Balfour Beatty has removed the final temporary elements from the London 2012 Aquatics Centre.
The contractor used two cranes weighing a combined 1,550 tonnes to lift the final trusses that formed the spine of the temporary stands for the swimming and diving venue.
Work has started to install 3,000m² of glass along the sides of the Aquatics Centre as it is prepared for legacy mode.
Queen Elizabeth Olympic Park chief executive Dennis Hone said: “The £292M project to adapt the Park and take down the temporary venues, like the Aquatics Centre seating, is running on time and on budget.
“We will open the first part of the Park this summer with a series of events in the north of the Park and the Copper Box opening to the public.
“The rest of the Park will open in phases through to spring 2014 when the Aquatics Centre will open and people will be able to swim in those fantastic Olympic-sized pools.”
