The consortium funding the project is composed of more than 36 international companies, mainly banking corporations, insurance companies and developers from Japan.
Changes to the design resulted in extra costs of more than US$ 200 million due to the design refinements, including structural system re-design, foundation re-design and increased safety features, made as a consequence of September 11th 2001.
The foundation stone was laid on August 27, 1997, but a fund shortage on the Japanese side caused by Asian financial crisis halted the project, and nothing had since been done to the projected structure.
The tallest building in the People's Republic of China, replacing Jin Mao Tower.
The design of the opening near the top of the tower changed in mid-October 2005 during the course of construction, from a circular to a rectangular opening. Architect and developer claim that it is cheaper and easier to implement the new design.
Glass and metal were covered on simple geometric bodies to create mysterious sight effects.
Construction finally resumed on February 13th, 2003.
A 6-star hotel will be located near the top of the building, which will be the second highest hotel in the world after the one in International Commerce Centre.
Not implemented within two years, the project should have been canceled according to relevant regulations. However, because it is a project of huge investment and there have been no other suitable investors, the building remained, and in four years would finally rise up in Shanghai.
Due to the design change of the top opening from a circle to a trapezoid, the tram-car system that would travel vertically inside the big circle is cancelled.
Located near the Jin Mao Tower in the financial district of Shanghai.
The maximum elevator speed is 600 m/min.
The circular aperture at the top of the original design represented heaven, and would have served to reduce wind load on the building.
A widespread rumor in the world news media said the tower will surpass Taipei 101 as the world's tallest building at completion, but is not true.
The Consortium invested more than US$850 million for the project.
The height of this building has changed from its original plan - 94 stories at 460m to the current plan - 101 stories at 492m.
