Dr Noble Francis, economics director at the CPA, said: "Continuing the trend since recovery emerged in mid-2013, growth in output was led by the private housing sector, in which 43 per cent of firms, on balance, reported a rise in output.
Increased output was also reported in private commercial, the largest construction sector, where 18 per cent of firms, on balance, reported rising volumes of offices and retail work.
Contractors reported a decline in repair and maintenance work in Q2, reflecting a drop-off in measures installed under government schemes to boost energy efficiency in recent months.
"Of lingering concern," Dr Francis
concluded, "nine quarters of rising construction activity and expectations of higher workloads over the coming year raise the issue of whether the supply of skilled labour will meet demand.
