The existing framework deal is due to end next September and will be replaced by ProCure 22, which could see a spend of £2bn-£5bn over four years.
Balfour Beatty, Galliford Try hps, Integrated Health Projects, Interserve, Kier and Willmott Dixon are expected to put up a strong fight to renew.
At this stage no decision has been made on how many partner contractors the new framework seeks to appoint.
The new framework will continue to address the principles of effective collaboration which led to the success of the repeatable rooms and standardised components initiative, and is already achieving big savings through set detailed design templates.
