Ingersoll Building Sports Complex

City of Rockford

IMEG provided engineering design and services for the renovation and expansion of the Ingersoll Building into the UW Health Sports Factory, an indoor amateur sports complex. The project is part of Rockford Sports Reclaiming First, an initiative to redefine the city as a sports tourism destination.


The 98,000-SF complex features eight hardwood basketball courts that are convertible to 16 volleyball courts or wrestling mats, 42 pickleball courts, and areas for other hard-court sports. A mezzanine features concessions, flex rooms and bathrooms. Interior areas are convertible for use of flat space for trade shows and conferences. A court in the addition will serve as a larger venue for championship games.


Key engineering challenges stemmed from the adaptive reuse of the existing building (formerly an industrial manufacturing facility) and working with both the City of Rockford and the Rockford Park District. Other challenges included coordination of the suspended volleyball net system with lighting and air distribution systems, and large variations in building occupancy.


Design solutions include the use of multiple variable-air-volume rooftop air handling units to respond to the flexibility of occupancy. Other energy efficiency strategies include CO2 sensors to determine room occupancy levels, and destratification fans throughout the high-bay structure to redistribute already heated air from unoccupied ceiling spaces back to floor level.


Other key systems include: all-new electrical service with the capability to be connected to a portable generator; wireless control system for operating the basketball hoops, volleyball net and court partition systems, and wirelessly controlled scoreboards.
