I looked into buying a used 24" TBM, turns out it's quite affordable to buy one, use it for a project, and sell it. It can be much cheaper than trenching.
Project didn't move forward. Pity.
- g8oz 12y agoHow much was it?
- RyJones 12y agoI don't remember the price of the TBM itself, but it was going to be about $300,000 to put in the tunnel. That includes purchase and resale of the TBM. Prices for used TBMs seem to be mostly measured in meters drilled, so if you're only putting a kilometer onto a drill with five, you're not going to hurt the value much.
- ChuckMcM 12y agoI didn't realize there was a market for small TBMs (or horizontal drills as they seem to be called) but the Robbins company [1] has some awesome data on that. You can get 250mm - 5000mm ones off Alibaba for $120,000 - $600,000. Amazing less than the price of a house :-).
