Professor Tan Siew Ann was a Colombo Plan Scholar who graduated from Auckland University with First Class Honors B.Eng. in 1977 as the top engineering graduate of the school. He joined NUS as a Senior Tutor and earned his M.Eng. in 1982. His M.Eng. thesis research topic is in the Geotechnical area on the excess pore pressure behavior of marine clay in reclaimed land. He was awarded the NUS Overseas Graduate Scholarship to pursue his M.Sc. and Ph.D. degrees in geotechnical engineering at the University of California at Berkeley, which he completed 1982 and 1985, respectively. He has been a staff member of the Department of Civil Engineering at the National University of Singapore (NUS) since May 1980. He retired from NUS end of June 2020. He is now an Honorary Fellow of NUS Engineering faculty.
He had served on the editorial board of “Geotextiles and Geomembranes”, of the International Society of Geosynthetics, and the Journal of “Geotechnical Engineering” of the South East Asian Geotechnical Society since 1997. He also serves as reviewer of several Geotechnical journals and Conferences over the past three decades. He has published over 300 technical papers covering topics such as Numerical Geotechnics for Deep Excavations, Pile Foundations, Geosynthetics, Ground Improvement of Soft Clays, and Land Reclamation challenges.
He has served as a committee member of several technical committees, including the US Transportation Research Board committee A2K06 on subsurface drainage in highway pavements, TC-09 Technical Committee on Earth Reinforcement for the International Society of Soil Mechanics and Geotechnical Engineering, SPRING Singapore technical assessor on geotechnical testing and site investigations, SPRING committee on earthworks and geotechnical engineering. Prof Tan had served as Chairman of TR26 the Technical Reference for Deep Excavation Works in Singapore from 2005 to 2010.
Prof Tan has been an expert user of Plaxis since 1992. He was actively involved in teaching Advanced Plaxis courses in industry since 2000. He has taught the use of Plaxis in Singapore, Malaysia, Korea, India, Thailand, Hong Kong, Australia and the Netherlands over the last 20 years. He was the course leader for the 1st Asian Experienced Users Plaxis course held in Singapore in August 2003, and again in Thailand in April 2006. He serves on the Scientific Network committee for the Plaxis code development, training and applications since 2002. He is now part of Bentley academy for advancing education in Computational Geotechnics in the Australia Asian region.
He is a registered professional engineer, since 1992, and a specialist Geotechnical engineer in Singapore since 2008 when it was first created after the Nicoll Highway incident. He has been involved in several major consulting jobs in Singapore and the region. His acted as leader of the State “Expert Witness Team” comprising of four international experts in the COI (Committee of Inquiry) for the Nicoll Highway tunnel collapse incident of 20th April 2004. He also served as the State Expert Witness for the No.3 Church Street 31-storey Tower pile foundation excessive settlements case.
Prof Tan also served on the GeoSS-BCA Working Group for the implementation of EC7 for Ground Investigations and Pile Foundations in Jan 2015. He was one of the Keynote Speaker for the GeoSS-BCA Seminar on Deep Foundations on 24 April 2015, focusing on the use of EC7 for pile foundations design.
Prof Harry Tan was awarded the “GeoSS Outstanding Geotechnical Engineer of the year Award in December 2018”, in recognition of his sustained contributions to the geotechnical engineering profession in Singapore, in particular to research, education, and improving the standard of geotechnical practice in Singapore and the region.
On 25 September 2020, Prof Tan was the invited speaker for the “Woh Hup Distinguished Lecture” series at NUS which attracted over 1000 attendees on the Zoom and YouTube platform. His lecture on “Numerical modelling in geotechnical practice (a dream to reality) was very well received by many engineers in Singapore and the region.
On 16 December 2020, his lecture in the “Bentley Webinar on Ground Improvement” on the topic of “Applications of the Concrete Model in recent Singapore projects” was also attended by more than 700 engineers. These attest to the fact that Numerical Geotechnics is now an indispensable tool for modern geotechnical design and practice that requires high level expertise to realistically capture the nature of soil behaviour to optimise on cost-effective engineering.
Though retired, Prof Tan continue to actively teach Graduate Geotechnical modules at NUS CEE Department, and acts as an independent Geotechnical Expert Consultant serving industry in Singapore and the region to do advanced design and value engineering with State-of-the-art knowledge and capabilities to meet the exacting demands and challenges of green engineering that minimise resource consumption impact on our fragile environment.
