The OECD economic agency has increased its growth forecast for the UK economy this year to 1.5% from an earlier estimate of 0.8%.
It said UK growth had gained momentum through the first half of the year.
The forecast came as a survey indicated that activity in the UK construction sector grew at its fastest pace for nearly six years in August.
On Monday, a similar survey had shown strong growth in the manufacturing sector.
