Location: Olympic Park,

Stratford, London

Some of the steel trusses of the roof are 40 meters long and weigh 70 tones. Spanning from north to south, they cover the generously sized main area without any in-between supports.

Just two slim concrete supports and a concrete wall located opposite these at the southern end suffice to conduct the forces of the hidden steel-space framework construction into the ground.

As much as 2,800 tonnes of steel were needed to give the 160-metre-long and 80-metre-wide roof its light and floating look.

With a capacity of 17 500, the Aquatics Centre’s spectacular wave-like roof is 160m long and up to 80m wide – giving it a longer single span than Heathrow Terminal 5.

The venue’s roof proved to be one of the most complex engineering challenges of the Olympic Park's big structures.

This steel framework was initially constructed on temporary supports, before the entire 3 000-ton structure was lifted up in a single movement and successfullyplaced back down on to its permanent concrete supports.

The large steel roof structure is only supportedat three points and spans the column-free space for the venues’ two swimming pools

• A series of long span trusses forms the roof. They were erected in a fan arrangement to create the plan

geometry of the structure.

• The middle truss has a span of approximately 120m to a primary truss, which in turn spans 54m in a

transverse direction between two concrete cores.

• These center fan trusses cantilever beyond the primary truss to form a 30m overhanging canopy at the northern end.

The steel fan trusses of the roof are supported by a concrete wall to the south and two concrete cores to the north.
