The SW and SE capital works framework contracts cover a diverse range of military airfields, naval bases and military establishments across the south of England from Cornwall to Kent and as far north as Gloucestershire and Oxfordshire, including the London area.

MoD’s estate procurement arm DIO is now inviting firms to seek a shortlist place for the Next Generation Estate Contracts covering projects worth up to £12m.

It is expected that the framework contracts will be awarded by summer 2015 to a pool of five contractors in each, which will then bid for jobs in mini competitions.

Deals will run for four years, with an option to extend up to a further three years.

Potential framework contractors will need to show a minimum turnover of £18m along with recent experience of project managing construction projects worth more than £5m.

Sub-contractors that do not meet these thresholds may have an opportunity to support the potential framework contractors.

John Jones, Frameworks projects manager, said: “DIO is pleased to welcome Interest from both large and small businesses in these two regional capital works framework contracts in the south of England.

“Bidders will be required to deliver a complex and diverse range of facilities for the Defence estate.

“In addition, the Framework contracts will also be used to procure a significant proportion of work in support of military rebasing up to 2020.”

DIO sought initial expressions of interest in these particular contracts in 2011, along with another four UK regional frameworks.

But the process was put on hold to await further detail on military rebasing plans emerging from the Strategic Defence and Security Review.

The framework contracts will operate in parallel to the National Capital Works Framework contract for higher value and more complex projects worth up to £50m.
