Tunnelling Solutions has recently purchased an Akkerman 240A Guided Boring Machine for the installation of large diameter Canopy Tubes for the Norwest Pedestrian Tunnel.   They have also purchased an Electric Butor Tunnel Excavator from Metalliance in France. 

This type of equipment requires extensive training for safe and efficient operation and will also reduce any learning curve on the project.

Tunnelling Solutions recently supplied specialised shotcrete supervisors to John Holland for their Level Crossing Removal Project in Melbourne. 

After several weeks of challenging excavation, Tunnelling Solutions have broken through on the Arncliffe Pedestrian Link in Sydney.

With very poor ground conditions throughout, along with de-clutched canopy tubes under only 2.5m of cover - and trains running above them - the Tunnelling Solutions team did an excellent job in delivering this phase of the project.

The team will now focus on the Permanent Concrete Lining of the Tunnel and Portal Structure.

Northwest Rapid Transit (NRT) has awarded Tunnelling Solutions the contract to build the underground Norwest pedestrian link on the $8.3 billion Sydney Metro Northwest project.

The pedestrian link will be constructed under Norwest Boulevard to provide a second pedestrian entry point to Norwest Station from the retail and business precincts.

The team at Tunnelling Solutions are excited to be a part of this project and are well equipped to provide first class technical input to this challenging work.

Existing cable anchors and rock support need to be removed from the alignment of the tunnel within the station box prior to the team installing 15, 40m long canopy tubes which are 350mm in diameter.  The shaft and tunnel will be excavated and lined using permanent shotcrete with a spray on waterproof membrane sandwiched within the tunnel lining.

 

The Tunnelling Solutions team are looking forward to working with the NRT team to deliver this section of the project.

Tunnelling Solutions completed the excavation and permanent lining of the Arncliffe Pedestrian Tunnel on time and without incident.

When you speak to some, they say site safety has been taken too far and it is now not workable.  This is absolutely not the case, as progress made over the last decade in keeping people safe has been outstanding.
