Specifications include, but are not limited to: Major elements of the project include: 1. Replace outside air (OA) air handling units (AHUs). Since exhaust fans and outside air dampers are also being replaced, use bi-polar ionization units to reduce amount of outside air 2. Evaluate feasibility of replacing indoor air units versus refurbishing. If refurbishing is more feasible, refurbishing existing units, including adding Bi-polar deionization. 3. Replace OA dampers and actuators 4. Replace exhaust fans 5. Upgrade existing Building Automation System (BAS) controls to manufacturer’s current technology 6. Refurbish cooling towers, including clean and balance fan blades, clean basin, replace gaskets, fan motors, float valves, variable frequency drives (VFDs), disconnects, chemical feed system, and select replacement of piping, valves, and insulation 7. Piping, insulation and select equipment replacement in the Central Energy Plant 8. Replace mini-split, direct exchange (Dx) air conditioning units in Main Distribution Frame (MDF) and Intermediate Distribution Frame (IDF) rooms and connect to BAS controls 9. Replace all VFDs, chilled water pumps, condenser water pumps, AHU water control valves, thermometers, controls and associated accessories. 10. Replace and upgrade elevator equipment and controls, including adding a minisplit air conditioning unit and replacing sump pump in the elevator pit 11. Replace VAVs and STUs with new VAVs, including electrical power revisions as needed 12. Replace duct heaters (configure to reheat) 13. Replace lighting, with either new LED fixtures or retrofitting existing fixtures to LED 14. Replace existing Fire Alarm System, including panels, field equipment and wiring 15. Replace existing Intercom System (retain existing speakers where functional) 16. Provide infrastructure for 32 existing and approximately 118 new digital cameras and replace existing cameras (new camera will be provided/installed by OCPS)
