Ever since struck by frequent earthquake disasters, tsunamis, typhoons, fires and war destruction, Japan not only overcame those disasters but obviously used them as a reason to develop new technologies and advanced construction systems. More than 2,000 earthquakes yearly or rather 60 % of earthquakes worldwide and 30% of Tsunamis happen in Japan. As it has been proved by the March 2011 earthquake (strength: 9,0) once more, Japan has developed highly advanced earthquake resistance technologies. The fourth largest earthquake for 1,300 years moved Japan two meters to the east, tilted the axis of the Earth around ten angular degree and induced a devastating tsunami. Still, no damage occurred at the building site of the Tokyo Sky Tree although the earthquake damping system, that is described here, still was under construction. Especially buildings in the Tokyo area have to endure several hundred smaller and larger shakings per annum without letting them cause damage to structure, sub-components and technical infills. With a height of 634 meters, the Tokyo Sky Tree (Tokyo Sukai Tsuri) is the world's second largest man-made structure on earth. However, the tower is one of the safest buildings ever built. This has been enabled by a fusion of a) cutting edge structural design, b) advanced damper technology and c) robot supported construction processes. Obayashi constructed the Tokyo Sky Tree by using techniques and components of its Automated Building Construction System (ABCS) which they have been developing since the 1980s. It was designed to automate on-site assembly operations to a high degree by installing an on-site factory, with automated logistics, automated column and beam positioning, automated welding and real-time process control. As the Tokyo Sky Tree with its 643 meters height is an extreme project and requires high precision and technical support, using and adjusting the ABCS Sub-systems for this tall structure was highly efficient.
