810.04 Construction Methods
Construct power supplies in accordance with the NIST Handbook 81 Safety Rules for the Installation and Maintenance of Electric Supply and Communication Lines. Cooperate with the local utility companies to locate, ins tall, and connect power supplies. Contact local “Excavator Alert” organizations before starting trenching or boring operations.
A.Voltage and Construction Specifications Ensure the voltages for the permanent or temporary service poles are as shown on the Plans. Construct concrete in accordance with Section 509, “Structural Concrete.” Construct reinforcing steel in accordance with Section 511, “Reinforcing Steel for Structures.”
B.Temporary Power Suppl ies Arrange for electrical power connections for the temporary service poles as soon as construction allows. Arrange power connections for locations not shown on the Plans through the local utility company, with the approval of the Resident Engineer. Erec t, energize, deactivate, and remove the temporary lighting system at various stages of the traffic control as shown on the Plans or as directed by the Resident Engineer. Space the temporary lighting on wood poles 150 ft [50 m] apart. Protect the light pol es from traffic as approved by the Resident Engineer. Do not use aerial conductors to connect power to light poles with breakaway bases. Install the temporary light and service poles. Repair damage from installation, relocation, or removal at no additional cost to the Department. Maintain all existing lighting systems during construction in accordance with Subsection 105.14, “Maintenance During Construction,” at no additional cost to the Department. If a lighti ng pole assembly is damaged or knocked down by a third party, repair or replace the damaged lighting pole assembly to its original condition. The Department will pay the additional cost at the contract unit price for pay items necessary to complete the re pair or replacement, excluding removal of the light pole and concrete footing. Connect the temporary service poles to the permanent service poles for final acceptance after completing the lighting system or Project. Carefully handle items shown on the Plan s for removal, resetting, or both. Neatly store the removed items in a location directed by the Resident Engineer. Removed service poles, light poles, mast arms, luminaires, and temporary lighting equipment become the property of the Department. Stockpil e these items at locations shown on the Plans, unless otherwise approved or directed by the Resident Engineer.
810.05 Power Supplies
Leave the temporary service poles and the temporary lighting systems in place, or remove at the end of the Project, as directed by the Resident E ngineer. If temporary service poles or temporary lighting systems provide a safe driving environment, leave in place as approved by the Resident Engineer.
1.Temporary Lighting on Wood Poles Supply electrical service to temporarily light traffic control crossovers, points of conflict, and other locations as approved by the Resident Engineer.
2.Existing Lighting Circuits Maintain existing lighting systems in operation. If construction disrupts an existing lighting system, use additional temporary lighti ng on wood poles.
3.New Permanent Lighting Circuits Use the temporary lighting service and the temporary service poles to supply electricity to the temporary lighting poles and the new permanent lighting circuits. After Project completion, connect the p ermanent service pole to the new permanent lighting circuits. Install the permanent electrical service for the new highway lighting systems as shown on the Plans.
