Abstract
Construction records from six projects which employed full-face TBMs to drive 18 km of tunnel in sedimentary rock have been analyzed. More than twenty individual causes of delay could be identified. Delay causes are characterized on the basis of frequency and duration of incidents. Average utilization and downtime distributions are presented for each project, and frequency distributions of downtime per shift are discussed.
