Throughout the construction phase of the Ceneri Base Tunnel, DMT's surveyors performed regular control measurements to ensure that the tunnel follows the route it should.
The instrument of choice was our surveying gyroscope GYROMAT 5000 - the most accurate precision-surveying gyroscope in the World. DMT was also responsible for the control measurements of the Swiss Gotthard Tunnel, particle accelerators and large scale underground sewer systems around the world.
