Тhe analysis of methods and means of evaluation of technical condition of building structures under construction. The developed algorithm of a complex estimation of state of reinforced concrete structures with expired period of preservation. The algorithm of complex diagnostics of a condition of constructions involving complementation of known techniques of estimation of parameters of safety of structures with joint processing of the results, is an effective tool for assessing the actual condition of structures and end-of-life.
