Wiegmann Associates is the mechanical contractor and Trine/Poettker joint venture is the general contractor. The plan/spec project involves removing the 50-year-old HVAC systems from Buildings 1, 51 and 52 and installing new, more energy-efficient equipment as well as new ductwork, piping and insulation. Building 1 houses the VA’s patient services, administrative offices and various medical clinics. Building 51 is used for mental health services and Building 52 features a chiropractic clinic as well as the spinal cord injury care and pain rehabilitation center. Wiegmann also is installing the HVAC system to serve a new rehabilitation facility, which is currently under construction and scheduled to complete in the Spring of 2020. Wiegmann previously installed the heating and cooling systems in the 67,000-square-foot Jefferson Barracks VA Engineering Warehouse. Poettker Construction was the general contractor for that project, which completed in 2018.
