Balfour Beatty has secured a £41m contract from E20 Stadium Partnership to carry out the roof reconfiguration works to the London 2012 Olympic Stadium.

As per the contract, Balfour Beatty will dismantle and remove the existing roof and floodlight towers during the first four months of the contract.

The company will construct a new cable net system on the floor of stadium and then lift it into position to support the new roof.

Balfour Beatty said a number of 600t cranes operating within the stadium will then tandem lift the supporting roof steelwork into place.

Designed by the architectural firm Populous, the redeveloped roof structure will feature an 84m gravity-stressed structure, which will provide cover for football fans sitting above the existing running track.

After completion, the roof will be twice its original size, to provide all-weather cover for spectators while offering improved acoustics for concerts.

Work in the project is due to commence later this year and is scheduled finish in early 2015.

Balfour Beatty chief executive Andrew McNaughton said building information modelling techniques will be used to develop a construction methodology to reduce the programme risk to the scheme.

"Once complete, the stadium will provide a first-class sporting and cultural facility for many generations to come," McNaughton said.

The roof contract will be transferred over to the successful bidder of the main conversion contract for the London 2012 Olympic Stadium, which is being procured under a separate contract.

Apart from the new legacy activity at the Olympic Park, Balfour Beatty will also convert the London 2012 Aquatics Centre into a facility to be used by local communities.

Balfour Beatty is removing the temporary seating stands and replacing them with elevations that reveal more of the Zaha Hadid-designed building.
