French contracting giant Vinci said last week that it would be keen to build London's Olympic stadium on a private finance basis.
It used a similar approach when it built the Stade de France in Paris for the 1998 World Cup.
Vinci also believes it could make the stadium a productive business after the games to meet the legacy ambitions of the Olympics bid.
'If asked we would love to do it, ' said Vinci Concessions chief executive David Azema.
Vinci built Stade De France in a consortium with Bouygues in three years, just in time for the World Cup. Work began after years of delay while the French government decided on a site for the stadium.
The private sector put up 53% of the £200M cost with government providing the remainder. Vinci now owns 67% of the private sector company which will operate the stadium until 2025.
Revenue from events is shared with the French government and Stade de France is in profit.
'We have a big incentive to find new uses for the stadium, ' said Azema. Football and rugby are played there but Stade de France, with its distinctive flying saucer roof, can also be reconfigured for athletics, horse racing, motorsport and concerts.
