Sydney Metro: TUnIS.mono cam in action

+ + +

We are busy all around the globe. And even more so since we made it to Japan.

More than 9000 km away from home, our Ring Convergence Measurement System (RCMS) has been in action beginning of this year in the town of Himeji, being the first VMT solution ever used in Japan. Our client MAEDA uses our RCMS to monitor the segments of a curvy water tunnel project. This 1.3 km long tunnel with a diameter of 3.84 m, will only be the start of our adventures in Japan. And although some translation apps had to be used for the communication in our first outings in Himeji, we already feel home in Japan.

The UK has always been a pioneer in mechanised tunnel construction. Owners as well as construction companies are not only open but are demanding innovative solutions outright.


And “High Speed Two (HS2)” is not only the most important European infrastructure project ongoing but the hot spot for new technologies and product innovations.

That’s why we didn’t only show up with a wide range of our established product solutions, but we also brought along our youngest innovations:

Want to know more about these youngest offsprings? Our colleagues, Jonatan Marcos and Florian Werres will tell you!

IN THE PAST: Quality checks of Master Rings took place on a horizontal surface, with test rings loaded on top of the Master Ring if required.


NOW: Our Virtual Master Ring construction software does the heavy lifting for you. Virtual master rings and trial rings are created & analysed for accuracy/production quality before being transferred underground. This means massive savings in cost, time, and people power.
How does it work?

The new Gotthard road tunnel in Switzerland is considering only using these virtual master rings – a significant step into the future of the segmental lining industry. More information about the Virtual Master Ring process here.

Sydney Metro is Australia’s biggest public transport project: by 2030, the sprawling harbour city will have a network of four metro lines, 46 stations and 113 km of new metro rail.

Having the correct support systems in place for tunnelling machines, information handling and segment liner systems is crucial for such a massive undertaking. TUnIS.mono cam, our assistance system for double shield TBMs, has been involved in Sydney Metro City and Southwest and will also be used for the upcoming projects Sydney Metro West & Western Sydney Airport.

Determining the position of the front shield on a double shield machine has traditionally been a pretty complex undertaking, involving lasers, laser targets, inclinometers and cylinder stroke measurement systems, multiple sensors and complicated cabling. In contrast, TUnIS.mono cam works with only one single active component.
