The 2023 Australian Construction Achievement Awards (ACAA) have celebrated infrastructure projects from around Australia for their innovation, teamwork and skill – announcing this year’s project finalists and winners on 3 May. 

The M80 Ring Road Upgrade from Sydney Road to Edgars Road in Melbourne won the 2023 Australian Construction Achievement Award (ACAA) for its transformation of one of Melbourne’s busiest freeways, providing additional capacity and improving safety for over 165,000 drivers each day.

The upgrade team widened 5.7km of freeway; adding additional lanes, ramps, collector distributors and a smart freeway system – all in and around live traffic flows. 

The project was completed a year ahead of schedule and under budget.

Australian Constructors Association CEO, Jon Davies, said, “The award is one of the highest forms of recognition for a project because it not only recognises traditional construction excellence, but also excellence in initiatives designed to make the industry a more efficient and better place to work.

“The CPB Contractors and Major Road Projects Victoria M80 project team set a new standard for diversity and inclusivity. They achieved a representation of 3.1 per cent Aboriginal employees and a leadership team of 40 per cent women, while 30 per cent of the overall project workforce is also comprised of women.

“This diverse team achieved remarkable success, driven by a cohesive ‘one team’ culture that fostered collaboration and innovation from the very beginning. This culture paved the way for exceptional achievements, such as being the first freeway to incorporate recycled content in every pavement layer.”

Engineers Australia CEO, Romilly Madew, praised the finalists for responding to industry challenges to bolster the sector and continue to strive for excellence in construction.

“Covid-19 disruptions to supply chains and project schedules, economic factors and shortages of skilled personnel in key areas – engineering being one of them – have combined to challenge the sector,” Ms Madew said.

“In trying times, constructors have relied on strong and positive workplace cultures and uncompromising standards of safety and quality. They have embraced technological advances in planning, design and project management, to earn their place among the stable of finalists.”
