摘要：Technological and constructive decisions of modernization and reconstruction of large-panel buildings of the first mass buildings are considered in the article. The technology of the reinforced concrete diaphragms of the building hardness brings the seismic stability of the building to the normative level. The technologies of erecting a building with bay windows, as well as the construction of attic floors by the method of mounting bulk units enlarged onto the span have been developed. The folding volumetric blocks and the technology of their installation are proposed. The analysis of reconstructive works in two variants showed their rationality and financial attractiveness in comparison with the dismantling of buildings.
