These spreadsheets contain revised data for some of the chain volume measures series released in Construction Work Done, Australia, Preliminary, cat. no. 8755.0. This data is sourced from, and more comprehensive results are available in Building Activity, Australia (cat. no. 8752.0) and Engineering Construction Activity, Australia (cat. no. 8762.0). The notes below relate to these two publications.
BUILDING ACTIVITY, AUSTRALIA, September 2014 (cat. no. 8752.0)
DATA NOTE
Several time series spreadsheets contain 'np' (not available for publication) annotations from the September quarter 2012 onwards. This is due to confidential data being contained in these series.
A new base year, 2012-13, has been introduced in the chain volume estimates resulting in revisions to growth rates in subsequent periods. In addition, the chain volume estimates have been re-referenced to 2012-13, 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.
ENGINEERING CONSTRUCTION ACTIVITY, AUSTRALIA, September 2014 (cat. no. 8762.0)
DATA NOTE
Several time series spreadsheets for recent quarters contain 'np' (not available for publication) annotations. This is due to confidential data being contained in these series.
Trend estimates should be used with caution due to the volatility caused by large engineering projects. For more details on trend estimates, please see paragraphs 22 to 24 of the explanatory notes.
