Gregory & Swapp Professional Office is a four-story office containing 74,924 sq ft. There is a secured, underground parking garage beneath the building that houses 52 parking stalls. The biggest challenge the design and construction team faced was the re-design of the HVAC system after the entire steel structure was completed. The project team identified that a more sophisticated and efficient HVAC system should be used. The original design would not provide the level of comfort and customization for the occupants/tenants based on where they were located in the building. This redesign required changes to the interior space layout as well as adding an additional boiler in an exterior enclosure.
