This article is dedicated generalization of the approach to the formation of the integral potential of organizational and technological solutions. The scheme of decomposition of the main elements of a construction project is presented. Considered and described in detail the research algorithm and the formation of the integral potential of organizational and technological solutions and components as single integral potentials. It is proposed to divide the studies into following phases: selection of the unit capacity to be considered through the construction project decomposition into elementary components; carrying out expert studies to identify key parameters that influence the performance of a single building; development of a mathematical model based on regression dependence; the use of mathematical models to improve the performance of the integrated construction project potential. Components of the “elements - construction project” system are in line with the basic provisions of systems engineering, which are its subsystem. It was selected groups of professional experts with experience and knowledge in their respective fields. As a rule, they are managers and chief engineers of construction companies participating in the polls as experts. The formation of a mathematical model of a single integrated potential is based on the assumption that the probabilistic nature of addiction, but a tool for its construction will be a multifactor regression built on the basis of probabilistic and statistical methods. The examples of the practical use of the new tools such as an integrated potential of organizational and technological solutions are considered. Having numerical characteristics of individual integrated potentials, one can create indexes and algorithms to form the integrated potential of organizational and technological solutions of the construction project.

This paper considers and asserts the need to obtain the results of inspection of a building at the stage of its commissioning in order to apply comprehensive methodology for assessing its residual life. The author proposes to build regression relationship by correlating the levels of the time series dynamics of stress at certain points of the object calculation scheme considering the results of subsequent surveys. It allows estimating the wear rate of structural elements. The assessment of the reliability and durability of the building frame in a deterministic form is based on the limit states method. The application of this method allows taking into account the random nature of not only the combination of existing loads, but also the strength properties of construction materials by creating a system of safety factors.
