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.
