Geotechnical Advances and Challenges in Urban Development

2020 AGS Sydney Golden Symposium

Prof Robert Mair, Dr Chris Haberfield, Paul Hewitt, Idy Li, Theva Muttuvel, Philippe Vincent, David Lees, Hashan Subasinghe, Helen Baxter-Crawford, Peter Sun, Antonio Ramirez Martinez and Bosco Poon & Rikito Gresswell

The symposium will showcase state-of-the-art practices, new research findings and case histories that demonstrate geotechnical advances and challenges in urban development. The organising committee invites papers on geotechnical aspects of urban development, underground structures, restoration of geotechnical structures, innovative and cost-efficient solutions, groundwater modelling and application of smart technologies. The symposium presents an opportunity for professional engineers, researchers, specialist contractors, regulators, educators and students to meet and share their knowledge and experiences in geotechnical engineering.
