Item Article/Section
a.Light Poles ........................................................................... 1069.01-1069.05
b.Mounting Pad .................................................................................... 1069.07
c.Pole/Unit Identification ....................................................................... 1069.06 CONSTRUCTION REQUIREMENTS Art. 830.03 Light Poles
830.03 Installation. The light pole shall be set plumb on the foundation
without the use of shims, or washers for leveling. On bridge parapet walls, a vibration mounting pad shall be installed between the foundation leveling plate and the light pole. The handhole shall be located such that workers accessing the handhole shall face oncoming traffic directly or located on the back side of the pole facing the roadway. On bridge parapet walls, the access handhole shall be oriented facing the roadway. On center median barrier walls, all access handholes shall be oriented to the one side with the least traffic flow. Arms shall be set at right angles to the centerline of the pavement. Poles shall not be left in place without arm(s) and luminaire(s). The Contractor shall be responsible for furnishing pole mounting equipment that is of adequate strength and compatible for the pole it supports. This shall include, but not be limited to, the foundation, breakaway device (when specified), anchor rods, and hardware. Lighting unit identification numbers shall be installed before the lighting unit is energized.
a.Foundation Mounted Poles. The Contractor shall avoid contact of dissimilar metals in erecting the pole on its foundation and/or breakaway device. Any concern of trapped moisture or potential corrosion cell shall be resolved to the satisfaction of the Engineer.
b.Direct Embed Fiberglass Pole. The depth of a direct embed fiberglass pole in the ground shall not be less than ten percent of the pole length plus 2 ft (600 mm) with a minimum of 6 ft (1.8 m). Direct embed poles shall be raked 1 ft (300 mm). Care shall be taken to get the shear plane of the pole at groundline for breakaway poles. Backfill shall be tamped and compacted around the pole in 6 in. (150 mm) lifts.
c.Wood Pole. Poles shall be stored and handled according to ANSI O5.1. The depth of the pole in the ground shall not be less than ten percent of the pole length plus 2 ft (600 mm) with a minimum of 6 ft (1.8 m). The poles shall be raked 1 ft (300 mm). Backfill shall be tamped and compacted around the pole in 6 in. (150 mm) lifts. Pole guying shall be provided where indicated on the plans, at every dead end pole, and at any pole having non-offsetting cable support stresses.
830.04 Temporary Installation. Wood poles used for a temporary lighting
installation may be previously used poles as approved by the Engineer. The poles shall be in good condition and shall be according to the applicable ANSI requirements for sweep, crook, defects, and mechanical damage. Poles deemed unacceptable by the Engineer shall be removed from the jobsite.
