Excavation work started on Skidmore, Owings and Merrill (SOM) skyscrapers in Beijing and Tianjin in the last week. The Beijing project, the China World Trade Center, will reach 918 feet (280 meters), while the CTF Tianjin Tower is projected to hit 1,740 feet (530 meters).
CTF Tianjin Tower will be the second tallest building in the city of Tianjin and incorporate a variety of new technologies, according to the architect. A full list of Tianjin's tallest towers can be found here.
The tower will be "significantly quieter, with less movement than other tall buildings," said SOM Structural and Civil Engineering Partner William Baker, a member of the CTBUH Board of Trustees.
According to the SOM release:
“The gently curving glass skin conceals eight sloping columns that lie behind the primary bends of the elevation. Integral to resolving gravity and lateral loads, these sloping columns increase the structure’s stiffness in response to seismic concerns. Strategically placed, multi-story wind vents combined with the aerodynamic shape of the tower dramatically reduce wind forces by reducing vortex shedding.”
The tower will house offices, 300 serviced apartments and a 350-room hotel.
The 58-story Beijing project, part of the China World Trade Center, will be located immediately northeast of the SOM-designed China World Trade Center Tower 3, completed in 2010, which is the tallest building in the Chinese capital. A full list of Beijing’s tallest towers can be found here.
The new tower’s design features horizontal bands of canted glass that wrap the building’s square floor plate.
“The form is evocative,” SOM Design Partner Brian Lee writes. “It could be a bamboo shoot or a pagoda, but it’s driven by practical issues.”
The exterior curtain wall is three degrees off vertical to make the façade self-cleaning, while the decreased glare and reflection of light results in a reduction in energy loads, SOM said in the statement.
The steel and concrete tower will include 1.32-million-square-feet (123,000-square-meters), comprising offices and a 600-room hotel.
