Whether tunnels service rail networks or road vehicles, and whether they travel underground, under water or through mountains, instruments and solutions from Leica Geosystems provide accurate measurements and safe monitoring.

"Boston's massive 'BigDig' project has taken advantage of numerous technology innovations during its 15-year life. The latest technology success story is the project's use of Leica Geosystems' High-Definition Surveying (laser scanning) systems (Reporter 51, August 2004)." Leggi tutto

The Alp Transit Gotthard is an ambitious railway construction project, which will incorporate the world's longest railway tunnel of 57 km travelling through the Swiss Alps and under the St. Gotthard massif. Future passenger trains will journey at speeds of up to 250 km/h, adding further to the highly successful European high-speed network and bringing a huge reduction in travelling time. The combined surveying systems of
Leica Geosystems and Amberg Measuring Technique Ltd are greatly assisting the tunnel workers in their day-to-day work - not only reducing time needed to ensure that excavation is correctly undertaken, but also making
the whole construction process much more efficient and accurate. Leggi tutto

The project for the construction of tunnels as part of the new extension of Prague’s Underground was faced with certain space limitations due to the location of an existing station. In addition, the particularly rough terrain in the area had considerable influence on the position of the planned station. At the place of crossing, the line is located at a depth of only one metre under the riverbed of the Vlatava. This minimal depth of the overlaying formation prevents the use of the tunnelling method, and therefore there remains only one “classical“ method of construction – cofferdams. It was decided to use three cofferdams for the tunnel crossing situated in the Vlatava stream channel. Leggi tutto

In the lower Emmental, this 1.6 kilometre-long tunnel is being built below the River Emme. It is part of the Bahn2000 new construction section that will allow travel from Bern to Zurich. Using automated steering with a
3D-Machine Guidance System of Leica Geosystems, shoulders have now been laid in the biggest “Emmentaler Hole”. Leggi tutto

In the midst of harsh terrain, surveyors in astronaut-like garb stake out the route for a new gas pipeline. Determining their position
in real-time with the aid of satellites and the Leica MC1000 and SR 9500, they perform the groundwork for one of the largest-ever land based pipeline projects. Leggi tutto
