Renovation of the historic building after damage connected with foundations subsidence - case study

The paper delineates the study of a historic building renovation. It was built in 1900 and completed in 1939. Its both parts consist of different constructions. The old part was founded very deeply whereas the level of the younger part foundations was higher than the old one. After large floods, the walls started to crack, elements of the ceilings and roof under the extended part of the building slipped. It was expected that in the future a construction disaster would pose a serious probability of occurrence. In the study it was necessary to recognize the entire construction with a thorough investigation of the underground, old part of it and also the soil types density were examined. The main objective of the new research was to define the real reasons of the damage and to determine the possibility of repairing this building. The elaboration of the study results revealed a conception of supporting the walls of the building. The results indicated that the need to verify the reasons of the occurring damage in a complex and thorough way is tremendous, especially when a monument is concerned which was developed in stages in various historical periods
