The Rookwood Weir Project by Sunwater, GHD, ACCIONA & McCosker Contracting was announced as the winner of the 2024 Australian Construction Achievement Award (ACAA) at a black-tie award dinner at The Doltone House in Sydney, in conjunction with the Foundations and Frontiers forum (FF24).

Australian Constructors Association CEO Jon Davies said, “This award is one of the highest honours a project can receive, recognising not only construction excellence but also the forward-thinking initiatives that contribute to a more sustainable industry.”

“The Rockwood Weir project is a worthy winner,” said Mr Davies.

“Constructed on the Fitzroy River, the second largest seaward catchment in Australia, the project was a highly complex build with significant risks. These risks were minimised thanks to the exemplary collaboration of the alliance.

“The project excelled in lifting the skills base within this sector, exceeding its training targets by achieving 106.9% for ‘New Entrant’ training hours and 209.8% for ‘Other Workforce’ training hours. The project also significantly surpassed its Indigenous employment targets, engaging 81 Aboriginal and Torres Strait Islander personnel, far exceeding goals,” said Mr Davies.

Engineers Australia CEO Romilly Madew AO said, “The finalists’ projects showcase the power of collaboration and creativity. By integrating sustainable practices and cutting-edge engineering and technology they have shown that the construction industry can lead the way in environmental responsibility and innovation.”

“One of the standout features of the Rookwood Weir Project is its technically complex fishlock and the world-first design turtle passage. Informed by the largest freshwater turtle telemetry project in the world, it is the first passage in Australia to provide safe upstream and downstream movement for turtles,” said Ms Madew.

Now in its 27th year, this premier construction industry Award has again been partnered by some of the major businesses connected with the industry including Caterpillar, Cbus, Gallagher, InEight and InfraBuild.

The ACAA finalists for 2024 were:
