The London Olympics infrastructure has been built in the most sustainable way possible.
Here are some facts that helped the organising committee achieve their objectives:
Work is well underway to create around 250 acres of new parklands, on former industrial land, that will provide a colourful and festival atmosphere for the London 2012 Games and afterwards become the largest new urban park in the UK for over 100 years.
The first of 4,000 new semi-mature trees are taking root in the Olympic Park and Olympic Village, in what is thought will be the largest one-off planting of its kind in the capital.
New habitats for species including: otter; kingfisher; grey heron; bee; house sparrow; bat; song thrush; starling; toadflax brocade moth; lizard; black redstart; flower and fungus beetle; frogs, newts and toads; eel; water vole; slow worm; grass snake; linnet; sand martin; swift; and invertebrates.
Five soil-washing machines have successfully completed cleaning most of the one million cubic metres of soil contaminated with oil, petrol, tar, cyanide, arsenic and lead.
More than 220 buildings demolished with 98 per cent of the materials by weight recycled, well over the 90 per cent target.
Over 5km of riverbanks replaced or refurbished and 30,000 tonnes of silt, gravel and other materials dredged from the rivers.
The Velodome has a 6,000 capacity in Games-time and Legacy – 3,500 around the track and 2,500 in upper tiers suspended within the curves of the roof.
Curved steel structure made up of more than 2,500 sections of steelwork. Shape is designed to reflect the geometry of the cycling track, rising in height by 12m from shallowest point to the highest.
At 30kg/m2, roof weighs roughly half that of any other covered Velodrome.
