Mayo Clinic Event Center

The ice system for this multi-purpose, 4,500-seat venue constructed in 1995 was in need of replacement. The existing Holmsten direct R-22 ice system was failing and the risk of compromising ice quality for the Division 1 Collegiate Maverick hockey team was not an option. In addition, the City was looking to provide an interior face-lift to this aging facility by replacing seating, the dasher board system and painting. B32 Engineering Group led an experienced team of consultants to provide the specialized services and leadership required to design and manage this critical project. B32 Engineering Group successfully scheduled and managed the three main projects under three separate contracts while allowing for dry floor events to take place, on the rink floor, prior to the completion of the project.

The largest component of the project was replacing the heart of the facility, the direct R-22 ice system. After a thorough discussion on ice system replacement options, the City selected to modify the existing refrigeration system and replace the concrete rink floor reducing from 200’x100’ to 200’x89’. Complicating the project was piling the structural subslab systems located beneath the rink floor. These systems were modified to provide the necessary pipe trenches required for the new rink floor system. Experience in working with equipment rooms designed for direct ice systems proved valuable in making this smaller refrigeration room work with the new modifications.

The dasher board system was replaced with the latest technology and options to maximize player’s safety and spectator’s involvement and enjoyment including one of the first acrylic and flexible clear post support systems in collegiate hockey. The system was designed to easily accommodate the removal and reinstallation of the dasher boards for dry floor events. Both the fixed and retractable seating systems were replaced with new lower maintenance and brighter seating systems. With careful planning, surveying of existing
infrastructure, clear communication, and; continuous monitoring, scheduling and surveying as the project progressed; the project was completed on time for the start of the 2014 hockey season.
