If you’re basing your choice of machines solely on initial cost, and not taking into account the entire cost of operation and maintenance, you’re not seeing the whole picture. To calculate total cost of ownership, decision makers must consider:
What’s the manufacturer’s track record? Are they being honest about advance rates and
How much uptime will the machine and components have?
When difficult ground or fault zones are encountered, can the machine proceed through them?
Will the manufacturer help troubleshoot issues when they arise, or will you have to figure
it out alone?
“The age of the machine wasn’t a concern for us, it was a positive. We knew it could perform in harder, abrasive rock.”

What is the wear rate on cutters and other consumables that need to be maintained and replaced throughout the tunnel drive?
Is the machine built to last over multiple tunnel projects? Is the machine built with 10,000 hours of usable life?
In the business of tunneling, miscalculations are extremely costly. They mean missed project deadlines, costly repairs—and paying workers while your machine is being fixed. Having an expertly engineered machine and a strong tunneling partner means maximized uptime and your project being finished faster.
