Three remarkable projects on retrofitting by base isolation are described in the paper. One of them is retrofitting of a 5-story stone apartment building. The operation was made without resettlement of the occupants. World practice provides no similar precedent in retrofitting of apartment buildings. The other project is retrofitting of the 60 years old non-engineered 3-story stone school building. This building has historical and architectural value. Unique operations which were carried out in order to install the isolation system within the basement of this building and to preserve its architectural appearance are described. Accumulated experience created a good basis for participation in the international competition announced by the Government of Romania for development of the design on retrofitting by base isolation of the 178 years old historical building of the Iasi City Hall. The structural concept, including the new approach on installation of seismic isolation rubber bearings in this building, is described and detailed results of the earthquake response analysis for two cases, i.e. when the building is base isolated and when it has a fixed base, are given. For all three buildings comparative analyses of innovative vs. conventional retrofitting are carried out. Different methods of conventional retrofitting are considered and their costs are compared with the cost of innovative retrofitting by base isolation.
