Beijing Olympic Games 2008

The “Bird’s Nest“, as the Beijing National Stadium is also known because of its very distinct structure, has its 80,000 seats been installed on the stands.
The National Stadium will host the main track and field competitions for the 2008 Summer Olympics as well as the opening and closing ceremonies. It is located right next to the Beijing National Aquatics Centre.
In 2002, Government officials engaged architects worldwide in a design competition. Pritzker Prize-winning architects Herzog & de Meuron collaborated with ArupSport and China Architecture Design & Research Group to win the competition.
Made of modified polypropylene, the seats have shown excellent performance in flexural strength and impact strength tests, and the colors of the seats will remain fade-resistant for three years under ultraviolet radiation, according to the construction company.
