From 8 to 9 October, the 75th Geomechanics Colloquium of the Austrian Society for Geomechanics (ÖGG) will take place at the “Salzburg Congress” conference centre. This year’s colloquium is dedicated to Univ.-Prof. Dipl.-Ing. Dr. techn Gerhard Seeber (1925–2025), who has shaped generations of engineers in the field of power station construction. On Friday, 7 October, the 15th Austrian Tunnel Day will also be held at the Salzburg Congress Centre.

On 22 June 2026, the ElbX tunnel project commissioned by TenneT Germany celebrated the TBM-breakthrough. The tunnelling works, part of the large-scale SuedLink project, will connect Schleswig-Holstein and Lower Saxony over a distance of around 5.2 km. The Elbe crossing is one of the key sections of the power line, which will in future transport renewable energy from the north to the south of Germany.
National Grid, the transmission system operator in England and Wales, is expanding its high-voltage grid as part of The Great Grid Upgrade. A key project is a 2200 m long cable tunnel under the Thames from Gravesend to Tilbury.
The decarbonisation of major infrastructure projects is a key factor in achieving climate targets in the transport sector. Public clients can contribute to this by incorporating sustainability criteria into their tendering and award conditions. Such measures can create incentives to use lower-emission building materials and construction methods, whilst also improving transparency in supply chains. Using the example of Hamburg’s U5 subway line, this article shows how sustainability can be integrated into procurement processes step by step, in compliance with public procurement law. The focus is on criteria for reducing greenhouse gas emissions (GHG emissions) and for addressing environmental and social risks, particularly within steel and concrete supply chains.
The numerous projects involving alliance models in Austria provide valuable insights into partnership-based project delivery in German-speaking countries. Of the current total of 15 infrastructure...
The Wihalden Road Tunnel in the Swiss canton of St. Gallen is a key part of the regional transport infrastructure. In October 2025, the existing tunnel coating was completely renewed as part of a...
The Munich Tunnelling Symposium takes place every two years at the University of the Bundeswehr in Munich, Neubiberg. In 2024, the organisers were already delighted to welcome a remarkable 230 visitors. The ninth edition of this specialist event for tunnelling experts, held on 3 July 2026, broke the previous record by a considerable margin, attracting 280 participants.
Every year, millions of tonnes of excavated material are generated during tunnelling and underground construction projects. To date, most of this material has been disposed of in landfill sites without further use. The interdisciplinary research project Geo-BAB is investigating how such clay mineral-rich materials can be transformed into a low-CO 2 alternative to conventional cement through thermal treatment and chemical activation.
The European NIS2 Directive is intended to significantly strengthen cybersecurity in the EU – and in future it will affect far more organisations than before. IT security is therefore no longer an optional IT issue, but an integral part of responsible corporate governance.
