Department of Veterans Affairs (VA) – Replace AHU V-15 Building 111Milwaukee, Wisconsin
Project Cost: $3.3 million
Completion Date: 2013
IBC Engineering was retained by the VA to provide design and construction support services for the replacement of the 110,000cfm AHU V-15 serving the 4th, 5th, 7th, 8th, 9th, 10th floors, A, B, C wings and, 3rd floor B wing at the Zablocki VA Medical Center. Work included modifying adjacent ducting, dampers, humidifier, filters, pre-heat, heating & cooling coils, and installing DDC controls for the new unit located in the hospital, Building 111. The project also included the addition of a new penthouse level constructed on top of the existing 11th story penthouse level.
After review of existing conditions and close examination of various options it was determined a one for one replacement of the existing unit in its current location within the 11th floor penthouse was not feasible. IBC’s recommendation to the VA was to construct a new penthouse on top of the existing penthouse. This option allowed the existing unit to be left in operation while the new unit was installed in the new penthouse. This option also accommodated the future replacement of the S-5 AHU located on the 10th floor of the hospital.
Given the critical nature of the building, IBC engaged the services of a Testing, Adjusting and Balancing Contractor to take airflow, sound and vibration readings during design to establish benchmark values for the design and final installation.
IBC acted as the prime consultant on this project overseeing Architectural, Structural and Environmental consultants.
