CYP – week ahead

Good afternoon everyone,

We hope you’ve been having a lovely week.

We are writing today with our next weekly construction lookahead.

Next week will be a shorter week than usual with the Easter long weekend. Works will stop on Thursday, with some works to decommission the large crane commencing from the following Tuesday. We will provide an update on the crane works next Thursday.

Anzac Station entrance construction – Tram Interchange

All eight of the station canopy legs that are connected to the pedestals at concourse level have now been installed in the oculus. After Easter, the four remaining legs will be installed.

This week, the first of the timber rafters and steel spline beams have been delivered to site, with the first of their installation underway. This work will continue next week.

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.

Today we’ve included a photo of the progress of the platform construction down at the base of the station box. The team are making good progress as they construct the platform from south to north. Once the full platform is constructed, a capping slab of concrete is poured.

Surface Works

Surface breakout at the northern and middle sections of site have 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 and screeding in the area will continue. Non-Destructive-Digging trucks – also known as sucker trucks –  will be used on site to clean out any debris in the strip of reinforced steel prior to concrete being poured in the sections of delayed pour strip.
