Northern Ireland Construction Bulletin - Q2 2013

Stormont Executive press release - Department of Finance and Personnel

The Northern Ireland Statistics and Research Agency (NISRA) today published the latest edition of the Northern Ireland Construction Bulletin (

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 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 the second quarter of 2013 decreased by 5.4% compared to Q1 2013 and was 5.1% lower compared to the same quarter in 2012.

This latest quarterly decrease follows two successive quarters of positive growth in construction output.

The value of construction output in real prices in Q2 2013 was estimated to be £452million, the lowest quarterly value reported in the current series. The level of output reported in Q2 2013 is in the region of 40% lower than the levels of output reported in the quarters before the downturn in 2007.

All the sub-sectors of construction experienced a decrease in Q2 2013.

In Q2 2013, Great Britain experienced positive growth with overall construction output increasing by 2.0% compared to the previous quarter.

In Q2 2013, construction output in Northern Ireland was three-fifths (62%) of the average output reported for 2005. In the same quarter, overall construction output in Great Britain was at 87% of the average output for 2005.

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 1 April to 30th June 2013;

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.


Users are advised that some of the Construction Output Series are presented in Constant (2005) Prices only as they are no longer considered to be seasonal. The Background Notes (point 9) in the Northern Ireland Construction Bulletin Q2 2013 advises which series have changed. For those series which are still considered to be seasonal, figures are presented in Constant (2005) Prices Seasonally Adjusted.
