Who built the Bird's Nest?

Question 1: Which company built the Bird's Nest? (Reporter Xu) On September 17, the world-famous national stadium-the world's largest span steel structure building "Bird's Nest" completed the steel structure unloading. This means that a world in the history of architecture was born. Half of the 48,000-ton steel structure of the Bird's Nest was built by Jiangsu Huning Iron and Steel Machinery Co., Ltd. in Yixing City. In the process of participating in the design and construction of the "Bird's Nest", Shanghai-Nanjing iron and steel workers gave one golden idea after another, and China Institute of Architectural Design and Research praised them as great heroes in the construction of the "Bird's Nest".

When the 2003 national stadium scheme passed the evaluation by experts at home and abroad, some foreign experts questioned:

"Can China people do it?" China experts present said confidently: Yes! China Architectural Design and Research Institute, the general contractor of the National Stadium Owners' Committee, invited Shanghai Steel Machinery to participate in the process design because of its outstanding performance in the world-class construction projects such as Shanghai Maglev Train and National Grand Theatre.

In the bidding of the first and second bid sections of the "Bird's Nest" steel structure project, Shanghai-Nanjing Steel won with the first total score.

Steel is the key to the success of the Bird's Nest. This world-class building needs top-grade steel. This kind of steel is an alloy steel called "Q460EZ35", which has both high strength and high toughness. This kind of steel has never been manufactured and used in China, and it is rare abroad. Most Chinese and foreign experts believe that it must be introduced from abroad. Wang, the chairman of Shanghai-Nanjing Iron and Steel Machinery Co., Ltd., believes that Henan Wuyang Iron and Steel Plant has the ability to produce this alloy steel based on his more than 20 years of steel structure construction experience and extensive understanding of domestic iron and steel enterprises. He strongly recommended it to the engineering construction unit. He said: "If domestic steel can be used, the national industry can reach a new level and save a lot of money for major national construction projects." Whether to use domestic steel or imported steel has become the focus of debate for a time. Wang actively contacted Wugang, allowing them to express their opinions on the construction site in Beijing and trial-produce high-quality alloy steel exceeding the foreign level. Finally, the construction unit adopted Wang's opinion and replaced the imported steel with WISCO's steel. The design and construction unit expressed admiration and appreciation for Wang's "golden idea".

The difficulty of the "bird's nest" lies in two aspects: one is that there are many contact points in the structure, and the other is that the steel plate is thick and particularly curved. The original design scheme used a large number of cast steel joints, which was heavy in weight and high in cost. How to solve this problem has become the trouble of owners. After analysis and comparison, the engineer of Shanghai Nanjing Steel Machine proposed to weld the contacts with steel plates. After scientific analysis, the construction unit thinks this is a "golden idea" and resolutely adopts the Shanghai-Nanjing steel machine scheme. As a result, more than 50 million yuan was saved. For the box-shaped bending and twisting parts with great difficulty, they combine traditional technology with modern numerical control technology to create a unique processing method for bending and twisting parts and create world-class appearance quality.

After the "Bird's Nest" scheme came out, the general contractor launched an international bidding for the hoisting scheme, and further improved the hoisting construction scheme of the "Bird's Nest" steel structure through brainstorming. Domestic and foreign 12 powerful construction units participate in bidding.

Shanghai-Nanjing Steel Plant has put forward a new scheme of "sectional assembly on the ground and sectional hoisting at high altitude". After theoretical analysis, Chinese and foreign experts finally decided that the Shanghai-Nanjing steel machine scheme was the only hoisting scheme. The practice after the implementation of this scheme shows that it has the advantage that steel structure hoisting and civil construction can be carried out at the same time, which greatly speeds up the project progress, improves the safety factor and saves 30% of the project cost.

Question 2: Who is the designer of the Bird's Nest? Bird's Nest Designer: The designer of the Bird's Nest

Swiss architect Pierre? Pierre Demeuron and Herzong.

The Olympic "Bird's Nest" witnessed China's heart.

Known as the "fourth generation gymnasium", the great architectural work "Bird's Nest" not only witnessed the unremitting pursuit of human beings in the field of architecture and human settlements in the 2nd/kloc-0th century, but also witnessed the historical process of China, an ancient oriental civilization, opening up continuously.

On June 25th, 2002, authorized by the Beijing Municipal People's Congress and the Organizing Committee of the 29th Olympic Games, the Beijing Municipal Planning Commission collected the architectural concept design scheme of the main stadium of the 2008 Olympic Games-China National Stadium.

The National Stadium is the first Beijing Olympic venue facility to enter the architectural design process. According to the introduction of Beijing Municipal Planning Commission, the national stadium architectural concept design competition is divided into two stages: the first stage is pre-qualification; The second stage is the official competition. By June 20th, 2002, 165438+ Competition Office had received valid prequalification documents from 44 famous design companies. After strict pre-qualification, 14 design companies were finally determined to enter the formal scheme competition, from China, the United States, France, Italy, Germany, Australia, Japan, Canada and Switzerland.

The Olympic Games not only attracted the greatest athletes in the world to create the best results, but also attracted the greatest architects in the world to create the greatest works. Many of the world's most powerful design teams and talented designers, including the winner of the Plic Award, the highest prize in world architectural design, participated in the competition. On March 8, 2003, 13 well-known architectural design companies and design consortia from all over the world finally participated in the competition, and delivered their grand ideas for China National Stadium to Beijing. 13 design scheme includes 2 domestic schemes, 8 overseas schemes and 3 Chinese-foreign cooperation schemes.

In the subsequent scheme evaluation, the evaluation committee composed of three authoritative figures, including Guan Guan, academician of China Academy of Engineering, Koolhaas, Dutch architect, etc. 13, made strict evaluation, repeated comparison and careful screening of the entries. After two rounds of secret ballot, three excellent schemes were finally selected. They are the "Bird's Nest" scheme designed by Herzog, De Mellon and China Architectural Design and Research Institute, the "Floating Roof" scheme independently designed by Beijing Architectural Design and Research Institute of China, and the "Sky Stadium" scheme jointly designed by Sato Comprehensive Project of Japanese company and Tsinghua University Architectural Design and Research Institute of China.

On this basis, the jury selected the "Bird's Nest" scheme by an overwhelming majority and recommended the implementation scheme. When discussing the "Bird's Nest" scheme, * * * 8 votes were in favor, 2 votes against and 2 abstentions, and 1 vote was invalid. It is rare for a scheme to gain so much knowledge in an international architectural competition.

In order to solicit public opinions, the organizers of the competition also exhibited all the 13 design schemes at the Beijing International Convention Center. The exhibition lasted for 6 days and attracted more than 6,000 votes from the audience. Among them, the "Bird's Nest" scheme recommended by Chinese and foreign judges won 3506 votes, the "floating roof" won 3472 votes and the "Sky Stadium" won 3454 votes, ranking the top three. "Bird's Nest" ranked first, which showed the recognition of the audience and the judges to a considerable extent.

After careful study by the decision-making departments, the "Bird's Nest" was finally determined as the final implementation plan of the main stadium of the 2008 Beijing Olympic Games-China National Stadium.

Meet the needs of the Olympic Games and attach importance to "post-Olympic development"

-not only to build historical buildings, but also to embody the concept of thrifty hosting the Olympic Games and lay the foundation for the implementation of "post-Olympic development"

Many people who have seen the design model of the "Bird's Nest" describe it as a warm bird's nest made of a stadium with a capacity of 65,438+10,000 people and a branch-like steel net! The "nest" used to nurture and take care of life places human hopes for the future.

Indeed, the components of the whole stadium structure support each other to form a grid-like frame, which looks like a bird's nest woven with branches. Its gray mineral-like steel mesh is covered with transparent film material, which includes a khaki bowl-shaped stadium stand. Here, the hollow-out technology, ceramic lines, the red brilliance and enthusiasm in China traditional culture are perfectly integrated with the most advanced modern steel structure design.

Amazingly, the whole building is connected by a huge network structure, without any columns inside, and the stands are complete without any shelter ... >>
