that control TBM performance are:
Rate (meters/machine hour)
Utilization (machine hours/shift hours)
Wear (tool changes per
order to improve Tunnel Boring Machine (TBM) excavation performance it will be necessary to increase
the Tunnel Boring Machine (TBM) penetration rate and the Tunnel Boring
Machine (TBM) utilization while decreasing Tunnel Boring Machine (TBM) downtime
and tool wear.
daily labor rate on a major city tunnel project, can be $100,000/day or
more. If the excavation duration is overrun by 10 working days, the
cost will increase by $1,000,000, not to mention

Machine (TBM) excavation
productivity over the last 40 years.
daily labor rates may not be as high as in a major city, however, if you wish to improve
your Tunnel Boring Machine (TBM) productivity, we may be contacted as follows:
