Carillion has won BT’s £500m Project Jaguar facilities management contract, beating Amec to the five-year deal as predicted by Building.

Carillion’s team, which includes Balfour Beatty subsidiary Haden Building Management and Reliance Integrated Services, will manage and maintain 8500 of BT’s properties. The agreement includes an option to extend the contract for a further five years.

Carillion chairman Sir Neville Simms said he was delighted with the deal, the UK’s largest FM contract to date.

He said: “The innovative agreement has been made possible through the development of a strong partnership with BT, which I believe will set new standards for quality and efficiency.”

The Carillion team will split the contract into eight regional centres.

A Carillion spokesman said the firm would appoint a project director to oversee the work. The other shortlisted bidders for Project Jaguar were Bovis Lend Lease/Dalkia and Mace/Citex.
