The cost of inaccuracy adds up fast. Here’s how to stay on track.

In conventional tunnelling, even a few centimetres of overbreak can mean thousands in extra material costs – not to mention delays, increased labour, and additional support measures. When excavation drifts off course, budgets follow.

In our numerous international projects, we’ve seen first-hand how even minor deviations can lead to significant financial impact. That’s why automated navigation isn’t just about precision—it’s a cost-saving necessity. With TUnIS Navigation Roadheader, roadheaders maintain precise alignment with the tunnel profile, helping to:

  • Minimise overbreak: Reducing unnecessary material use.
  • Avoid costly rework: Staying within design tolerances.
  • Increase efficiency: Cutting down on survey time and manual adjustments.
  • Improve project timelines: Keeping excavation on schedule.

With real-time data from total stations, inclinometers, and laser-based sensors, the system continuously monitors and corrects deviations. So you don’t have to pay for them later.
