The S10 expressway in the north of Upper Austria will become part of the trans-European transport network and provide better connection between the Freistadt area and the metropolitan area of Linz and the Czech Republic.

Since 2010 the 2.2 km long extension of Berlin's subway line U5 from Alexanderplatz to the Brandenburg Gate is being carried out by the municipal transport company Berliner Verkehrsbetriebe (BVG) and its subsidiary Projektrealisierungs GmbH U5 on behalf of the German Federal Government and the State of Berlin. Upon reaching its final position at the Brandenburg Gate on October 14, 2015 the Mixshield “Bärlinde” has successfully completed its tunnelling mission in Berlin. Behind the tunnel boring machine (TBM) are two 1620 m long parallel tubes, built through the historic center of the German capital. In the process a total of 1076 tubbing rings were installed.
In less than a year, the who is who from the international railway industry will meet again from September 20 to 23, 2016, at the InnoTrans in Berlin.

The construction industry accounts for roughly a third of the greenhouse effect, requires about 40 % of the global energy supply and produces a volume of waste exceeding 50 %. Ensuring that tunnel excavation material is utilized as completely as possible in this connection represents an important contribution to forming a future-oriented economic system by increasing efficiency and effectiveness.
