Fort Canning update January

Contract 937 is for the construction of Fort Canning station along with two sets of main line tunnels - one towards Bencoolen station and another towards Chinatown station. The tunnels towards Chinatown station are being dug by a single TBM, known as TBM2, which will make two runs from the West Launch Shaft to the reception shaft at the end of Upper Cross Street, near the Chinatown station. Due to a tight fit amongst the tall buildings, the tunnels will have to stack one over the other in order to gain access to the reception shaft with the Bukit Panjang bound taking the lower level. An escape shaft will be built at Havelock Road to provide for emergency egress from both tunnels. 

Currently, TBM2 is undergoing a final cutterhead intervention where the blades at the front of the TBM are replaced and general servicing of the cutting equipment is performed. This is done under compressed air to stabilise the soil so that it does not collapse into the area where the workers are working from.

TBM2 has progressed towards the reception shaft and is expected to breakthrough at Upper Cross Street soon. It is currently in the vicinity of Havelock Road and checks have been performed on the CTE tunnel exits to ensure that there is no settlements or cracking of the roadway. All has been deemed safe thus far. TBM2 is expected to breakthrough in February. We assume that this would be accomplished in the first or second week of February and are awaiting the good news of another tunnel completed.

  1. hi. Do you have any photos taken at the bottom of the Queen St Shaft or the Upper Cross St one overlooking the operational DTL 1 overrun tracks?

    I would really like to see the seamless transition from the uncompleted section of DTL to the operational sectors. :) Do the DTL 1 tracks end just before the opening into daylight at the two shafts?

  2. May we have an update of the tunneling work along Upper Cross Street, please? There is a notice to inform members of public that the pedestrian bridge between Blk 51 Chin Swee Road and Central Square will be closed from 15 October 2014 to 25 Dec 2014. Grateful if we can have more information about the closure vis-à-vis the tunneling work. Thank you.

    1. Details of the tunnelling works are updated regularly on the sidebar. As of now the expo bound machine is currently being bored down Soloman Street and scheduled to dock at Upper Cross Street by December. The closure of the pedestrian bridge ties in with the duration in which the machine will pass under its foundation piles - possibly a precaution measure to ensure the safety of the general public. A PR contact should be printed on the notice; do contact them should you have further queries.

      Regards
