Key highlights of the forecast include:
- Construction output will grow 4.8% in 2014 and 5.3% in 2015
- Private housing starts are expected to grow 18.0% in 2014 and 10.0% in 2015
- The private commercial sector is set to increase 3.7% in 2014 and 6.1% in 2015
- Roads construction will rise 46.1% by 2018
- Energy infrastructure is anticipated to grow 118.2% by 2018
Dr Noble Francis, Economics Director of the Association, said: “Our Forecasts reflect a welcome, recurring theme as growth continues and begins to broaden.
“Short-term activity is still led by private housing, infrastructure and commercial, and areas of public sector construction are showing the first signs of increasing strength.
“We believe the expansion will continue through 2018.
“Recovery is not a foregone conclusion however, and several important risks remain, primarily around the strength of the UK and Eurozone economies, the policy outcomes following the 2015 General Election and the impact of any supply constraints such as the scarcity of labour and materials.
Francis added: “We forecast private housing growth will moderate in the longer term to 5.0% per year from 2016.
“Commercial, the largest sector, is expected to benefit from a pickup in consumer spending and business investment and drive growth in each year up to 2018.
“Output in the sector is forecast to reach £26.8 billion in 2018, but this remains 16.6% lower than the pre-recession peak in 2008.
“Offices is one sub-sector of commercial where demand is intensifying in regions beyond London and the South East.
“Given this, the Association expects new offices construction will expand by 10.0% in 2014 and 8.0% in 2015, followed by 7.0% in 2016.
“Other commercial sub-sectors also show signs of strength.
“The retail sub-sector remains exposed to the long-term trend away from the high street to internet shopping, and previous peak output levels are unlikely before 2018, but new, large developments should still support growth of 8.0% from 2015.
“Infrastructure output is forecast to rise by 8.2% per year, on average, over the next four years.
“Roads construction is forecast to increase by 10.0% in 2014 and a further 5.0% in 2015 due to growth in the Highways Agency’s capital funding.
“Rail output is forecast to rise 8.0% in 2014 and 2015, but from 2016, growth is anticipated to slow, reflecting uncertainty regarding funding.
“The energy sub-sector is forecast to grow 10.0% in 2015 before work on Round 3 Offshore wind and Hinkley Point C leads to growth rates of 15.0% in 2016 and 2017 followed by 25.0% growth in 2018.
“Finally, austerity in the previous three years has meant that public sector construction has severely hindered overall construction recovery.
“In 2013/14, however, we saw the nadir of capital investment falls and consequent rises in funding for schools and hospitals are expected to lead to public sector construction growth averaging 2.6% per year between 2015 and 2018.”
Francis concluded: “The Association’s central forecast estimates that construction output will rise 4.8% in 2014, a marginal change from the previous 4.7% estimate.
“Output is forecast to rise a further 5.3% in 2015, an upward revision from 4.8% growth in the Association’s Summer Forecast due to the continued strength of the UK economy.”
