It would not be appropriate for me to provide information on the expenditure incurred on a daily basis by any of Crossrail's Tier 1 Contractors, as this is commercially sensitive information.

I would note however that complex tunnelling projects are managed and costed using long-run average production rates. These production rates take account of maintenance activities and transits through subterranean structures, like the new Crossrail Canary Wharf station. These stoppages should not be viewed as additional costs but as a normal part of a complex tunnelling project.
