A much shorter tunnel, but with two new underground train stations, is being built under Stockholm, Sweden.[1] It is about 1/6 of the Swiss budget (about $2 billion). It will be completed on budget and slightly ahead of time this year.[2] So it can be done.

But most often, even in Sweden, it is not. https://en.wikipedia.org/wiki/Hallands%C3%A5s_Tunnel https://en.wikipedia.org/wiki/Hallands%C3%A5s_Tunnel

  Indeed projects in Sweden run över budget too. I was saying "it can be done" not that it is always successful. Other recent successes: Norra länken 2.6 Bn SEK under budget (part of circle road around Stockholm). [1][2] Arlandabanan (train service to Stockholm AirPort), on time and on budget.

You can't compare those two projects.

  Clearly you can... Let's see: Underground?: Yes, Yes Budget: $2bn, $12bn (or whatever) On-time?: Yes, Yes Is a tunnel?: No, Yes ...

    You could apply this checklist to a sewage system also.

      Wouldn't you wany a sewage system to be on time?

    > Clearly you can... Let's see: One involves carving a 150km tunnel through a granite massif which is the Alps in a scale that never before was done in history of mankind, the other involves drilling a tunnel through alluvium and sedimentary deposits pretty much like any medium-scale tunneling work.
