Z1da--Replace Automatic Transfer Switches - Design-Build

Provide all labor, materials, tools and equipment, and the design-build services necessary for design and construction of a project described herein as well as other specific tasks as further defined by this Request for Proposal (RFP) the Design-Build Project No. 595-22-105, Replacement of Automatic Transfer Switches. The resultant contract of this procurement is to provide required design completion of the aforementioned project and perform construction of completed design work. Project shall be designed and completed in accordance with VA Criteria, EPA requirements, and VA Specifications developed for the project. The project is intended to replace THREE (3) non-by-pass Automatic transfer switches (ATS), with new ASCO 7000 series 4 pole ATS's with isolated bypass (ASCO 7000 series is a sole source requirement): • The project shall replace three (3) existing ATS’s in locations identified in Attachment “A” with new 4 pole isolated bypass ATS's. • New cables will be required from the sources and to the load. Splicing of existing cables will not be allowed. • Use of existing maintenance pads and/or electrical rooms will not be allowed as they are not sufficiently sized for the new ATSs. • Installation will be required to occur during times that will minimize impact to the patients, staff and hospital in general. • Collaboration between Design-Build team, COR and Lebanon VAMC Electrical shop will be required during the project. • All wire shall be stranded conductor unless it is equipment grounding conductor of #10 (number ten) and smaller. • No more than three (3) branch circuits per conduit. • #10 Wire on lengths greater than one-hundred feet (100’) and no more than one hundred and fifty feet (150’) for a twenty ampere (20 amp) branch circuit. • Electrical enclosures shall be supported individually. • All work shall comply with the National Fire Protection Association (NFPA) 70 (National Electrical Code), 70B, 70E, 72, 99, 101, and 13, and Occupational Safety and Health Administration (OSHA) regulations. • Conduits or raceways through which moisture may contact energized live parts shall be sealed or plugged at either or both ends. • Compression Fittings shall be used and wrench tight. • Everything that controls, consumes, or is capable of consuming electricity shall have a label. Label shall have circuit identification, panel it is fed from, and where the panel is located. • Neutral Conductor shall be identified with corresponding Phase conductor in all junction boxes and/or enclosures. Do not share neutral conductor. Neutral conductors shall be full size. • Metal Clad Cable shall not be used to connect devices horizontally through the wall; separate drops from the ceiling are acceptable to devices in the wall. • Phase Colors as follows: (Black, red, and blue for 120/208 volts and brown, orange, and yellow for 277/408 volts.) Neutral conductors shall be white in color for 120/208 volts and grey in color for 277/480 volts. • Wire nuts and splices shall not be allowed in any electrical panel. • There are five (5) ATS located within building 19, as a bid deduct option, the contractor shall provide an option for demoing all five and consolidating into three for reduced maintenance costs and operations.
