The report added that 40 per cent of contractors expect these positive conditions to continue, saying they expect to have more work in a year¹s time. Only 14 per cent reported falling workload.

Alasdair Reisner, CECA director of external affairs, said: "After the challenges of recent years it is encouraging to see some real growth in workload for the UK¹s civil engineering contractors.

"We recognise that this growth has been supported by the actions of Government, which has worked with industry to unlock vital infrastructure investment projects across the country.

"However, it is essential that as the wider economy returns to growth, there is no loss of focus on the continuing need to invest in our national transport and utility networks. A booming economy does not remove the need to tackle congestion and energy security ­ in fact it makes tackling these issues even more critical."
