Mitchell Park Greenhouse Facilities for The Domes of Milwaukee County is located at 524 S Layton Blvd, Milwaukee, WI. Hunzinger served as construction manager for this 60,000 square foot new construction addition of seven new industry standard climate greenhouses, a storage prep facility and a connector link building that brings together the new facility with the iconic public domes of Mitchell Park adjoining between the Arid and Tropical Domes. The greenhouses were designed by Nexus, a manufacturer of highly specialized greenhouse facilities.

The seven greenhouses have a radiant floor heating system for primary heating that utilizes two high efficiency low condensing boilers. A building automation system for greenhouses called ARGUS integrates irrigation and misting systems, secondary unit heaters, grow lights, ventilation, and shading. Each greenhouse includes a solar shade system to reduce the sun light emission. Six of the seven greenhouses have an integrated black out shade system to force plants into dormancy. Cooling pad systems have been installed when the shading and ventilation systems cannot keep the greenhouses cool. (4) 20,000 gallon underground tanks store stormwater to be used for watering reducing the use of City water. A Storage Prep building contains a lab, cold storage room, a small kitchen, loading dock and offices.

On behalf of Milwaukee County Parks I would like to extend my sincere thanks to Hunzinger Construction for providing excellent construction management services on the Mitchell Park Greenhouse Project.  Andie Rodenkirch has been an integral team member and leader, successfully guiding our complicated project through a variety of unforeseen field conditions as well as managing the needs of a diverse team of stakeholders.  As a project that required both construction of the new facility as well as integration of the dynamic growing systems the Parks Department relies on, we have appreciated Hunzinger’s building expertise and professionalism.  The extensive construction schedule proved to be a challenge that Andie helped us through whether it was by leading weekly project meetings or providing detailed budget reports.  All in all, Hunzinger has provided Milwaukee County with excellent service, thank you!
