Pile testing as a NDT-CE (non-destructive-testing in civil engineering) method provides information about the condition of foundations. It is also used as a tool for quality control. Real size test fields with sound piles, piles with flaws and piles connected with a foundation allow calibration of measurement devices and method comparison under "real" conditions. Such a site is planned on a BAM testing area south of Berlin. The joint use facilitates the establishment of the testing site as a national or European reference site.
Improperly built or managed tailing dams pose major risks to human lives and the environment. Research for risk reduction by new technologies including slurry handlings, stochastic modelling, development of a parameter framework as well as work on legislation and authorisation procedures will be done in the EC-funded project TAILSAFE. Focus of this paper is on geophysial techniques for structure investigation and monitoring.
