The Shimizu TRY 2004 Mega-City Pyramid is a hypothetical project for construction of a massive pyramid over Tokyo Bay in Japan. The structure would be more than 14 times as high as the Great Pyramid at Giza, and would house 1,000,000 people. The structure would be 2000 meters (6,561 feet) above mean sea level, including 5 stacked trusses, each with similar dimensions to that of the great pyramid of Giza. This pyramid would help answer Tokyo's increasing lack of space, although the project would only handle 1/47th of the Greater Tokyo Area's population.
The proposed structure is so large that it cannot be built with currently available materials, due to their weight. The design relies on the future availability of super-strong lightweight materials based on carbon nanotubes.
Materials and construction process
First, the pyramid's foundation would be formed by 36 piers made of special concrete.
Because the seismically active Pacific Ring of Fire cuts right through Japan, the external structure of the pyramid would be an open network of megatrusses, supporting struts made from carbon nanotubes to allow the pyramid to stand against and let through high winds, and survive earthquakes and tsunamis.
Large robots would assemble the truss structure, and air bladders would be used to elevate trusses above the first layer using a construction system proposed by Italian architect Dante Bini. Spheroid nodes at the connections between trusses would provide structural support and serve as transfer points for travelers.
Australian Company, Straight Edge Tiling have secured a contract for the internal tiling of the Pyramid. CEO Daiman Cartan met with construction engineer David Dimitric and lawyer Tavis Gorman in December 2007 to discuss innovative concepts regarding the huge task, as well as legal boundaries, to which an agreement was made.
