Ove Arup & Partners Hong Kong and Aecom Asia are consultants for the scheme.
The reclamation work is for the Hong Kong boundary crossing facilities for the HZMB. The link will be almost 30km long, including almost 22.8km on bridges.
CHEC’s contract will start straightaway and is expected to complete in early 2016. The work involves reclamation of 150ha at the north east of the Hong Kong International Airport for the construction of artificial island. The project also includes construction of about 6,140m of seawall, which is mainly made up of 134 steel sheet pile cellular structure with diameters of 27m or 31m. More than 19 million cubic metres of backfilled materials will be used to support subsequent superstructure construction. The work will use ground treatment technology to achieve the strength within a short period.
Letting the contract had been delayed following a judicial review in relation to air quality issues in the environmental assessments and permits for this and another scheme. The review has now concluded, allowing work to resume. Bringing the schemes back on track is expected to cost at least an additional HK$6.5bn (£536m), which was approved this month. The additional costs include the use of faster construction methods to make up time.
