THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 055200 Metal Railing-6 <br /> <br /> <br />F. Formed work: Form metal work to the required dimensions, shapes and sizes, with true <br />curves, lines and angles. Provide necessary rebates, lugs, flanges, covers and brackets for <br />assembly of units. Use concealed fasteners wherever possible. <br /> <br />G. Welding: Comply with AWS for recommended practices in shop welding. Provide welds <br />behind finished surfaces without distortion or discoloration of the exposed side. Clean <br />exposed welded joints. <br /> <br />1. Unless specified, detailed, or approved otherwise on shop drawings, weld all shop <br />connections and all field connections. <br /> <br />2. Unless otherwise approved, grind exposed welds smooth and flush to match and <br />blend with adjoining surfaces. <br /> <br />H. Fit-up: Mill joints to a tight, hairline fit. Cope or miter corner joints. <br /> <br />I. Castings: Provide castings that are sound and free of warp or defects which impair strength <br />and appearance. Finish exposed surfaces to smooth, sharp, well-defined lines and arises. <br /> <br />J. Anchorage: Provide brackets and anchors for joining and securing rails. Furnish inserts <br />and sleeves as required for anchorage to concrete, and structural supports. <br /> <br /> 3.3 INSTALLATION <br /> <br />A. Install manufactured items in accord with manufacturer’s instructions and approved shop <br />drawings. <br /> <br />B. Set all work accurately to lines and levels, plumb and secure. <br /> <br />C. Install members, bolts, anchors, and inserts to be covered, inserted or built-in, as the work <br />progresses. <br /> <br />D. Perform all cutting, drilling and fitting required for the installation of work specified. <br /> <br />E. Where cutting, welding and grinding are required for proper fitting and jointing of the work, <br />restore finishes to match original shop applied finish. <br /> <br />F. Set posts in 2" diameter drilled holes not less than 3" deep, but not more than 4" deep. <br />Clean holes of loose material and fill with anchoring cement flush with the surface of the <br />slab. Do not leave a recess where water may collect. <br /> <br />G. Fit work to existing structural supports with close uniform joints. Secure rigidly, without <br />movement, level and plumb. Top rail shall present a straight level appearance, without <br />waves in any direction. <br /> <br />H. Where field welding is required and approved, conform to requirements of AWS. <br /> <br />I. Corrosion Protection: Coat concealed surfaces of aluminum, which will be in contact with <br />grout, concrete, masonry, wood, or dissimilar metals, with a heavy coat of bituminous paint <br />or zinc chromate primer.
