Beijing 2008

THE PROJECT

Right from the Candidature Phase for the 2008 Summer Games, it was planned to construct a multipurpose stadium capable of hosting national and international sporting and cultural events. The stadium would be the centrepiece of the Olympic Park, as part of an extension of the central zone used for the Asian Games in 1990 in the north of the city.

In late 2002, an international competition for the design of the stadium was launched. The winning project was selected in 2003. In 2004, following a cost revaluation, the idea for a retractable roof was abandoned, leading to a 22.3 per cent reduction in the quantity of steel initially envisaged.

ARCHITECTURE

The stadium’s enormous, saddle-shaped elliptical structure is composed of exposed criss-crossing steel beams, forming the external envelope. Although the arrangement appears random, this framework, with elements supporting one another, was designed on the basis of a geometric plan. While the original architectural inspiration for the design came from traditional Chinese crackle-glazed pottery and veined scholar stones, the building’s appearance earned it the famous nickname “Bird’s Nest”.

Between the interweaving structure and the inside of the stadium, the designers developed an autonomous “Piranesian”47 concourse space that resembles an artificial forest, with a thicket of supports and beams criss-crossing with platforms and access ramps. This space, which looks out onto the Olympic Park and the city, offers a place for restaurants and shops. The stadium benefits from natural ventilation.

The roof is covered with a transparent ETFE (ethylene tetrafluoroethylene) membrane, spanning 38,500m2, on the upper part, and a translucent PTFE (polytetrafluoroethylene) membrane, spanning 53,000m2, on its lower part. This double-layer membrane structure, in addition to being waterproof, allows light to flow into the stadium and improves the acoustics. A geothermal heat pump system absorbs the heat from the soil in winter and stores coolness in summer. A photovoltaic system generates enough power to light the 15,000m2 underground component. In addition, a rainwater collection and purification system is installed underneath the stadium. Water is collected on a 22-hectare surface, with an estimated annual volume of 67,000m3. The building is designed to withstand earthquakes measuring up to 8 on the Richter scale.


It certainly deserves a gold medal for innovation. Kelly Holmes British middle-distance athlete and triple Olympic medallist.
PARTICULAR FEATURES

The concept behind the atmospheric night lighting in the stadium was inspired by Chinese lanterns. An abundance of light glows from within the stadium, creating a powerful visual silhouette effect with the external beams.

AFTER THE GAMES

Events organised in the stadium since the Olympic Games have included the Race of Champions motorsport event in 2009, three editions of the Italian football Super Cup (2009, 2011 and 2012), a meeting on the programme of the IAAF World Challenge four consecutive years (2013 to 2016), the World Championships in Athletics in 2015 and the final of the League of Legends video game World Championship in 2017. In addition, the stadium has hosted concerts and winter sports events, including competitions in the FIS Freestyle Skiing World Cup in 2013, 2014 and 2015. The Bird’s Nest has also become a tourist attraction. The Opening and Closing Ceremonies of the Olympic Winter Games 2022, which will be held in Beijing, are set to take place in the stadium.

- After being deemed too small by some spectators during test events, the 28.3m2 screen located inside the stadium was replaced with two 66m2 screens.
