All measurements and distances are approximate and it is the Contractors' responsibility to verify those measurements and distances. Test results from 500V megger testing will determine what circuits need to be replaced. The Contractor will be responsible for locating pull box 23 on the right side and removing all debris, ensure drainage is clear, that may be inside that pull box before making repairs/test to electrical system. The Contractor will disconnect the lighting circuits at the base of all lighting standards, poles, control panel, all pull boxes to test existing conductors, and verify from megger testing for grounds or short circuits. The total poles number of 16 and the total number of pull boxes is 11. All phasing in the pull boxes shall be maintained and checked for balanced loading upon completion, Contractor shall correct if needed, and phasing will start at the control cabinet. The Contractor shall use the original wire numbering/letter system on both ends of the conductors in pull boxes if none provided Contractor will re-label, color code, and each wire shall be numbered/lettered. Contractor will leave 6' slack on newly pulled conductors. From visual inspections there are approximately 7 ballast/bulbs to be replaced. The Contractor will install one government provided light pole with head making connection to a newly re-poured base where existing one is located on the right side roadway, Contractor will be responsible for demolition or modification of existing base. The Contractor will supply all needed pull box connectors that can't be reused, insulating materials (tape, etc), 32 fuses of FNQ-R-10, 32 breakaway fuse holders sets, any fuses and holder sets not used will be left with the government. All wire and any other construction debris resulting from the new installation shall be removed from government property and disposed of properly. The Contractor will also be responsible for supplying any material needed for rewiring and adding new breaker/breakers to separate the right side roadway light section into 2 separate feed circuits for high water conditions the lower section of roadway lights RUN2 (parking area) can be de-engirezed without the loss of the entire circuit. This will be done for circuit RUN2 leaving control panel in switchyard by wiring RUN2 to a separate breaker after the automatic photocell control to allow personnel during high water just to be able to open that breaker to open the circuit feeding RUN2 but allowing circuit to function as one unit when this breaker is closed. If deemed circuits need to be separated in pull box 1 or control panel the Contractor will be responsible for that work. An existing three phase circuit which runs from the Barkley power house to a control panel located in the northwest corner of the switchyard has been damaged and is to be replaced by the Contractor. This circuit currently leaves the power house through the switchyard cable gallery in cable tray. At a point just after the gallery enters the switchyard the cables exit the gallery and run underground through an existing approximately 180' long, 3" diameter conduit, to a disconnect panel located in the northwest corner of the switchyard. The Contractor will be responsible for verifying measurements, sizes, and locating any piping, conduit, ground matt, etc. located in the switchyard. When the Contractor has begun to excavate and the conduit is uncovered it will need to be sampled by the Contractor to see if it contains asbestos and reports giving to the COR to determine options listed below. If during excavation the ground grid or any existing piping in the switchyard is damaged, it will be the Contractor's responsibility to repair the damage immediately according to procedures on the existing switchyard drawings. Repairs to the ground grid shall be made using cad-weld connections. The conduit shall be replaced with 3" PVC coated rigid steel. The conduit is to be installed at 0.5% grade. The cables shall be replaced with three new 4/0 type XHHW cables and shall run continuous from the Main Aux. Bus located in the power house to the disconnect switch which is located in the switchyard (approximately 700 linear feet or 2200 cable feet). This distance is to be verified in the field by the Contractor before the purchase of any materials. All conduit joints shall be made watertight using a thread sealer recommended by the conduit manufacturer. The penetration of the conduit into the cable gallery shall be made watertight using epoxy grout followed by painting the area on the outside of the concrete gallery around the penetration and several feet of the conduit with Black Jack Rubr-Coat #57 or approved equal. After the new conduit is installed, the Contractor shall backfill the trench with compacted impervious material to prevent surface water from entering the conduit and cable tunnel and the last one foot covered with new dense grade gravel to prevent growth of vegetation. It will be the responsibility of the Contractor to remove and properly dispose of any excess backfill material from the site or use as fill for other areas under the direction of the COR. 4. DETAILS OF WORK LEFT ROADWAY LIGHTING: Drains shall be installed on one side and below the bottom elevation of Pull Boxes 16, 20, 24, 27, 51, 52 with a weep hole at least 2" in diameter for drainage. The weep holes shall have a 2" PVC sleeve extending into the #3 sewer rock with a screen mesh over the opening within the pull box. The Drain shall be 18" wide, 18" deep, 6' long and start 15' beyond the end of the pull box. Three 4" perforated pipes shall be installed in a bed of #3 sewer rock with a filter fabric cover (See exhibit 7). All disturbed areas shall be backfilled, seeded, and re-vegetated and established. Left over material will be used to address settled areas around other pull boxes to level grade. Original drawings and visual inspections shall be used to determine the location and direction of existing conduits between pull boxes so as to avoid damage to any underground pipes. Pull box 11 will follow specifications as above with the following exception; the drain will be 36" wide, 36" deep 10' long and will start 30' beyond the end of the pull box to the south. Pull boxes 13, 14, 19, 21, 25, 28, 29 will need straight drains to graded side (day lighted) approximately 15'-50' from pull box consisting of 2" PVC sleeve extending out of ground cut level with the ground; with a screen mesh over the opening within the pull box. On all day lighted drains, guards will be added to prevent entry of any animal or debris back into the drain. Pull box 1 will need a 2" PVC drain running to the existing 12" storm drain connecting approximately 75' with a screen mesh over the opening within the pull box. The Contractor shall repair any damage to the 12" storm drain if encountered during installation of PVC drain connection, this repair must be detailed in writing and submitted to the COR before any repairs made. Contractor will insure that all drainage is at a slope or angle to insure that water does not pour or stand in the pull box or piping the desired angle will be no less than 3" in 25' except in pull box 1 which shall be no greater than 1% slope.
