The Parallel Technical Sessions form the core of the ITA World Tunnel Congress technical program, providing a platform to present and discuss the latest research, projects, and innovations in tunnelling and underground space development. Organised across multiple thematic tracks, these sessions allow participants to choose detailed topics that best fit their professional interests and expertise. 

Covering a wide range of subjects—from design and construction techniques to sustainability, safety, digitalisation and contractual practices—the sessions encourage in-depth exchange of knowledge and foster collaboration among industry professionals worldwide.

To maximise direct engagement and knowledge sharing, the program will emphasise a dynamic oral format, featuring both long and short presentations and workshops. This year’s congress prioritises these verbal exchanges across all thematic tracks in lieu of a traditional poster gallery, ensuring every selected work has a dedicated moment for audience interaction.
