A team from Birmingham law firm Wragge & Co has completed a £1.15 billion PFI deal for the Ministry of Defence.
The 25-year contract between the MoD and East-bury Park is for the redevelopment, management and operation of facilities at the Northwood Headquarters site.
Under the agreement, the 43-acre site - home to the Chief of Joint Operations - will be upgraded with new and refurbished offices and accommodation over a five-year period.
PFI associate Tony Cheema led the Wragge & Co team, working alongside partner Michael Whitehouse and John Quigley, director of North-wood Development and Change Programme.
The team comprised Mark Cooper and construction specialist Maxine Symington. Human resources experts Patrick Brodie, Kelly Chapman and Paul Carberry provided additional advice.
Mr Quigley said: "This was a large, complex scheme requiring expertise from a number of disciplines. Wragge & Co specialists worked together, understanding our objectives and providing a commercial approach backed up by industry experience. With these experts operating from Birmingham and London as appropriate, we had advisers on our doorstep when we needed them."
Tony Cheema added: "The MoD team were highly organised and very knowledgeable about continuous operational requirements and priorities.
"Northwood serves a number of functions, including both MoD Tri-Service and NATO command centres, making the site a very complex one to renew, manage and operate. The combination of the MoD team and Wragge & Co's contribution helped to achieve an excellent solution."
Wragge & Co has an ongoing relationship with the MoD and in 2005 was re-appointed to its panel of preferred legal advisers.
It is currently advising the MoD on its flagship project for the Royal Navy - the £3 billion plus project to design, build and maintain two new aircraft carriers. Other defence work this year has included acting for Lex Defence on a £110 million transport deal as part of the £8 billion AllenbyConnaught project.
