The association’s third generation framework sees the number of preferred firms dropped by around a third from 31 to 23 this time around.
Previous winners Allenbuild, Bafour Beatty (Mansell), Graham, Lakehouse, Osborne and Sisk are not joining the fresh line-up.
While a spread of big name contractors from Ardmore and Bougyues to Wates and Willmott Dixon Partnerships are re-signed to deliver its ambitious development programme.
Over the next four years the housing association is believed to be set to spend up to £1.25bn.
The new Constructor Framework for Development Programme deal is billed as having a total value of up to £10.8bn over four years as it is potentially open to all London housing associations.
