The cost estimation of tunnel construction is subject to numerous uncertainties that can result in deviations between the predicted and real costs. There is no up-to-date model to estimate the costs of a tunnel structure. Within this Research Projekt methods for more precise cost estimate or cost calculation are developed on the basis of an analysis of the construction costs of recent road tunnel projects.

Development of an innovative separation method of used bentonite suspensions for economi-cally beneficial, resource-efficient and environmentally compatible disposal - Phase II
Aim of the research project is to improve or replace nowadays separation processes by adapting a new electrochemical separation process, the ‘electrocoagulation’, where no additional agents are necessary and incorporating it into a new developed processing system.
The findings of the Phase I are the start point for the development of an industrial prototype in Phase II.

In large cities and metropolitan areas, metro networks are of particular importance because they are unaffected by traffic congestion on the roads. This independence and the short journey times make the underground even more popular. In Berlin, for example, the number of passengers increased from 2008 to 2015 by almost 20 % to more than half a billion passengers per year.
However, diverse threats and incidents can lead to great impairments of the underground transport. A few possible scenarios are bomb threats, flooding, fires and gun rampages. For this reason it is necessary to further improve the resilience – resistance against damaging effects – of underground public transport systems.
In the U-THREAT project, concepts and technical solutions are being produced, firstly to run degraded mobility mode quickly after an incident, and then be able to return to normal operation. The basis is an evaluation scheme to determine the vulnerability of sections of a metro network and individual stations. Then measures will be prepared in order to improve the resilience of all the significant areas.
