SPACES
The building challenges the typical search pursuing final height of the skyscraper.
PROGRAM
The 473.000m2 building are divided as follows: 64.200m2 administration 54.900m2 multi - purposes , 65.800m2 new productions, 31.800m2 broadcasting production programs 105.400m2, 30.000m2 staff facilities, parking 61.500m2, 15.000m2 services spaces plus a hotel, a visitor center and a large theater .
CONSTRUCTION
• The building is not a traditional tower, but a loop of six horizontal and vertical sections covering 473,000 m2 of floor space, creating an irregular grid on the building's facade with an open center
• Its construction is considered a structural challenge, especially because it is in a seismic zone.
• The overhang extends perpendicular 75m west and 67m south.
• The building was constructed by joining three volumes created a unique final volume.
• In order not to block the structural differentials this connection was scheduled to take place at dawn, when the steel of the twin towers were cooled and raised and managed the same temperature.

Structural Concept
• 3 story basement, 9 story base, 2 towers, 9-13 story overhang (36 stories above ground) joined as a ‘continuous tube’
• Towers slope in 6 degrees each direction
• External diagrid solution for high seismic area as well as solution to connect full loop
