We had an amazing evening at our Technical Seminar on GEO Publication No. 1/2023 (Deep Excavation Design and Construction) on 20 Oct 2023! With immense pleasure, we would like to share that we had a staggering turnout of 335 participants joining us online and around 80 attendees who joined us in person. This seminar provided valuable insights into the latest developments in deep excavation design and construction, including enhancement in limit state dea of groundwater level for design, ground deformation control mechanisms and novel construction technologies, etc. We would like to give special thanks to our guest speakers Ir Dr Raymond Koo and Ir Sammy Cheung from the Geotechnical Engineering Office. By attending this seminar, participants gained in-depth knowledge about the GEO Publication, enabling them to achieve economic design of ELS works and potential savings in construction time. Thank you to all the participants and the organisers who made this event a tremendous success, and special thanks to Ir Carmen Lau for handling all the enquiries at the back. Stay tuned for more exciting events in the future!
