ProHealth Care - Mukwonago

Commercial HVAC, Plumbing & Building Controls Services for Hospitals in the Milwaukee Area


Ahern completed its work on time at the ProHealth Care facility in Mukwonago, Wisconsin. This facility is uniquely designed as it was built with a newer technology to the market called a “voided deck”. The concrete precast floor and roof had basketball-sized plastic balls embedded in them that acted as filler to replace what would be concrete.  It made the structure lighter while still maintaining its desired strength.


Ahern’s job was to install the HVAC and plumbing for the 65,000 square foot Emergency Department addition. HVAC consisted of new hot water boilers, a steam boiler, new air handling unit, new water-cooled chiller and cooling tower, propane fuel tank system, diesel fuel tank system, underground radiant snowmelt system, pumps, ductwork, VAV (variable air volume) boxes, piping, and Direct Digital Controls (DDC).  Plumbing included medical gas equipment and piping, typical fixtures, and a deionized water system.


Ahern’s prefabrication abilities helped keep the crews working in an efficient manner to meet the nine-month deadline, along with integrated work plans for specific tasks so that they were executed safely and efficiently.
