ACCIONA together with joint venture partner Ferrovial have delivered a southern-hemisphere first when two tunnel boring machines (TBMs) have simultaneously broken through a wall of rock to arrive at Five Dock Metro Station.
ACCIONA Chief Executive Officer Australia & New Zealand, Bede Noonan said it was amazing to see these two TBMs punch through together.
ACCIONA Chief Executive Officer Australia & New Zealand, Bede Noonan said everyone involved should be very proud to be part of such a significant and unique milestone.
“Delivering on this simultaneous TBM breakthrough reinforces the capability and expertise of our team - I congratulate you all on this amazing feat.
"It’s a testimony to everyone’s hard work and dedication on this city-shaping project.” Bede said.
TBM Daphne broke through first, followed closely by TBM Beatrice, after building the 4.3-kilometre section of metro tunnel from The Bays to Five Dock for around seven months.
The two 1,300-tonne TBMs will spend the next few weeks traversing to the western end of the station cavern. During this time, the machines will undergo all necessary maintenance before being relaunched to continue their journey to Sydney Olympic Park.
To date, the huge machines have excavated a total of 437,463 tonnes of material each and installed about 30,732 precast concrete segments to line the new tunnel walls.
To prepare for the arrival of the TBMs, the Five Dock station cavern was excavated with about 286,047 tonnes of material removed to create the underground box-like structure that is 22 metres wide and 15 metres high.
Next stop for the TBMs is the Burwood North Metro Station site about two kilometres away, where they are due to arrive in early 2024.
