CYP Weekend work

Info from CYP…

A quick note on some works that are happening this weekend.

Those who came on the tour would have seen the launch ring being set into the wall in preparation for TBM assembly and launch. You may recall John saying that the wall requires a coat of shotcrete to seal and support the steel rings on the southernmost wall of the station box.

Shotcrete is a method of applying concrete at a high velocity to make the concrete self-supporting unlike that of a slab concrete pour which requires formwork to keep the concrete together. These works can only be done when there are no other personnel in the box. As a result, these works are going to take place on Sunday 8 December while the box is empty.

As this is a Sunday, we’re taking every precaution to ensure that the works are as unobtrusive as possible.

  • All concrete pumps will be confined to inside the acoustic shed
  • All concrete trucks servicing the pumps will park inside the shed (a total of seven trucks will be used between 7.30am and 7.30pm)
  • We’ve established a truck route that will not require reversing into the shed. The only reversing will occur inside the shed to back up to the concrete pump
  • A smaller concrete pump will be used.

In other TBM news, The next deliveries for TBM Millie have also been scheduled. These are still subject to confirmation by Yarra Trams. The oversized loads are expected to come in on trucks over two nights – after 1am on the 16th and 17th of December.

Unlike the previous loads that drove into site and parked for unloading in the morning, the trucks required for delivering these parts will need to be unloaded by crane on arrival, as it is too big to park up on site.
