Thanks for doing this AMA! I used to work for some of the big underground contractors an engineer. I've helped bid jobs for TBM's but have never gotten to see one in action. What is the worst thing you've had happen on a job as a TBM operator?

Thank you for the response! Outside of injuries, what else has gone terribly wrong? Have you had extended downtime on the TBM due to a major issue? Have the wrong tunnel segments been put in place? Any experience with the tunnel flooding?

Do you have any preference between Herrenknecht or Robbins TBMs?
