![]() The ground-freezing method was used in this area because of the high permeability of the soil increased the risk of water seepage. ![]() Ice walls were used for the first time in our construction to stabilise the earth before tunnelling works were started for the TEL’s Marina Bay station. These ‘non-invasive’ methods include using ground vibrations or electric currents to determine the resistance of the soil, which is useful in built-up areas where digging is not feasible. Special methods to assess soil conditions were used in place of traditional borehole methods in some areas. To ensure this could be done safely, improvement works were carried out to stabilise the ground and facilitate the micro-tunnelling and mining.Ģ4-7 monitoring for settlement and movement with real-time monitoring instruments kept disruption minimal to Orchard MRT Station, one of the busiest in Singapore. ![]() This elevated depot will be the first of its kind, built to support the immense weight of hundreds of trains.įor the first time, a retractable micro-tunnel boring machine was used to install internally interlocking pipes to connect the underpass across Orchard Boulevard to the TEL and North-South Line’s station platforms. This translates to a land savings of over 60 football fields (44ha). Creative design with circles and marketing icons.

The TEL will have the world’s first four-in-one train and bus depot, with three train depots and one bus depot having the capacity to house 220 trains and 760 buses in multi-storey complexes.
