  3. Related Sections include the following:
  4. Division16 Section "Exterior Lighting" for lighting fixtures, lamps, ballasts, and accessories.

1.2DEFINITIONS

  1. Luminaire: Complete lighting fixture, including ballast housing if provided.
  2. Pole: Luminaire support structure, standard excluding foundation used to illuminate large area.
  3. Standard: Same definition as "Pole" above.

1.3PERFORMANCE REQUIREMENTS

  1. Dead Load: Weight of luminaire and its horizontal and vertical supports, lowering devices, and supporting structure, applied as stated in AASHTOLTS-3.
  2. Ice Load: Load of 3 lbf/sq. ft., applied as stated in AASHTOLTS-3.
  3. Wind Load: Pressure of wind on standard and luminaire, calculated and applied as stated in AASHTOLTS-3.
  4. Wind speed for calculating wind load for poles 50 feet in height or less is 110 mph.

1.4SUBMITTALS

  1. Product Data: For each type of pole indicated, arranged in order of lighting unit designation. Include data on accessories, finishes, and the following:
  2. Materials and dimensions of poles.
  3. Means of attaching luminaires and indication that attachment is suitable for it.
  4. Bases.
  5. Shop Drawings: Include anchor-bolt templates keyed to specific poles and certified by manufacturer.
  6. Design calculations, certified by a qualified professional engineer, indicating strength of screw foundation.
  7. Product Certificates: Signed by manufacturer of poles, certifying that products are designed for load requirements in AASHTOLTS-3 and that load imposed by luminaire has been included in design.

1.5DELIVERY, STORAGE, AND HANDLING

  1. Package aluminum poles for shipping according to ASTMB660.
  2. Store poles on decay-resistant-treated skids at least 12 inches above grade and vegetation. Support poles to prevent distortion and arrange to provide free air circulation.
  3. Retain factory-applied pole wrappings on metal poles until just before pole installation. For poles with nonmetallic finishes, handle with web fabric straps.

1.6WARRANTY

  1. Special Warranty: Manufacturer's standard form in which manufacturer agrees to repair or replace lighting poles and standards that fail in finish, materials, and workmanship within specified warranty period.
  2. Protection of Metal from Corrosion: Warranty against perforation or erosion of finish due to weathering.
  3. Color Retention: Warranty against fading, staining, and chalking due to effects of weather and solar radiation.
  4. Warranty Period: Manufacturer's standard, but not less than three years from date of Substantial Completion.

PART 2 - PRODUCTS

2.1MANUFACTURERS

  1. Manufacturers: Subject to compliance with requirements, provide products by one of the following:
  2. Holophane Corporation.
  3. Hubbell Lighting, Inc.
  4. Lithonia Lighting.
  5. Millerbernd Manufacturing Company.
  6. Union Metal Corp.
  7. Valmont Industries, Inc.

2.2POLES, GENERAL

  1. Description: Comply with AASHTOLTS-3 in structural design of poles.
  2. Wind-Load Strength of Poles: Adequate at indicated heights above grade without failure, permanent deflection, or whipping in steady winds of speed indicated in "Performance Requirements" Article, with a gust factor of 1.3.
  3. Strength Analysis: For each pole, multiply the actual equivalent projected area of luminaires and brackets by a factor of 1.25 to obtain the equivalent projected area to be used in pole selection strength analysis.
  4. Luminaire Attachment: Structural supports to comply with luminaire mounting requirements.
  5. Finish: Match finish of pole and support structure on arm, bracket, and tenon mount materials.
  6. Mountings, Fasteners, and Appurtenances: Corrosion-resistant items compatible with support components.
  7. Materials: Shall not cause galvanic action at contact points.
  8. Mountings: Correctly furnish to position luminaire attachment to provide indicated light distribution.
  9. Anchor Bolts, Leveling Nuts, Bolt Caps, and Washers: Hot-dip galvanized after fabrication unless stainless-steel items are indicated.
  10. Anchor-Bolt Template: Steel.

2.3ALUMINUM POLES

  1. Poles: Seamless, extruded structural tube complying with ASTMB429, 6063-T6 alloy with access handhole in pole wall.
  2. Poles: ASTMB209, 5052-H34 marine sheet alloy with access handhole in pole wall.
  3. Shape: Square, straight.
  4. Grounding and Bonding Lugs: Welded 1/2-inch threaded lug, complying with requirements in Division16 Section "Grounding and Bonding," listed for attaching grounding and bonding conductors of type and size listed in that Section, and accessible through handhole.
  5. Brackets for Luminaires: Detachable, with pole and adapter fittings of cast aluminum. Adapter fitting welded to pole and bracket, and then bolted together with stainless-steel bolts.
  6. ClassI, Color Anodic Finish: AA-M32C22A42/A44 (Mechanical Finish: medium satin; Chemical Finish: etched, medium matte; Anodic Coating: Architectural ClassI, integrally colored or electrolytically deposited color coating 0.018 mm or thicker) complying with AAMA611.
  7. Color: Dark bronze.

2.4ACCESSORIES

  1. Cast base cover, of same material and color as pole.

PART 3 - EXECUTION

3.1ERECTION, GENERAL

  1. Set reinforcement for anchor bolts, nuts, and washers according to anchor-bolt templates furnished by pole manufacturer. Refer to drawings for concrete foundation details.
  2. Concrete Finish: For exposed finish, comply with Division 3.
  3. Install poles as follows:
  4. Use web fabric slings (not chain or cable) to raise and set poles.
  5. Mount pole to foundation with leveling nuts, and tighten top nuts to torque level recommended by pole manufacturer.
  6. Secure poles level, plumb, and square.
  7. Grout void between pole base and foundation. Use nonshrink or expanding concrete grout firmly packed to fill space.
  8. Use a short piece of 1/2-inch diameter pipe to make a drain hole through grout. Arrange to drain condensation from interior of pole.

3.2CORROSION PREVENTION

  1. Aluminum: Do not use in contact with earth or concrete. When in direct contact with a dissimilar metal, protect aluminum by insulating fittings or treatment.
  2. Steel Conduits: Comply with Division16 Section "Raceways and Boxes." In concrete foundations, wrap conduit with 0.010-inch thick, pipe-wrapping plastic tape applied with a 50 percent overlap.

3.3GROUNDING

  1. Ground metal poles/support structures according to Division16 Section "Grounding."
  2. Install grounding electrode for each pole.
  3. Install grounding conductor pigtail in the base for connecting luminaire to grounding system and make all final connections.
