- The CCTV headquarters aims at an alternative to the exhausted typology of the skyscraper.
- It is situated in a 10 hectare of land has 51 floor, 234 m height and has 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 construction of the building is considered to be a structural challenge, especially because it is in a seismic zone.
- It has two L-shaped tower lean at an angle of 60° and kink at right angles at the top.
- Cantilever overhang starts after 36 floors and is 13 floors high.
- The tower cantilevered 75m outward.
- The basic geometry consists Mobius Strip, Cantilever Overhang, Diagonal Grid and L- Shape.
- To build this building lots of construction challenges had faced by the team such as alot of steel used so weight problem, every building encounters vertical and lateral load, temperature changes so material deformation, pore water present in great amount so settelment problem.
- Diagrid System, Butterfly Plates, Piled Raft Foundation, Load Transfer Trusses all deemed good solutions.
- There are three main core accommodating 75 elevators.
- Cores remain vertical despite tower slope (shifted against floor plates).
- One core dedicated to Grandness(Administration) and other to Newness (News and Technology).
- CCTV accommodating TV studios, offices, broadcasting and production facilities.
