ABOUT THIS ISSUE

This publication provides an early indication of trends in building and engineering construction activity. The data are estimates based on a response rate of approximately 85% of the value of both building and engineering work done during the quarter. More comprehensive and updated results will be released in Engineering Construction Activity, Australia (cat.no. 8762.0) on 16 January 2013 and in Building Activity, Australia (cat. no. 8752.0) on 17 January 2013.


CHANGES IN THIS ISSUE

From the September 2012 release, the Value of building work in the pipeline and the Number of dwelling units approved not yet commenced series previously published in tables 15 and 16 and Time Series spreadsheets 11, 12 and 13 are no longer included in Construction Work Done, Preliminary, Australia (cat. no. 8755.0). The data contained within these tables and spreadsheets will be included in the publication Building Activity, Australia (cat. no. 8752.0) from the September quarter 2012 issue onwards. Table 10 of the Time Series spreadsheets, as released previously, has also been removed. This data is available in Time Series spreadsheet Table 8 of this publication.

A new base year, 2010-11, has been introduced into the chain volume estimates which has resulted in revisions to growth rates in subsequent periods. In addition, the chain volume estimates have been re-referenced to 2010-11, thereby preserving additivity in the quarters after the reference year. Re-referencing affects the levels of, but not the movements in, chain volume estimates. For further information, see the explanatory notes.


DATA NOTES

Trend estimates should be interpreted with caution. Building activity trends may be affected by Government stimulus packages and other developments associated with global economic conditions. Engineering trends may be affected by the volatility caused by large engineering projects. For more details on trend estimates, please see paragraphs 24 to 26 of the explanatory notes.
