In mechanised tunnelling, the sensor system on the tunnel boring machine (TBM) and its control system (navigation) as well as surveying and precast segment production all record a great amount of varied data. The analysis, visualisation and monitoring of this data represents an important instrument for efficient control of mechanised tunnelling.
The Gotthard axis is to be extended to become a 4 metre corridor. This will assist freight traffic crossing the Alps to be relocated from road to rail. The biggest part-project of this scheme is to replace the Bözberg Tunnel with a new 2.6 km long two track tunnel.
In its first phase the Lötschberg Base Tunnel was built in abbreviated form for financial political reasons and began operating in 2007. Of the 34.6 tunnel km, 21 km in the Frutigen-Ferden section are only single-track. The BLS AG invited tenders for planning the further development of the Lötschberg Base Tunnel on August 17, 2015. The planning work is due to start in 2016. It will embrace the double-track development from Ferden–Mitholz and the complete development of Ferden–Frutigen as an option.
Based on the state treaty between Austria and former Yugoslavia dating from 1977, the Austrian and Slovenian motorway operators, ASFINAG and DARS agreed in mid-April 2015 to jointly finance and execute the complete redevelopment of the almost 7.9 km long Karawanken Tunnel on the Karawanken Motorway (A11).
In September 2015 the ASFINAG embarked on the general redevelopment of the Oswaldiberg Tunnel on the A10 Tauern Motorway. In July the Austrian contractor STRABAG had been commissioned to tackle this...

The newly built operations control centre Betriebsleitzentrale (BLZ) in the Canton of Graubünden will operate 24 hours a day for the safety of all national and cantonal roads and will also support the control centre of the canton police and fire service operations in case of incidents; it has two workplaces provided with the most modern equipment
200 kilonewtons press down on a 20 cm wide, 30 cm high and 3.60 m long reinforced concrete beam. There is creaking and cracking, pieces splinter off, the first cracks can be observed. If there were...
An important phase has been completed in the construction of the approximately 2 km long, two-track Rosshäusern Tunnel on the line from Berne to Neuchâtel. After the decision to change the method of construction, the last blast took place in the upper half of the tunnel (top heading) 181 m west of the tunnel middle at the start of June 2015.
