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 055000 Miscellaneous Metals-5 <br /> <br /> <br /> <br />E. Research/Evaluation Reports: For post-installed anchors, from ICC-ES. <br />1.6 QUALITY ASSURANCE <br /> <br />A. Welding Qualifications: Qualify procedures and personnel according to AWS D1.1/D1.1M, <br />"Structural Welding Code - Steel." <br /> <br />B. Welding Qualifications: Qualify procedures and personnel according to the following: <br /> <br />1. AWS D1.1/D1.1M, "Structural Welding Code - Steel." <br /> <br />2. AWS D1.2/D1.2M, "Structural Welding Code - Aluminum." <br /> <br />3. AWS D1.6/D1.6M, "Structural Welding Code - Stainless Steel." <br /> <br />1.7 FIELD CONDITIONS <br /> <br />A. Field Measurements: Verify actual locations of walls and other construction contiguous with <br />metal fabrications by field measurements before fabrication. <br />PART 2 - PRODUCTS <br /> <br />2.1 PERFORMANCE REQUIREMENTS <br /> <br />A. Delegated Design: Engage a qualified professional engineer, as defined in Section 014000 <br />"Quality Requirements," to design [ladders] [and] [alternating tread devices]. <br /> <br />B. Structural Performance of Aluminum Ladders: Aluminum ladders [, including landings,] <br />shall withstand the effects of loads and stresses within limits and under conditions specified <br />in ANSI A14.3. <br /> <br />C. Structural Performance of Alternating Tread Devices: Alternating tread devices shall <br />withstand the effects of gravity loads and the following loads and stresses within limits and <br />under conditions indicated. <br /> <br />1. Uniform Load: 100 lbf/sq. ft. (4.79 kN/sq. m). <br /> <br />2. Concentrated Load: 300 lbf (1.33 kN) applied on an area of 4 sq. in. (2580 sq. <br />mm). <br /> <br />3. Uniform and concentrated loads need not be assumed to act concurrently. <br /> <br />4. Alternating Tread Device Framing: Capable of withstanding stresses resulting from <br />railing loads in addition to loads specified above. <br /> <br />D. Thermal Movements: Allow for thermal movements from ambient and surface temperature <br />changes acting on exterior metal fabrications by preventing buckling, opening of joints, <br />overstressing of components, failure of connections, and other detrimental effects. <br />
