The value is listed as the highest possible cost from the range provided by a stakeholder or official project document. The objective ofthis project isto recommission the HVAC system throughout the facility and replace the facility's generator. The work to the HVAC system will require replacement of (and upgrades to) various parts of the system followed by a full Retro-commissioning (RCx) of the system as well as a complete Testing, Adjusting, and Balancing (TAB). HVAC: The existing boilers in the facility are to be replaced with two new condensing boilers. Accompanying the new boilers, all associated pumps are also to be replaced. This includes the circulating pumps on each boiler as well as the system's main heating water pump. New proportional valves and actuators are to be installed on all VAV boxes throughout the facility to replace the existing valves. A new ceiling and a dedicated exhaust system is to be added to the facility's Decontamination Room (room 402). This project requires the services of a full RCx team and TAB team to fully retro-commission and test, adjust, and balance the facility's HVAC system once all of the new system components have been installed. Electrical: The facility's generator is to be replaced with a similar unit capable of handling the necessary electrical load. Incidental to the replacement of the generator is the installation of a new equipment pad, automatic transfer switch, and any new wiring that needs to be ran for a complete and functional product. A factory startup by authorized personnel is required, at a minimum, to ensure the generator and electrical system work as intended. a) Demolish and remove existing boilers in the boiler room as well as their exhaust stacks, the heating water circulating pumps, and all associated HOA switches. b) Furnish and install two new condensing boilers that provide similar output to the existing boilers and are capable of handling the requirements of the facility. The new boilers must have BacNET controllers so the government can integrate them into the facility's controls system. Use the existing equipment pads, forming and pouring extensions to the pads if needed. The new boilers are to use combustion air from outside using the existing supply air ducts (verify that the size of the existing combustion air duct is adequate for the new boilers). Install new HOA switches for the boilers. Verify the existing wiring and breakers are adequate for the new boilers. Stagger the boiler installation to ensure that the facility has operable hot water at all times. c) Design, furnish, and install new boiler exhaust stacks that vent through the roof at a sufficient height above the roof to meet code requirements. Incidental to exhausting the boilers through the roof is cutting openings in the roof for the through penetrations. Add roof caps to the stacks, seal all roof penetrations, and flash the roof back in. Paint any disturbed areas to match surrounding colors. Coordinate with roof manufacturer/contractor (if applicable) to ensure the roof's warranty will remain intact. d) Provide aluminum block off plates and install them on both the interior and exterior of the boiler room where the old exhaust vents penetrated the walls above the doors. The exterior plate is to be sealed and then painted in a weatherproof finish to match the roof color of the facility. The interior plate is to be sealed and painted to match the surrounding walls. Ensure both plates are sealed with weatherproof sealant. e) Furnish and install two new heating water circulating pumps, one for each boiler. The new pumps are to be inline units and are to be similar to (and located in the same place as) the existing pumps. Install new wall-mounted HOA switches for each of the pumps in the location of the old switches. f) Demolish and remove the existing heating water pump in the mechanical room. This demolition and removal is to include the balancing valve situated in the heating supply water piping located just after the pump. Also demolish and remove the pump's existing HOA switch. g) Furnish and install a new base-mounted heating water pump on the existing equipment pad, forming and pouring extensions to the pad if necessary. Install a new balancing valve along with the new pump where the existing valve was removed. Install a new wall-mounted HOA switch for the new pump. h) Furnish and install new aluminum-jacketed HVAC piping insulation in the following areas throughout the facility, removing existing and/or damaged insulation as necessary: -Anywhere that existing insulation is removed as part of this project - Aboveground chiller piping in the mechanical yard where the chiller is located - On the section of overhead piping in the center of the vehicle bay that is currently exposed - On the vertical section of chilled water piping along the southern wall of the vehicle bay - Chilled and heating water piping above the ceiling in the laundry room where it is damaged and/or missing i) Remove all existing incremental valves on the VAV boxes throughout the facility. In their place, furnish and install new proportional valves and actuators on all VAV boxes that are compatible with the existing equipment and JCI controls system (0 -10V actuators) The new proportional valves shall utilize ball valves as opposed to gate valves. Leave existing controls wiring in place so that the new actuators can be hooked up and integrated. j) Coordinate the installation of the new proportional valves and actuators with the Government so that the EMCS team can hook up the actuators' controls wiring and integrate them into the controls system. Stagger VAV work with the government to ensure that they will remain operable when needed since the facility will remain occupied by personnel during this project and occupants live and sleep in the facility. k) Provide and install all necessary components to add a dedicated exhaust system to the Decontamination Room (Room 402) which maintains negative pressure per UFC 4-730-10. The suspended ceiling in Room 402 is to be replaced with a new drywall ceiling, including all necessary framing and finishing. Incidental to the installation of the new ceiling is the demolition of the suspended ceiling and 2' x 4' lights and the removal of all other fixtures in the ceiling including, but not limited to, sensors, monitors, and strobes. All items removed from the ceiling (except the lights) are to be reinstalled in the new drywall ceiling (and checked for correct operation) in similar locations once the ceiling is finished l) Furnish and install two new 2' x 4' surface-mounted LED flat panel lights in place of the previous lights. Reuse existing wiring and fixture whips where possible. m) In the new ceiling, furnish and install a new supply air diffuser and exhaust air vent. Furnish and install a supply air duct from the new diffuser up to the roof deck and through the roof. The supply air duct shall be penetrated through the roof and topped with a ventilating roof cap and/or back draft damper to protect the duct from the elements and still allow air to flow down into the room. Seal all roof penetrations and flash the roof back in. Paint any disturbed areas to match surrounding colors. Coordinate with roof manufacturer/contractor to ensure the roof's warranty will remain intact. n) Furnish and install a new exhaust air duct from the new exhaust vent in the decontamination room through the roof. Before running the new duct up through the roof, run it horizontal into the area above the ceiling of the adjacent laundry room. Install an exhaust fan in the duct at this location (for easy access and maintenance in the future) and then run the exhaust air duct up to the roof deck and through the roof. The fan should provide adequate airflow out of the room to maintain the necessary negative pressure when in use. The new exhaust fan is to be wired to the existing switch on the wall of Room 402 that is labeled "Exhaust Fan". This switch shall be rewired from its existing location on the BCU-1 switch in the laundry room to an electrical panel in the adjacent electrical room. Provide and install new conduit, wiring, and breakers as necessary. o) The exhaust air duct is also to be capped with a new roof cap and/or back draft damper to protect the duct from the elements and still allow air to flow out of the room. Seal all roof penetrations and flash the roof back in. Paint any disturbed areas to match surrounding colors. Coordinate with roof manufacturer/contractor to ensure the roof's warranty will remain intact. p) Furnish and install a wall-mounted electric unit heater in Room 402 since it will be blocked off from the heat provided by BCU-1. Install a dedicated thermostat in this room to control the unit heater. q) The walls and ceiling of Room 402 are to be entirely repainted. Incidental to this is the removal of all wall fixtures including but not limited to switch & outlet cover plates, the racks attached to the wall above the sink, soap dispensers, and air vents. Tape off anything remaining that cannot be removed. Prepare walls and ceiling for paint (i.e. filling in any holes and finishing) and add a base coat of primer followed by a minimum of two top coats. The finish coat shall be high gloss paint that matches the existing color of the walls in the room. Reinstall any previously removed items once the painting is completed.
