Completing excavation process of the 11km tunnels from The Bays to Sydney Olympic Park, TBMs Daphne and Beatrice have broken through at Sydney Metro West’s future Sydney Olympic Park station.
The quantity of removed material over 18-month journey of these the 7m-diameter double shield hard rock TBMs was more than 2 million tonnes, whereas installing 72,456 segments.
Currently, the aim of work inside the 200m-long, 37m-wide, and 27m-deep station box at Sydney Olympic Park will be dismantling the TBMs and getting the box ready for station construction, while the cross-passages are now going to be completed in the tunnels.
In order to daily use, Sydney Olympic Park metro station is due to feature an underground island platform, plus two additional side platforms to provide increased capacity during events.
Following arriving at Five Dock Station site minutes apart to achieve the first double TBM breakthrough in the southern hemisphere, TBMs Beatrice and Daphne made tunneling history in previous year.
Considering that Department for Planning, Housing and Infrastructure has approved plans for a new town centre that will create over than 300 new residential dwellings in Sydney Olympic Park, the latest breakthrough coincides with another major landmark for Sydney Metro West.
The advantages of Sydney Metro West project will be doubling rail capacity between Greater Parramatta and the Sydney CBD, and make it easier and faster to travel around western Sydney.
