Wiegmann Associates has completed HVAC work as part of an $18 million renovation and expansion project for the Brentwood School District in St. Louis, MO. As the installing mechanical contractor, Wiegmann upgraded HVAC systems at the Brentwood High School and Middle School campus and installed new systems for a 17,000-square-foot expansion. K&S Associates was the general contractor and the architect was Ittner Architects.
As part of the plan/spec project, Wiegmann replaced the interior components of the existing HVAC systems and entirely updated the HVAC systems in some of the buildings. Working with the existing infrastructure was a primary project challenge, along with project phasing, which was made more difficult by the pandemic. The configuration of the school district’s existing mechanical systems was especially complex because each building is conditioned with a different type of HVAC system from water source heat pumps and heat recovery units to rooftop units with Variable Air Volume (VAV) units.
Wiegmann installed a new HVAC system to serve the expansion built between the high school and middle school. The main floor of the addition creates a new primary school entrance and features a modern reception area, multipurpose space, common area, concession stand and spirit store. The lower level houses a new fitness facility and the upper level features a flexible classroom and library with workstations.
Wiegmann coordinated with the city of Brentwood and the neighborhood to close off streets while a crane installed new rooftop equipment. Since work had to be completed while school was in session, Wiegmann worked behind barricaded areas of the building and unoccupied floors and also completed some work after hours, on weekends and during school breaks.
