Mechanized tunnelling is a highly technical construction process, which requires the establishment of precise objectives to consistently guarantee high quality and safety standards while still considering the aspects of time and cost reduction. In the tendering and construction phases, these objectives can be met by the application of a risk management strategy and the integration of quality assurance elements. The implementation of process controlling with the objectives optimization, error prevention and documentation provides a centralized monitoring element in the construction phase. External experts can monitor tunnelling activities in real time and submit recommendations in case of deviations. With downstream analyses, incidents can be evaluated and methodological errors identified.
