A joint venture set up by Wolverhampton- based construction group Carillion and service firm Enterprise has landed a Ministry of Defence deal worth more than £500 million.

CarillionEnterprise will be responsible for maintenance, new build and refurbishment of around 8,500 buildings and other infrastructure throughout the Midlands, the North of England and Wales over a seven-year period, with the potential for a three- year extension.

Tony Harden, CarillionEnterprise managing director, said: "We are delighted to have been selected for this major defence services contract.

" The heart of our approach is to introduce innovative ways of working that will enable the Ministry of Defence to maximise value for money through improved efficiency and the delivery of leading- edge supply chain management."

Mark Grant, RPC integrated project team leader at Defence Estates, said: " The successful completion of negotiations is a tribute to the effective collaborative approach between Defence Estates and CarillionEnterprise.

"Defence Estates is confident that an effective service delivery system has been put in place - one that will deliver better value for money and greater efficiencies to its customers."
