U.S. Bank Stadium in Minneapolis, Minnesota. © Joe Aker, Aker Imaging.



The U.S. Bank Stadium is designed to host a variety of events, including NFL football, MLS soccer, NCAA basketball and baseball, high school sports, motocross races, concerts and conventions. At 1.7 million square feet, the stadium holds 66,200 seats, including 8,200 club seats and 131 suites.

Thornton Tomasetti’s structural engineering, façade engineering, construction engineering and kinetic mechanization design teams collaborated with the architect to design an innovative building that features a series of operable panels in a glass end-wall that pivot to provide natural ventilation and access to the west plaza.

The design team utilized Thornton Tomasetti’s parametric modeling techniques to perform slope optimization studies that have created one of the lightest structural steel stadium roofs in North America. The steeply lofted steel roof, a principal architectural feature, is designed to shed the Minnesota snow. A single monumental steel ridge truss spanning 970 feet along the length of the field provides the primary support for the roof structure. On one side of the ridge, the roof is clad with a clear ETFE system. At 240,000-square-feet, the transparent roof is the largest ETFE roof in the United States. The transparency affords panoramic views of the outdoors, allows natural light to infuse the interior of the stadium, and produces additional solar gain to warm the stadium. Excess heat vents out of the stadium’s peak as part of a coordinated sustainability strategy. The other side of the ridge features a traditional steel deck and membrane roof.

The seven-level superstructure consists of precast concrete seating units and cast-in-place concrete frames and concourses. The stadium includes field-level suites and club seats and a lower suite level that is be the closest to the field of any NFL venue.

The building is LEED Gold certified.

ETFE & Fabrics

The use of lightweight membrane structures can enhance design, budget and building performance – but only if their attributes are considered early in the design process. With the ability to span great distances, these systems are used in dynamic and sculptural forms and can be quickly modified to meet changing weather-related or programmatic needs by adjusting shading, thermal and aesthetic characteristics. Our façade engineering consultants are experts in the application of ETFE, fabric and tensioned membranes, from concept evaluation to integration of these lightweight systems into building skin designs.

Façade Materials & Systems


Operable systems provide flexibility of use of a space, increase energy performance and enhance occupant comfort. Ranging from retractable roofs to operable screens on a façade, they can open or enclose a space and increase or decrease sun exposure. Some are automatic; others rely on manual control. Many can be incorporated into other façade systems. Our engineers work with designers to create custom solutions for building envelopes that satisfy performance requirements while giving owners the visual and experiential effects they desire.

Façade Materials & Systems


A variety of metals are used to wrap a building’s skin: aluminum, stainless steel, copper and zinc are notable examples. Each has its own special characteristics and can be used as rainscreen cladding, open screens, overhead enclosures or decorative elements with an array of possible shapes and configurations. We have used metals in a variety or project types, ranging from new façades to innovative re-cladding of existing structures. Our understanding of each material’s physical properties helps us provide designers with unique solutions that fulfill their design visions.
