**********************************************************
Hong Kong-Zhuhai-Macao Bridge Authority recently completed the tendering process of the design and built contract for the artificial islands and tunnel of the Hong Kong-Zhuhai-Macao Bridge (HZMB).
The main bridge of HZMB runs from the artificial island off Gongbei of Zhuhai and reaches Guangdong-Hong Kong boundary with a total length of 29.6 km adopting a bridge-cum-tunnel dual-3-lane arrangement. The contract mainly consists of the design and construction of an immersed tube tunnel of approximate 6.7km and two artificial islands. Having assessed, the joint venture led by China Communications Construction Co. has ranked as the first candidate in the tender assessment. The tender assessment result notice will be published tomorrow (November 18) in the Mainland China. The whole tendering process and its supervision were undertaken by the relevant authorities in the Mainland China.
The tunnel will become the longest immersed tube tunnel in the world on completion. Since the artificial islands and tunnel will be constructed in sea environment, it is anticipated that the technical difficulties and challenges will be of world-class level taken into account of the long distance ventilation and safety design, prefabrication and marine transportation of huge pipe segments, joining pipe segments under high water pressure as well as construction of the west and east artificial islands,etc.
The team members of the joint venture include AECOM Asia Company Ltd., Shanghai Urban Construction (Group) Co., China Highway Planning and Design Institute Inc., COWI A/S, Shanghai Tunnel Engineering & Rail Transit Design and Research Institute and CCCC Fourth Harbor Engineering Investigation and Design Institute.
The successful completion of this tendering process marks a new chapter of the project of HZMB. The contract will tentatively commence this year for completion by the end of 2016.
