The Defence Infrastructure Organisation this morning announced the award of £1.1bn worth of deals.

This included its national housing prime and Scotland and Northern Ireland prime contracts, which were secured by the joint venture partners.

An Interserve subsidiary, Landmarc Support Services, also picked up a big win for the national training estate prime deal worth £322m.

Both the training estate and Scotland and Northern Ireland primes are due to be in service by November 2014.

The national housing prime will be implemented through a phased mobilisation programme by December 2014.

The three contracts have been awarded on a five-year year basis with the option to extend up to an extra five years.

The contracts provide planned and reactive maintenance including grounds maintenance. The scope also includes additional professional services, low value capital works and capital projects up to £3.93m.

DIO also said it would announce winners for a further three further regional prime contracts for the Central, South East and South West of England next month.

Matt Foley, DIO Head of Future Procurement said: “Over the last 10 years, DIO has rationalised our contracting arrangements from over 250 to six manageable NGEC Prime contracts in 2014.

“These are designed to deliver value for money for Defence and the tax payer through a coherent set of firm priced contracts, which further improves financial stability.”

In line with MOD’s continuing commitment to providing decent accommodation for military personnel, the national housing prime covers more than 49,000 military homes across the country.

The new contract replaces a number of different, existing contractual arrangements to support Service Families Accommodation.

This contract has greater scope than previous maintenance contracts, as it provides additional services for managing move-in, move-out services, housing allocations and the installation of furniture and fittings.

Interserve will deliver a range of technical support, maintenance and repair service and soft facilities management, including catering and a training range booking service.

The NTEP contract will manage over 190,000 hectares of UK training estate, used by up to 30,000 Defence personnel each day.

The Scotland and Northern Ireland prime contract replaces the current regional prime contact for Scotland and two contracts delivering routine maintenance work in Northern Ireland.

Under this contract, the Amey Carillion JV will provide a wide range of hard facilities and asset management services across 30 key sites including RAF Lossiemouth, RAF Leuchars, Kinloss Barracks, HMS Caledonia and Kentigern House in Scotland, and Aldergrove Airfield, Thiepval Barracks and Kinnegar Logistics Base in Northern Ireland, together with the provision of new buildings.
