CYP weekly update – 1 July 2022

Good afternoon everyone,

We hope everyone has had a great week

Below is a snapshot of the works coming up on site next week.

Anzac Station entrance construction – Tram Interchange

Those with a view of the site will have seen that the station canopy team are making great progress on the installation of the cross laminated timber (CLT) panels. The works started in the middle of the canopy and are progressively making their way to the outer edges. Nothing new to report next week, the team will largely be doing much of the same up on the roof. As has been the case for the past few weeks, some work on the canopy will be ongoing after 6pm, but will be wrapped up by 8pm. Tomorrow, elements of the canopy install are also expected to proceed past 1pm, but is not expected to generate significant noise.

Station box construction

Once again, the works down underground remain largely consistent with previous weeks. The crane on surface next to Domain Road is incredibly busy, as everything that needs to go down into the station box is lowered down by one crane. There isn’t a minute of this cranes day that isn’t accounted for. One of the things you may not have noticed being lowered down is the infrastructure that will support the ventilation for the new station. This includes fans and baffles that effectively slow down the air that comes through the station, pushed by the approaching the trains. This air is slowed down and discharged via the stations ventilation on surface. We’ve included a photo of some of this infrastructure that has been installed at the southern end of the station at concourse level. Similar equipment will be installed at the northern section and connected to the ventilation system there.

Surface Works

In the middle of the site there has been some good progress on the delayed pour strips. As you might recall, the delayed pour strips are the final sections of the station roof to be tied into the walls and effectively lock the station box structure in place, before we demolish the D-wall above these sections. Next week we will start the demolition of the sections of D-wall closest to Melbourne Grammar School, we expect that this will continue for the entire the week.

Earlier this year we trialled large custom fitted noise blankets that wrap around the excavator heads to reduce noise, and saw some decent reduction in the decibels. We’ve purchased additional blankets for the larger CYP owned excavators – they arrived this week and are being fitted to the machines, so if you see excavators wrapped in blankets next week, it’s not to protect from the cold – they’re designed to offer some relief from the noise. 

Further to the south, preparation work is well underway for the new temporary diversion road for the southbound lane of St Kilda Road. Next week will see waterproofing of the newly completed delayed pour strip, before we start the backfill and surface preparation commence in this area.  This is likely to also include the use of vibratory rollers on this section, the vibratory rollers have been working in the area this week, however the sections they have been rolling have been pre-existing sections of road that don’t require as much compaction. The sections above the delayed pour strips will require some extra attention.

The construction and commissioning of the new section of road will allow us to continue the delayed pour strip/demolition/backfill works further to the south.  We’re also aiming to get the noise dampening blankets fitted to the Delta excavators that have recently arrived the southern end of the site too. These machines are operated by a subcontractor, but we’re looking to get some attached to their machines also.

Moving up to the northern end of the station, the newest addition to the landscape on site this week has been the pre-cast sections installed in the north of the site adjacent to Albert Road North. As I mentioned in a previous update these pre-cast panels make up the future ventilation system for the station and will be hooked up to the same type of ventilation infrastructure featured in this week’s photo.

Staying in the northern section, works are continuing the relocation works for the High Voltage cable. The team are moving the cable into its new location above the station box. Next Monday there will some work to demolish redundant piles as the trench makes it’s way across the station box and up towards Domain Road. We expect this will only take 2-3 days to break out.
