800-45 Rural Utility Service (RUS)
Illumination Engineers Society (IES) Standards of the American Society for Testing and Materials (ASTM) American Accommodation Policy Local ordinances. Details in the Contract Documents. Before starting any work on existing street lighting an d circuits, obtain daily safety circuit clearance from the serving company. Before beginning work, pull cut-out plugs and warning signs posted at cut-out boxes.
b.General.
1.Provide and install all incidental parts not shown in the Contract Documents which are necessary to complete the electrical system or traffic signal or modify existing systems as shown in the Contract Documents. All utility hookups are subsidiary, unless shown otherwise in the Contract Documents.
2.Provide continuous welds that develop the full strength of the member. (3) Perform welds by the submerged arc process.
4.Grind exposed welds flush with the base material.
5.Smoothly finish all exposed edges of plates which make up the base assembly. Round all exposed corners of such plates to ⅛ inch radius.
c.Removals and Excavations. Perform removals of existing structur es and excavations to minimize damage to existing structures and right-of-way. Remove the existing concrete founda tions (including anchor bolts) to the elevation shown in the Contract Documents. Limit the excavation for the conduits, f oundations and other applia nces to that necessary for the installation of the equipment and materials. Do not excavate until immediately before installing the equipment and materials. Place plastic warning tape (12 inches below the surface) directly over conduit. Place excavated material where no damage and obstructi on to vehicles and pedestrian traffic will occur. Do not impede surface drainage. At the end of each day’s work and at all times wh en construction operations ar e suspended, remove all equipment and other obstructions from the portion of the roadway open for use by public traffic.
d.Backfill. Place the backfill material in uniform layers (maximum 6 inches compacted) evenly on all sides of the structure. Compact the backfill using pneumatic tampers, vibratory compactors or other equipment approved by the Engineer. Compact the backfill to comply with the Contract Documents. If backfill requirements are not specified, compact each layer until no further consolidation is observed. Remove surplus excavated material from the project and dispose on sites approved by the Engineer. Reseed the areas disturbed by the excavations. Hand seeding methods may be used.
e.Replacing Damaged Improvements. Replace all sidewalks, curbs, gutters, pavements and other improvements removed or damaged during installations of the lighting systems or traffic signals. Replace or reconstruct the removed or damaged improvements with the sa me type and quality of materials originally used. If part of an existing slab of concrete pavement or square of si dewalk is removed or damaged, replace the entire slab or square.
f.Foundations.
1.Concrete Foundations. Form the foundati ons and place the concrete according to DIVISION 700 . Hold conduit ends and anchor bolts securely in the proper position when the concrete is placed. Cure the concrete foundations with wet burlap or polye thylene for a period of 72 hours. Prevent concrete temperatures from falling below 32ºF. Do not attach poles until the concrete has cured for 14 days. If a foundation can not be constructed as shown in th e Contract Documents because of an obstruction, the Engineer will determine how to construct the foundation. 814 - ELECTRIC LIGHTING SYS TEMS AND TRAFFIC SIGNALS
800-46 (2) Screw-In Foundation Anchors. Pre-drilling holes fo r screw-in foundation anchors is prohibited. As the
foundation anchors are screwed into the ground, make sure th ey are plumb. The pole base of the screw-in foundation anchor shall be level when the installation is complete. Use the connectors to make minor leveling adjustments on poles with breakaway connectors. Use galvanized or cadmium plated shims or washers (m aximum thickness ¼ inch) to make minor leveling adjustments on other types of poles. Only 1 shim or washer is allowed on any 1 anchor bolt, with a maximum of 2 shims or washers on any pole.
3.Removal of Existing Foundations. Remove the desi gnated existing foundations to the depth shown in the Contract Documents. Backfill the resulting holes according to DIVISION 200 . Dispose of the removed foundations and anchor bolts.
g.Conduit.
1.Run all conductors between standard locations, either in duct or conduit. Use conduit of the size and type shown in the Contract Documents. If desired, use larger size conduit at no additional cost to KDOT. Use the large size conduit for the entire length of the run from outlet to outlet. Do not use reducing couplings. When PVC or HDPE is specified, install acco rding to the manufacturer’s instructions. When steel conduit is used, ream the ends of all conduits to remove burrs and rough edges. Make field cuts square and true so the ends will match for the full diamet er. Do not use slip joints or running threads for coupling conduit. Use an approved threaded union conduit, if a standa rd coupling can not be used. Before couplings are made up, paint threads on all conduits with a rust preventative paint. Fit and ti ghten all couplings until the end of the conduits are brought together. Paint any damaged coating on conduit with rust preventative paint. Thread and cap all steel conduit ends wi th standard pipe caps, until wiring is started. When caps are removed, provide threaded ends with approved conduit bushings. Except factory bends, use conduit bends with a radius of gr eater than or equal to 6 times the inside diameter of the conduit. Where factory bends are not used, make conduit bends without crimping or flattening, using the longest radius practicable. Mark the location ends of all conduit for future electric al circuits in structures with a "Y" a minimum of 3 inches high cut in the face of curb, gutter or wall directly above the conduit.
2.Conduit Entrenched. On electric lighting projects where possible, and on surfacing projects as shown in Contract Documents, install the electrical conduit on straight lines and cover with compacted earth. Place conduit as shown in the Contract Documents. (3) Conduit Jacked. Use TABLE 814-1 to determine the conduit depth. Place conduit under existing pavement by approved jacking or dr illing methods. Do not dist urb pavement without written permission of the Engineer. Keep jacking or drilling pits 2 feet clear of the edge of any type of pavement. TABLE 814-1: JACKED CONDUIT DEPTH Location Conditio n Minimum Depth Pavement 36 inches below top of pavement. Trenches on shoulder and in park areas 36 inches below natural ground level. Finished surface in street areas 36 inches below the street surface.* Railroad tracks 42 inches below top of tie. *Conduit may be laid on top of and secured to th e existing pavement in curbed dividing strips.
4.Vertically extend conduit set in standard bases a pproximately 3 inches above the foundation, or slope towards the base opening where transformer bases are used. Locate conduit entering through the bottom of a pull box near the ends to leave the major portion of the box clear . Terminate conduit entering concrete pull boxes 2 inches inside the box wall and 2 inches or greater above the bottom and slope to facilitate pulling of cable. At all outlets, enter the conduit from the direction of the run. For conduit carried through existing culverts or bridge st ructures, pick up the trenched cable for 3 feet in the ground and run up the face of the culvert headwall to the nearest upper corner or top, through the culvert, down the opposite headwall and into the ground for 3 feet. Fasten conduit to concrete su rfaces by means of approved clamps and fasteners. Clean existing underground conduit to be incorporated into a new system with a mandrel, and blow out with compressed air. Conduit runs shown in the Contract Documents may be changed with approval of the Engineer to avoid underground obstructions.
