The Australian Constructors Association (ACA) together with Engineers Australia has announced that four projects have been selected as finalists to compete for the 2021 Australian Construction Achievement Award (ACAA). The combined value of the projects is approximately two billion dollars.

“The finalists have demonstrated world-class expertise in addressing the growing complexity of today’s projects. In delivering these projects, the finalists developed collaborative cultures that helped to overcome challenges, while also providing opportunities for greater training and upskilling. These are critical elements for sustaining the industry,” said ACA CEO Jon Davies.

“We congratulate all the finalists for the 2021 award. To achieve these extraordinary outcomes in a time of such profound difficulty is a testament to the strength and resilience of Australia’s construction and engineering workforce,” said Engineers Australia CEO Dr Bronwyn Evans.

Now in its 24th year, this premier construction industry Award has again been partnered by some of the major businesses connected with the industry including Caterpillar, Cbus, Holcim, Infra Build and Oracle Construction and Engineering.
