August 7th 2010 -
At the beginning of the dayshift, the TBM is at 7576.6 meters (24,857.6 feet) at a depth of 90 meters (295 feet). The TBM is averaging 19 meters daily. There is no overbreak. The TBM has begun a 1,000 meter long arching curve (south-east) since reaching the 7,393.9 meter mark. The tunnel is beginning to veer away from following the Stanley Avenue route.
They poured in the huge amount of money, and appear to have clear sailing. The shotcrete overbreak plastering appears to be completed. Since this is now very boring, no more reports from my end. We only have to wonder about rock squeeze, but this can't show up for 30 years. :)
