The firm, which unveiled plans to re-scale construction two years ago, ahead of expected public spending cuts, said margins would be stronger than last year as a result.
In a trading statement covering the first six months of the year, Carillion said the group’s order book and probable orders are expected to remain strong at around £18bn.
After a programme of redundancies, the integration of Carillion Energy Services has been completed with cost savings set to meet the 2013 target of £25m.
Big construction contract wins in the first half included the £45m job to upgrade the A23 between Handscross and Warninglid, a £45m contract to reconfigure Pier 5 at Gatwick Airport, a £42m contract for Argent in Manchester and Academy Schools contracts worth over £40m.
Over the medium term, Carillion expects new opportunities to come from the UK Government’s £250bn, five-year National Infrastructure Plan, of which 70% is to be privately financed.
The contractor added that it was on course to double turnover in the Middle East and in Canada in the five-year period to 2015, in each case to around £1bn.
