Gammon Construction, a 50:50 Far East joint venture of British infrastructure group Balfour Beatty and Asian conglomerate Jardine Matheson, has won the £249m ‘Tuen Mun-Chek Lap Kok Link – Northern Connection Tunnel Buildings, Electrical and Mechanical Works’ contract from the Hong Kong Highways Department.
The works involve electrical and mechanical (E&M) facilitation for the newly constructed 5km tunnel from Tuen Mun to Boundary Crossing Facilities Island and include the tunnel’s ventilation, road lighting, central monitoring and control systems.
Under the terms of the contract, the company will also be required to provide civil and building works for the construction of a several tunnel buildings, including the Administration, Toll Control, Maintenance Depot and Satellite Control buildings, and landscaping works on the landfall at either end of the tunnel.
The company will adopt Design for Manufacture and Assembly methods and an Integrated Digital Project Delivery approach to ensure the safe and efficient execution of the contract.
Nearly 70% of the E&M works will be of modular construction and drone photogrammetry will be used for 3D mapping and surveying 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.
Gammon Construction CEO Thomas Ho 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.”
Works have already begun and are expected to be completed in 2020. Nearly 1,700 people will be employed during the peak of construction.
Balfour Beatty finances, develops, builds and maintains complex infrastructure such as transportation, power and utility systems, social and commercial buildings. Gammon Construction is primarily involved in the Hong Kong and Singapore roads sector.
