Good afternoon everyone,
We hope you’ve been having a lovely week.
We are writing today with our next weekly construction lookahead.
Anzac Station entrance construction – Tram Interchange
If you’ve walked past the site this past week you will have seen that the first of the green canopy legs have been installed in the oculus. Due to their size, the legs are delivered overnight, and then installed during the day. Next week, canopy leg delivery and installation will continue. The first sections of the wooden canopy will also arrive to site next week for installation. We’ve included a picture today of one of the legs being lifted into place by crane.
Station box construction
No change to the works going on underground next week. Precast over track exhaust (OTE) installation continues, along with the framework that will form the platform doors. Installation of the precast sections of the future station platform are underway. The precast segments will be lowered into the station box until 10pm, while preparation works ahead of their installation will continue overnight. This activity is located entirely at platform level, and is unlikely to generate high noise at surface after 10pm.
Internal walls and permanent columns continue to be constructed in the station box, moving from south to north, as well as continuing the construction of the headwall that connects the station box to the tunnels. These works will involve steelfixing, formworking and concrete pours. As with all concrete pours, they must be completed continuously, and may run over normal construction hours.
As per the construction notice, steel fixing will continue in the station box 24/7.
Plunge columns will continue to be removed, as well as firewall shotcreting, heading from south to north in the station box. Works on the plunge columns will continue within the station box until 10pm, and preparation works for the firewall shotcreting will continue on night shift. These activities are unlikely to generate high noise at surface level.
As mentioned in last week’s update, the crane on surface will be required for use up until 10pm on work nights. The void in the south box continues to be closed up – and as a result a smaller crane has been mobilised in the northern section of site and will begin to be used to lower pre-cast segments into the northern void. This northern void will transition to become the main access down into the station box. The larger crane will be demobilised and taken from site prior to the Easter later this month. There will be times when both the large crane and the new smaller crane will be used on surface until 10pm at the same time.
Surface breakout at the northern end of site has been progressing well this week. Below is a detailed run down of works to occur next week.
These works will generate periods of high noise and the works will be carried out during normal working hours.
In addition to the surface works listed below, waterproofing in the area will continue.

Traffic detector loop maintenance – Tuesday 5 April
On Tuesday evening, maintenance work will take place on the detector loop system at the eastbound intersection of Park Street and St Kilda Road. For the duration of these works, Park Street eastbound will be closed between Wells Street and St Kilda Road, with a detour in place via Wells Street and Dorcas Street.
The works are anticipated to take only a few hours, and while most of the works will not be impactful, some concrete sawcutting will be required to expose the detector loop system. This will be completed at the beginning of the works.
We’ve included the notification that was distributed to the area to this email for you for reference.
