Singapore first played host to ACUUS in 2012 at the 13th World ACUUS Conference.  It was a very sucessful meeting and we attracted participants from 35 countries and received 150 over submissions.

The committees for ACUUS 2023 has planned a very exciting and extensive programme which will feature technical sessions with invited world-renowned keynote speakers over 3 days. Pre-conference workshops and training courses are also incorporated into the programme. We are happy to announce that the second EUUS conference will be co-located with ACUUS 2023. This will feature urban geology and urban geophysics in the overall programme. In collaboration with Shanghai Municipal Engineering Design Institute (Group) Co Ltd (SMEDI), the "Shanghai Declaration" will be signed during this conference.


The combined conference will be presented as a hybrid attendance format with the possibility of satellite on-site sessions in other countries outside of Singapore.   ​

Shanghai Declaration Activities
On the occasion of the 4th Anniversary of the Shanghai Declaration signed in Dec 2019, ACUUS and its key partners, UN-HABITAT and the Science and Technology Committee of the Shanghai Housing and Urban Rural Development Committee, are planning a series of activities to celebrate our achievements, take stock, and recommit our pledge to promoting the use of underground space for sustainable urban development. Details of the activities will be announced soon. The attached documents show the Shanghai Declaration signed in 2019, and the Tokyo Declaration signed in 1991.

Technical Visits & Learning Journeys

Apart from "sedentary" conference presentations, Technical Visits and Learning Journeys will be organised during and post-conference. 

Exhibition Showcase

To offer networking opportunities during the conference, we will host an exhibition showcase hall where all attendees and exhibitors can socialise in a relaxed setting.

Social Programme

Not forgetting the accompanying persons who travel to Singapore with delegates of this conference, you will find that Singapore is a hive of activities that you can enjoy.  There is something for everyone, from the young at heart to the adventurous.  Singapore is a stone's throw away from Malaysia, Thailand, Indonesia, Vietnam, Cambodia etc.  Come make Singapore your "stepping stone" as you explore the South-East Asia either before or after ACUUS 2023. 

Watch this space for regular updates to the programme which will be announced from time to time.
