Therefore an effective risk assessment and risk management is necessary to get additional information to determine indicators for critical situations. Several tailings observations showed an alteration in chemical and radiological parameters during rising saturation induced by climatic changes. These parameters are appropriate to stress indices. A systematically research on correlations between changes in stress indices and the phreatic surface is part of the research activities of the Bauhaus University in Weimar. The contribution presents the principle of this kind of monitoring, the soil mechanical background, details of the equipment and first results.

It addresses the problem of detailing in process simulation. The authors outline special boundary conditions for the simulation of cost-relevant resource processes on virtual construction sites. The approach considers different needs for detailing in process simulation during the planning and building phase. For simulation of process costs on a construction site (contractors view) the level of detail has to be set to high. A prototype for determination of process durations (and hereby process costs) developed at the Bauhaus University Weimar is presented as a result of ongoing researches on detailing in process simulation. It shows the method of process cost determination on a high level of detail (game between excavator and truck) through interaction with the virtual environment of the site.
