This year marks 10 years since the London Olympics took place, and the conclusion of a mega-project four years in the making, with construction work on the Olympic Stadium beginning in 2008.

A total of 80,000 people were involved in the construction, which transformed Stratford in east London into a 2.5 sq km Olympic Park with stadium, velodrome, Basketball Arena, Aquatics Centre, and Athletes’ Village, which was later converted into housing.

The project ended up costing £8.77bn, which more than two-thirds of the public agreed represented value for money, according to a ComRes poll in 2013. The final cost was more than three times the original budget of £2.4bn.

Among the contractors involved in the construction were:

Aquatics Centre: Balfour Beatty
Athletes’ Village: Lend Lease
Basketball Arena: CLM (consortium involving Laing O’Rourke, Mace, CH2M Hill)
Media Centre: Carillion
Olympic Stadium: Sir Robert McAlpine
Velodrome: ISG

Construction of the Aquatics Centre. With two 50m swimming pools and a 25m diving pool the construction budget swelled to triple its original £75m target, with the Zaha Hadid-designed wave-shaped roof said to have cost around £60m alone.

The Olympic velodrome cost £105m to build and was completed three months ahead of schedule, opening in February 2011. (Image: Dreamstime)
