An official announcement on the preferred bidder for the deal is expected at the end of the summer, to sign off the contract and get work underway next year.
Six schools - St Paul’s Way Community School, Bethnal Green Technology College, Raines Foundation School, Ian Mikardo High School, George Green’s Secondary School and the Wessex Centre - will be rebuilt in a first wave of projects, with a further 12 schools expected to be included in a second wave.
The French giant had been pitching against rival bid teams led by Balfour Beatty and Apollo for Tower Hamlets Borough Council’s BSF programme to rebuild or refurbish every secondary school in the borough.
Apollo’s team, which also featured Enterprise and IT firm Dell, pulled out in November last year and it has now been followed by Babcock & Brown/Balfour Beatty.
A council spokesman said that it would still be pushing to get the best deal from Bouygues.
He said: “The other bidders withdrew because vital parts of their own consortia were not able to continue in the process, meaning that they weren’t able to deliver the programme fully.
“This was not due to any problems with the Tower Hamlets BSF tender process. The council is committed to selecting a partner that is able to provide value for money.”
