ABOUT THIS ISSUE

This publication updates the preliminary estimates released in Construction Work Done, Australia (cat. no. 8755.0) on 25 November 2015.


CHANGES THIS ISSUE

A new base year, 2013-2014, has been introduced into the chain volume estimates which has resulted in revisions to growth rates in subsequent periods. In addition, the chain volume measures have been re-referenced to 2013-2014, preserving additivity in the quarters after the reference year. Re-referencing affects the levels, but not the movements in, chain volume estimates.


DATA NOTE

This release includes revisions to Engineering Construction data back to June 2015.

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 for quarterly work done on Engineering Construction in the Northern Territory have been reinstated for the period between September 2014 and June 2015 in this release. The ABS has reviewed the estimates for this period and a trend break has been inserted in the September 2014 quarter.

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.
