859 – INTELLIGENT TRAN SPORTATION SYSTEM (ITS)
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, including concrete and soil from the project and dispose on sites approved by the Engineer or assume ownership and dispose of off of the right of way. Reseed and mulch the areas disturbed by the excavations. Hand seeding methods may be used. Do not use cinders, broken concrete, broken rock or other hard or undesirable material for backfilling.
improvements removed or damaged during installations of the Intelligent Transpor tation System. Replace or reconstruct the removed or damaged improvements with the same type and quality of materials originally used. If part of an existing slab of concrete pa vement or square of sidewalk is remove d or damaged, replace the entire slab or square. Replace damaged improvements as soon as practicable. Completely repair the ditch and replace the disturbed aggregate ditch liner if co nstruction activities disturb any aggregate ditch. Do not let rocks or aggregate fall into the trench prior to backfill.
Hold conduit ends and anchor bolts securely in the proper positio n when the concrete is placed. Cure the concrete foundations with wet burlap or polyethylene for a period of 72 hours. Prevent concrete temperatures from falling below 32ºF. Do not attach poles or cabinets until the concrete has cured for 14 days. Construct foundations in one pour. If a foundation cannot be constructed as shown in th e Contract Documents because of an obstruction, Contractor will submit to the Engineer for approval, an alternate method to construct the foundation. The top of the pole foundations shall be 2 inches abov e the finished grade if lo cated in a non-paved area. Concrete work aprons around equipment cabinet foundations shall be 1 inch above the finished grade if located in a non-paved area.
drilling holes for screw-in foundation anchors is prohibited. As the foundation anchors are screwed into the ground, make sure they 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 (maximum 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.

fittings as shown in the Contract Documents, where condu it crosses an expansion joint in the structure. Provide each expansion fitting with a bonding jumper of No. 6 A.W.G. copper wire or equal.
etc. Do not splice cable in conduit or outside of pull boxes, splice boxes or standards, unless shown in the Contract Documents. When not fastened to existing structure or carried through conduit, lay conductor cable to the depth shown in the Contract Documents. 859 – INTELLIGENT TRAN SPORTATION SYSTEM (ITS)

sheaths, conduit and metal standards to form a continuous system, and effectively ground. When an open system such as an overhead wiring or direct burial underground is used, effectively ground only standards and service points, except where conduit runs used under pavement cross a water system. Install ground electrodes as sh own in the Contract Documents.

859.4MEASUREMENT AND PAYMENT
The Engineer will measure the Intelligent Transportation System by the Lump Sum. All utility hookups, utility transformers, excavation, b ackfilling, Grade 3.0 concrete and testing for the Intelligent Transportation System are subsidiary. Payment for "Intelligent Transportation System" at the contract unit price is full compensation for the specified work.
