Sažetak
Major contributions to the development of the observational design method in geotechnical engineering are reviewed. These contributions are discussed in regard of the duality of uncertainties related to knowledge based (epistemic) uncertainties and those related to the natural ground variability (aleatoric). Some common concerns related to the proper use of the observational method are discussed. It is shown that the use of the observational method is feasible only for cases where it can be anticipated that epistemic uncertainties might decrease as more observational data become available during construction. Among these, three cases of the possible development of the upper and lower bounds, and the most probable anticipated value of the ground parameter governing design, are illustrated and discussed. These cases made it possible to draw some conclusions on the suitability of the use of the observational design method regarding the serviceability and the ultimate (failure) limit states in view of ductile and brittle material behaviour.
