The Department of Health has fired the starting gun on its ProCure22 construction framework, which could be worth as much as £5bn.

The framework is due to replace the current ProCure21+ framework, which will end in September 2016.

ProCure22, which will run for a maximum of four years, is expected to have an annual value of between £650m and £750m, with its total value set to be worth between £2bn and £5bn.

It will be structured in a similar way to ProCure21+, with principal supply chain partners delivering a range of capital investment schemes.

Like its predecessor, the schemes on ProCure22 will include works for the NHS, such as clinical and specialist facilities like community hospitals and mental health facilities.

Projects under the framework can be delivered for the Department of Health, its sub-departments the NHS, NHS authorities and NHS trusts, and any other local authority health and social care-related facility in England.

The framework is intended to support operator initiatives such as investment in sustainability, carbon management, efficiency and productivity initiatives, according to OJEU documents.

The Department of Health has said that further information on lots and other contracting authorities will be provided later in the year.

Projects currently under way on the existing ProCure21+ framework include the £150m redevelopment of Luton and Dunstable University Hospital, won by Galliford Try, and a £160m design-and-build contract for a new critical treatment hospital for Hampshire Hospitals NHS Foundation Trust, won by Kier.
