The project involved building new facilities for Typhoon fighter jets based at the facility.

Works included creating a new headquarters building, refurbishing nine hardened aircraft shelters and a parking area for eight aircraft, providing new floodlights, and renovating dining facilities.

In addition to the new HQ accommodating engineering/logistics facilities, new classrooms and offices, the building is also highly energy efficient with climate change resilience built in.

The design and build used the existing concrete floor of a hangar which was initially used to accommodate contractor cabins, but now forms the foundation of the car park, fire fighting water tanks and pumps.

Jim Ellistone, DIO’s project manager, said: “The facility was delivered almost a month early and significantly under budget. By any standards, this has been a superb team effort. Collaboration by all parties has been outstanding and we have had the full support of the Royal Air Force throughout.”

The project began in October 2014 and was completed 14 months ahead of schedule.

It was delivered in partnership with DIO’s Total Facilities Management Team, the RAF, Watson Burnett Architects, and MOD contractors Turners and Balfour Beatty.
