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 051400-5 <br /> <br /> <br />D. Where structural joints are welded, the detail of the joints, welding technique, weld <br />quality and appearance, and methods for correcting defective welds shall conform to the <br />AWS D1.2. <br />1. Welding Process: Inert shielded gas or resistance welding process. <br /> <br />E. Where milling is indicated on the Drawings, machine the contact surfaces true to obtain <br />full and complete contact. <br /> <br />F. Structural members are selected from generally available rolled sections; however, if the <br />specified sections are not available, provide sections with equivalent physical properties <br />at no additional cost after approval by the University. <br /> <br />2.4 FINISHES <br /> <br />A. Where aluminum will contact dissimilar metals, protect against galvanic action by <br />painting contact surfaces as follows: <br /> <br />1. Where aluminum members are in contact with steel, prime both aluminum and <br />steel members with one coat of paint meeting Federal Specification TT-P-645. <br />Paint t aluminum with an additional coat of varnish containing [2 pounds] [1 kg] <br />of aluminum pigment per [gallon] [3.8 liters]. <br /> <br />2. Where aluminum members are in contact with porous materials, masonry or <br />concrete, apply to the contact surfaces of the aluminum members a heavy coat <br />of alkali resistant bituminous paint. <br /> <br />3. Where aluminum members are embedded in concrete containing admixtures <br />which are corrosive to aluminum, or in concrete subjected to highly corrosive <br />environments, prime the aluminum with one coat of paint meeting Federal <br />Specification TT-P-645. Otherwise, aluminum members embedded in concrete <br />need not be painted. <br /> <br />PART 3 - EXECUTION <br /> <br />3.1 PREPARATION <br /> <br />A. Provide temporary supports and internal braces necessary to support structure during <br />erection. Temporary supports and braces shall be adequate for anticipated wind, <br />seismic, equipment and erection loads. Remove temporary shoring after the erection is <br />complete. <br /> <br />B. Before erection, paint contact surfaces between dissimilar materials. <br /> <br />3.2 EXAMINATION <br /> <br />A. Verify that field conditions are acceptable and are ready for erection. <br /> <br />B. Beginning of installation means Subcontractor accepts that existing conditions meet the <br />requirements for installation. <br />
