A joint venture between Dragages et Travaux Publics, part of France's Bouygues construction group, and local firm Zen Pacific Civil Contractors has started work on the 1.78km Tsing Tsuen tunnel in Hong Kong. The scheme is part of the consortium's £150M design and build contract for the Kowloon-Canton Railway Corporation on the Kwai Tsing tunnels, part of the £4bn, 30.5km West Rail project. The twin Tsing Tsuen tunnels will be built using the first mixed face earth pressure balance tunnel boring machine to work in Hong Kong. The first 8.44m diameter tunnel will take about six and a half months to bore. The TBM was built by NFM Technologies of France and assembled by Shanghai Heavy Machinery Plant in China.
Atkins China is the design engineer and Ove Arup is the independent checking engineer.
