The Beijing National Stadium, also known as the bird's nest will be the main track and field stadium for the 2008 Summer Olympics and will be host to the Opening and Closing ceremonies. 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. The stadium will seat as many as 100,000 spectators during the Olympics, but this will be reduced to 80,000 after the games. It has replaced the original intended venue of the Guangdong Olympic Stadium. The stadium is 330 metres long by 220 metres wide, and is 69.2 metres tall. The 250,000 square metre (gross floor area) stadium is to be built with 36 km of unwrapped steel, with a combined weight of 45,000 tonnes. The stadium will cost up to 3.5 billion yuan (422,873,850 USD/ 325,395,593 EUR). The ground was broken in December 2003, and construction started in March 2004, but was halted by the high construction cost in August 2004.In the new design, the roof of the stadium had been omitted from the design. Experts say that this will make the stadium safer, whilst reducing construction costs. The construction of the Olympic buildings will continue once again in the beginning of 2005. 北京国家体育馆，也称“鸟巢”，将成为2008年夏季奥运会主要的田径体育场，并在此举办开幕式和闭幕式。它在2002年，由政府官员从来自世界各地的建筑设计比赛作品中选中。普里茨克奖得奖建筑师赫尔佐克＆德莫鸿联合Arupsport以及中国建筑设计研究院共同赢得竞赛。奥运会期间，该体育馆将有多达100,000名观众入座，不过，奥运会之后将减少至80,000。它取代了原计划的广东奥林匹克体育场。该体育场长330米， 宽220米，高69.2米。 25万平方米（总楼面面积）大球场共建有36公里长的拆开包装的钢铁，总重量45,000吨。该体育场将耗资高达35.00亿元（ 422,873,850美元/ 325,395,593欧元）。2003年12月破土动工，2004年3月开始修建，但在2004年8月，由于建筑成本高昂停产，进行设计修改。 在新的设计中，体育馆的屋顶被做了简化。专家指出，这样做会令大球场安全，并且降低施工成本。建造工作将在2005年年初重新启动。

Beijing National Stadium also known as the National Stadium, or colloquially as the Bird's Nest, is a stadium in Beijing, China. The stadium was designed for use throughout the 2008 Summer Olympics and Paralympics. Located in the Olympic Green, the $423 million stadium is the world's largest steel structure. The design was awarded to a submission from the Swiss architecture firm Herzog & de Meuron in April 2003, after a bidding process that included 13 final submissions.

"Bird's nest" in the huge steel mesh Wai, covered with 9.1 million people in the stadium; sightseeing staircase naturally become an extension of the column disappeared, even force such as branches like no clear point, let a person feel every seat is equal, place oneself among them as back into the forest; the Sunlight filters into diffuse shaped inflatable membrane, made the stadium bid farewell to the sun shadow; the topographic uplift 4 meters. Inside the ancillary facilities, to avoid excavation the consumption of huge investment.“鸟巢”以巨大的钢网围合、覆盖着9.1万人的体育场；观光楼梯自然地成为结构的延伸；立柱消失了，均匀受力的网如树枝般没有明确的指向，让人感到每一个座位都是平等的，置身其中如同回到森林；把阳光滤成漫射状的充气膜，使体育场告别了日照阴影；整个地形隆起4米，内部作附属设施，避免了下挖土方所耗的巨大投资。The bird's nest is a large span curve structure, a large curved box structure, design and installation are very challenging, in the process of construction everywhere cannot do without the support of science and technology. The "bird's nest" with today's advanced construction technology, the whole project has twenty or thirty technical problems, the steel structure is the one and only the world. The "bird's nest" steel structure weighing 4.2 million tons, maximum span of 343 meters, and the structure is quite complex, the three dimensional twisted like fried dough twist processing, in after the construction of the settlement, deformation, loading and other problems are gradually resolved, related problems in construction technique is also listed as a key project of Ministry of science and technology.鸟巢是一个大跨度的曲线结构，有大量的曲线箱形结构，设计和安装均有很大挑战性，在施工过程中处处离不开科技支持。“鸟巢”采用了当今先进的建筑科技，全部工程共有二三十项技术难题，其中，钢结构是世界上独一无二的。“鸟巢”钢结构总重4.2万吨，最大跨度343米，而且结构相当复杂，其三维扭曲像麻花一样的加工，在建造后的沉降、变形、吊装等问题正在逐步解决，相关施工技术难题还被列为科技部重点攻关项目。
