This bulletin shows output in the construction industry for the third quarter of 2012. Most figures are estimates in constant (2005) prices, seasonally adjusted. The overall estimate for construction output this quarter was 2.6 per cent lower compared with the previous quarter, with volume reductions in seven of the nine sectors. The largest of these reductions, both in value and percentage terms, was in private commercial, which fell by £452 million and 8.2 per cent respectively.
Further breakdowns, including non-seasonally adjusted and current price series, can be found in the data tables (625.5 Kb Excel sheet) . This publication focuses on the latest quarterly figures, but also includes the latest annual and monthly estimates as well as revisions to earlier periods in line with our revisions policy.
The preliminary estimate of quarter three 2012 Gross Domestic Product (GDP) included a nowcast fall of 2.5 per cent in construction output in the third quarter of 2012 compared with the previous quarter.
The estimate released in this publication show that construction output fell by 2.6 per cent in the third quarter.
There is, therefore, a negligible impact on the preliminary quarter three 2012 GDP estimate from this release of construction output estimates.
New work in the third quarter of 2012 fell by 2.2 per cent compared with quarter two. The largest fall was in private commercial which fell by 8.2 per cent. The only sectors that increased were infrastructure and private industrial which increased by 9.9 per cent and 0.3 per cent respectively, although the latter sector is small (approximately 5 per cent of total new work). The private commercial sector, however, accounts for approximately 34 per cent of new work while the infrastructure sector accounts for approximately 18 per cent. Thus, the larger growth in infrastructure did not offset the smaller decline in private commercial.
Repair and maintenance work fell by 3.2 per cent with falls in all sectors except public housing.
Over the year from the third quarter of 2011 to the third quarter of 2012, there was an 11.3 per cent fall in total construction output. New work fell by 14.5 per cent with decreases in all sectors other than private industrial, but this is a small sector. The largest falls in new work were seen in public non-housing (19.7 per cent) and private commercial (17.4 per cent). Repair and maintenance output fell by 4.8 per cent over the same period. The only sector of repair and maintenance that grew in this period was public housing (2.6 per cent).
Since the fourth quarter of 2010, new work in the public sectors (public housing and public non-housing) have seen almost continuous decline. Whereas some new work in the private sectors have shown growth in certain quarters since the fourth quarter of 2010, overall new work has fallen every quarter from Q3 2011.

The volume of new private housing work in the third quarter of 2012 was 4.0 per cent lower compared with the previous quarter and 10.6 per cent lower than the same quarter in 2011.
The volume of new public housing work in the third quarter of 2012 was 0.5 per cent lower compared with the previous quarter and 18.7 per cent lower than the same quarter in 2011. There has been a downward trend in this sector since the fourth quarter of 2010.
Following two quarters of falls in output the volume of new infrastructure output in the third quarter of 2012 was 9.9 per cent higher compared with the previous quarter. Compared with the same quarter a year ago, infrastructure new work fell by 11.3 per cent.
The volume of new work in the public non-housing (excluding infrastructure) sector in the third quarter of 2012 was 0.6 per cent lower compared with the previous quarter and 19.7 per cent lower compared with the same quarter in 2011. This sector has been declining since the fourth quarter of 2010, although the latest quarter-on-quarter decline is less sharp than in earlier quarters.
The volume of new construction in the private industrial sector in the third quarter of 2012 grew by 0.3 per cent compared with the previous quarter and was 4.1 per cent higher than the same period in 2011. This sector has been reasonably flat from the fourth quarter of 2010.
The volume of new construction in the private commercial sector in the third quarter of 2012 fell by 8.2 per cent compared with the previous quarter and was 17.4 per cent lower than the same period in 2011.
The volume of housing repair and maintenance work (including improvement work) in the public sector in the third quarter of 2012 was 2.2 per cent higher compared with the previous quarter and 2.6 per cent higher than the same quarter in 2011. This sector has been reasonably flat from the beginning of 2011.
The volume of housing repair and maintenance work (including improvement work) in the private sector in the third quarter of 2012 was 2.8 per cent lower compared with the previous quarter and 7.1 per cent lower compared with the same quarter in 2011. The quarter-on-quarter decline continues the trend seen in recent quarters.
As public housing is approximately 37 per cent of housing repair and maintenance and private housing is approximately 63 per cent, the relative growths in these sectors do not offset one another.
The volume of repair and maintenance in the non-housing sector in the third quarter of 2012 was 5.1 per cent lower compared with the previous quarter and 5.9 per cent lower compared with the same quarter in 2011. The introduction of an infrastructure repair and maintenance question in only 2010 means that we do not yet have sufficient data to produce seasonally adjusted estimates for the components of this series.
In general revisions will follow the standard revisions policy for construction statistics shown in the table below.

Special Events Policy
The Olympics took place from 27 July to 12 August 2012 (with a few events starting on 25 July), and the Paralympics from 29 August to 9 September. For most economic statistics, any direct effect of the Olympics was mainly reflected in the August estimate, although some of the Paralympics-associated activity took place in September. Wider effects, for example, if the presence of the Olympics has influenced the number of non-Olympics tourist visits, may of course affect any of the summer months.
This commentary is intended to help users to interpret the statistics in the light of events. As explained in ONS’s Special Events policy. It is not possible to make an estimate of the effect of the Olympics and Paralympics on particular series only on the basis of information collected in those series. More details of how certain series are affected are in an Information Note, and an article explaining how various elements are reflected in the National Account was published in July 2012.
Changes to Construction Statistics
In June 2009 ONS announced major changes to the arrangements for producing construction statistics and indicated that the changes would take effect from the beginning of 2010. From January 2010, a new Monthly Business Survey replaced the quarterly output surveys for construction, and a quarterly new orders survey replaced the previous monthly new orders survey.
Relevance to users
The statistical bulletin brings together information on the output of the construction industry in Great Britain. It draws on data compiled from the Monthly Business Survey, with businesses selected from the Inter-Departmental Business Register (IDBR). The construction industry, which contributes to the overall estimate of Gross Domestic Product (GDP) by approximately 6.8 per cent, covers Sections 41, 42 and 43 of the Standard Industrial Classification 2007 (excluding section 41.1 (property developers)).
Similar data for Northern Ireland is provided by the Northern Ireland Statistics and Research Agency.
Information relating to employment in the construction industry is available in the Labour Market Statistics Statistical Bulletin.
Revisions to previous periods: Figures for the recent months are provisional and subject to revision as later information becomes available.
Deflation and seasonal adjustment
'Value' of construction output is also known as 'current price' or 'nominal price' construction output. 'Volume' of construction output is also known as 'constant price' construction output. A volume series aims to measure the level of construction output, adjusting for price inflation, allowing comparisons of activity to be made between periods. Deflators adjust the value series to take out the effect of price changes to give the volume series. Deflation of output is carried out sectorally, and a range of relevant tender price and output price indices are used.
The headline data are given in constant 2005 prices, seasonally adjusted. Seasonal adjustment aids interpretation by removing annually recurring fluctuations, for example, due to climate, hours of daylight, holidays or other regular seasonal patterns. Unadjusted data are also available.
Seasonally adjusted monthly estimates will not be available until enough monthly data are available for this to be done reliably. After three years of estimates are available, ONS will review if it is feasible at that point.
