An Olympic venue at steel mill shut down in former Shougang Industrial Park in Beijing in China, Big Air Shougang, has become the talk of the Beijing 2022 Winter Olympics after the freeski big air competition begun last week. Big Air Shougang has been built on the site of the former state-owned plant Shougang Group steel mill in Shijingshan District of Beijing. The sprawling campus has since been converted into a bizarre city oasis and is now the permanent home to the big air ramp. Rusting factories and machinery remain, but the space between has been filled by grassy lawns, glassy ponds and a good deal of greenery. One of the blast furnaces was given a facelift and turned into a steampunk-style event space with shops, commercial offices and a museum. The yards host dance showcases in the summer, and architects plan to transform one of the massive cooling towers hovering over the big air jump into a wedding venue.Chinese studio TeamMinus has designed a ski jump to host big air events at the 2022 Winter Olympics on the site of a former steelworks in Beijing. The largely steel structure designed by TeamMinus occupies a dramatic location alongside four large cooling towers on a strip of land between a former cooling lake and the Yongding River. As the 60-metre-long structure was designed to be used for big air events rather than traditional ski jumping, it has a distinctive form. Supported on a column that contains an elevator for the athletes to reach the top of the jump, the structure has three distinct sections. At the base of the jump, concrete stands with 2,500 permanent seats have been built around the landing area. The nearby Oxygen Factory complex is used as the entrance building for spectators watching the events, while the Beijing 2022 Organizing Committee moved its headquarters into a converted iron ore storage towers on the site in 2017.Created as the first permanent venue for big air events in the world, the 60-metre-high ski jump is hosting the ski and snowboard big air competitions at the Olympics. It is the first time ski big air has been included in the games, following the introduction of snowboard big air at the 2018 Olympics in Pyeongchang.
