scope:

This Standard applies to performance monitoring of the ground, structures interacting with the ground and geotechnical works. Specifically, this Standard is applicable to field instrumentation and measurements carried out in connection with site investigations of soils and rocks in accordance with EN 1997-2; in connection with the Observational Design procedure in accordance with EN 1997-1; for ground behaviour evaluation, e.g. unstable slopes, consolidation etc or the proof or follow-up of a new equilibrium within the ground, after disturbance of its natural state by construction measures (e.g. foundation loads, excavation of soil, tunnelling); for the proof or follow-up of the stability, serviceability and safety of structures which may be influenced by geotechnical construction; for perpetuation of evidence; for the evaluation and control of geotechnical work.
