US engineering specialist, Amec and Balfour will bid for the delivery partner contract as the G3 partnership.

US engineering specialist Jacobs has joined Amec and Balfour Beatty to bid for the delivery partner contract for the Olympic games.

The move, announced today, comes after speculation that Amec and Balfour Beatty were looking for a third partner to bid for the role. The partnership, named G3, will compete with a host of other alliances for the role, including KBR/Capita/Bovis Lend Lease and Parsons Brinckerhoff/EC Harris/Taylor Woodrow/Sinclair Knight Merz.

Balfour Beatty chief executive Ian Tyler said: "G3 brings together the best programme management skills and an exceptional record of achievement in delivering the most complex projects. This, backed by the partners' financial strength, creates the best team to fulfil this demanding role."

The G3 bid team is being led by Rod Hoare, who led Metronet's successful bid for the London tube PPP awarded in 2003 and was responsible for the creation of the Heathrow Express.

The contract will be awarded this summer, with the successful bidder taking responsibility for the management of the design and delivery of the Olympic infrastructure. Other firms expected to submit a bid before the April 25 deadline include engineering giant Bechtel.
