<text>  An Adelaide hospital has been named the third most expensive building in the world, putting it ahead of glitzy skyscrapers in Dubai, London and Singapore. The Royal Adelaide Hospital was named on a list of the worlds most expensive buildings compiled by building data company Emporis, beaten only by New Yorks One World Trade Centre and the Palace of Parliament in Bucharest, Romania. The revamped hospital, which is currently under construction, will cost a staggering US2.1 billion A2.7 billion compared with the One World Trade Centre which cost US3.9 billion A5.04 billion to build and the Palace of Parliament which cost US3 billion A3.9 billion. The New Royal Adelaide Hospital was named on a list of the worlds most expensive buildings . The revamped hospital, currently under construction, will cost a staggering US2.1 billion A2.7 billion The South Australian government said the State Budget would need to account for an extra 177 million in funding for the hospital in December last year . The 800-bed hospital due to open in April 2016 but an independent review has concluded the project wont be finished until the second half of that year . The top 10 was rounded out by Las Vegas resort The Palazzo and Londons The Shard, both at US1.9 billion, the Taipei 101 at US1.76 billion, Dubais Burj Khalifa the tallest building in the world at US1.5 billion, Singapores CapitaGreen at US1.5 billion, Kyoto Station at US1.25 billion and Hamburgs Elbphilharmonie at US1.03 billion. Another Adelaide building - Myer Centre was the next Australian construction on the list at number 13, costing US1 billion. The next most expensive Australian buildings were Sydneys Chifley Tower at number 16, costing US1 billion, and Sydneys ANZ Bank Centre, costing US800 billion. The list has been adjusted to take currency movements into account and considers both buildings under construction and existing buildings that were built after 1976. Construction economics expert Timothy OLeary said the Royal Adelaide Hospital would be the most expensive building ever built in South Australia. The worlds most expensive building is the One World Trade Centre in New York which cost A5.04 billion . Second on the list was Romanias Palace of Parliament which cost US3 billion A3.9 billion 1. One World Trade Center, New York City - completed in 2014 for US3.9 billion . 2. Palace of the Parliament, Bucharest - completed in 1988 US3 billion . 3. Royal Adelaide Hospital, Adelaide - completed by 2016 for US2.1 billion . 4. The Palazzo, Las Vegas - completed in 2007 US1.9 billion . 5. The Shard, London - completed in 2013 for US1.9 billion . 6. Taipei 101, Taipei - completed in 2004 for US1.76 billion . 7. Burj Khalifa, Dubai - completed in 2010 for US1.5 billion . 8. CapitaGreen, Singapore - completed in 2014 for US1.4 billion . 9. Kyoto Station, Kyoto - completed in 1997 for US1.25 billion . 10. Elbphilharmonie, Hamburg - completed by 2016 for US1.03 billion . And its the type of building that costs a lot of money its a number one hospital that will service the health needs of the state for decades to come, said Mr OLeary, from the University of South Australia. Its certainly a big deal for Adelaide because its being funded by taxpayers. Mr OLeary said it was difficult to assess costs of the project and how they would pay off in future. Theres no way to know if its value for money without comparing it to other similar projects, he said. Probably whats missing from that list is there must be other big hospital projects in the pipeline around the world that are quite expensive. The list does not seem to be comprehensive, as similarly priced hospitals such as the Gold Coast Hospital in Queensland and the Fiona Stanley Hospital in Western Australia have been omitted, as have other high profile buildings from around the world, such as the Westfield London shopping centre cost approx. 3bn, said a statement from South Australian Health. Upon completion the new Royal Adelaide Hospital will deliver state of the art care in one of the most advanced hospitals in the world, the statement said. Other recently built Australian hospitals missing from the list include the Fiona Stanley in Perth, which opened in 2014 and cost A2 billion and the Gold Coast University Hospital which opened in 2013 and cost A1.76 billion. On Wednesday the former Gold Coast University Hospital project director was appointed temporary manager of the Adelaide project after program director Andrew Nielsen stepped down. This comes after the South Australian government said the State Budget would need to account for an extra 177 million in funding in December last year. The Palazzo - a luxury resort on the casino strip in Las Vegas - was completed in 2007 and cost US1.9 billion . The Shard skyscraper in London was completed in 2013 for US1.9 billion . The 800-bed hospital due to open in April 2016 but an independent review has concluded the project wont be finished until the second half of that year. Mr OLeary said cost blowouts were to be expected on any large project. Any billion dollar construction project is an extremely complex undertaking, he said. Original estimates and budgets tend to blow out because of the complexity. Dubais Burj Khalifa is the tallest building in the world and cost US1.5 billion to build . Another Adelaide building - Myer Centre was the next Australian construction on the list at number 13 . The next most expensive Australian buildings were Sydneys Chifley Tower at number 16, costing US1 billion, and Sydneys ANZ Bank Centre pictured, costing US800 billion .
