The report contains brief historic and technical information about the Tsar-Bell as well as the structure of its pedestal and gives a detailed description of the instrumental inspection performed to assess structural state of the monument which included examination of the pedestal broad stone/brick masonry and metal fixing elements, check drilling and probing. The inspection results set up the basis for the restoration works. The authors describe basic technical solutions for strengthening of the pedestal foundation and underlying soil providing structural stability and protection. Some of the solutions were tried out before to strengthen foundations of old historic buildings and cultural heritage monuments. Restoration procedure of the pedestal superstructure is explained in detail including refurbishment of its metal elements, internal and external lining, special drainage systems installed under the pedestal. It must be noted that the main idea of this interesting project was to choose appropriate technical solutions and materials which allowed not only to restore the monument but also to preserve its historic appearance.
