VMT has been providing equipment and site support for the biggest public transport project in Australia.
At the end of April 2020, the final tunnel boring machine (TBM) drive was completed at Blues Point after tunnelling 885 m from Barangaroo, working at a depth of up to 40 m under Sydney Harbour.
Now the project is being extended to cover the city and southwestern districts of Sydney with the current work program involving five TBMs working concurrently across the tunnel route.
Other sections of the tunnelling works – mainly for the cavern construction – involve the use of 13 roadheader machines along with seven rockbolter rigs.
VMT has been supporting the project by providing equipment and site support for the TBMs, roadheaders and rockbolters with a variety of navigation systems.
This includes systems for each of the tunnelling system types as well as its segment documentation system (SDS), as well as support by VMT’s TUnIS Navigation Office software.
Additionally, VMT introduced its TUnIS.mono.cam for the first time, which was specifically designed for the navigation of double shield TBMs.
Being the first use of the new system, Sydney Metro was happy to witness its effectiveness as well as receiving VMT’s overall support.
