Northern Ireland Construction Bulletin - Q2 2011

The Northern Ireland Statistics and Research Agency (NISRA) today published the latest edition of the Northern Ireland Construction Bulletin.
Wednesday, 19 October 2011

The Construction Output Statistics published in the Northern Ireland Construction Bulletin provide a general measure of change in real terms in the output of the Construction Industry in Northern Ireland. The Construction bulletin can be accessed via the NISRA website.

The results are primarily used by National Accounts in the calculation of the output measure of UK Gross Domestic Product. The results are also used by Northern Ireland Government Departments, Economists, Construction Industry Analysts and Academics to understand the state of the construction sector in Northern Ireland and the wider Northern Ireland economy.

Key Findings:

  • The total volume of construction output in Northern Ireland in Q2 2011 fell by 7.0% compared to Q1 2011 and was 14.4% lower compared to 12 months ago. This is the largest quarterly decrease in the volume of construction output since Q3 2008. The volume of overall Construction Output in Northern Ireland has now fallen for 12 consecutive quarters and is 38.2% lower than the peak in Q1 2007.
  • The overall decrease in construction output was largely accounted for by a decrease in the volume of New Work which decreased by 10.8% over the quarter. This was offset by a rise in the volume of construction work classified as Repair and Maintenance which increased by 2.4% over the quarter.
  • The volume of New Work has now fallen for six consecutive quarters and is 47.1% lower than the peak in Q1 2007.
  • All sub-categories of Construction Output (Housing, Infrastructure and Industrial & Commercial) experienced a decrease in Q2 2011 compared to the previous quarter.

Readers are advised:

  • Results, particularly those for the most recent quarters, are provisional and subject to revision, as later information becomes available;
  • The figures reported above are based on returns from construction firms and public sector bodies carrying out their own construction activity for the period 1st April to 30th June 2011;
  • Results are published in constant 2005 prices, seasonally adjusted, where appropriate.

Deflators adjust the value series to take out the effect of price changes to give the volume series. Deflation of construction output is carried out sectorally (i.e. New Housing, New Infrastructure etc) using a range of relevant tender price and output price indices supplied by the Office for National Statistics (ONS). Users are advised that these deflators are UK deflators and are not regional NI deflators;

Seasonal adjustment aids interpretation by removing seasonal variation due to climate, hours of daylight, holidays or other regular seasonal patterns.
