Process controlling for the hydroshield drives in the Lower Inn Valley (H3-4 and H8) / Prozesscontrolling bei den Hydroschildvortrieben im Unterinntal (H3-4 und H8)

The success factors cost, time, quality and safety can be considerably optimised on future tunnel projects through the analysis of the process data. A real-time data analysis system to monitor the mechanical tunnelling works was installed on contracts H3-4 and H8, part of the improvement of the Brenner rail corridor for the Brenner Eisenbahn GmbH (BEG). The intention was to exclude various technical, but also contractual interpretations from the client and the contractor, particularly regarding construction progress, which could have led to deadline and cost overruns, right from the start.
In order to clarify the sphere of risk during tunnelling work, BEG decided on the implementation of a process controlling system for the sections Münster-Wiesing (H3-4) and Jenbach (H8). The purpose is to promptly record the complex interactions between ground, structure and construction process, or ideally in real time. This should enable critical situations to be recognised early and the implementation of preventative measures in good time.
