The John Holland CPB Ghella Joint Venture’s (JV) tunnelling and station excavation works for the Sydney Metro City and Southwest Project has received international recognition.
The ITA Tunnelling and Underground Space Awards is an international competition that seeks to reward ground-breaking innovation and outstanding projects in the sector.
ITA said despite the challenging year, the awards received 52 entries from 23 countries and saw more than 1,200 attendees from around the world attend the virtual event.
The John Holland CPB Ghella Joint Venture Tunnelling and Station Excavation Works for the Sydney Metro City and Southwest Project took home the ‘Major Project of the Year’ award, being Australia’s biggest public transport project and the first Australian project to have five tunnel boring machines (TBMs) building simultaneously.
The TBMs worked under the Sydney Harbour and through the congested underground CBD environment, while the project’s roadheaders created some of the largest caverns in Australia.
ITA said the project had many other major achievements to recognise, such as two dives and permanent portal structures implemented, three open station boxes, three underground mined stations and more.
“The impressive works were also operated with the excavation of two twin 15.5 km fully lined tunnels between Chatswood and Marrickville with 57 cross passages,” the organisation said.
