Work has been completed on the new $49-million rehabilitation facility at the St. Louis VA Medical Center-Jefferson Barracks, located in Missouri. The multi-building complex overlooks the Mississippi River in south St. Louis County and serves area veterans and their families. The project team included mechanical contractor Wiegmann Associates, general contractor Walsh/Alberici joint venture and architect Christner, Inc.
Wiegmann installed the energy-efficient HVAC system, including ductwork, insulation and piping, that serves the entire rehab facility, including the chapel, basketball court, pool, offices and rec rooms. To achieve the owner’s goal of energy efficiency, the HVAC system for this new facility utilized the existing campus chilled water and steam loops to feed heat into the building. Wiegmann also installed air handling units, fan coil units, air terminal units, unit heaters, exhaust fans, an energy recovery unit, direct heat recovery chiller, heat exchangers and steam humidification.
The limited space available for equipment posed a project challenge, which the team overcame through careful planning and coordination with other trades.
