London 2012: Aquatics Centre roof lift

Work is under way lifting the 2800-tonne wave-shaped roof of the Zaha Hadid designed London 2012 Aquatics Centre. The lift is considered one of the most complex engineering and construction challenges of the Olympic Park big build. When complete the 160 m long column-free and up to 90 m wide roof will rest on two concrete supports at the northern end and a 28 m long and 5 m wide, supporting wall at its southern end.
