February Tunnel Progress

The T215 and T217 projects have successfully completed all tunnelling works this week with the docking of the 2 Herrenknecht Mixshield TBMs at Caldecott cripple siding tunnel and Napier stations respectively. 14 bored tunnel drives remain - bulk of which would only be completed in the second half of the year.

The next breakthrough will take place at Caldecott by TBM 3 under the T212 project around end Feb/early March. Its sister TBM 2 will subsequently arrive approximately 6 weeks later, concluding the tunnelling works for Stage 2 and TELC2 in April.

RC works for the station's internal structure continues, with excavation works starting at entrance A. Preparations for the reinstatement of Marina Gardens Drive over the completed subway are in progress with implementation scheduled next quarter.
