Please join us in the 18th Conference of the Associated Research Centers for the Urban Underground Space (ACUUS 2023) in Singapore which is also combining the 2nd International Conference on the Exploration and Utilisation of Underground Space (EUUS-2). The EUUS conference series is an ACUUS initiative with a focus on urban geology and underground resources.

The main theme for ACUUS 2023 Singapore is “Underground Space – the Next Frontier.” This theme was chosen to focus on the new opportunities and challenges in underground space use amid a re-focus on exploring and developing the underground space as a strategic resource and part of sustainable development. The new frontier presents unprecedented opportunities for simultaneously improving urban infrastructure, urban livability, and resilience. At the same time, special challenges exist in developing underground space – both from a human design perspective and in terms of complexity, 3D planning, system integration, technical, and life cycle costs. Equally important is the need to move from the creation of underground space as a haphazard, last resort solution to a well-planned, and integrated use of underground space that can serve the needs of society for future generations as well as our own.
