GEC completed the 3M Arena at Mariucci (formerly the Mariucci Arena) at the University of Minnesota. The Arena is a 9,600-seat facility designed for the University of Minnesota Golden Gophers’ Hockey Team. As a single bowl seating configuration designed for the sole purpose of NCAA hockey, each seat provides an optimum viewing experience increasing the spectator experience. This design provides an ideal teaching and working environment for the players and coaches. The facility features a 240 seat "Gold Room" with superior sight lines for University Alumni, and an open concourse at the top of the seating bowl allowing visual continuity and accessibility for large spectator events.
The facility was designed in collaboration with Opus Corporation and Opus Architects and Engineers of Minneapolis. The Arena was the first design-build project undertaken by the University of Minnesota. Utilizing conventional construction techniques within a tighter time frame, the design-build format allowed completion of the project $3,000,000 below original projected costs.
For over 24 years the arena has functioned as a premier University athletic facility receiving praise from athletes, coaches, and spectators, and sports authorities. In 2007, 14 years after completion, Sports Illustrated ranked it a Top 10 College Sports Venue.
