Building Anzac Station
Construction of Anzac Station is now underway on St Kilda Road.
The station will be built via a cut and cover method, using the ‘top down’ approach.
The walls of the station will first be built into the ground through a series of diaphragm walls, or D-walls. Once the walls of the station are set, excavation equipment will then dig out the top few metres of the station box. A new permanent concrete slab is then poured at this level, forming the roof of the station box. Once the roof is in place, a temporary acoustic shed will be installed over the northern end of the station box, excavation of the station will take place 24/7 under the roof slab and acoustic shed.
Anzac Station will also play a key role in supporting the project's construction activities south of the Yarra River.
Tunnel boring machines (TBMs) will be launched from Anzac Station towards the eastern tunnel entrance in South Yarra, they will be retrieved and taken back to Domain, before being re-launched and tunnelling towards the new underground station at the southern end of Swanston Street.
Key construction activities for Anzac Station include:
- Tree protection and removal.
- Relocation of underground services such as water, sewerage, gas, power and telecommunications.
- Establishment of the tunnelling support site at Edmund Herring Oval.
- Reconfiguration of St Kilda Road to allow traffic, trams and cyclists to keep flowing around the construction site.
- TBM launch and support site.
- Excavation of the station box and construction of a diaphragm wall.
- TBM launch.
- Structural works including the station entrance connections.
Construction traffic routes for the St Kilda Road precinct aim to move trucks and other construction traffic between the site and Kings Way / CityLink as directly as possible.
What we are doing
Construction works are continuing within the St Kilda Road site throughout November and will include:
- Ongoing site establishment works
- Station box construction
- Construction of new section of road between Bowen Lane and Albert Road
- Removal of the covered walkway
- High voltage cable relocation
- Geotechnical investigations and soil sampling.
Ongoing site establishment works
Site establishment activities will continue and include the construction of hard hoarding fencing and galvanised chain mesh fencing around the worksite. Please refer to the map overleaf for fencing type by location.
Station box construction
Station box construction activities are continuing in the northern and southern sections of the Anzac Station box. These works include:
- Construction of Diaphragm walls (D-walls) in the northern section of the station box
- Construction of guide walls around the southern section of the station box
- Construction of a retaining wall on the northern boundary of the southern section of the station box.
These activities will involve regular deliveries to site and the removal of spoil (dirt).
Geotechnical investigations and soil sampling works are continuing in the Domain Precinct to assess ground and environmental conditions.
Existing groundwater monitoring wells may be accessed to measure groundwater levels. This will require up to two workers accessing the wells for approximately 10 minutes.
High voltage cable relocation
Early November - for approximately four weeks
Works will commence on the relocation of a high voltage cable beneath the footpath on St Kilda
Road from Bowen Crescent to Bowen Lane.
During these works pedestrians will be required to detour onto a temporary path adjacent to the existing path. Access to residential buildings and businesses will be maintained at all times for both pedestrians and vehicles.
Some parking spaces on Bowen Crescent will be occupied for up to three days during these works.
It is estimated that construction activities in the Anzac Station precinct will take around five years. Surface disruption is expected to be shorter than the overall construction time. Project wide rail systems installation will occur after this.
The Metro Tunnel is on track to be completed by 2025, which accounts for construction works above and below ground, tunnels and stations fit-out, as well as installation and testing of critical safety systems and the high capacity signalling which needs to be integrated with existing network systems.
The estimated project timelines are due to the scale and complexity of the Metro Tunnel construction, along with Melbourne's challenging ground conditions. Rail Projects Victoria (RPV) and the construction contractors will work to deliver the project to Victorians as early as possible while maintaining the highest safety and quality standards.
