RFP Description:
VISN 6 NCO will issue on or about 04/13/2012 Request for Proposal (RFP) VA-246-12-R-0048, Replace Air-Conditioning System, B/74 (Design/Build). Contractor shall provide all labor, material, tools, equipment, transportation, design services, and qualified supervision for the design and construction for project 658-12-103. The intent of this project is to replace the existing heating and air conditioning systems in B/74 with a new, more energy efficient system. Work includes installation of a Variable Refrigerant Flow (VRF) system, Mitsubishi City-Multi or equivalent, to condition all interior spaces individually and includes associated electrical upgrades to supply power to the entire system. System shall be capable of simultaneously heating and cooling different areas within a zone, while recovering energy to reduce operating costs and increase capacity. Outdoor units shall be effective to -4 degrees F (W.B.) and 110 degrees F (D.B.). System shall meet ENERGY STAR Light Commercial Requirements and shall meet/exceed ASHRAE 90.1 2010 efficiency ratings. Individual spaces shall be independently controlled with programmable thermostats. System components include but are not limited to: outdoor units, branch/circuit refrigerant flow controllers, indoor units with local space controls, refrigerant line sets, condensate drains, insulation, energy recovery ventilators (ERV), ductwork, panelboards, safety switches/disconnects, conduits, firestopping, control wiring, direct digital control system (DDC), and controls interface fully compatible with the existing station HVAC/energy management system. Construction shall be phased, with up to 40% of work occurring after-hours (between 4:30 p .m. - 7:00 a.m.) to allow established work areas to remain functional. Existing work spaces shall remain conditioned until the new system is operational. Additionally, project work includes demolition, removal, and disposal of existing Building 74 Air Handling Units (AHU's), induction boxes, and ductwork that is not required for the new system. Existing chilled water system shall be capped at the ends of existing distribution lines and will remain throughout the building. Existing pneumatic controls shall be disconnected, with control lines to remain throughout For more details please visit: http://bit.ly/HNotfm To learn about all the energy incentives and projects available, check out www.energygridiq.com or download our iOS app Watt Rebate today.
