FCC to build two new sections of the Singapore Metro worth 334 million euro

  • FCC already had a contract for two sections of the Metro, one of which was completed in May and the other is ongoing
  • The company's contracts with the Singapore Metro amount to 600 million euro

 

Today Singapore's Land Transport Authority (LTA) awarded FCC's Austrian subsidiary, ALPINE, a contract to build two new sections of the Metro totalling 4,000 metres; the contract is worth 334 million euro.

In May, ALPINE completed the construction of a previously-awarded section, worth 74.3 million euro, and last week achieved breakthrough in tunnelling work on another section, worth 190.6 million euro.

The contracts awarded today are for sections C-917 (1,800 m) and C-918 (2,200 m) of Line 2. Both sections will be built almost entirely as twin tubes with an external diameter of 6.6 m and will be lined with prefabricated concrete segments. Construction should be completed in 46 months.

  • Section C-917 will include the Blackmore and Sixth Avenue stations, each of which will measure approximately 183 m.

The tunnel's twin tubes will be created using two tunnel boring machines (TBM) and will be lined with prefabricated concrete segments.

  • The second section, C-918, will consist of a 920-m twin-tube tunnel; Duchess station, which will measure 234 m; a 445-m section of cut-and-cover tunnel; and 560 m of twin tube with an external diameter of 6.6 m.

Two slurry-type TBMs will be used to build the two 920-m tubes, while one Earth Pressure Balance TBM will be used for the 560-m section; again, these sections will be lined with prefabricated concrete segments.
