CCTV Headquarters in China:
CCTV Tower a very versatile piece of architecture is in Beijing, China. Rem Koolhaas and Ole Scheeren of OMA were the architects in charge for the building. Complex engineering design was provided by Arup.
The CCTV Headquarters is a 234 m (768 ft), 44-storey skyscraper on East Third Ring Road, Guanghua Road in the Beijing Central Business District (CBD). The tower serves as headquarters for China Central Television (CCTV) that was formerly at the China Central Television Building located at 11 Fuxin Road some 15 km (9.3 mi) to the west. Groundbreaking took place on 1 June 2004 and the building’s facade was completed in January 2008. After the construction having been delayed as result of a fire which in February 2009 surrounded the neighboring Television Cultural Center, the Headquarters has been finally completed in May 2012.
The construction of the building is considered to be a structural challenge, especially because it is in a seismic zone. The building was built in three buildings that were joined to become one and a half buildings. In order not to lock in structural differentials this connection was scheduled in the early morning when the steel in the two towers cooled to the same temperature. The main building is not a traditional tower, but a loop of six horizontal and vertical sections covering 473,000 m2 (5,090,000 sq ft) of floor space, creating an irregular grid on the building’s facade with an open center.
The CCTV Headquarters won the 2013 Best Tall Building Worldwide from the Council on Tall Buildings and Urban Habitat.
