Summary:

The article presents a methodology of technical condition assessment of masonry and timber structures of historical buildings, demonstrated on the example of palace complex at Gorzanów. Based on a comprehensive diagnostic study prepared by the authors, both on location and in the laboratory, a flowchart was developed to illustrate technical condition assessment procedures for historical buildings as well as for determining existing damage. The flowchart presented here may be found helpful by those providing expert opinions while designing their research and determining damage causes and investors who undertake such a difficult task as an adaptation of historical buildings to modern functional requirements.
