Balfour Beatty JV lands £249m Hong Kong tunnel contract

Balfour Beatty’s Far East joint venture Gammon Construction has won a HK$2.6bn (£249m) contract to install services and construct support buildings for a new road tunnel in Hong Kong.

Gammon will provide electrical and mechanical (E&M) facilitation for the new 5km tunnel from Tuen Mun to Boundary Crossing Facilities Island and will include the tunnel’s ventilation, road lighting, central monitoring and control systems.

The contract has been awarded by Hong Kong’s highways department with work already progressing and due to be completed in late 2020. Bosses say a workforce of 1,700 will be involved at construction peak. 

The contract also requires the provision of civil and building works for the construction of a number of tunnel buildings including the administration, toll control, maintenance depot and satellite control buildings, as well as the landscaping works on the landfall at either end of the tunnel.

Commenting on the award, Thomas Ho, chief executive of Gammon said: “Gammon is currently undertaking the design and build of the Southern Connection Viaduct Section of Tuen Mun-Chek Lap Kok Link project and we are delighted for another opportunity to play a key role in this important infrastructure project for Hong Kong.  Gammon is committed to working with its partners to ensure the delivery of the project to the highest quality, while maintaining excellent standards of safety."

To ensure the excellent standards of safety are preserved, Design for Manufacture and Assembly methods and an integrated digital project delivery approach will be adopted, according to Gammon.

Furthermore, at least 70% of the E&M works will be of modular construction and drone photogrammetry for 3D mapping and surveying will be used to assist in delivering the works to the highest standards of accuracy.  Other innovative solutions include a ‘flying factory’ (to facilitate off-site production), tailor-made cable laying trucks and off-site construction of the toll booths.
