From May 30 to June 1, 2017, the Swiss Tunnelling Society (STS) is staging the 16th Swiss Tunnel Congress. As in previous years the first two days will take place in the Concert Hall at the Lucerne Culture and Convention Centre (KKL). The annual Tunnel Colloquium will be held there on Day 1. Day 2 is the main Congress-day which will be devoted to papers on national Swiss tunnelling and underground construction projects as well as international construction projects – many of which involve Swiss participation. The final day is reserved for an extensive excursion programme, which offers participants the choice of visiting no less than five different construction sites.
Swiss Railways (SBB) plan to provide a 4 m corridor along the entire Gotthard axis by 2020 in order to be able to transport semi-trailer (articulated) trucks with a height of 4 m by rail. The new building of the Bözberg Tunnel in the canton Aargau is the largest individual project with an investment sum of about 350 million Swiss francs. In addition to the existing two-track Bözberg Tunnel, a new two-track tunnel almost 2.7 km long is being built parallel to the existing tunnel. Drill and blast tunnelling started in autumn 2016. Working three shifts, a distance of 168 m has been conventionally excavated in soft ground. Drill and blast tunnelling started in autumn 2016.

Five bids were tendered.
The article in tunnel issue 3/2017 offers interesting insights into the tunnel structures in the Alb foreland (Albvorland Tunnel, Kleine Wendlinger Kurve, goods train link) and the fundamental application of BIM (Building Information Modeling) method for the implementation of the complex tunnel project.
