Construction of the London 2012 Aquatics Centre is on track to start this summer after being granted planning permission.

The construction of the Olympic Village is due to start this summer, following the clearance of the area that will link the Village and VeloPark during the Games.

The Olympic Delivery Authority has awarded the contract to build the Velodrome for the 2012 Olympics to ISG InteriorExterior.

Billions of naturally occurring micro-organisms are helping clean nearly 50,000 tonnes of soil on the site of the Olympic Park so that it can be reused to create the largest new urban park in Europe for 150 years.
