Sydney Metro has submitted for assessment to the Department of Planning, Industry and Environment the Environmental Impact Statement for the Sydney Metro West Project Concept from Westmead to the Sydney CBD. This includes State 1 works for station excavation and tunnelling between Westmead and The Bays. This planning document in now on public exhibition.
Sydney Metro West stations would be either cut-and-cover or binocular. A cut-and-cover station involves excavating a rectangular hole in the ground, which would then house the underground station.
A binocular station involves digging a smaller shaft from ground level to the depth of the station and then mining two underground station caverns.
Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North and The Bays would be cut-and-cover stations. Five Dock would be a binocular station.
Four tunnel boring machines (TBMs) would be required to carry out the tunnelling. Two TBMs would be launched from Westmead and two from The Bays.
The machines will meet at Sydney Olympic Park and be retrieved from the Sydney Olympic Park metro station site.
The environmental assessment process for Sydney Metro West will be staged in recognition of the size of the project.
Future project approvals will consider all stations, depots and rail systems between Westmead and The Bays and all major civil construction works including station excavation, tunnels, stations, depots and rail systems between The Bays and the Sydney CBD Station.
