Allianz Field is a 19,400-seat capacity soccer stadium built in Saint Paul, Minnesota, for Minnesota United FC, the city’s Major League Soccer club. The $250 million stadium was designed by the renowned sports architecture firm, Populous, with assistance from engineering firm Walter P Moore. The stadium features a brilliantly simple design consisting of a membrane façade wrapped around the undulating steel framework. The completed building has a sleek, modern aesthetic that appears quite different from day to night. PFEIFER’s scope of work on the stadium involved the fabrication and installation of the 93,540 square foot tensile membrane façade. The membrane wrapping around the stadium is a uniquely developed PTFE membrane material that reflects sunlight and appears silver during daylight hours yet appears translucent at night. The steel support structure behind the building envelope includes 1,700 embedded computer-controlled LED lights capable of displaying dynamic light shows on the membrane façade.
