Good afternoon everyone,
We hope you enjoyed your long weekend, and have had a lovely week so far.
We are writing today with our next weekly construction lookahead.
ANZAC STATION WEEKLY LOOK AHEAD
Tunnelling and TBM support site
TBM Millie has completed over 1.4 kilometres of tunnel, with TBM Alice having completed over 700 metres. TBM Millie has now passed Alexandra Avenue and is nearing Peppercorn Lawn. TBM Alice is also making great progress and has now passed Government House Drive along St Kilda Road.
The slurry treatment plant at Edmund Herring Oval continues to operate, treating the spoil coming from TBMs Millie and Alice. Trucks for spoil disposal will continue for the duration of tunnelling in the East.
Station box construction
This week, the team in the south box completed a blinding layer of concrete where the sacrificial tunnels have been removed so that they can continue to install the falsework deck for the next concourse level slab pour. As we mentioned last week, the falsework is a temporary decking structure that is installed to bring us up to the required height to form and pour the concourse slab. The scaffolding for this falsework deck will continue being lowered to the workers through the void for installation. This week, we’ve included a picture of the falsework starting to take shape. This will eventually form the support structure to construct the concourse slab. In the background of the photo, you can see part of the concourse slab in the southern end of the box that has already been constructed.
Next week, steel for the concourse slab will begin arriving to site for installation, and will continue until the end of the month. Most steel will be fed down to workers through the void by the large crane on surface during normal working hours, but sometimes may be required up until 10pm.
In the northern end of the station box, next week the team will continue installing the falsework and steelfixing to construct the columns from base slab level to concourse slab level.
Anzac Station entrance construction – Tram Interchange
This week, work has continued breaking back the support piles to their correct height, which does generate periods of high level noise. This pile breakback will continue until early next week.
Next week, under the suspended roof slab, works to construct the base slab of the entrance will commence with waterproofing works, steelfixing and concrete pours.
At the same time, the team will continue the detailed excavation of the pits and conduit trenches where the piles were installed.
Anzac Station entrance construction – Shrine of Remembrance
At the Shrine entrance, this week work has continued on installing the steel for the second roof slab pour.
Next week, waterproofing works will commence on the completed section of the roof slab, while crews continue installing falsework and steelfixing in preparation for the next roof pour for this station entrance site.
