PRESOLICITATION NOTICE- Install Dedicated Pharmacy Air Handler
Project Number 589A4-25-102

Scope of work:
The Harry S Truman Veterns Memorial Hospital in Columbia, MO requires the installation of three dedicated air handling units (AHUs) to bring the pharmacy and compounding, located in building one, in compliance with the latest VA HVAC Design Manual. The air handlers will serve the compounding area on the third floor, and the pharmacy and compounding areas in the basement.
The project design includes a new dedicated DOAS located in E002B in the Basement to serve the Compounding Suite in the Basement. There will be two new dedicated Air Handling Units in a new Mechanical space in the Southeast corner of the Second Floor Roof.
Construction Phasing
Installation of the new mechanical equipment will precede the demolition of the existing units. Temporary units will be provided for service while the first existing Mechanical units is demolished and removed. The same procedure will occur for the remainder of the Mechanical units.
Selective Mechanical Demolition
The main supply and return trunks serving the pharmacy and compounding areas in the basement will be demolished back to the plenum. The plenum will be patched and repaired. All but one VAV terminal units will remain in place. One VAV will be removed and prepared for relocation. The supply trunk supplying the compounding areas on the third floor will be partially demolished back to the last VAV on the trunk. Also, the supply trunk supplying the air flow control valves will require a partial demolition.
Proposed Mechanical System Description
There will be a new dedicated DOAS located in room E002B in the basement to serve the compounding suite in the basement. This AHU will be 4000 cfm with a chilled water cooling coil, steam heating coil, duct mounted humidifier, supply fan, two duct mounted pre-filters, a duct mounted after filter, and a duct mounted HEPA filter...
