![]() To comply with noise standards and ensure residents’ comfort, we installed noise- and dust-attenuation in these heavily urbanised zones. Accordingly, we built a ventilation building in the MCV shaft (40 m in diameter and 40 m deep), a TMB-launch shaft at Diamond Hill (40 m long and 32 m deep), a firefighting-access shaft connected to the 2 tunnels at Fung Tak (16 m in diameter and 32 m deep), and a cut-and-cover shaft 99 metres long at Hin Keng. The project also includes construction of 4 shafts. Our contracts include construction of a 2,475-metre using the blast method and a 1,400-metre twin-tube tunnel using a slurry TBM with an excavated diameter of 7.4 metres, and a 700-metre blast tunnel. The new SCL line in Hong Kong is divided into 15 main lots and calls for the construction of 18 kilometres of underground railway and 5 new stations and the development of 3 interconnecting stations.
