BALFOUR BEATTY and Amec this week said they were putting together a joint bid to act as programme manager of the London 2012 Olympic Park.
They said they were also considering adding more firms to the team as their bid evolves.
Amec had been shortlisted for the programme management contract before Olympic Delivery Authority chief executive David Higgins scrapped it in favour of an expanded delivery partner role (NCE 26 January).
Amec's design and project management division has teamed up with contractor Balfour Beatty to better suit the new role.
This requires bidders to manage planning, design, construction, commissioning, maintenance, costs and conversion to legacy mode after the games.
Parsons Brinckerhoff was also putting together an expanded team.
Capita Symonds executive director Jonathan Goring said his firm would continue to bid with KBR, with Franklin & Andrews as the team's cost consultant.
It is also understood that, Bechtel is interested in making a bid even though it was not shortlisted first time around.
Other fims originally shortlisted - Arup/Gardiner & Theobald, Mace/Davis Langdon and Lend Lease Projects - were all likely to re-bid.
The deadline for tenders is 25 April 25.
