821.03 General. Each luminaire shall be installed according to the luminaire
manufacturer’s recommendations. Luminaires which are pole mounted shall be mounted on site such that poles and arms are not left unloaded. Pole mounted luminaires shall be leveled/adjusted after poles are set and vertically aligned before being energized. When mounted on a tenon, care shall be exercised to ensure maximum insertion of the mounting tenon. Each luminaire ballast and/or ballast arrangement shall be checked to ensure compatibility with the project power system. When the luminaire has a multi-tap ballast, the tap shall be adjusted as necessary to ensure a voltage match. When the night-time check of the lighting system by the Engineer indicates that any luminaires are misaligned, the misaligned luminaires shall be corrected at no additional cost. Should the photometric results of the luminaire indicate, in the judgment of the Engineer, a tilt adjustment is warranted, the adjustment shall be made at no additional cost. No luminaire shall be installed before it is approved. Where independent testing is required, full approval will not be given until complete test results, demonstrating compliance with the specifications, have been reviewed and accepted by the Engineer. Pole wiring shall be provided with the luminaire. Included with the pole wiring shall be a surge protection device and fusing located in the handhole. Wire shall be trained within the pole or sign structure so as to avoid abrasion or damage to the insulation. Pole wire shall be extended through the pole, pole grommet, luminaire ring, and any associated arm and tenon. The pole wire shall be terminated in a manner that Roadway Luminaires Art. 821.06 avoids sharp kinks, pinching, pressure on the insulation, or any other arrangement prone to damaging insulation value and producing poor megger test results. Wires shall be trained away from heat sources within the luminaire. Wires shall be terminated so all strands are extended to the full depth of the terminal lug with the insulation removed far enough so it abuts against the shoulder of the lug, but is not compressed as the lug is tightened. When installing the lamp or performing any other activity that requires opening of the optical assembly, care shall be exercised to avoid touching the reflector or allowing contaminants to enter the assembly. Each lamp and lens shall be free of all dirt, smudges, etc. Should the reflector or refractor require cleaning, a mild soap or non-abrasive detergent, containing no chlorinated or aromatic hydrocarbons, shall be used and then rinsed clean with cold water and wiped dry.
821.04 Conventional Pole Installation. Horizontal mount luminaires shall be
installed in a level, horizontal plane, with adjustments as needed to ensure the optics are set perpendicular to the traveled roadway. When the pole is bridge mounted, a minimum size stainless steel 1/4-20NC set screw shall be provided to secure the luminaire to the mast arm tenon. A hole shall be drilled and tapped through the tenon and luminaire mounting bracket and then fitted with the screw.
821.05 Highmast Installation. Luminaires having asymmetrical photometric
distributions shall be carefully oriented with respect to the roadway as indicated on the plans and as directed by the Engineer. The Contractor shall confirm all luminaire orientations with the Engineer prior to installation. For horizontal mounts having rotating optical assemblies, after the orientation of each mast arm tenon is inspected and approved by the Engineer, the position shall be permanently marked in a manner acceptable to the Engineer. The luminaire shall then be leveled to the plane of the luminaire ring. When the luminaire position and orientation has been confirmed and approved by the Engineer, the luminaire shall be anchored with a minimum size 1/4-20NC stainless steel bolt installed through tapped holes in the tenon and mounting bracket of the luminaire. The bolt shall not penetrate into the tenon more than 1/4 in. (6 mm). Counterweights on un-used tenons shall be mounted in a similar manner. Pre-installed wire on the tower ring shall have the ends of each wire capped at the tenon with butt type crimp-connectors for un-used tenons. The wires shall then be re-inserted into the tenon end and the tenon end shall be capped.
821.06 Underpass Installation. When attached directly to a structure, the
underpass luminaire shall have stainless steel brackets installed between the luminaire and the structure to create a gap of not less than 1 in. (25 mm). When specified, an aluminum underpass luminaire numbering decal bracket for each underpass luminaire shall be installed as shown on the plan. The bracket shall be large enough to accommodate the identification and shall be mounted on the pier or retaining wall from which the luminaires are electrically fed as directed by the Engineer. Art. 821.06 Roadway Luminaires When suspended, the underpass luminaire shall be installed 1 in. (25 mm) above the lowest underpass beam and shall be mounted parallel to the plane of the roadway, taking into consideration the applicable grade and superelevation of the traveled lanes. Vibration dampening assemblies shall be used and sized to the weight and shape of the underpass luminaire. All mounting hardware, including the vibration dampers, shall be stainless steel. The underpass luminaire shall include, from the junction box mounted at the abutment to the luminaire(s), all conduit, fittings, attachment hardware, cable, and stainless steel junction boxes required to complete the branch circuit.
821.07 Sign Lighting Installation. Each luminaire shall be mounted on the
sign walkway structure with stainless steel hardware and with at least three points of attachment. The mounted luminaire or mounting hardware shall not extend above the bottom of the sign or below the bottom of the walkway support. The center-to-center spacing of the luminaires will be determined by the Engineer. The end sections shall not exceed one-half the spacing between luminaires. The mounting shall provide the correct position of the luminaire as recommended by the manufacturer and shall be able to withstand assigned loading according to AASHTO. The sign lighting installation shall include, from the sign truss handhole to the luminaire, all aluminum conduit, fittings, attachment hardware, cable, and a stainless steel disconnect switch with lockable exterior handle mounted within reach from the walkway. Disabling brightness shall be shielded from traffic approaching either the front or back of the sign.
821.08 Basis of Payment. This work will be paid for at the contract unit price
per each for LUMINAIRE, of the lamp type, mount type, and wattage specified; UNDERPASS LUMINAIRE, of the wattage and lamp type specified; or SIGN LIGHTING, of the lamp type specified. SECTION 822. OBSTRUCTION WARNING LUMINAIRES
822.01 Description. This work shall consist of furnishing and installing light
emitting diode (LED) obstruction warning luminaires complete with all supports, hardware, wiring, and connections to the structure or pole, and appurtenant mounting accessories.
