SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br />EXTERIOR LIGHTING 16521 - 4 <br />1. Metal-Halide Color Temperature and Minimum Color-Rendering Index: 3600 K and <br />70 CRI, unless otherwise indicated. <br />2.3 <br />A. Description: Comply with AASHTO LTS-3 for pole or other support structures, brackets, <br />arms, appurtenances, base, and anchorage and foundation. <br />LUMINAIRE SUPPORT COMPONENTS <br />B. Wind-Load Strength of Total Support Assembly: Adequate to carry support assembly plus lu- <br />minaires at indicated heights above grade without failure, permanent deflection, or whipping in <br />steady winds of 100 mph (192 km/h) with a gust factor of 1.3. Support assembly includes pole <br />or other support structures, brackets, arms, appurtenances, base, and anchorage and foundation. <br />1. Strength Analysis: For each pole type and luminaire combination, multiply the actual <br />equivalent projected area of luminaires and brackets by a factor of 1.1 to obtain the <br />equivalent projected area to be used in pole selection strength analysis. <br />C. Finish: Match finish of pole/support structure for arm, bracket, and tenon mount mate- <br />rials. <br />D. Mountings, Fasteners, and Appurtenances: Corrosion-resistant items compatible with support <br />components. <br />E. Pole and Support Structure Bases: Shall be as specified and detailed on the electrical drawings. <br />PART 3 - EXECUTION <br />3.1 <br />A. Concrete Foundations: Construct according to Division 3 Section "Cast-in-Place Concrete." <br />INSTALLATION <br />1. Comply with details for reinforcement and for anchor bolts, nuts, and washers. Verify <br />anchor-bolt templates by comparing with actual pole bases furnished. <br />2. Finish for Parts Exposed to View: Trowel and rub smooth. Comply with Division 3 Sec- <br />tion "Cast-in-Place Concrete" for exposed finish. <br />B. Embedded Poles: Set poles to indicated depth, but not less than one-sixth of pole length <br />below finish grade. Dig holes large enough to permit use of tampers the full depth of <br />hole. Backfill in 6-inch (150-mm) layers and thoroughly tamp each layer so compaction <br />of backfill is equal to or greater than that of undisturbed earth. <br />C. Install poles as follows: <br />1. Use web fabric slings (not chain or cable) to raise and set poles. <br />2. Mount pole to foundation with leveling nuts, and tighten top nuts to torque level recom- <br />mended by pole manufacturer. <br />3. Secure poles level, plumb, and square. <br />4. Grout void between pole base and foundation. Use nonshrinking or expanding concrete <br />grout firmly packed in entire void space.
