 London 2012 Olympic Games Progress Report

Testing of the London 2012 Aquatics Centre dive pool and two 50 m swimming pools that will host record-breaking performances in 2012 and open to the public after the Games have recently taken place. London 2012 Aquatics Centre on track

Once the steel is in position, cladding will start on the curving timber ceiling and work is continuing on the huge 250 m and 45 m-wide land bridge that forms the main walking access into the Olympic Park and the roof of the training pool.Testing of the London 2012 Aquatics Centre dive pool and two 50 m swimming pools that will host record-breaking performances in 2012 and open to the public after the Games have recently taken place.

The three concrete pools were tested with over 10 million litres of water before being sealed and lined with 180,000 tiles.

Work is also underway lining the unique 160 m-long wave-shaped steel roof, which weighs more than 3,000 t and is support by just three concrete columns.

Once the steel is in position, cladding will start on the curving timber ceiling and work is continuing on the huge 250 m and 45 m-wide land bridge that forms the main walking access into the Olympic Park and the roof of the training pool.

The Aquatics Centre is on track to be complete in summer 2011 ready for test events and after the Games will provide two 50 m swimming pools with moveable floors and separation booms, a diving pool and dry diving area for the full range of community and professional uses.

Capacity during the games will be 17,500, reducing to a maximum of 2,500 for the future, with the ability to add 1,000 for major events. The pool complex is located on a 50,000 m² site which required demolition of 11 industrial building before ground works could commence.

This involved excavating 160,000 tonnes of soil on what was one of the more challenging and complex areas of the Olympic Park, contaminated with pollutants including petrol, oil, tar, solvents and heavy metals such as arsenic and lead. In addition, 140,000 tonnes of clean soil was brought from other areas of the Olympic Park. During excavations, the contractors came across four skeletons which, on investigation proved to be from a prehistoric settlement.

The sweeping roof, which is 160 m long and 80 m at its widest point, is an innovative steel structure weighing more than 3,000 tonnes with a striking and robust aluminium covering, 50% of which is recycled.

Balfour Beatty is the contractors for building the Aquatics Centre and huge land-bridge that forms the roof of the training pool and the main pedestrian access to the Olympic Park.

Construction work will be complete in 2011 for test events ahead of the Games. The sweeping roof, which is 160 m long and 80 m at its widest point, is an innovative steel structure weighing more than 3,000 tonnes with a striking and robust aluminium covering, 50% of which is recycled.

As part of the landscaping and regeneration works, the river that runs alongside the venue has been widened by 8 m by construction 550 m of new river walls.

Construction started on the foundations in July 2008. A 3,000 t concrete ‘bridge’ has been built spanning and protecting the tunnels which have been dug to run powerlines beneath the site. The 18.5 m-tall northwest roof support has been built on top of this base. Work is now underway on the 250 m and 45 m-wide land bridge that forms the main ‘Gateway to the Games’ from the Stratford City development, spanning the Aquatics Centre and forming the roof of the training pool.

Around 1,000 m³ of concrete has been poured to create five sets of bridge supports, steel beams were then lifted into position to form the first section of the bridge spanning railway lines and roadways. Work is now currently underway on the section of bridge that will form the training pool roof.
