Bauer Spezialtiefbau involved in construction of Hong Kong-Macao-Zuhai Bridge

Hong Kong – The special foundation subsidiary BAUER Hong Kong Ltd. is involved in the construction of the world’s longest bridge over water, currently under construction in the Pearl Delta. The 50 kilometer link connecting Hong Kong, Macao and Zhuhai forms the southern ring closure of a gigantic infrastructure project.

The bridge consists of a multitude of individual structures, such as cable-stayed bridges and a 6.7 kilometer long tunnel, allowing uninterrupted passage of large vessels. Artificial islands form the end points and landing points. All structures are connected by a viaduct. 

The joint venture Dragages-China Harbour-VSL commissioned Bauer Hong Kong with the installation of offshore bored piles for the Hong Kong Link Road (HKLR) – a 10 kilometer long section from the border between China and Hong Kong to the Hong Kong international airport. Piles with 2,300 and 2,500 millimeters in diameter are up to 115 meters long and will be installed in rock at depth of 2 to 5 meters.

All the work on this 72 million Euro project to be undertaken by Bauer Hong Kong must be performed from the water – a serious challenge. Five BG 40 rotary drilling rigs will be used – four of them are custom-built, with longer masts and larger main winches. The rigs were transported by ships to the steel platforms, each accommodating only one machine. Further, there are pontoons for four bentonite plants and for 300-tons heavy cycle cranes and accessories. Over 100 drilling tools were assembled at the construction site. Actual construction work began in April 2013 and will go on until December 2014.
