Here you can see our project engineers Viktor Marzinkowski and Vadym Tiroshko setting up MODUS connect and prisms on both sides of the sleepers.
Great to be part of the Seraing Sowaer microtunnelling project with our partners NMBS-SNCB and K-Boringen nv!
Find out more about MODUS here.
They’ll arrive in Sydney in just 5-7 days where they’ll be installed and commissioned by our Australian colleagues…and within a few short weeks they’ll be ready to go on the Roadheaders and Rockbolters which are digging the WestConnex 3A and 3B tunnels. Happy travels!
PS. How great is our Material Logistics team?! These guys handle around 1,000 of these shipments per year, making sure our products arrive intact and on time at construction sites all over the world.
Congratulations and a huge thanks to our long-standing partner and customer Ward and Burke Construction Limited, who gave us the opportunity to extensively test the endurance of our new generation system TUnIS Navigation MT – in combination with the new hardware platform MT connect – throughout the project.
Martin Betsch, Microtunnelling Surveyor at Ward & Burke, was particularly taken with the WLAN network, stating: “The reliable WLAN that VMT’s new MT connect platform provides in the tunnel is a real advantage that not only simplifies the use of the navigation system, but also provides great support and time savings during repair and maintenance work in the tunnel”.

The new railway line will comprise 47 km of tunnels, have over 100 bridges and 23 modern railway stations and stops along the route. The project is being hailed as one of the most important transport infrastructure projects currently underway in Europe. The construction of the project is due to be completed by 2023 with the route being fully operational by 2025.
The Koralmtunnel KAT3 construction lot recently broke through completing the last of Koralm Tunnel drives in St. Paul im Lavanttal, Carinthia, Austria. A Herrenknecht 9.94 m diameter Multi-mode TBM was used. This type of machine has the capacity to operate in both EBP and open modes to cope with changing ground conditions along the drive. This particular length of tunnelling work covered the final 10.474 km of the tunnel and included a curve with a minimum radius of 3,000 m. The drive commenced in October 2015 and was recently finish on the 17th of June 2020.
The multi-mode design of the TBM was necessary because for about the first 4 km of the drive the TBM drove through sedimentary rocks of the Neogene period and through the Laventtal main fault zone in EPB mode. In June 2018, after two months of conversion work, the TBM started driving the remaining 6 km (approximately) in the open hard rock mode.
The construction site is owned and managed by major infrastructure contractor PORR which has had a long-term relationship with both Herrenknecht and VMT in connection with other tunnelling projects.
To support tunnelling, VMT supplied the necessary navigation and other site management systems including TUnIS Navigation TBMLaser system alongside TUnIS Navigation Office software, VMT’s TUnIS Ring Sequencing system, SLuM Ultra (VMT’s Automatic Tailskin Clearance Measurement System) and VMT’s RCMS (Ring Convergence Measurement System). The VMT systems were purchased as part of the TBM contract and mainly installed during the machine build. The RCMS system was installed later during the course of 2019.
VMT engineers also provided on-site training for project staff during the course of the project as well as the purchasing of spare parts when required for the navigation system.
The site team also worked with the VMT team to site test various other VMT products which included the new central box LDT.connect and the ELS3G target unit.
Testimonial Statement from Joachim Geißbauer, site manager for KAT3
“Koralm Tunnel Construction Stage KAT3: 10,500 m through most difficult geology
The Koralm railway is part of the new southern railway line. The heart of this new line is the approximately 33 km long Koralm tunnel which connects the two provinces of Carinthia and Styria.
The Koralm tunnel is being built in three construction stages. The third and last construction stage KAT3 extends over a length of around 12 km and will be driven in the north tunnel, for the most part with a tunnel boring machine. The Koralm tunnel crosses the massive Koralpe mountain range with a maximum overburden of about 1,200 m. The two tunnels run with a centre distance of around 40 m and are connected to each other every 500 m by cross-sections. Due to the project length at the KAT3 construction stage of about 11 km, it was necessary to efficiently connect and evaluate the data from segment production, the tunnelling (TBM data) and the surveying work as well as the results of the geological and geotechnical monitoring.
With the support of VMT GmbH and its products, the machine and survey data could be collected and merged.
Furthermore, in geologically challenging areas, the RCMS convergence measurement system was able to produce a condensed record of the ring convergences, which was also linked to the existing survey data from the tunnelling.
- Thanks to good cooperation between an experienced customer and experienced service experts from VMT, the challenging drive was masterfully executed through to the final breakthrough
- Due to the long construction period of about 5 years, it was periodically necessary to overhaul the systems used or to adapt them to changing specifications. The employees of VMT GmbH always completed this task to the utmost satisfaction
- Thanks to VMT’s service support, all the client’s key requirements were met and the tunnelling work was completed successfully”
