Rising 101 storeys (509 metres) above its surrounding urban environment, Taipei 101 is currently the world's tallest building. Designed by C.Y. Lee & Partners, it opened in 2004 amid spectacular Chinese new year celebrations, and has become the international symbol of the country's economic prosperity. This book examines the technology that made it possible to complete this mega-structure, such as the world's largest tuned mass damper located on the 88th floor that stabilises the structure during the region's frequent earthquakes, and the world's fastest double-deck elevators. It includes technical information and data, chapters written by the architects and engineers who worked on the project, hundreds of colour photographs, plans and drawings.
