The £150million Glendoe scheme ground to a halt just two months after it opened following rock falls within its massive water tunnel.
Thanks to Hypocentre who pointed this out to me. We've already had our rockfall in the Niagara Tunnel, even before it's built! I wonder if it was the same contractor? Can't be too many of those around the world....
Oh, pooey, it's some other Austrian-sounding company - Hochtief. It was 20,000 tons of rock, and they used an unlined TBM tunnel.
Maybe they're Austrian cousins?
Investigations of the exact quality and condition of the rock at the location of the rock failure and the exact causes of this embarrassing, costly and serious situation for a brand new hydroelectric power station project continue.
