Prof. Ernst-Ulrich Hiersche, honorary member of STUVA, died in Karlsruhe aged 84 at the end of 2015. For all of twenty years, from 1977 to 1997, he more than pulled his weight alongside me as an extremely active member of the STUVA board. His creative spirit spurred on our joint endeavours and his omni-present humour also helped ease the occasional entanglements that life presents. We shall all miss him greatly.
On March 10, 2016, the Federal Highway Research Institute (BASt) in Germany held a workshop on “Increasing IT Safety for Traffic and Tunnel Control Centres” in Bergisch Gladbach within the framework of the Cyber-Safe research programme. 40 experts from traffic and tunnel monitoring attended this workshop. The participants involved were tunnel operators, tunnel managers, IT specialists and safety officers.
The opening of the Gotthard Base Tunnel on June 1, 2016 is an occasion for Siemag Tecberg to reflect on a project that involved unique challenges. The shaft hoisting system in the Sedrun part-section was built by Siemag Tecberg, who also operated the system during the construction phase. The hoisting plant was a critical logistical resource providing the means of access for construction supplies and of removal for the excavated material for the 8.5 km central section, which was driven by drill+blast.
The cooling for the underground worksite was provided by a further Siemag Tecberg technology, in the form of the “Pressure Exchange System” (P.E.S.). The P.E.S. has the function for efficiently supplying the underground cooling network with cold water from the surface.
