CV and Abstract of Speakers

Paper 1: The Changi Experience

By Dr Victor Choa

Dr Victor Choa was born in Singapore in 1941. He was a professor in the school of Civil & Environmental Engineering at the Nanyang Technological University of Singapore from 1984 till 2012. He obtained his B.A. and M.A. from the University of Cambridge, M.Sc. from the University of Birmingham and Ph.D. from the National University of Singapore. He qualified as a Chartered Engineer in the Institution of Civil Engineers (UK) in 1968. Between 1964 and 1976, he worked for consulting and contracting firms in the UK. He was involved in highway and bridge construction, slope stability problems, deep excavations as well as deep foundations in projects throughout Europe. From 1976 to 1982, Professor Choa was with the Port of Singapore Authority involved in reclamation and soil improvement for construction of Changi Airport. He joined Nanyang Technological University in 1984 as a professor of civil engineering and previously held the positions of Head of the Geotechnical and Surveying Division and Vice Dean of the School of Civil and Structural Engineering. He was also the Associate Dean of Engineering, Dean of Students, Dean of Admissions, Senior Advisor in the Office of Admissions and Financial Aid and a member of the University Council. Whilst at NTU, Prof Choa continued to be a geotechnical consultant to SPECS Consultants and worked on mega reclamation and soil improvement projects not only in Singapore but also in Malaysia, Indonesia, China and Hong Kong. He has been a geotechnical consultant to many consulting companies and contractors including Maunsells, Ove Arups, Hyundai and Toa Corporation. He has also been a consultant on many World Bank projects. Professor Choa has been active in teaching, research and consulting in the field of geotechnical engineering in general and land reclamation and soil improvement in particular. His research focus is on consolidation of soft soils, dynamic compaction of sand, soil instrumentation and in-situ testing in land reclamation projects. He was also involved in the feasibility of rock caverns for underground space utilisation in Singapore. He has been engaged as a consultant in many international civil engineering projects for port and airport developments including the Tianjin port, Dalian port and Jinan airport in China, Chek Lap Kok airport in Hong Kong and Fiji airport. He has authored over 150 technical papers in geotechnical engineering and four books on land reclamation, vertical drains and rock cavern construction.

This paper reviews the reclamation works carried out at Changi for the airport and other infrastructural developments. Work began around the mid 1970s and was substantially completed in 2005. Different methods of reclamation were used from direct dumping with hopper barges to using cutter suction and trailer suction dredgers . Reclamation materials ranged from ultra soft clays to stiff clays, sand to rock fills. As the area was underlain by deep marine clay deposits soil improvement was required. Prefabricated vertical drains and preloading were mainly utilised and Dynamic Consolidation was also tested. The reclaimed sand was compacted using vibrofloatation, resonance columns, dynamic compaction and vibratory rollers. An area filled with ultra soft clay slurry had to be filled, reclaimed and improved. This area known as the “silt pond” required special relamation techniques of sand spreading and use of geofabrics and vertical drains for soil improvement. The research project utilizing layered sand/clay fill for reclaimation is also reviewed. Generally the paper seeks to share the experience in reclamation and soil improvement gathered from the mega reclamation projects at Changi with the hope that it would stimulate discussion and sharing of experiences with those participants who had been involved in projects of similar nature.

The Supreme Court also received the Outstanding Engineering Award from the Institution of Engineers Singapore.

He was involved in the Gardens by the Bay as the QP for a major part of the infrastructural works. Although this is a

CPG project, he continues as the QP to the completion of the works. He is currently the Managing Director of PH

Consulting Pte Ltd, a licensed corporation under the Professional Engineers Act.

The presentation covers the soil improvement works carried out in Garden by the Bay, using prefabricated vertical drains and the infrastructural design of the Dragonfly Lake and Lion Grove. Garden by the Bay is located in an area that was reclaimed in the 80s, with settlement still on-going. For such a large area, it would not be economical to construct all the infrastructures on deep foundations. Engineering principles are used to mitigate the future settlement of the site, providing safe, sustainable and economic solutions to the project.

Part 1 introduces the shoreline of Singapore before the first major reclamation some 120 years ago, in context with its natural setting. Greater details are provided on the foreshore development that was carried out within the first twenty years of the country’s independence, which set the stage for the development of a world-class seaport and airport. Part 2 discussed the challenges for future foreshore development; it starts with the introduction of the IPCC (Intergovernmental Panel on Climate Change) and the results of its Fourth Assessment Report (AR4). The results of the sea-level rise (SLR) are presented. Post-AR4 results on sea-level rise are then discussed. With reference to Singapore, the impacts of a one-metre SLR are discussed with and without relating to the 1.25 m reclamation level above the highest recorded tide. Future adaptation options to SLR are presented

Paper 5 : Application of Radioisotope Cone Penetrometer for Land Reclamation Projects By Dr. M. Karthikeyan

Dr. M. Karthikeyan has been trained in geotechnical engineering with more than 16 years of research and consultancy experience in the topic of site investigation, seabed characterization, land reclamation, seepage and slope stability. He has published and presented a number of technical papers in International Journals and Conferences.

Dredging works in sea and excavations in urban areas produce large quantities of clay lumps. Use of these clay lumps for land reclamation is an environmental friendly option. The ground formed with this type of recycled fill material is the highly heterogeneous so there is a need to know the state of such ground at different stages of works. This is one of the major challenges as many traditional in-situ tests which provide point values are based on solutions derived with assumption that the ground is a continuum. This paper addresses the in-situ characterization of lumpy fill using Radioisotope Cone Penetrometers, which are capable of measuring the density and water content in addition to usual cone parameters. A series of experimental studies were conducted to investigate and interpret the density profiles obtained by RI Cone. Backscatter and linear mixture theoretical models were adapted and applied to the RI Cone to provide a framework for interpretation of the signatures of wet density profiles. A back analysis of a

set of lumpy fill results obtained from the actual field tests will also be presented.

Development of a 30 mega-ton per annum (Mtpa) coal stockyard area at the Coal Export Terminal 3 (CET3) in

Newcastle, Australia, involved various ground improvement techniques. The project was the largest single-stage coal

terminal development to date.

The site is underlain by soft compressible soil strata of variable thicknesses. To support the 21m high coal stockpiles

and the stacker-reclaimer machinery loads, the upper ground required stabilisation/consolidation improvement.

Liquefaction of the ground during earthquake is also to be addressed as this site is located in an active seismic zone. A

trial embankment was constructed to test the performance of the ground versus predicted movements. Ground

improvement by dynamic replacement (DR) was employed to reduce construction time and omit the need for preload

material. Impact rolling (IR) was used to compact the 4m sand bench on top of the DR-improved ground before

construction of rail embankment.
