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