On behalf of the Organizing Committee of 19th World Conference of the Associated Research Centers for the Urban Underground Space – ACUUS 2025, we are pleased to invite you submit a paper for the upcoming ACUUS Conference, which will be held from November 4th to 7th, 2025, in Belgrade, Serbia. The deadline for submitting the abstract is February 1st, 2025. The first call of abstracts can be found HERE.
The Organizing Committee of the ACUUS 2025 BELGRADE Conference has successfully established a significant collaboration with the prestigious journal Tunnelling and Underground Space Technology (TUST) to publish a special issue dedicated to the conference topics under the title: “Underground Mobility and Elevated Thinking: New Opportunities and Challenges in the Use of Underground Urban Space”. More information about the Conditions are available HERE.
This year’s conference theme is “Underground Mobility and Elevated Thinking: New Opportunities and Challenges in the Use of Underground Urban Space” with a special focus on overcoming current obstacles to further the future development of underground spaces. The main conference topics:
- Underground and climate change: Resilience, sustainability and urban transformation
- Overcoming challenges in tunneling and underground design and construction
- Advanced technologies and innovative solutions
- Architecture and planning – underground
- Safety, security and human factors
- Legal, entrepreneurial, and real estate aspects of underground space
- Digitalization and AI toward underground space solutions

The idea that many cities and regions of the world are poised to greatly increase their use of underground space and that there are a variety of modern underground facilities around the world that now have several decades of operating experience led to a study conducted by the Surbana Jurong Group over an approximately 18-month period in 2019 and 2020. The study gathered information from 42 underground facilities from 15 different countries worldwide that had an average lifetime of service of approximately 37 years. The study has allowed the collection of the lessons learned and particular emphasis was placed in the study on whether the decision to build underground was still considered the right one, how the architectural design influenced the human acceptance of the underground spaces created and whether the technical aspects of the facility had performed as expected.
