National Stadium

Beijing National Stadium, officially the National Stadium, also known as the Bird's Nest, is a stadium in Beijing. The stadium (BNS) was jointly designed by architects Jacques Herzog and Pierre de Meuron of Herzog & de Meuron. The stadium was designed for use throughout the 2008 Summer Olympics and Paralympics and will be used again in the 2022 Winter Olympics and Paralympics.

Construction of the stadium proceeded in several distinct phases, the first phase involving the construction of a concrete supporting structure upon the concrete foundations laid for the construction site. This was followed by the phased installation of the curved steel frame surrounding the stadium, which is largely self-supporting. This phased installation involved the interconnection of sections of the curved steel frame that were constructed in Shanghai and transported to Beijing for assembly and welding. The entire structure of interconnected sections was welded together as the primary means of interconnection used to assemble the entire surrounding nest structure. Upon removal of the supporting columns used for the purpose of expediting the assembly of the interconnecting sections, the completed nest structure as a whole settled approximately 27 cm to attain full stability before the interior design and construction of the stadium could be installed and completed.
