The coalition of EDAW, Foreign Office Architects, Allies and Morrison and HOK Sport will oversee the transformation of the huge plot of wasteland into the capital's Olympic Park.
The group took much of the credit for the victory back in July when London won the hotly contested competition to host the games in six years' time.
But as soon as the announcement was made, EU regulations kicked in and it was announced that the masterplanning and landscaping brief would have to go out to an OJEU notice.
At the time, the group was furious that they would have to go through a fresh bidding process, claiming that they ought to have been given the project as a reward for their hard work.
But this row is now in the past. The four practices - who are understood to be working with Atkins as engineers - have seen off rival bids from the likes of Foster and Partners and Lovejoy to take on the project.
A formal announcement is expected on the winning bid next Tuesday (17 January).
