The topping-out ceremony for Gensler’s Shanghai Tower, the second tallest building in the world, took place on Saturday in Shanghai, China.
Measuring up to 632 metres high, the tower has now reached its full height and comes second to Dubai’s Burj Khalifa which measures up to 828 metres.
The ceremony was held at the construction site in the Lujiazui development zone in Shanghai and was attended by Gensler’s founder Art Gensler as well as senior figures from the Chinese government.
As a result of wind-tunnel tests, the tower employs a twisting form, designed to reduce wind load by 24% during typhoons.
The 121- storey building is divided into nine vertical zones with hotels, cultural facilities and observation decks at the top and retail at the bottom. The in-between zones are set to contain offices.
Due to open to the public by 2014, the Shanghai Tower looms over its neighbouring towers including the 421 metre Jin Mao Tower by SOM and the 492 metre-high World Financial Centre by Kohn Pedersen Fox.
Last year, according to a research done by the Council for Tall Buildings and Urban Habitats, nine out of twenty tall buildings under construction in the world were located in China.
