CYP Update April 30`

Good afternoon everyone,

We hope you’ve been having a lovely week.

We are writing today with our next weekly construction lookahead.

Tunnelling and TBM support site

TBM Alice has completed 1.6 kilometres of the 1.8 kilometre journey to the Town Hall Station. Currently, she is tunnelling opposite the platforms of Flinders Street Station, and is very close to Town Hall Station.

The slurry treatment plant at Edmund Herring Oval continues to operate, treating the spoil coming from TBM Alice. Trucks for spoil disposal will continue for the duration of tunnelling in the East.

The first rear gantry from TBM Mille has now been pulled back through the tunnel to Anzac Station. Over the coming weeks you’ll see sections of the TBM removed from the acoustic shed and stored to the side ahead of their removal from site via truck.

Anzac Station entrance construction – Tram Interchange

The first concrete pour for the tram interchange station entrance was completed earlier this week.

Next week, work continues on waterproofing and steelfixing in the remaining sections of the entrance, preparing for the next concrete pour.

As we mentioned in last week’s look-ahead, steel fixing is one of the quieter activities as it is done largely by hand, in the coming weeks there may be some steel fixing carried out up until 10pm in the tram interchange. Any steel will be pre lowered into the box prior to 6pm to avoid unnecessary disruption. At this stage it’s unlikely any extended hour steel fixing will be required next week.

Anzac Station entrance construction – Shrine of Remembrance

Backfilling work is nearly complete at the Shrine Entrance, with crews working to asphalt the area ahead of handover to the tunnelling team for storage. The completion of backfilling means that stage one of the Shrine entrance is now complete.

Station box construction

In the southern section of the station box, work has begun to excavate down to the base slab level, which includes the demolition and removal of the next stretch of sacrificial tunnel. We’ve included a picture from the first day of the phase two of excavation, which shows the blinding layer of concrete being broken out ahead of excavation down to base slab level.

As we mentioned last week, we will trial 24/7 excavation underground. Excavators will be running under the concrete decks after 10pm and we will closely monitor the noise during this time. A member of the environment team will be out on site conducting monitoring on the first night of works.

From Monday next week, crews will be loading trucks on the surface up until 10pm with excavated material to drive from site. As with the underground excavation, the lessons learned from last time will be applied – with all light towers running off mains power and the excavator operators barred from using the bucket on concrete to scrape up loose material.  Loadout from 6pm to 10pm will only be of softer materials with no load-out of concrete segments into truck beds.

This Saturday, crews will be loading out on the surface until 3pm, as excavation continues beneath the roof slab.

Over in the northern end of the station box underneath the acoustic shed, the team continues to construct internal columns, and install falsework and steelfixing for the next concourse slab pour.

Clothing moths

A couple of people have said that they have had some damage to their clothes from clothing moths. If you have had issues, these seems to be successful…from Bunnings

Also good it you tell Paul so he has some idea of how many people are having issues

Free coffee??

I hope you all like the new electronic displays in the lifts. I’d like to thank Graeme for his efforts in making this all happen.

Luckily I’m on Level 7 and that gives me more time to read the various screens of information. I THINK that there is one with a free coffee offer, but I have not seen it yet??

Is that Simon from Level 3 in the Degraves Lane shot??

CYP Update

Lots happening underground this week and last


Good afternoon everyone,

We are writing today with our weekly construction lookahead.

As you would be aware, Anzac Day is this Sunday, 25th April. There will be no construction activities on site on Sunday, other than the minimum required to maintain safe operation of the one TBM still tunnelling towards Town Hall Station.  

The Anzac Station and Edmund Herring Oval site lights will be switched off ahead of the Dawn Service to help support the respectful observance of Anzac Day.

ANZAC STATION WEEKLY LOOK AHEAD

Tunnelling and TBM support site

TBM Alice has completed 1.5 kilometres of the 1.8 kilometre journey to the Town Hall Station. Currently, she is now underneath the Yarra River on the approach to Town Hall Station.

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.

The first rear gantry from TBM Mille will be pulled back through the tunnel to Anzac Station next week, over the coming weeks you’ll see sections of the TBM removed from the acoustic shed and stored to the side ahead of their removal from site via truck.

Anzac Station entrance construction – Tram Interchange

On Tuesday next week the team will pour the first section of the base slab for the tram interchange entrance. The section to be poured is the northern most section underneath the suspended slab. On the day two concrete pumps will be set up at the northern end with concrete trucks arriving to site throughout the day.

Waterproofing and steel fixing will continue in the remaining sections.

As we mentioned in last week’s look-ahead, steel fixing is one of the quieter activities as it is done largely by hand, in the coming weeks there may be some steel fixing carried out up until 10pm in the tram interchange. Any steel will be pre lowered into the box prior to 6pm to avoid unnecessary disruption. At this stage it’s unlikely any extended hour steel fixing will be required next week.

Anzac Station entrance construction – Shrine of Remembrance

Backfilling work is nearly complete at the Shrine Entrance, once this is done the area will be sealed ahead of the storage of the first gantry piece that will be stored on top. The first rear gantry is likely to be lifted up to surface at the back end of next week and stored. The completion of backfilling means that stage one of the Shrine entrance is now complete.

Station box construction

In the southern section of the station box we have this week removed the false work deck that we used to support the concourse level pour. The removal of the false work means that there is the room underneath the concourse to commence the second stage of excavation of the sacrificial tunnel. This will take the south box down to the base slab level.

The start of this excavation will also see the return of load-out works, with a long-reach excavators loading trucks that will drive from site. As was the case last time, the load out of excavated material will continue up until 10pm on nights. As with the underground excavation, the lessons learned from last time will be applied – with all light towers running off mains power and the excavator operators barred from using the bucket on concrete to scrape up loose material.  Loadout from 6pm to 10pm will only be of softer materials with no load-out of concrete segments into truck beds.

As we mentioned last week, we will trial 24/7 excavation underground. Excavators will running under the concrete decks after 10pm and will closely monitor the noise during this time. A member of the environment team will be out on site conducting monitoring on the first night of works.

This week we’ve included a photo looking south down the station box across the newly poured concourse level. With the falsework deck removed from underneath concourse, you can see the team clearing out the area and running lighting in preparation for the start of excavation down to the base slab level (roughly an additional 2m), while up on the concourse level the team are preparing for the construction of the internal walls on what will be the ‘back of house’ concourse area of Anzac Station.

The second photo shows the remaining section of the sacrificial tunnel that we will begin excavating next week.

Over in the northern end of the station box underneath the acoustic shed, the team have now poured two sections of the concourse slab in the north and will next week pour the third section, in addition to continuing the work on the internal columns.

Thanks, Rob and Jordan

CYP update

Good afternoon everyone,

Hope everyone has had a great week.

We are writing today with our next weekly construction lookahead.

Works this coming week are generally business as usual, with the major change being the return of excavation in the south box.

ANZAC STATION WEEKLY LOOK AHEAD

Tunnelling and TBM support site

TBM Alice has completed 1.3 kilometres of the 1.8 kilometre journey to the Town Hall Station. Currently, she has passed beneath the Queen Victoria Gardens opposite the National Gallery of Victoria and is now tunnelling beneath Alexandra Avenue as she makes her way closer to the Yarra River.

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.  

Anzac Station entrance construction – Tram Interchange

Works are largely the same as last week’s update, for those with a view over the site you’ll see the blue waterproofing being applied from north to south, in some areas it looks like we are building a series of swimming pools at the base of the interchange. These are in fact the pits for various parts of the station’s legacy infrastructure, including the base for lift wells and the base of the future escalators. We’ve attached a photo looking over the site for those without a balcony view of the works.

While the waterproofing moves forward, steel fixing for the first base slab pour is following close behind. As we mentioned in last week’s look-ahead, steel fixing is one of the quieter activities as it is done largely by hand, in the coming weeks there may be some steel fixing carried out up until 10pm in the tram interchange. Any steel will be pre lowered into the box prior to 6pm to avoid unnecessary disruption.

Anzac Station entrance construction – Shrine of Remembrance

Backfilling work continues at the Shrine of Remembrance station entrance site. This will continue for the next few weeks.

Breaking back of the retention piles down to their correct height began this week and will continue into next week, this may generate periods of high level noise.

Station box construction

In the southern section of the station box the large concrete pour that went ahead on Monday was very successful, it was over 1200m3 and was the largest concrete pour carried out on the entire project to date.

The pour is now covered and has been curing since Monday. Early next week the concourse will have cured and the team will start removing the falsework deck that supported the concourse as it was poured. Once the falsework deck is removed, work will then focus on the next stage of excavation of the sacrificial tunnel beneath the concourse slab. This excavation work is likely to start late next week.

As we mentioned in last week’s update, as part of this next stage, the team will also trial 24/7 excavation underground. During the first stage of excavation the 24/7 excavation was at times disruptive and had to be stopped on several occasions.  We will conduct a trial of excavators running under the concrete decks after 10pm and will closely monitor the noise to ensure this is not repeated. The key difference between the last stage of excavation and this one is that we are now excavating below both the roof slab and the concourse slab, and are further away from the open void.

The start of this excavation will also see the return of load-out works, with a long-reach excavators loading trucks that will drive from site. As was the case last time, the load out of excavated material will continue up until 10pm on nights. As with the underground excavation, the lessons learned from last time will be applied – with all light towers running off mains power and the excavator operators barred from using the bucket on concrete to scrape up loose material.  Loadout from 6pm to 10pm will only be of softer materials with no load-out of concrete segments into truck beds.

In the northern end of the station box underneath the acoustic shed, the team quietly achieved a major milestone on Tuesday with the pour of the first section of the concourse level underneath the acoustic shed. While somewhat overshadowed by the large pour in the south box, this pour is a major milestone as the station infrastructure starts to take shape, as tunnelling winds down.

Thanks, Rob and Jordan
