This case study is about the foundation and the site geotechnical potential evaluation for the rehabilitation of an emergency hospital building, placed in Bucharest. This building was strongly damaged by the main earthquakes that occurred in Romania, within the last 30 years (March 4th, 1977, August 30th, 1986 and May 30th, 1990). The building had, from the beginning, an unfavorable structural concept, in what concerns its shape in plane. The paper presents the methods used for the rehabilitation of the existing building foundation, together with the integration of a new foundation for a new building, that appeared necessary to be built, as a single solution for the strengthening of the old one. Important additional loads were considered for the proposed solution and thus an extensive study on the foundation and geotechnical aspects of the project were carried out, including a site geotechnical study, evaluation of bearing capacity and settlement, evaluation of safety factors on bearing capacity, before and after the strengthening. The paper also presents some considerations on the peculiarities of the seismic events that occur in Romania
