The new framework forms part of the wider umbrella Southern Construction Framework, which aims to draw together a panel of contractors covering public works in the south of England.
The largest of the three panels is the London lot, estimated to be worth up to £1.6bn over four years on past spending records.

Local authority backers expect to call upon the firms to bid for mainly education projects.
Although buildings for the emergency services, health services, civic offices and housing are also within its scope.
The framework has been designed to dovetail with the London construction programme major works frameworks agreement, which covers smaller projects.
An announcement also covering the remaining south east and southern lots is expected shortly.
