Sydney Metro City & Southwest Wins Australia’s Top Construction Award

Sydney Metro City & Southwest tunnel and station excavation

The 2022 Australian Construction Achievement Award (ACAA) has been won by the Sydney Metro City & Southwest tunnel and station excavation works by John Holland, CPB Contractors and Ghella Joint Venture.

Comprising of 15.5km twin rail tunnel, dive structures, and six complex underground stations between Chatswood and Sydenham, as well as the first rail tunnels under Sydney Harbour, this project was delivered in the heart of Sydney’s central business district.

Sydney Metro project, which attained the highest ever ISC Infrastructure Sustainability rating, involved a team of 11,000 people working in challenging geotechnical conditions alongside heritage and live transport infrastructure.

Due to the numerous existing infrastructure assets beneath the harbor, mining under heritage buildings, and the design and construction of massive bespoke formwork for an underground station, the works were further complicated.

According to Australian Constructors Association CEO Jon Davies: ” The industry continued to rise to the challenges it faced. This year’s winner delivered several Australian firsts that would not have been possible without the one-team culture established from the outset. All finalists have demonstrated that our industry is at its best when it works together.”

Engineers Australia CEO Dr. Bronwyn Evans congratulated the winning team for delivering a masterpiece of engineering innovation.

“John Holland, CPB Contractors, and Ghella Joint Venture have given a masterclass in using innovative engineering solutions and teamwork to overcome the most complex environmental and logistical challenges imaginable. In doing so, they have delivered an iconic addition to Sydney’s DNA that will provide enormous benefit to everyone in the community,” she said.

The Host of ACAA, which is now in its 25th year, is the Australian Constructors Association and Engineers Australia, while it is the top annual award for the major players in Australia’s construction industry.
