The construction of the London 2012 Olympic Stadium’s external structure was completed last week as the Olympic Delivery Authority (ODA) published its Annual Report and Accounts for 2008 – 2009, alongside expenses for the ODA Board and Directors.

The roof structure, which will support the fabric roof, and the black steel rakers, which act as the terracing supports for the upper tier 55,000 seats, have been completed to form the outer shell of the Olympic Stadium.The first of the 15m high, 85-tonne steel sections of the roof was lifted into place at the end of January this year, and now all 28 sections are in place over a month earlier than originally planned.
