Good afternoon everyone,
We hope you’ve been keeping well.
We are writing today with our next weekly construction lookahead.
Anzac Station entrance construction – Tram Interchange
A lot of progress has been made this week in the tram interchange, most notably the feature stairs have been poured at the northern end of the oculus, and the escalators have been installed at the southern end.
Next week, steelfixing will continue on the pedestrian bridges over the oculus. Steelfixing in this area will continue until 10pm on work nights until the bridges are poured, which is currently scheduled for Tuesday.
Next week, work will continue to strip the formwork from the feature stairs, as will the installation of glazing on the lifts.
Set up for the canopy columns will also begin next week, with the first of the installation scheduled for late next week.
Station box construction
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.
Today, we’ve included a picture at platform level looking south. In this image you can see on the left the first of the platform installed. On the right, you can see the over track exhaust system being installed, with the steel framework for the platform doors in front.
Platform screen doors will be installed at each of the five new stations on the project. You can see a quick explainer on them via the link below:
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, as well as formwork and steelfixing for the delayed strip pour.
