Recently the tunnel boring machine (TBM) for contract CR105 underwent its factory acceptance test (FAT). The FAT is where the client, in this case Taisei Corporation - China State Construction Engineering Corporation Joint Venture, goes to the manufacturing factory to see that the machine meets their expectations after production has completed. A series of tests are conducted to ensure that all is in order before the machine is disassembled for delivery to the client's project site.

The TBM for contract CR105 is a large diameter TBM measuring 12.66m across, equivalent to about 3 to 4 stories high. The single TBM will be used to bore a single tube through which two tracks of the Cross Island Line (CRL) will be laid. This is the first time a large diameter TBM is being used in Singapore to bore a single tube tunnel for 2 bounds. We look forward to the arrival of the TBM on our shores and the commencement of tunneling works.
