Carillion said it has won the Network Rail contract to work on the electrification of the north-west rail project.
The infrastructure group told investors it has signed contracts, secured preferred bidder positions and been awarded frameworks worth £1.7bn since June 30.
These include the Midland Main Line electrification project, which was recently “unpaused” by the Government, the Northwest Electrification project and the electrification of the Schotts line in Scotland.
Chief executive Richard Howson said: “As we expected, the pace of work winning in the second half of the year has started to pick up.
Since the half year, we have secured contracts, preferred bidder positions and framework agreements that are expected to be worth around £1.7bn.
“With cash flow remaining healthy and these recent contract successes, we remain confident of achieving this year’s targets, including ending the year with strong revenue visibility for 2016.”
