I don't know anyone who will ever see, much less operate one of these machines, but that doesn't mean it's not fun to watch.
If you're technically oriented you'll want to watch the entire thing. For those of you who are in a hurry, I recommend watching the part about drilling (:20 to 3:10) and then the part about installing the concrete lining (5:25 to 7:25).
I can't take credit for finding this video. Ted Cushman linked to it from the Coastal Connection newsletter. Ted is one of the best construction writers around – you can find some of his stories on the Coastal Contractor website (the newsletter sign-up is part way down the page).
