When polishing is completed, passivate and rinse surfaces. Remove embedded foreign matter and leave <br />surfaces chemically clean. <br />PART 3 - EXECUTION <br />3.1 EXAMINATION <br />3.2 INSTALLATION, GENERAL <br />A. Fit exposed connections together to form tight, hairline joints. <br />B. Perform cutting, drilling, and fitting required for installing railings. Set railings accurately in location, <br />alignment, and elevation; measured from established lines and levels and free of rack. <br />1. Do not weld, cut, or abrade surfaces of railing components that have been coated or finished after <br />fabrication and that are intended for field connection by mechanical or other means without further <br />cutting or fitting. <br />2. Set posts plumb within a tolerance of 1/16 inch in 3 feet (2 mm in 1 m). <br />3. Align rails so variations from level for horizontal members and variations from parallel with rake <br />of steps and ramps for sloping members do not exceed 1/4 inch in 12 feet (5 mm in 3 m). <br />C. Corrosion Protection: Coat concealed surfaces of aluminum that will be in contact with grout, concrete, <br />masonry, wood, or dissimilar metals, with a heavy coat of bituminous paint. <br />D. Adjust railings before anchoring to ensure matching alignment at abutting joints. <br />E. Fastening to In -Place Construction: Use anchorage devices and fasteners where necessary for securing <br />railings and for properly transferring loads to in-place construction. <br />3.3 RAILING CONNECTIONS <br />A. Welded Connections: Use fully welded joints for permanently connecting railing components. Comply <br />with requirements for welded connections in "Fabrication" Article whether welding is performed in the <br />shop or in the field. <br />B. Expansion Joints: Install expansion joints at locations indicated but not farther apart than required to <br />accommodate thermal movement. Provide slip joint internal sleeve extending 2 inches (50 nun) beyond <br />joint on either side, fasten internal sleeve securely to one side, and locate joint within 6 inches (150 mm) <br />of post. <br />y <br />Wabasso Beach Park 05521-6 <br />Indian River County <br />DAA Project No. 6008 <br />
