This Annual Seminar places the emphasis on the geotechnical engineering aspects on infrastructure developments. Infrastructural developments are essential to the success of any international world class cities, such as Hong Kong. The average daily patronage of our rail system is nearly 5 million and more than 600,000 people are crossing the border each day. Every day, we open our tap to get safe and portable water and we all take it for granted. Infrastructure development in Hong Kong has evolved to meet the changing demands of society. The 1950s-1960s focused on basic needs in water supply and public housing. Expansion of new towns and the railway network accelerated in the 1970s-1980s. The 1990s heralded the airport and port strategy, while the 2000’s brought greater cross-border connectivity. 2010s brought a focus on driving enhanced economic competitiveness and improving living environments. The recent era of infrastructure development, including the Ten Major Infrastructure Projects, further enhanced Hong Kong’s transport network, urban environment and the quality of life of the population. The HKIE Geotechnical Division Annual Seminar provides a platform for engineers to share and document their experiences working on infrastructure projects in Hong Kong and overseas. The seminar is divided in four sessions on different category of infrastructural projects, each with selected presentations. We are particularly grateful to Ir Kevin Poole of delivering a keynote lecture on the airport development and Ir Neil Ng, on the construction challenges of the Sha Tin to Central Link.
