The firms have been selected by London Borough of Newham to join house builder Countryside Properties on the delivery body after a place became available when Lend Lease decided pull out last year.
While Bouygues is a complete newcomer to the framework, the team that Laing O’Rourke features in is a revised version of a consortium that had previously been on the panel.
E-Central sees First Base, Chelsfield Partners and East Thames Group as new partners for Laing O’Rourke.
The earlier version of the consortium had seen the Dartford contractor link up with house builders Crest Nicholson and George Wimpey; housing associations Genesis and Family Mosaic and property firm Development Securities.
The panel was first set up in October 2005 to undertake the phased regeneration of the area including building of 8,000 homes and the creation of 500,000 square metres of floor space in a new town centre.
Coutryside Properties has started work on the first phase around Fife Road, with designs in development for the redevelopment of Rathbone Market ahead of a planning submission later this year.
Work on further phases of the masterplan will be tendered by the panel members. Developer Modus has been selected as a reserve bidder should any further panel members drop out.
