Notes

About this issue

This publication updates the preliminary estimates released in Construction Work Done, Australia on 24 February 2021. The data in this publication are based on a response rate of approximately 90% of the value of building work done during the quarter. The data are subject to revision when returns from the following quarter are processed. Final data for the December 2020 quarter will be released in the next release of this publication, Building Activity, Australia on 14 July 2021.

Significant revisions this issue

Compared to the estimate published in Building Activity, Australia September 2020 released on 20 January 2021:

  • the total value of work done in Australia during the September 2020 quarter has been revised upwards by $601.6m or 2.0% (original, current price). 
  • the total value of work commenced in Australia during the September 2020 quarter has been revised upwards $674.6m or 2.5% (original, current price). This was driven by an upward revision to total non-residential commencements of $262.2m (2.8%), and an upward revision to total residential commencements of $412.4m (2.4%).
  • the number of dwelling unit commencements in the September 2020 quarter has been revised upwards by 440 dwellings or 1.0% (original).

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.

Suspension of trend series

The trend series attempts to measure underlying behaviour in construction activity. This measurement will be significantly affected by changes to regular patterns in activity during this time, as the construction industry faces on-going uncertainty. If the trend estimates in this publication were to be calculated without fully accounting for this irregular event, they would likely provide a misleading view of underlying building activity.

It may be some time before the underlying trend in building activity can be accurately estimated. The trend series have therefore been suspended starting from June 2020. The trend series will be reinstated when more certainty emerges in the underlying trend. 

Update to seasonal adjustment methods

Building Activity uses the concurrent seasonal adjustment method, meaning that seasonal factors are re-estimated each time a new data point becomes available. If not appropriately accounted for, unusual real-world events, such as COVID-19, can distort estimates calculated using this method. From September 2020, seasonal factors for Private sector non-residential building work done in Victoria are being calculated using data up to and including June 2020, then projected from September 2020 onwards. From December 2020, seasonal factors for Private and total sector commencements for new houses and alterations and additions are being calculated using data up to and including September 2020, then projected from December 2020 onwards. This approach, known as the forward factor method, ensures that the seasonal factors are not distorted by COVID-19 impacts.
