Correct Electrical Deficiencies

SOW 565-22-500 Correct Electrical Deficiencies Fayetteville VAMC Intent The project consists of correcting electrical deficiencies as noted from previous VA facility assessments. Improvements include; New electrical entrance building, medium voltage loop replacement, replace electrical distribution equipment, ground conductor corrections, incidental electrical equipment cleanup throughout the Fayetteville VAMC, and minor HVAC and Plumbing improvements. Period of performance 1,174 calendar days. Medium Voltage VA owned medium voltage loop and entrance equipment will be modified or replaced with the following scope: Replace existing medium voltage entrance equipment with new at campus entrance. Provide new building: Slab on grade, brick on CMU wall, Slate roof tile (to match existing facility) Provide new VA owned medium voltage cables in concrete encased duct bank for medium voltage loop. Approximately 300 . Demo and remove old VA owned medium voltage entrance metal shack. Replace medium voltage sectionalized switch. Provide new metal-clad switchgear with draw-out vacuum circuit breakers. Replace medium voltage oil filled transformer (1) Panel Replacement and Branch Circuit Improvements Correct deficiencies to electrical panels and branch circuit wiring which are not correctly sized, protected, or are at end of useful life, as identified through various inspections over the years. o All work will be phased. All replacements to existing equipment will require the contractor to filled-out a phasing plan for VA approval. All replacements to existing equipment will require a temporary power solution to minimize electrical outage to existing areas. Such deficiencies include: Replace-in-same-room building entrance and large distribution equipment: Normal (service entrance) Switchboards: approx. 2 Generator switchboards: approx. 2 Automatic transfer switch: approx. 7 Replace-in-place distribution panels and panelboards distribution equipment Distribution Panels: approx. 5 Panelboards: approx. 68 Replace undersized feeders Redundant Gound Provide redundant equipment grounding conductor to a portion of the facility. Approx. 100,000 square feet of existing electrical branch circuit distribution in occupied space. HVAC And Plumbing Reroute (vertically & horizontally) Sewer piping and hot water piping to avoid electrical room. Provide exhaust fan to new Medium Voltage building. Incidental Electrical Equipment Cleanup Provide Identification tag to new and existing equipment throughout the facility: approx. 100 tags Clean debris from existing electrical enclosures throughout the facility: approx. 30 enclosures. Correct panel grounding, terminate cable directly to existing panel’s ground bar: approx. 30 panels. ALTERNATE NO.1: BASE BID except delete Bldg 1, Floor 1 and Floor 3 of deficiency item 134 which directs the contractor to provide ground conductors in existing conduit. Which is noted on Sheet B01-E200.
