A few quotes:
"More sand, less time."
"There is no such thing as good production, there is only better production."
which shows that this student got to the core of things.

The first part describes a trailerdredger from operational point of view, while the second part deals with the management part, with chapters as "Bunkercycle", "Borrow area management", "Data-analysis", "UKC-management", etc.....
