The bidding process for the contract to convert London’s Olympic Stadium following the 2012 Games has been extended, following problems with the original invitation to tender.
The London Legacy Development Corporation said that a number of companies may have been deterred from bidding for the contract due to the issues.
It said that the competition process, which closed in March, would be reopened for a further eight weeks from this week.
London Legacy Development Corporation chief executive Andrew Altman, said: “We have been very encouraged by the quality of the bids so far.
“However, a number of issues have arisen during the process and we believe it is sensible to give everyone more time so they can be addressed.”
A spokeswoman for LLDC said that although it had received 16 expressions of interest, only four formal bids had been received.
She said that some of the interested parties may have been deterred by issues relating to governing body approvals, technical improvements to the stadium and the opportunity to bid for the right to exploit the Stadium naming rights.
Altman said that it remained the intention to sign construction contracts at the end of October, with the aim of reopening in 2014.
