The final beams to complete the Zaha Hadid and Arup designed roof for the 2012 Olympic Games Aquatics Centre were installed last week.
Contractor Balfour Beatty completed installation of the aluminium and steel for the sweeping roof that is 160m long and 80m across at its widest point and weighs more than 3,000t.
The centre will have a 17,500-seat capacity during the games for swimming, diving, synchronised swimming, water polo finals and the swimming discipline of the modern pentathlon.
The roof’s frame is made from a 30m steel truss connected to 10 smaller trusses. The completed frame rests at just three points. The roof is designed to stretch, twist and contract under snow and wind loadings and in response to changing temperatures.
