TBMs Daphne and Beatrice broke through to the Five Dock Metro Station site, making Sydney Metro West the first project?in the southern hemisphere to achieve a double TBM breakthrough. They will soon start building from the Five Dock Metro Station site to Burwood North Station site.
Hundreds of pre-cast tunnel segments have been delivered to The Bays Metro Station site, ready to meet the machines as they progress up to 90m below Sydney’s inner west.
Each day, more than 250 precast tunnel segments will be transported from The Bays, through the newly built tunnels beneath Iron Cove to Five Dock, where they will meet Daphne and Beatrice.
TBMs Beatrice and Daphne launched last year from the western side of The Bays Station. Both machines have installed approximately 30,700 of 150,000 segments that will line the new tunnel walls.
At the eastern end of the site, work has commenced to prepare the 32m-deep station box for two new TBMs that will launch from The Bays to tunnel under Darling Harbour towards the city in mid-2024.
These TBMs, each weighing about 1,300 tonnes, are the final two of six for Sydney Metro West.
A second shed on the western side of The Bays site is being used to store excavated material after it is transferred from the TBMs on conveyor belts. The shed holds a maximum of 40,000 tonnes of material that is continuously being moved for reuse on other sites across Sydney.
The 24km-long Sydney Metro West is expected to be completed by 2032.
