Bedok Reservoir's Tierra

Contract 927 involves the construction of two mainline tunnels by TBM, a cripple siding tunnel by shotcrete lining and the Bedok Reservoir station. Italian contractor CMC di Ravenna is using two Robbins TBMs for this contract - TBM1 named Tierra and TBM2 named Kaida. This past week, Tierra broke through at the reception shaft of Bedok Reservoir station marking the end of its drive on the Expo-bound tunnel. Here are some photos of its assembly and subsequent break through.
