Creating Incentive Mechanisms for Integrated Project Delivery

Due to their organisational structure and contracts, conventional project delivery models reach their limits in complex large-scale construction projects. In this context, Integrated Project Delivery (IPD) is an alternative regarding a joint project realisation...

Custom Timber Formwork for the Feuerbach Tunnel

The Tunnel Feuerbach project between Stuttgart‘s main railway station and the Feuerbach station, which was commissioned at a cost of around 187 million euros, has been completed. The breakthrough of the 3 km long tunnel in June 2020 was followed by the complex and innovatively designed extension of the tunnel inner shells and the widening structure near Feuerbach station...

Saving Energy and Resources and Reducing the Carbon Footprint by Innovations in Tunnel Construction

Climate protection and the geopolitical situation pose major challenges for our society. To protect the climate, we must reduce CO2 emissions and cut the consumption of fossil energies. The war in Ukraine makes us very aware of our economy‘s dependence on fossil energies and their availability and costs. This makes savings even more urgent than they already have been before. Likewise, the relevance of supply chains and availability of raw materials is becoming more and more obvious – also for the construction industry. An optimization of the design of conventional tunnels by owners and planners can lead to a significant reduction in CO2 emissions, energy and raw material requirements, and thus also in cost. In the article, potential optimizations are shown and explained with the help of examples.

Longitudinal Flow of Water Along Hose Assemblies Through Inner Tunnel Linings

For the construction of inner tunnel linings exposed to water pressure, both constructions made of waterimpermeable concrete and waterproofing with plastic sealing membranes are used. Both sealing options have in common that hose lines are led through the inner tunnel shell along a tunnel block. The article published in tunnel 3/22 examines the question of the extent to which water can flow along the longitudinal direction of the hose lines as a construction-related effect.
