This image is from BBC comparing the biggest buildings. You can't say they don't have a vision. Remarkably, the inspiration for the tower comes from - a flower. The Hymenocallis is a plant widely cultivated in Dubai , India and around the region. It's harmonious structure is one of the organizing principles for the design.
The striking exterior of the National Swimming Center , being constructed for the 2008 Olympic Games and nicknamed, the "Water Cube," is made from panels of a lightweight form of Teflon that transforms the building into an energy-efficient greenhouse-like environment. Solar energy will also be used to heat the swimming pools, which are designed to reuse double-filtered, backwashed pool water that's usually dumped as waste.
Excess rainwater will also be collected and stored in subterranean tanks and used to fill the pools. The complex engineering system of curvy steel frames that form the structure of the bubble-like skin are based on research into the structural properties of soap bubbles by two physicists at Dublin 's Trinity College . The unique structure is designed to help the building withstand nearly any seismic disruptions.
5. Central Chinese Television CCTV, Beijing OMA/Ole Scheeren and Rem Koolhaas. Under construction, scheduled for completion in 2008
The design of the new Central Chinese Television (CCTV) headquarters defies the popular conception of a skyscraper -- and it broke Beijing's building codes and required approval by a special review panel. The standard systems for engineering gravity and lateral loads in buildings didn't apply to the CCTV building, which is formed by two leaning towers, each bent 90 degrees at the top and bottom to form a continuous loop.
The engineer's solution is to create a structural "tube" of diagonal supports. The irregular pattern of this "diagrid" system reflects the distribution of forces across the tube's surface. Designed by Rem Koolhaas and Ole Scheeren and engineered by Ove Arup, the new CCTV tower rethinks what a skyscraper can be.
6. Linked Hybrid, Beijing Steven Holl Architects; Li Hu, lead architect. Groundbreaking on December 28, 2005 , scheduled for completion in 2008
Developed by the Shanghai Industrial investment Corp., Dongtan Eco City , roughly the size of Manhattan , will be the world's first fully sustainable cosmopolis when completed in 2040. Like Manhattan , it's situated on an island -- the third-largest in China . Located on the Yangtze River, Dongtan is within close proximity of the bustle of Shanghai .
By the time the Shanghai Expo trade fair opens in 2010, the city's first phase should be completed, and 50,000 residents will call Dongtan home-sweet-sustainable-home. The goals to be accomplished in the next five years: systems for water purification, waste management, and renewable energy. An infrastructure of roads will connect the former agricultural land with Shanghai .
8. Olympic Stadium, Beijing Herzog & de Meuron. Under construction, to be completed in 2008
Sports stadiums have long followed the enduring design of one of the original wonders of the world, Rome 's Coliseum. Herzog & de Meuron's National Stadium in Beijing is an attempt to rethink the classic sports-arena layout for more ecologically correct times.
The Swiss architects (of Tate Modern fame) wanted to provide natural ventilation for the 91,000-seat structure -- perhaps the largest "eco-friendly" sports stadium designed to date. To achieve this, they set out to create a building that could function without a strictly enclosed shell, yet also provide constant shelter for the audience and athletes alike.
To solve these design problems, they looked to nature for inspiration. The stadium's outer grid resembles a bird's nest constructed of delicately placed branches and twigs. Each discrete space within the facility, from restrooms to restaurants, is constructed as an independent unit within the outer lattice -- making it possible to encase the entire complex with an open grid that allows for natural air circulation. The architects also incorporated a layer of translucent membrane to fill any gaps in the lacy exterior.
9. Donghai Bridge , Shanghai/Yangshan Island China Zhongtie Major Bridge Engineering Group, Shanghai # 2 Engineering Co., Shanghai Urban Construction Group. Officially opened in December, 2005
10. National Grand Theater, Beijing Paul Andreu and ADP. Under construction, to be completed in 2008
Located near Tiananmen Square , the 490,485-square-foot glass-and-titanium National Grand Theater, scheduled to open in 2008, seems to float above a man-made lake. Intended to stand out amid the Chinese capital's bustling streets and ancient buildings, the structure has garnered criticism among Bejing's citizens for clashing with classic landmarks like the Monument to the People's Heroes (dedicated to revolutionary martyrs), the vast home of the National People's Congress, or Tiananmen Gate itself (the Gate of Heavenly Peace).
French architect Paul Andreu is no stranger to controversy -- or to innovative forms. A generation ago, in 1974, his untraditional design for Terminal 1 of Paris 's Charles de Gaulle airport was criticized for its unusual curves, yet Andreu's groundbreaking, futuristic building later was seen to distinguish de Gaulle from more generic European and international air hubs. (The same airport's Terminal 2E, also designed by Andreu, gained attention in 2004 when it collapsed, tragically killing four people.)
Beijing 's daring National Grand Theater is as much a spectacle as the productions that will be staged inside in the 2,416-seat opera house, the 2,017-seat concert hall, and the 1,040-seat theater. At night, the semi-transparent skin will give passersby a glimpse at the performance inside one of three auditoriums, a feature that highlights the building's public nature.
The Grand Canyon Skywalk
The Glass Bridge Construction of the Skywalk began March of 2004 and is estimated to be completed by 4th quarter of 2006. Glass Bridge will be suspended 4,000 feet above the Colorado River on the very edge of the Grand Canyon. On May 2005, the final test was conducted and the stucture passed engineering requirements by 400 percent, enabling it to withstand the weight of 71 fully loaded Boeing 747 airplanes (more that 71 million pounds). The bridge will be able to sustain winds in excess of 100 miles per hour from 8 different directions, as well as an 8.0 magnitude earthquake within 50 miles. More than one million pounds of steel will go into the construction of the Grand Canyon sky walk..................
