Balfour Beatty is the preferred bidder on a highways maintenance contract potentially worth around £350M.
Suffolk councillors will be recommended to award the contract to Balfour in a meeting on Tuesday 11 December. The firm has become the preferred bidder following a nine month assessment process which looked at five contractors.
The contract is due to start on 1 April 2013 and will last for at least five years with a possibility of extending to ten years. The successful bidder will be responsible for highway maintenance and improvement works, winter gritting, street lighting, traffic signals and bridge works in the county.
If approved, around 200 Suffolk County Council and Ipswich Borough Council staff will be transferref to Balfour Beatty Living Places in April 2013.
Suffolk Council spends around £35M a year on its roads.
