About this issue

This publication updates the preliminary estimates released in Construction Work Done, Australia (cat. no. 8755.0) on 26 May 2021.

Data note

This release includes revisions to Engineering Construction data back to December 2020.

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.  

Mining projects tend to be complex in structure and comprise a number of different investment activities including exploration, engineering construction, plant and equipment and buildings. A feature article released in the March 2012 issue of Private New Capital Expenditure and Expected Expenditure, Australia (cat. no. 5625.0) provides a summary of the conceptual basis of the relevant ABS publications that measure investment in Australia, using a hypothetical mining project to illustrate how this investment is reflected in ABS data.

Managing the impact of Coronavirus (COVID-19) on engineering construction statistics

The ABS is currently monitoring for potential impacts from the Coronavirus (COVID-19) on construction activity statistics and will continue to do so for the period of the pandemic.

Quality assurance of March 2021 quarter data did not identify any significant impact to headline statistics. The designation of construction as an essential service enabled activity to progress despite social distancing restrictions implemented from late March 2020.

The ABS is actively managing the potential risks from COVID-19 to data collection operations. The ABS appreciates the support of survey respondents in continuing to provide the data to compile this publication.

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 construction activity.

It may be some time before the underlying trend in construction 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.
