Bird’s Nest

Bird’s Nest.

The National Stadium, affectionately known as Bird's Nest, is situated in Olympic Green Village, Chaoyang District, Beijing. It was designed as the main stadium of 2008 Beijing Olympic Games. The Olympic events of track and field, football, gavelock, weight throw and discus were held there. Since October, 2008, after the Olympics ended, the National Stadium has been opened as a tourist attraction. Now, it's the center of international or domestic sports competition and recreation activities.

The design of this large stadium was accomplished together by Swiss architects Jacques Herzog and Pierre de Meuron and Chinese architect Li Xinggang and the others. The designers didn't do any redundant disposals to the look of the stadium. They just exposed the steel structures entirely and let them become the most natural appearance. The form of the stadium looks like a big nest which embraces and nurses human beings. Also it looks rather like a cradle bearing human beings'  hope of the future.

The construction of the National Stadium started on December 24, 2003. On July, 2004, the project was stopped temporarily due to the amendment of the design. On December 27 of the same year, the construction was resumed and finished in March, 2008. The gross cost of the whole project is 2,267 million Chinese yuan (about 33 million dollars).  The stadium covers an area of about 258 thousand square meters (99.614 square miles), which can accommodate 80,000 fixed seats and 11,000 temporary seats. Its appearance was formed by big steel frames. Its top surface is saddle-shaped with the major axis of 332.3 meters (1,090 feet) and the stub axis of 296.4 meters (972 feet). The tallest point of the stadium is 68.5 meters (225 feet) above the ground and the lowest point is 42.8 meters (140 feet). The top is covered by semi-transparent air bubble film. This kind of material is waterproof and can make enough sunshine penetrate into the stadium. Owing to that, the lawns in it can grow well.

In the National Stadium, the designs of everything are humanistic. The bowl-like stands zone surrounds the court. The stands can be changed in many ways, which can satisfy the needs of different numbers of spectators in different periods. During the Olympics, the temporary seats were set at the top of the stands zone. Rows of the stands distribute scientifically. No matter where the spectator is seated, the whole game can be seen without any visual obstruction. The stadium adopted the electro-acoustic public-address system. It makes the index of voice definition reaches 0.6. This number assures that all the audience can hear the broadcast very clearly. What's more, there are more than 200 wheelchair seats intended for the disabled. Many architectural experts think that Beijing National Stadium not only is a symbol building of the 2008 Olympics but also set a very good example to the world's architectural history.
