CYP weekly update

Good evening all,

We hope everyone has had a great week.

Below is a wrap-up of construction activities happening on-site next week, noting that there will be some nightworks on Tuesday and Wednesday undertaking road resurfacing and realigning the southbound lane of St Kilda Road. Works will begin on Tuesday 26 July, with Monday being an RDO.

Surface Works

Over the past two weeks, the team have been preparing a new section of road within our site. This is to prepare for next week’s new alignment of the southbound lane on St Kilda Road. This weekend, works will continue finishing road surfaces within site, applying granular layers and asphalt with a vibratory roller. Some of these road works within site may continue this Saturday to 4pm in order to get ready for the road switch mid-week.

On Tuesday 26 August and Wednesday 27 August, between 8pm-5am, overnight works will complete the tie in points of this section with St Kilda Road. Overnight works will include moving concrete barriers and applying asphalt at the tie in points on Tuesday night. Finishing works including line marking will recommence on Wednesday night the new alignment of the southbound lane in place from 5am Thursday morning.

Traffic management will begin setting up on Tuesday and Wednesday at 8pm with southbound lane road detours in place by 9pm. Wednesday traffic will run on the current alignment. The attached notification for these works indicates the southbound lane detour via Kings Way that will be in place during these overnight works.

Other surface works to be undertaken over the next week include demolition of the D-wall north of this area. The team will be trialling the use of a wire saw to cut sections of D-wall where there are no services behind the wall. This will reduce the amount of jackhammering required.

East of the oculus we will be waterproofing and backfilling down the centre of site.  Excavating, backfilling and waterproofing will also continue in the north-west section of site.

You will have noticed that site sheds have been removed over the past week in the northern end of site where drainage and road works will begin to prepare for another realignment of St Kilda Road’s southbound lane in September. Some minor pedestrian detours may be in place over the next two months where these sheds have been removed with further information to be provided as these works progress.

Sunday Works

CitiPower have advised us that they will be carrying out works this Sunday on the high voltage connection points at the pedestrian crossing at Domain Road. CitiPower operate under a separate permit to the Metro Tunnel works and as a result are subject to different standard working hours (as is the case with all utility companies)  Citipower will be undertaking works within the Domain precinct at the Shrine of Remembrance, Domain Road and Park Street and will also provide separate notification of their works occurring over the next month.

We’ll keep everyone updated on works outside the normal construction hours as we are informed of their works.

Anzac Station entrance construction – Tram Interchange

On the platform station canopy, skylights will be installed over the next two weeks, beginning next Tuesday. The team will use basic hand tools and a scissor lift to install and, with some potential wet weather in line for next week, may include some out of hours works until 6pm weekdays and Saturday until 5pm. This work is not expected to generate a lot of noise.

Installation of wet fire services continues with installation of the fascia around the canopy starting next week. The Tram Interchange platform kiosk takes further shape with two external façade panels and roofing being installed next week to reveal the full footprint of the kiosk.

Station box construction

Within the lower levels of the station box the B1 level fit out and room build is on-going with the roughing in of services. The substation for the northern HV rooms will be arriving in the next 2 weeks which will be lowered in through the void from surface level. In surrounding service and operational rooms, more doors and finishing surfaces will be installed with layers of sealant and paint applied to these areas.

Down on B2 the core stairs have been installed with more insulation, cladding and ducting being installed in the southern end around attenuators over the coming week.

That very attractive “kiosk”

A number of you have asked about this new building that has appeared in the middle of the road.

It is a kiosk (city end) plus two toilets for Yarra Tram drivers. It will get a roof and then cladding on the outside. It will be the southern end of the tram platform and will therefore be surrounded by the actual platform.

Before long you won’t end notice it 😉

CYP Weekly update

Good afternoon all,

We hope everyone has had a great week – and on behalf of the French contingent working on the project – happy Bastille Day for yesterday!

Below is a snapshot of the works coming up on site next week, there are quite a few things going on next week.

Anzac Station entrance construction – Tram Interchange

As we mentioned last week, the installation of the wet fire services began this week and there are now lengths of metal piping running along the top to support the fire systems for the new station canopy. Preparations for the skylights have begun and we’ll likely see some installation works commence next week. On Saturday the team will be working a little longer on the canopy – but all works will be wrapped up before 3pm and is not expected to generate a lot of noise.

Normally we include the kiosk construction in the surface works component, but as the kiosk progresses it will form part of the final tram platform structure, so we’ve moved it to the tram interchange section. The pre-cast panels that form part of the kiosk have been in place for some time, and recently the team installed conduits and then completed a series of concrete pours around the base. Monday next week will see the arrival of additional sections of precast for installation – and the shape of the kiosk structure will start to become evident.

While we the canopy construction at Anzac Station progressing every day, it has gathered a lot of interest as it starts to take shape on St Kilda Road. On Wednesday, Channel 9 came out for an exclusive look at the structure and it featured on the evening news bulletin that night.

Station box construction

Down at the northern end of the concourse, it continues to be a hive of activity with the myriad of back of house rooms coming together with block work, roughing in of services and in some areas the start of first coats of sealant and paint. At the southern end works are far more progressed as the back of house area here sees some floors getting their first epoxy coating and the rough in of the lighting in others.

If you walked down to the platform level you can now stand on the future train platform, as the pre-cast sections of concrete continue to be installed from south to north. We’ve included a photo this week standing on top of the platform. A few things to note in the picture – If you look at the nearest pillar, you can see a groove at the bottom – this is final level that the topping slab of concrete and tiling for the finished station platform will come up to. Also in the top right of the photo you can see some steel structures hanging from the ceiling, these are the structures that will support the future platform screen doors.

Surface Works

You may have noticed in the most recent construction notification, there is a new section of road shown in the precinct map (we’ve included this same map in this week’s update) This is the road that we’re constructing right now in the southern section of site

The southern-most exposed section of the roof slab has now been waterproofed and the first layer of backfill applied. Next week this section will begin to actually resemble a road, with additional backfill and pavement works commencing.

Later this month we’ll be switching south bound traffic onto this section. We will have some night works to complete as we do the last bits of asphalting to tie this road into the existing lane – we’ll send around a separate construction notice when we’ve confirmed dates (and as always, we’ll keep you updated via this email)

Moving closer to the station canopy in section 2, we’ve just this week broken down the last of the D-wall closest to Melbourne Grammar School, next week we’ll start clean out this area and later in the week commence backfill closest to the wall.

While up in the northern end of the site, the high voltage (HV) works are continuing, which involve trenching and laying of conduit.

As I mentioned last week, CitiPower will be coming to site to do some of the works to tie their assets back into their network. These works are done under CitiPower’s own works permit – so they are carried out separately and notified separately – I’ve included a copy of their notification to this email.  We’re obviously working closely with them on these works. You’ll see in their notice that there are works on the Shrine side near the pedestrian crossing at Park Street.  There may be some pedestrian delays as they work in this area, but generally pedestrians will be able to get around their works. They’re also working at the pedestrian crossing over near Domain Road – we’re not expecting any pedestrian impacts here.

The works on Park Street have been pushed back until the 1st week of August. We’re expecting that these may be a little more disruptive, with the left turn from St Kilda Road into Park Street closed – and a pedestrian detour required during excavation. We’ll have some more detailed information about these works in next week’s update – and we’ll be sending out a specific construction notification to go with it.

One of the more prominent changes to site next week will be the removal of the site sheds nearest to the St Kilda Road tram stop at Park Street. Next week we’ll start removing these in preparation for some road works through this area, in some areas we’ll need to drop in concrete jersey barriers to fence off the site.

CYP weekly update – July 9

Good evening everyone,

Wrapping up after a fairly wet afternoon, below is a round-up of the activities happening on site next week.

Works will begin on Tuesday, with Monday 11 July being an RDO on site.

Anzac Station entrance construction – Tram Interchange

You may have noticed that the canopy of the new tram interchange platform has been making great progress with the last panels of cross laminated timber (CLT) being applied yesterday. Installation of the wet fire services (essentially the fire sprinklers) are continuing next week with the assembly and installation of the skylights beginning next week.

Over the next week, the team will also begin the installation of the roof cladding.

Station box construction

Mechanical services and electrical works will be ongoing in the concourse level of the station box, with a delivery of large doors arriving over the next two weeks to be installed in the various services rooms.

Down on platform level, installation of the precast platform segments continue, with the first pour of the integrated topping slab occurring above these precast platform planks.

Next week, the team will be pouring the final set of the fire escape stairs which will connect the platform to the concourse level.

It’s been out of sight, out of mind for a while now – but there is plenty of working being carried out in the tunnels with the team busy fitting out the tunnel with everything required to run trains in the future. This week we’ve included a photo from out at the Eastern Portal in South Yarra – with the tunnel stretching out ahead towards Anzac Station. Specialised gantries are progressively rolling their way towards Anzac Station and onwards to Town Hall Station. These gantries provided the elevated working platform that allow the workforce to affix the various cable trays, brackets and pipes to the wall of the tunnel.

Surface Works

In the southern area, sections of the D-wall will continue to be broken out. As we mentioned last week, the noise reducing shrouds will be fitted to the hydraulic hammers that have this option available.

In the lead up to the realignment of the southbound lane of St Kilda Road, the team are preparing the new section of road with compaction of backfill, crushed rock and granular layers.

Backfill and waterproofing continues on the southern section of the roof slab where previous removal of the diaphragm wall has occurred. Further layers of backfill will be applied over the coming week.

Steel fixings and concrete pouring of the Kiosk structure’s base slab will begin next week with three more pours to follow, this will begin to give shape to the final kiosk structure.

Up in the northern end of the site, you will see the high voltage (HV) works continuing, which involve trenching and laying of conduit. These works are in preparation for the final connection, this work will be carried out by the utility asset owners CitiPower in the next few weeks.

Electric vehicles (EVs) and fires

When I first talked ab out charging EV’s, a few people asked about fire risks.

We checked with our insurers and they told us they the risk of fire does not increase with EV charging – so long as it is done by a licensed electrician.

I’ve seen recent info that suggests that buildings that have no EV charging infrastructure have increased risk of fires…HUH?? The claim was that if the building has no proper infrastructure then people run cables and power boards all over the place. A bit of a long bow but probably right.

Recently I personally took my EV to an SES / CFA workshop so that emergency workers can see the new generation of EVs.

They pointed out this site that they use and it has lots of great info on EV’s and fires. Basically low risk but different info for people to learn.

Lots of info here

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.
