Regional Director, Bauer Southeast Asia Pacific
The Governments of the PRC and the Hong Kong Special Administrative Region of the PRC are in the process to build a fast lane connection between Hong Kong and the Mainland China / Zhuhai and Macau. Two key projects for this connection are the Hong Kong Boundary Crossing Facilities (HKBCF) and the Hong Kong Zhuhai Macau Bridge (HZMB). The HKBCF will serve as a transportation hub and provide clearance facilities for goods and passengers using the HZMB. The HKBCF will be placed on a man built island with a size of about 130 hectares. The reclamation site is located in the open waters close to the Hong Kong International Airport (HKIA). The Hong HZMB is a mega-size sea crossing with a total length in excess of 40 km.
SUMMARY
The presentation intended to show methods and technical possibilities available in the market to improve soft ground offshore and construct large diameter Bored Piles efficiently offshore by referring to 2 Mega Projects presently under construction in the Hong Kong Zhuhai Corridor. The methods described are the Bauer RKD Method and the Bauer Betterground offshore Stone Columns. Both construction techniques deliver high quality products econimically by minimizing construction time. It is the first time that Bauer RKD Method is being used for Mega Offshore Project worldwide. Upon completion of the projects final conclusions will be drawn but the present experiences on site are all positive. The overall convincing performances surely still can be improved by all parties involved learning from each other to understand the needs and further optimize the entire process to fully gain the most out of the method. A short view on liquification awarness was offered in the light of the specific relevance for Indonesia.
