I seriously doubt you can leverage economy of scale in something as labor intensive as building tunnels.

- jillesvangurp 2y agoWhy? They literally throw away machines that dig tunnels because they are built just for one tunnel. There's decades in between tunnels being dug for most big cities operating underground railways. A company that would be tunneling non stop could make a lot of improvements probably and get really good at it. There is no basis whatsoever that learning effects don't apply to the business of tunneling.
- manuelmoreale 2y agoMaking improvements != economy of scale. Digging 10 tunnels in parallel using 10 machines and 10x the people I bet won't save you much in the grand scheme of things. And the reason why they "throw away machines" is because most of the time those are custom built based on the project and the wear and tear is substantial.
