I don't read German so maybe this is covered in your article but what does strict planning have to do with getting a TBM unstuck or fraudulent materials? Wouldn't these issues point towards a lack of planning/quality control?

If your car engine breaks down you did a bad route planning?

There are things that can't be planned for.

One of the major problems detected was the fact that they had to drill through dolostone, which is a huge technological challenge. When mixed with water it results in a soupy mixture, which is almost impossible to work with in drilling a tunnel.

The did exploration drillings in 1993, but engineers where still pretty worried.

It was only in 2008 that the engineers lost the last of their concerns.

Such a huge project comes with technical uncertainties. What do you want to do about it?

Well if they caught it then there was quality control after all, wasn't there?

As I note, I can't read German so I don't know what or when the fraudulent materials were caught. If they weren't caught until they were installed then no, there wasn't proper quality control.

My more important question is how does catching fraudulent materials have anything to do with strict planning?

Controls are built into the process from the onset.
