Ralph Engelstad, a former University of North Dakota hockey player and entrepreneur, donated the $104 million Ralph Engelstad Arena to the University. The arena is home to the University of North Dakota's Hockey team and hosts over 50 other events throughout the year including concerts, social events, and other family events such as Disney on Ice and the Shrine Circus. The arena can seat 11,640 for hockey games and 13,154 for concerts or large shows. The arena was constructed using high-end finishes as it includes granite concourse floors and all the seats are made of leather and cherry wood. The arena features 50 luxury suites, two club rooms, 264 club seats, a weight room, and an adjacent Olympic sheet of ice. The principals of ICON lead the design and construction of the original arena before the formation of ICON Architectural Group. The project had an 18-month construction schedule and was completed on time to be ready for the start of the 2001-2002 hockey season.
Most recently, ICON was hired to perform a 20 Year Capital Improvement Plan Forecast for the arena to help management allocate resources for future facility expenses. ICON has also installed new LED marquee signs on the roads surrounding the arena.
The arena is recognized all throughout the country and has even gained recognition from NHL players such as former hockey star, Wayne Gretzky, who called the arena "one of the most beautiful buildings we have in North America."
