Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Up to, but even on average, multiple meters certainly. You can actually check advance reports:

  • Project organisator AlpTransitGotthard has a monthly update. It isn't awfully detailed, though: no October data for one of the two pairs of still active attacks, the one from Sedrun to the South (they only report the passing of the originally planned meeting point of the final two tunneling attacks, which was moved South by 1.7 km); and daily averages of 12.4 resp. 14.8 m for the pair of attacks from Faido to the North.

  • For Sedrun, the contractor's progress report is not much help, either, but in the reports from 2007, you find earlier averages of 6-6.5 m for this (blast-excavated) pair of attacks, and data for the geologically most difficult section of the entire tunnel (a zone of fractured, expanding rock North of Sedrun): traversed at 1.4-1.5 m/day.

  • For the Faido tunnel boring machines, there is also the contractor's semi-regular weekly report (showing a progress of 110.9 resp. 73.5 m in the two tubes).
