1.4 The PFI contract, signed with the consortium Modus Services plc, known as Modus, in May 2000, provides for a relatively basic scheme to make the building functional and fit for purpose. The project will create a modern and flexible, space-efficient, working environment, needed to provide efficient direction and support to the Armed Forces, taking advantage of up-to-date business practices and making more effective use of available space and technology. The redevelopment will allow Head Office activities to be concentrated in Main Building and the adjoining Old War Office, enabling the MOD to dispose of five of its seven existing central London sites resulting in annual operating cost savings of £18 million.
