The evaluation of the geotechnical safety of subsurface constructions such as caverns or mines as well as the prediction of underground movements on above-ground installations requires special work techniques and methods. Within its tasks in the field of the final disposal of radioactive wastes, the Federal Institute for Geosciences and Natural Resources has developed such methods and work techniques, for example, geological 3D construction.

For a comprehensive evaluation, it is often necessary, to apply various, partially overlapping, methods. The evaluation of the barrier integrity of an underground depot, for example, requires methods for the determination of the thermal, hydraulic and mechanical properties of the barrier rock in the laboratory and in situ; methods for the numerical simulation of the thermal, hydraulic and mechanical processes over very long periods, methods for the safety assessment and, last but not least, methods for quality assurance.
