable anchoring, patching, and grouting <br />compound. <br />1. Water -Resistant Product: At exterior locations provide formulation that is resistant to erosion <br />from water exposure without needing protection by a sealer or waterproof coating and that is <br />recommended by manufacturer for exterior use. <br />2.6 FABRICATION <br />A. General: Fabricate railings to comply with requirements indicated for design, dimensions, member sizes <br />and spacing, details, finish, and anchorage, but not less than that required to support structural loads. <br />B. Assemble railings in the shop to greatest extent possible to minimize field splicing and assembly. <br />Disassemble units only as necessary for shipping and handling limitations. Clearly mark units for <br />reassembly and coordinated installation. Use connections that maintain structural value of joined pieces. <br />C. Cut, drill, and punch metals cleanly and accurately. Remove burrs and ease edges to a radius of <br />approximately 1/32 inch (1 mm) unless otherwise indicated. Remove sharp or rough areas on exposed <br />surfaces. <br />Wabasso Beach Park 05521-4 <br />Indian River County <br />DAA Project No. 6008 <br />
