  8. 8. 07 DesignNews Too Big To Fail? : Long awaited and much debated, the enormous headquarters for CCTV finally opens, already a symbol of the new Beijing. But what does it actually say about architecture and China today? P romising to “kill the skyscraper,” Rem Koolhaas and his colleagues at Office for Metropolitan Architecture (OMA) grabbed international attention in 2002 when they won the competition to design a huge headquarters in Beijing for China Central Television (CCTV), the state-run news and entertainment network. Polemical and hyperbolic as usual, Koolhaas said the skyscraper had become “corrupted” by its proliferation around the world and “negated by repetitive banality.” So instead of joining the race to build ever taller, his scheme bent the high-rise into a loop of interconnected activities. Four years after it was originally scheduled to open—in time for the network to broadcast the Beijing Olympics from its new home—CCTV isCCTV Headquarters finally moving employees into the controversial building, a 5.1 million-square-foot structure that even before it was completed had imprinted its swaggering form on the fabric of the city and theOffice for Metropolitan Architecture | Beijing, China mental map of its citizens. The building shares a 45-acre site with a low-rise, ring-shaped service structure and a 31-story tower called the Television Cultural Center (TVCC), both of which OMA also designed.By Clifford A. Pearson on Acrhitectural Record
  9. 9. 08DesignNews That form derived from OMA’s program- driven approach to design. “We presented the building as a diagram of all the companys components and made the argument that it was important that they confront each other,” says Koolhaas. Earlier, OMA had worked for Universal Studios on a headquarters in Los Angeles and learned that media companies often suffer from being fragmented. So the firm connected CCTV’s operations—including broadcasting, production, and administration— along a circulation loop that moved from the The service building provides power to the building’s base up a sloping tower, across a entire complex and houses security personnel, right-angled bridge (called the overhang), and while TVCC will have a Mandarin Oriental down a second sloping tower.

It people, reports Koolhaas. is being repaired and should be complete in 2013. The site anchors a new central business district emerging from an industrial area built during the Mao era. Plans call for about 300 high-rises there, which is one reason why “The form of our building OMA took a different approach with CCTV. According to Koolhaas, three of the four other was attractive to the client,” firms competing for the job (KPF, SOM, and says Koolhaas. Dominique Perrault) proposed skyscrapers, while only Toyo Ito offered something different “It set us apart.” (a disc-shaped structure with a small tower). “The form of our building was attractive to the client,” says Koolhaas. “It set us apart.”
  10. 10. 09 DesignNewsThe OMA team was led by Koolhaas, OleScheeren (a partner until he left the firm in 2010),partner David Gianotten, and project managerDongmei Yao. The firm worked closely with EastChina Architectural Design & Research Institute,which provided both architecture and engineeringinput.From the beginning of the design process, OMAcollaborated with Cecil Balmond and a teamof engineers at Arup. To resist the huge forcesgenerated by two towers—each sloping sixdegrees in two directions—as well as significantpotential seismic and wind events, Arup deviseda scheme that turns the entire exterior into acontinuous structural tube. This system is formedby a web of diagonal steel braces that expressesthe pattern of forces acting on the building and are less intense, the web is looser. As a result, the in big Chinese cities look dirty almostserves as an important visual element on all of exterior surfaces read as a kind of engineering immediately, but CCTV’s glazing handles thethe facades.

Arup and OMA had considered canting it hard to grasp the building’s scale. In certain these elements as well, but the cost of angled light and at certain distances, the 768-foot-tall elevators made it unfeasible. In addition to the structure seems almost to disappear.
