      Comment on "The first RECTANGULAR Tunnel Boring Machine (TBM)!"

      Although the area cut is rectangular, the cutting is still done circularly though. OK that is not surprising. But I don't get it. The small cutting heads do not cover the whole surface. Or is it me missing something?

        Absolutely right. TBM tunnelling is one of the techniques but it is not the only tunnelling technique. It is not one size fits all solution.

          Drill & Blast tunnelling is far more harmful to the workers' lungs compared to the TBM tunnelling.

            Sorry I replied at the wrong place. I repeat here: You are right. Cost is not the only reason why you may want to go for non-TBM tunnelling. As you have pointed out there are some other important considerations in favour of conventional tunnelling.
