Completely agree that the 17m per day seems very conservative and hence my assumption that the geology of North Yorkshire was the likely issue. Can't really see it being an ideal tunnelling geology if Strabag have been allowed to incentivise themselves so nicely - throw out a highly cautious estimate then claim bonuses (assumed) for improving massively on that figure? Doesn't give me any confidence in the baseline geotechnical report and its parameters.
