SECTION 686 - RELOCATION OF EXISTING LIGHTING ASSEMBLIES
686.01 Description. In additional to the requirements set forth in Section 681, relocation
of existing lighting assemblies of the types indicated on the plans shall consist of removing and relocating pole, luminaire, providing new foundation and miscellaneous hardware. Wiring shall be reworked or replaced as directed below and on the plans.
686.02 Materials. Generally, all the materials needed to relocate the lighting
assembly(ies) will be existing materials. Th e lighting assemblies, wire and foundations may be either permanent or temporary. Wiring, ground rods, bolts and other items shall be relocated as per the plans. Additional items necessary for a complete working lighting assembly shall be required whether or not mentioned in these specifications.
686.02.1 Poles. Steel poles are hot-rolled weldable grade steel, galvanized in accordance
with ASTM A 123, length as indicated on the plans. Since the anchor bolt layout may vary from pole to pole, the Contractor shall field verify bolt circles of existing lighting assemblies. Timber poles, used on temporary lighting sy stems, shall conform to the applicable requirements of Section 685. Voids left by the removal of these poles shall be filled and compacted as directed by the Engineer.
686.02.2 Luminaire. Low mast luminaires are bracket arm mounted type, 250 or 400-
watt, high pressure sodium. The Contractor shall verify luminaire lamp wattage that may be stated on the plans. High mast luminaires are 1000-watt high pressure sodium. The Contractor will be required to install new 250-watt, 400-watt or 1000-watt clear high pressure sodium lamps as indicated on the plans. The fixtures shall be cleaned and refurbished before re-installing. Any inoperative ballast shall be replaced. The luminaire is to be in good working order when re-installed.
686.02.3 Pole Foundations. Pole foundations are cast-in-place concrete. The removal
of the foundations shall be as detailed in other sections of the specifications. New foundations shall be cast-in-place as per Section 684 or as per plans.
686.02.4 Anchor Bolts. The Contractor will be required to install new anchor bolts.
Anchor bolts shall be galvanized as per ASTM A 123. The minimum yield strength of the anchor bolts shall be 50,000 psi. The new anc hor bolts shall be of the same design as the existing bolts.
686.03 Construction Requirements. All component parts of the lighting assemblies
shall be removed and relocated as shown on the plans and required by the new construction procedures. When an item is removed it shall be stored in a location approved by the Engineer. All items scheduled to be re-installed shall be safeguarded by the Contractor and shall be fully operational at the end of the project.
686.03.1 Branch Circuit Wiring. All existing wiring in place will be shown on the plans.
The Contractor shall verify the type and size. For relocation and maintenance purposes, splicing of permanent wiring will not be permitted. New branch circuit wiring shall be provided as detailed on the plans. Splices of permanent wiring are permitted in pole bases only. Temporary wiring may be spliced as needed. All wiring shall meet the requirements of the National Electrical Code (NEC). The re-use of existing conductors and conduit when relocating permanent wiring will not be permitted. New conductors, conduit, boxes, connectors, etc. shall be provided as detailed on the plans. New wiring installation and materials shall be as per specified for underground branch circuit elsewhere in these specifications. Temporary wire may be re- used as long as it meets the requirements of the NEC.
686.03.2 Maintenance of Service. The existing lighting system shall be maintained and
kept in operation during the duration of the project. The Contractor shall provide and install any and all materials required to keep the lighting system in operation through the duration of the contract. Existing disconnected underground circuit conductors shall be cut off 24 inches below grade and abandoned.
686.04 Method of Measurement. Relocation of existing lighting assembly will be
measured as a unit quantity per each. Reloca tion of existing wiring will be measured per linear foot.
686.05 Basis of Payment. Relocation of existing lighting assembly, measured as
prescribed above, will be paid for at the cont ract unit price per each, which price shall be
