The round one is an inlet – It brings in outside air to the mechanical systems, so nothing will be discharged from it.
The middle one is an outlet – It is the over track exhaust, but also has battery/uninterruptable power supply (UPS) room exhaust in the event they are called on. During normal operations, the over track exhaust extracts heat locally from the air conditioner condensers which are onboard the train and braking devices of the stationary trains. In the unlikely event of a fire, this would be used to extract smoke from the trackway, platform and concourse.
The tall one is a tunnel ventilation system (TVS) inlet exhaust –The TVS shaft can either exhaust or supply depending on the requirements of the tunnel (two shafts – one supply and one exhaust). The TVS is an environmental control e.g provide fresh air within tunnel and discharges oncoming air from approaching trains. In the unlikely event of a fire, the TVS is designed to prevent smoke spreading and to maintain acceptable conditions in the non-incident tunnel.
Apologies for the delayed look ahead. It appears this didn’t send properly on Friday afternoon – with any luck this one arrives in your inboxes.
There has been a lot of change out on site recently with the site now divided by the new section of southbound lane of St Kilda Road. This has allowed the us to shift our barriers onto what was the previous southbound lane and begin to breakout the old traffic lane to lay new tram tracks and lay the new road alignment adjacent to these tracks. Thankyou to everyone for you patience as we tied in the new section of the road, the significant amount of rain did not help matters, but the new lane is now open and we’re pushing ahead.
Next week will see a number of key activities run up until 10pm – During the week just gone, we wrapped up activities at 8pm, but the weather is not looking kind, and it is more than likely that these will need to continue all the way until 10pm.
Anzac Station entrance construction – Tram Interchange
The footprint of the new tram interchange will begin to expand significantly over the next few weeks as the team begin to pour the concrete foundations of the platform itself. The platform extends from just near the top of Albert Road, all the way down beyond the new kiosk that has been constructed and is now in the process of being fitted out. The team are also getting up underneath the canopy to get some works done on the underside of the canopy, while at ground level, the first sections of glass for the balustrades around the oculus began to be installed this week and will continue into next week.
Next week will also see more progress on the kiosk, with the glass installed for the future kiosk and the installation off some of the cladding around the outside of the kiosk.
Some of these works will continue out to 10pm including works on the underside of the canopy and the installation of the new cladding on the kiosk.
Surface Works
Outside the platform, the new sections of tram tracks continue their progress through site on the eastern side. Now that we’ve taken the old southbound lane of St Kilda Road and made some room on the western side of the canopy, you’ll start to see more tram track work in this section as well as installation of the new tram poles. We are quickly approaching the deadline of the 27 November, when we switch off the power to the tram lines, buses replace trams and we begin the 24/7 works to break out the existing tracks and realign them to connect in with the new sections of tram alignment around the new platform. Like this week, next week some activities will extend out to 10pm to ensure we are ready for the 27 November. The platform and new sections of track need to be ready for this critical date, so over the coming weeks more activities will extend out to 10pm. Activities you’ll see on site next week are similar to those you’ve seen to date, with excavators doing earthworks, tram track laying, asphalting, concrete pours.
The ventilation shafts will also continue to get some attention next week, the concrete pours continuing for the northern shafts are complete, connecting them to the station roof. We’ll see same at the southern end next week before waterproofing and backfill commences on both.
Station box construction
The big development inside the station box is the start of the construction of the stairs from concourse level down to platform level. The frame for the future pedestrian elevator has also been installed. We’ve included a photo this week on the first section of the formwork for the new stairs.
Shrine Entrance
Next week at the Shrine entrance over near Domain Road will see the start of the steel fixing for the new section of roof. Once the roof is installed, the main excavation down to the future base slab will commence.
There are some orange poles out the front that mark the divide between the tram tracks and the road. Some days I go out and see that a few are missing or strewn about.
I’ve sometimes wondered how it happens – now I know
BOWEN CRESENT/ QUEENS LANE INTERSECTION TO ST KILDA ROAD/ BOWENS CRESENT INTERSECTION.
Date: 24/10/2022 – 25/10/2022
You are advised that the associated building works need to occur on with a dry run involving a crane set up on 24/10/2022 – 25/10/2022 from 7am till 7pm and as such this notice serves as information of the likely impact of this activity.
These works are a component of the refurbishment at 412 St Kilda Road. The works involve the use of a mobile crane operating from 7am – 7pm and will result in a full road closure. The machinery will operate for 2 days.
In case of inclement weather or delays, if we are not able to set up up on these dates the set up may occur on 26/10/2022 and 27/10/2022
Although the works are substantial, every very effort will be made to minimize impact to businesses and the general public. The following treatments will apply:
• Pedestrian access will be maintained via opposite footpath(s)
• Access to building car parks are to be maintained
• Access to all properties will be maintained.
The refurbishment works for this site was never going to be an easy task however, the contractor will attempt to minimize the impact of these building works and apologises for any inconvenience that may be caused.
Although the works will be difficult for local traders and residents, your co-operation will be greatly appreciated.
We hope everyone has been staying dry and taking care with the recent weather over the past week.
Due to this inclement weather, some of our works have been rescheduled resulting in some out of hours work required this weekend and next week.
This evening, works will continue within our worksite until 10pm to align barriers along the future alignment of St Kilda Road’s southbound lane.
The overnight road works to switch over to this new southbound lane will now occur Monday 17 October from 8pm until 5am Tuesday 18 October with the new alignment of the southbound lane in operation Tuesday morning, weather permitting. These over-night works will mainly involve line-marking the tie in points to the new sections of road and shifting site perimeter concrete barriers.
On Saturday, some works may continue until 6pm undertaking roadworks within site in preparation for this switch as well.
As mentioned in our monthly construction update, this Tuesday evening, from 7pm, 18 October until 2am, 19 October, soil sampling works will occur alongside St Kilda Road’s northbound lane at the intersection of Kings Way and St Kilda Road.
This will require the temporary removal of six carparks near the corner of St Kilda Road and Kings Way and require the temporary closure of the left-hand turning lane into Kings Way. Vehicles travelling northbound will still be able to turn left into Kings Way from St Kilda Road via the northbound through lane on St Kilda Road.
Anzac Station entrance construction – Tram Interchange
As higher winds this week impacted our ability to undertake works on the canopy roof and surrounding area, some works around the canopy and platform next week will continue until 10pm.
These works will include connecting electrical services, utilities, and communications to the platform, installing fascia around the roof and under-flashing to the skylights.
Below the canopy at platform level, glass balustrades will continue to be installed around the perimeter of the central oculus that mezzanines over the underground station.
Cladding will be installed to the underside of the canopy at each end and concrete pouring will begin to prepare for pavers to be installed.
Station box construction
On B2, blockwork is continuing in the northern end of the station box and concrete pours continue.
Installation of steel frames continue for lifts one and two, services installation continues at under platform level and platform screen door steel installation will continue along the platform.
Formwork and steel supports will be installed next week to form up the risers around staircase four with concrete pours occurring over the next two weeks to develop this central staircase.
Shrine Entrance
Despite weather delays, steady progress has been maintained in this location with blinding for the roof slab and steel fixing for the top-down roof continuing next week.
Next week, pile breakback will continue in preparation for the capping beams and main excavation to follow.
Surface Works
The crane that has been lifting the southern ventilation and services shafts into place over the past week was demobilised today in the south.
Over the next week, stitch pours to their base will continue, followed by waterproofing and backfilling to these structures.
Throughout site, from the north to the south, roadworks will continue with asphalting, line-marking and barrier installation continuing in preparation for the switch of the Southbound lane to it’s realigned position on Tuesday morning.
Also through site, the team will progressively lay sleepers and measures of tram track that will form the new tram alignment. Attached is an image of some of the track progress on a particularly nice day this week.
