The article is a review of solutions, errors and mistakes in the project design and execution and their impact on reliability and durability of structures. Were used the results of inspections of 95 precast residential buildings situated in Warsaw, build in years 1961-1994. Inspections were made in years 2005-2006 and 2014. The summary of author researches [1,2,3,4] shows that the precast concrete prefabricated buildings can achieve real duration of use not less than 100 years. Taking into account quite good maintenance, intensive modernization and greater economic value of the housing stock in Warsaw can be assumed that their service lives may reach 120-150 years.

The prefabricated construction of housing estates in Poland was very common in times of centrally planned investments. It is estimated that 60% of housing developments created in Polish cities between 1966 and 95 are large-panel buildings. Currently, about 10 million Poles live in these types of blocks (over ¼ of the country's population). Hence, large-panel housing estates are an important part of Polish housing resources, and the problems associated with them affect the everyday life of a large part of society. The number of problems is significant and diverse, it's related to many areas - including urban planning, architecture, social and technical issues. This paper attempts to describe those multi-dimensional issues, indicate the directions of changes and evaluate the revitalization potential of prefabricated housing estates. The article concentrates on interdisciplinary and comprehensive nature of the revitalization that can improve the quality of the residents' life. Authors attempt to enter the issue of large-scale housing estates into the functioning and possibilities offered by the new revitalization act (2015). The article based on research and analyzes of over 18 housing estates. 110 buildings have been analyzed in terms of technical condition, construction, and internal installations. Inspections of buildings were carried out in 2005-06 and 2016-17 with employees of the cooperative, and residents (interviews). Documentation of buildings was found and analyzed.
