The Theme Lecture was held on the 2nd day morning session. There were three presenters covering various applications in the Southeast Asia focusing on coastal engineering.
First speaker Dr. Goh Teik Lim, Managing Director of Atsunew Giken Pte Ltd, covered development history of silent piler and various applications of silent piler in Southeast Asia. He highlighted the construction noise pollution in cities like Hong Kong and Singapore and the beginning of the silent piler in these countries to address the concerns on noise pollution. He then shared the development of various types of the silent over the years with enhanced technologies such as water jetting, supper crush, integral auger, non-staging piling, GRB and zero clearance method for improved performance and efficiency. Several of the case histories shared were works near sea, rivers and reservoirs showcasing the applications for the coastal engineering works.
Second Speaker was Mr. David Liew Wie Sein who is Managing Director of Guan Chuan Engineering Pte Ltd. His presentation titled “Use of GYRO PILER for new applications in Southeast Asia”. He shared that the GYRO PILERTM allows the Earth Retaining and Stabilizing System (ERSS) to be installed efficiently as well as environmentally-friendly, as compared to traditional sheet piles and soldier piles installed using vibration techniques. He further shared that GYRO PILER enables to install tubular piles with cutting bits attached to the piles toe by rotary press-in system, which can cut through existing RC structures or hard rock. It was also reported that GYRO PILER would install faster in hard rock than other traditional methods such as bored pile machines, making it more efficient method.
Third speaker Mr. Tsunenobu Nozaki, General Manager of International Press-in Association, has presented on bracing for rising sea levels – Effective countermeasures using press-in piling method. He highlighted the potential sea level rise in the next 30 years could be more than half a meter and the potential risks in keeping the costal structures safe. He proposed implant structures to upgrade existing dyke structures along the coastal areas as a countermeasure against the rising sea levels. He shared how the press-in pling methods would help to build such implant structures more effectively.
