A-one+, a joint venture between Costain, Halcrow and Colas, has been awarded a two-year extension to its five-year managing agent contractor (MAC) contract, by the UK’s Highways Agency.

Estimated to be worth £60m per annum, this latest contract will extend the current contract to June 2016.

Under the contract, the JV will provide operational and routine maintenance services and deliver improvements on the motorways and trunk roads in the East Midlands (MAC Area 7).

The area covers the counties of Derbyshire, Leicestershire, Lincolnshire, Northamptonshire, Nottinghamshire and Rutland.

Costain chief executive Andrew Wyllie said that this contract extension demonstrates the successful implementation of the ‘Choosing Costain’ strategy, in which the company focuses on building long-term relationships and winning repeat work from blue chip customers who spend billions on meeting vital infrastructure needs.

"Estimated to be worth £60m per annum, this latest contract will extend the current contract to June 2016."

"This contract further contributes to the strength of our order book, which comprises approximately 90% repeat business," Wyllie said.

The Highways Agency has previously worked with A-one+ to deliver substantial savings as part of the retrofit of asset support contract conditions to existing MAC contracts.

The extension will enable the agency to develop and test new approaches to achieving greater efficiencies.
