Bayswater Community Zone
Concrete pours are ongoing for the construction of the base slab for the Bayswater dive structure. Building the base slab requires pouring 4050 cubic metres of concrete, separated into 18 sessions.
Due to the complexity of each pour, works are required to start early guaranteeing minimal disruption from traffic. Once a pour begins it needs to continue until completed. On the day of the pours, work will begin from 4am and continue during normal construction hours, finishing at 7pm. Out of hours approval has been received from the City of Bayswater. The dates of each of the pours may change depending on weather conditions and construction schedules:
- Pour 14 - Thursday 6 (complete)
- Pour 15 - Friday 14 (complete)
- Pour 16 - Friday 21
- Pour 17/18 - Wednesday 26
Excavation of the dive structure expected to be completed by early June. To date, more than 60,000 tonnes of soil has been removed.
Two parallel retaining walls are currently being constructed at the western end of the site – one to retain vegetation and the other to separate the rail reserve from the principal shared path (PSP). Both are expected to be finished mid-year.
At the tunnel portal, where the TBMs will break through at the end of their underground journey, walers that were installed to support the adjoining d-walls are currently being removed. With the concrete slab complete at the portal end, the area is now structurally self-supporting.
