摘要：The paper deals with the reasons for technical and moral deterioration of civil engineering structures, which constitute the enormous economic and political assets in every country. Extending their working life is an important social issue with always limited financial resources. In the next part, the following is presented: provisions of the building law, the procedure of the preliminary and detailed assessment with a structural analysis and proposals for possible interventions (e.g. rehabilitation, performance monitoring). The paper ends with a proposal of how to prepare the final report which should be issued upon the completion of the assessment, and the example of the structure after rehabilitation.
