U.S. Bank Stadium Opens, As Do the World’s Largest Pivoting Glass Panels
The ribbon-cutting and grand-opening ceremony for the new home of the NFL’s Minnesota Vikings takes place on July 22. The 65,000-seat stadium has many notable elements: a lightweight, steel-framed roof sloped to shed snow; 240,000 square feet of ETFE roof cladding to admit natural light; and a “prow” that stands nearly 30 stories high. But the venue’s signature feature is a series of huge glass-clad panels that pivot open to create an outdoor feel while protecting patrons from the elements.
The five panels, all 55 feet wide, vary in height from 75 to 95 feet. Each panel can pivot 90 degrees, powered by three pairs of hydraulic cylinders. Operable sills allow for a tight seal when the panels are closed, without leaving a tripping hazard when they are open.

A Building that Rides the Rails: The Shed
Courtesy Diller Scofidio + Renfro in collaboration with Rockwell Group.
The Shed, a new purpose-built cultural facility being built adjacent to 15 Hudson Yards in New York City, is designed to operate in various configurations. The structure will consist of two major elements: a six-level, 25,000-square-foot fixed building, and a telescoping outer shell that deploys over the adjoining plaza to provide a 120-foot-high hall that is light-, sound- and temperature-controlled. This flexible space can accommodate a standing audience of 3,000 or seating for 1,250.
The telescoping shell rolls out 114 feet along two rails. Installation of the rails began in late June, while other kinetic elements that drive the movable shell’s deployment will be put in place this summer and fall. The facility is scheduled to open in 2019.

Serving Up Support for a Retractable Roof at Wimbledon

July marks the start of construction for the redevelopment of the No.1 Court at The All England Lawn Tennis Club in Wimbledon. The project will add a new roof with fixed and movable components; increase seating capacity; create a new two-level public plaza; and upgrade concessions, catering areas and hospitality facilities.
We designed the fixed roof, the long-span movable-roof trusses, and structural modifications to support the redevelopment. Fitting new structural elements into the limited space available and accommodating a very constrained construction site added complexity. Generative modeling techniques were critical to the façade design, which features cladding for the roof and bowl elements that complements the geometrical aspects of the arena.
