PROJECT SCOPE: The Contractor shall furnish all layout, survey, plant, labor, supervision, quality control, materials, equipment, machines, tools, appliances, services, supplies, andincidentals required to remove two existing 13.8 kV circuit reclosers and install two new 13.8 kV circuit reclosers including associated controls and electrical connections. SPECIFIC DESCRIPTION OF THE WORK (DETAILS): a. Removal and installation of two 13.8kV circuit reclosers will require working in an outdoor energized overhead bus substation. The main switch station has a "Sparing-Recloser" configuration which allows one recloser to serve as a common spare for the four circuit reclosers. This will allow for replacement of the reclosers without a power outage. The existing circuit reclosers shall be removed and new reclosers installed one at a time. b. Sparing-Recloser (Circuit E) shall be replaced first and energized to ensure no problems/malfunctions existing with new circuit recloser installation. c. After Sparing-Recloser (Circuit E) has been installed and checked, then work may proceed to replace Circuit D recloser. During replacement of Circuit D recloser, new Sparing-Recloser Circuit E can be used to supply load for Circuit D. (Minor modifications to circuit recloser connection leads may be required to fit new recloser insulator). d. Coordinate work with Little Rock AFB's Base Maintenance personnel and local power company. Work shall be done in accordance with Federal Government Regulations/Procedures and National Electrical Safety Code. Delivery shall be FOB: Destination and all work shall be accomplished on site, Base Switching Station, Little Rock AFB, AR. MATERIAL SHIPMENTS: Little Rock AFB Base Civil Engineering Squadron will not receive material shipments for this project and Contractor shall not ship materials to himself addressed in care of Base Civil Engineering, Squadron, or Base Operational Contracting Office. Receiving and storage of material is entirely responsibility of Contractor. CLOSE-OUT PROCEDURES: A. When Contractor considers work has reached final completion, submit written certification that the contract documents have been reviewed, the work has been inspected, and that the work is complete in accordance with the contract documents and ready for final inspection. B. Provide the Contracting Officer with a requested date for final inspection, in writing, not less than two working days prior to the proposed date of final inspection. The Contracting Officer will coordinate with the members of the inspection party and establish the final inspection date. If construction deficiencies are identified, a request for reinspection must be given upon correction of the deficiencies. C. Deliver the two existing 13.8 kV circuit reclosers to a site on base as designated by Contracting Officer. FINAL CLEANING: A. Execute prior to final inspection., B.
