Construction of 2012 venue progresses to pouring concrete podium slab and installing terracing units

The Olympic stadium has moved into the next phase of construction, as the 40-acre site prepares for the installation of seating terraces, and the concrete slab is poured to create the podium level.

Each of the 12,000 pre-cast concrete terracing units can weigh up to 10 tonnes, and contains 20% recycled concrete. 1,300m3 of concrete has been poured to create the podium slab which will serve as the stadium’s concourse.

Construction started on site in May this year, after 33 buildings were demolished. Over 800,000 tonnes of soil has been removed – enough to fill the Albert Hall nine times over.

The ODA’s Olympic stadium project sponsor, Ian Crockford said: “The Olympic stadium has been designed to be different with the legacy ambitions driving how we construct the venue.

“To create a stadium with such a temporary element will be a design and engineering first. The team is rising to the challenge and work is progressing on the ground at an impressive rate.”

Eight tower cranes now loom over the 40-acre site – an area five times the size of the Houses of Parliament.

Once completed, the stadium roof will cover an area equivalent to three and a half football pitches.
