who designed the hsbc building in hong kong
HSBC Building (Hong Kong) The new building was designed by the British architect Norman, Lord Foster and civil & structural engineers Ove Arup & Partners with service design by J. Roger Preston & Partners, and was constructed by Wimpey International.[9] From the concept to completion, it took seven years (1978â€“1985). The building is 180 metres high with 47 storeys and four basement levels. The building has a modular design consisting of five steel modules prefabricated in the UK by Scott Lithgow Shipbuilders near Glasgow, and shipped to Hong Kong. About 30,000 tons of steel and 4,500 tons of aluminium were used.
Willis Tower The Willis Tower, built as and still commonly referred to as the Sears Tower, is a 110-story,[4] 1,450-foot (442.1 m) skyscraper in Chicago, Illinois.[3] At completion in 1973, it surpassed the World Trade Center towers in New York to become the tallest building in the world, a title it held for nearly 25 years; it remained the tallest building in the Western Hemisphere until the completion of a new building at the World Trade Center site in 2014. The building is considered a seminal achievement for its designer Fazlur Rahman Khan.[5] The Willis Tower is the second-tallest building in the United States and the Western hemisphere – and the 16th-tallest in the world. More than one million people visit its observation deck each year, making it one of Chicago's most-popular tourist destinations. The structure was renamed in 2009 by the Willis Group as part of its lease on a portion of the tower's space.
