We are especially proud of the strong international presence – both among the speakers and participants – which added significant depth and value to this year’s event.
This year’s midweek workshop was particularly captivating, offering valuable insights into tunneling construction methods applied in challenging geological and spatial conditions. Thursday’s conference day set a new milestone, hosting the highest number of speakers to date, creating a vibrant environment for in-depth technical discussions. The conference concluded with Friday’s technical excursion to the Karavanke tunnel, allowing participants to explore the progress and unique aspects of this major infrastructure project.
Your passion for research, innovation and sharing expertise has once again contributed to an event that will undoubtedly have a lasting impact on our understanding of tunnels and underground structures. We are grateful that you took the time to join us and share your valuable knowledge.
We hope you enjoyed the inspiring discussions, fresh ideas and meaningful connections with both local and international professionals. We look forward to meeting you again at future events and continuing the exchange of experience and expertise.Upamo, da ste uživali v navdihujočih razpravah, svežih idejah in koristnih stikih z domačimi in tujimi strokovnjaki.
