A pole foundation shall be a reinforced concrete foundation including the excavation, disposal of excavated material, concrete, backfill, concrete pad, reinforcing steel, conduit and elbows, anchor bolts, and mulching and seeding the disturbed ground. The compensation for a reinforced concrete foundation may be adjusted if the size of the foundation is required to be changed. Bid prices shall be given for the construction of a foundation to the depth and at the diameter shown on the plans. A deeper foundation may be required based on the results of the Department's review of the Contractor's submittal of the design of the pole structure. The compensation for a foundation will be adjusted if changes are required to be made to the depth of the foundation. The adjustments shall be in accordance with the following requirements: ROADWAY LIGHTING 657

shall be increased by $50 for each foot {$50.00 for each 300 mm} of depth that the foundation increases from what is shown on the plans.

shall be increased by $75 for each foot {$75.00 for each 300 mm} of depth that the foundation increases from what is shown on the plans.

shall be increased by $100 for each foot {$100.00 for each 300 mm} of depth that the foundation increases from what is shown on the plans.

shall be increased by $200 for each foot {$200.00 for each 300 mm} of depth that the foundation increases from what is shown on the plans.

depth shall also cover compensation for providing the reinforcing steel shown on the plans for the deeper foundations. The number and size of longitudinal reinforcing steel and the size and spacing of hoops will be the same regardless of any change in depth.

An electrical junction box shall be the junction box, concrete, and mounting hardware.

Conduit (RMC, LFMC, LFNC, or RNC) shall be the conduit tubing including fittings, trenching, backfilling, attachment to structure and miscellaneous hardware.

This shall be individual conductors and includes pulling, splicing, terminating, testing and miscellaneous hardware.

Nonmetallic Underground Conduit with Conductors (NUCC) shall be the complete assembly of polyethylene duct and the size and number of required conductors. It shall include fittings, trenching, backfilling, splicing, terminating, testing and all miscellaneous hardware.

A service pole shall consist of the pole, switch, fuses, ground rod, one-spool clevis, down guy and guy rod (if required) and miscellaneous hardware.

A lighting control center shall include switches, transformers, circuit breakers, contactors, fuses, enclosures, photocontrols, ground rods, incoming service conductors and conduit, concrete slab, anchor bolts, and miscellaneous hardware.

Equipment as specified, including miscellaneous hardware, shall be provided in new condition, and installed as required in the plan set. 11. Item 750-Z: Roadway Lighting. Roadway Lighting (lump sum) shall include all equipment, materials, tools, labor, and miscellaneous items required for roadway lighting as shown to be required on the plans. This shall include all excavation, foundations, conduits, conductors, pole assemblies, luminaires, junction boxes, lighting control centers, power service equipment and materials, and all miscellaneous items required to complete the work shown on the plans that is included in this item of work.
