63,000 square feet football/soccer; 56,360 square feet baseball; 450,000 gross square foot enclosure Cast-in-place and precast concrete Teflon-coated translucent fiberglass roof

The project provides facilities for several Professional sports in an enclosed structure, seating up to 62,000 for Vikings football and Kicks soccer games, and up to 55,000 for Twins baseball games. Additional seating is provided in 115 private suites and on-field seating is provided for entertainment events. Team rooms and service areas are located on two partial levels below grade.

The 340-ton roof comprises two layers of teflon-coated translucent fiberglass fabric restrained and shaped by a network of 18 Steel cables anchored to a perimeter compression ring. While the outer layer of this fabric is completely airtight, the inner layer acts as an acoustic baffle, creating a thermal barrier and a plenum for the movement of warm air under the roof. Because air pressure must be maintained for roof support, all entrances are revolving doors.
