Football Stadium Features Openings from ASSA ABLOY

Are you ready for some football? The Minnesota Vikings are, thanks to the efforts of ASSA ABLOY. The company readily met tight construction timelines to provide doors and hardware for 1,500 openings for the state-of-the-art U.S. Bank Stadium, where the team will play its 2016 football season.

The new $1.1 billion U.S. Bank Stadium encompasses 1.5 million square feet and 65,000 seats that will provide fans with the ultimate game experience. The stadium was uniquely designed to protect visitors from the elements, while maintaining a connection to the outdoors. Its most striking feature is a transparent roof that covers 60% of the facility, making it the largest ETFE (ethylene-tetra-fluoro-ethylene) roof in the country and the only one on a sports facility. 

A truncated time frame required suppliers to meet tight deadlines. The project was completed in just 30 months -- six weeks ahead of schedule – including demolition of the former stadium, the Metrodome. For context, another local stadium, Target Field where the Minnesota Twins play, was a project half the size, yet with a longer lead time. With 1,500 workers on site at the peak of construction, it was vital that ASSA ABLOY make its solutions turnkey.


A key component of success was pre-assembly of more than 1,000 openings constructed with ASSA ABLOY Architectural Door Accessories including McKinney hinges, Pemko accessories and Rockwood door trim; and products from Group brands including Curries hollow metal doors and frames, Sargent locks, exit devices and door closers, Medeco high security cylinders and keys, and Securitron access control components.

The construction manager working on the project had an existing relationship with Kendell Doors & Hardware, a distributor based in Mendota Heights, Minnesota. The construction firm consulted Kendell regarding the tight construction deadline. Kendell recommended teaming with ASSA ABLOY on the project and preinstalling the hardware to the doors to shave off valuable construction time. The construction firm agreed with the recommendation and the doors and hardware were all preassembled at the Curries manufacturing facility in Mason City, Iowa.

ASSA ABLOY’s ability to bring finished door openings to the site reduced the potential for incurring damage or lost goods around the busy, chaotic construction site, where palletized component hardware delivery wouldn’t have been efficient.

Pre-assembly also allowed the team to identify missing product so they could resolve issues before arriving at the site. The installation went almost flawlessly, with a punch list that was a tiny fraction of what it typically would be for a project of that magnitude.

While pre-assembly streamlined installation to meet the tight deadline, the features and benefits of the selected products addressed other needs. Aesthetics were a prominent requirement. The stadium design plans called for decorative hardware and trim to create a design continuum throughout the entire facility. ASSA ABLOY offered numerous aesthetic options with the Studio Collection levers from Sargent and matching hardware suites consisting of McKinney hinges and door pulls and Rockwood stops.

Although door openings would seem to be an insignificant design element in the overall appearance of a building, these small accents can make a big impression. Little details can be the finishing touch or, better yet, the starting point for building design. Doorways are intimate contact points between people and building and offer an opportunity to make a strong design statement.

Every building component could be considered a design element that enhances the visual satisfaction of walking down a hallway. So the traditional looking door opening  can really be viewed as a blank canvas—a slab of metal and/or wood waiting to be sculpted into a more dynamic form, an opportunity to maintain a design continuum throughout the building.

Now that durable, commercial-grade hardware and doors are becoming increasingly available with stylish accents, building designers can easily incorporate hardware into the overall aesthetic element of a building.  This makes it possible to have a design continuum throughout the entire structure. So if an office door needs one type of lock—say a mortise lock, and a bathroom door needs a different type of lock—maybe a tubular lock—the architect can go ahead and use different lock variations and not have to worry that the hardware used on one particular door will stand out or look different from those on other openings.

With this design flexibility, the stadium designers were able to specify locks and hardware that were both durable and good looking. Sargent 8200 series mortise locks vastly exceed ANSI Commercial Grade one strength and durability requirements, making them a perfect fit for the heavy game day traffic created by 65,000 high-energy football fans. Sargent 80 Series exit devices likewise surpass Commercial Grade one standards and are tested to withstand extreme abuse. Studio Collection levers and trim work with all Sargent locking devices, giving the perfect blend of aesthetics, strength and durability.

The complete opening package was rounded out with accessory hardware (hinges, gasketing, door pulls, stops, kick plates) along with a high security key system from Medeco.
