Two unnamed companies competing to design the $1.3 billion Olympic stadium for the 2020 Olympic Games in Japan have released initial design proposals. Architect Zaha Hadid did the original design, but that was scrapped because of cost. The new designs are for an 80,000-seat stadium, and the work should be completed by Nov. 30, 2019.
Japan will host the 2020 Olympics, and it proposes to reuse three venues built for the 1964 Games. In addition, a new 80,000-seat main stadium will be built. Designed by Zaha Hadid, it will include a retractable roof and incorporate "futuristic" elements. A slideshow gives a look at some renderings.
This slide show highlights the design and engineering of the sporting venues and structures used for the 2012 London Olympic Games. It includes the 80,000-seat Olympic Stadium, the Velodrome, the O2 arena and the ArcelorMittal Orbit. About 30,000 engineers and construction professionals spent 700 million manpower hours to finish the projects.
Thousands of buildings in New York City have pursued environmentally friendly construction, but only 161 have managed to achieve the LEED certification. "For the amount that you hear about green buildings, there are only a small number of buildings that have reached that threshold," said Russell Unger, the executive director of the U.S. Green Building Council's New York chapter.
London's Olympic Stadium will get the first section of its roof fitted this week. A British plant provided up to 200 tons of steel cables for the roof. "London 2012 is a key part of the government's economic recovery plan providing jobs, training, and billions of pounds worth of contracts for U.K. firms," said Tessa Jowell, Olympics minister.
