Shanghai Tower – the Pinnacle of Shanghai

Shanghai Tower

Shanghai Tower

The Shanghai Tower (Chinese: 上海中心) is a super tall skyscraper under construction in the Pudong District of Shanghai. Upon completion, the building will rise approximately 632 m, have 128 stories, and contain an area of 380,000 sq meters.  It will be the tallest building in China (including Hong Kong), and one of the tallest in the world (2nd tallest only behind the Burj Dubai as of today.)

Planning models for the Lujiazui financial district dating back to 1993 show plans for three supertall skyscrapers all next to each other. Two have already been built; the Jin Mao Tower (the one in the center and rear of the photo) was completed in 1998, and the Shanghai World Financial Center (the one on the right of the photo) in 2008.

The tower will be organized as nine cylindrical buildings stacked atop each other, enclosed by the glass façade’s inner layer. Between that and the outer layer, which twists as it rises, nine indoor gardens at different levels will provide public space for Shanghai residents. Both layers of the façade will be transparent, and spaces will be provided at the tower’s base. The tower will feature the world’s highest non-enclosed observation deck. The design of the glass façade is described to be able to reduce wind loads on the building by 24%, meaning less construction materials are needed, and the twisting feature will collect rainwater to be used for the tower’s air conditioning and heating systems. Wind turbines will generate power for the building. It will be the first super-tall (300 meters or taller) double-skin building in the world, acting much like a “thermos bottle,”  to insulate it and save energy. The building was originally planned to be completed by 2010, in time for the 2010 World Expo, but is now expected to be finished by 2014.

Jin Mao Tower – Housing the Highest Hotel on Earth

Jin Mao Tower

Jin Mao Tower

The Jin Mao Tower is a 1998 completed, 530 million 1998 US dollar, 88-story, 421 m landmark skyscraper in Shanghai, China. It contains offices and the Shanghai Grand Hyatt hotel. Currently it is the 2nd tallest skyscraper in Shanghai and 8th tallest in the world.

Its postmodern form, whose complexity rises as it ascends, draws on traditional Chinese architecture such as the tiered pagoda, gently stepping back to create a rhythmic pattern as it rises. The building’s proportions revolve around the number 8, associated with prosperity in Chinese culture. The 88 floors are divided into 16 segments, each of which is 1/8th shorter than the 16-story base. The tower is built around an octagon-shaped concrete shear wall core surrounded by 8 exterior composite super columns and 8 exterior steel columns. Three sets of 8 two-story high outrigger trusses connect the columns to the core at six of the floors to provide additional support.

The building employs an advanced structural engineering system of wind and earthquake engineering which fortify it against typhoon winds of up to 200 km/h and earthquakes of up to 7 on the Richter scale. The steel shafts have shear joints that act as shock absorbers to cushion the lateral forces imposed by winds and quakes, and the swimming pool on the 57th floor is said to act as a passive damper. Official dedication was August 28, 1998, a date also chosen with the number 8 in mind.

At the base, there is a 6-story podium which houses the Hyatt’s conference and banquet facilities as well as a shopping mall, restaurants, and nightclubs. The building’s anchor tenant is the five-star, 555-room Shanghai Grand Hyatt hotel which occupies floors 53 to 87. It is the highest hotel in the world in terms of distance from the ground; however the tallest building to be used exclusively as a hotel is the Burj Al Arab in Dubai (excluding the taller Ryugyong Hotel in North Korea which was never fully completed and in use). Additionally, the world’s longest laundry chute runs down the full length of the tower to the basement, and incorporates buffers to slow down the laundry during its descent.

The 88th floor (not part of the hotel) houses the Skywalk, a 1,520 m2 indoor observation deck. In addition to the panoramic views of Shanghai, it offers a topside view of the hotel atrium below. Access is through two express elevators from the basement that travel at 9.1m/s and take 45 seconds to reach the top.

Shanghai World Financial Center

The Shanghai World Financial Center is a mixed-use, 2008 completed, 1.2 billion US dollar, 101 floor, 492 m skyscraper in Shanghai, China. It became the second tallest building in the world at its completion; as well as the tallest structure in China, including Hong Kong. It is currently the world’s tallest completed skyscraper by roof, by highest occupied floor, and contains the world’s highest public observation deck at 474 m (even the all record-crushing under construction Burj Dubai will not take this last record from this skyscraper.) Shanghai World Financial Center was named on November 21, 2008, by architects as the best skyscraper completed in 2008.
