635.01 Description . This work consists of furnishing traffic signal heads of the type
specified in the plans and installing them in accordance with these specifications and the details shown in the plans or as directed.
635.02 Materials . Materials furnished for traffic signal head installation shall conform
to the requirements of Subsection 722.14.
635.03 Construction Requirements .
635.03.1 Construction Details . Traffic signal heads shall be mounted on the messenger
cable, mast arms, or pedestal poles and conn ected to the signal supply cable as indicated on the plans and as required in these specifications. Initial location and alignment of signal heads shall be performed as indicated on plans. Final positioning and aligning shall be performed by field observation to obtain optimum visibility of the signal f aces by approach traffic. Ample slack shall be left in the signal supply cable to provide for field adjustment of head alignment and to form drip loops after heads are in final position. Traffic signal heads not in use shall be adequately covered by the Contractor to the satisfaction of the Engineer. The signal heads shall be covered with a durable, outdoor- hardened material designed for the specific si gnal head configuration. The color of this covering shall contrast with the color of the signal head. The covering material shall be approved by the Engineer and clearly designate to drivers that the covered signal heads are not in stop and go mode.
635.04 Me thod of Measurement. Traffic signal heads of the types specified will be
measured as a unit quantity per each. 635.05--Basis of Payment. Traffic signal heads of the types specified, measured as prescribed above, will be paid for at the cont ract unit price per each, which price shall be full compensation for furnishing housing, mounting attachments, lens, lamps, reflectors, visors, sockets, socket wiring, back plates wh ere specified, turn-signal signs, tether cable, and all other materials; for installing, mounting, connecting, aligning, testing, and for all equipment, labor, tools, and incidentals necessary to complete the work. Payment will be made under: 635-A: Traffic Signal Head, Type ___ - per each SECTION 636 - ELECTRICAL CABLE
636.01 Description. This work consists of furnishing new or removal of existing cable(s),
erecting, installing and/or relaying electric cable “mains” in conformity with these specifications and true to locations, line and grades as shown on the plans or as directed. It shall include excavating, laying or relaying of cable(s), placing tracer cable or tape, backfilling, replacing sod, aeri al supports and/or pull-through conduits as applicable.
636.02 Materials. The materials used in this construction shall be of the type and size
indicated on the plans and shall conform to the applicable requirements of Subsection 722.03.
636.03 Construction Requirements. Except where indicated on the plans or approved
by the Engineer, cables shall be spliced with a water proof enclosure only in pole bases, pull boxes or controller cabinets. At each splice, sufficient slack shall be left in the cable for re-splicing. The greatest care shall be ex ercised in handling all cable to avoid damage to the conductor and its coverings. No sharp bends shall be permitted to form; reels shall not be dropped; and cable with discernable damage in any part shall be rejected. All connections shall be made with approved terminal blocks meeting the applicable requirements of Subsection 722.08.
636.03.1 Direct Buried Cable. Trenches shall be excavated by hand or mechanical
methods to the depth and width indicated on the plans, or as directed. The cable shall be laid on a six (6)-inch cushion as shown on the plans or as directed and covered with a similar layer. A minimum cover of 24-inches total is required. The electric cable shall be "snaked" laid in the trench. The earth backfill then shall be placed in layers of eight inches (8”) or less, and each layers compacted by approved methods to the density of adjacent ground. Cable placed under traveled roadways shall be pulled through previously placed conduit, and such pulling shall be incidental to work.
