The article discusses the issues of organizational and technological approaches in the design of facilities to be reconstructed. During the operation of buildings, the reliability of their structures is subject to cyclical changes. The dynamics of loads, as well as damage resulting from operation, can have a significant impact on the strength and durability of construction facilities. The reasons for the technical inspection during reconstruction are analyzed. The diagnosis of structural failure is analyzed. In most cases, emergencies are the result of missed errors at the design stage of the project, construction of the construction site and its operation. To minimize such risks, additional measures are being implemented aimed at quality control at all stages - from design to commissioning. A number of conditions have been identified under which most defects in the design and operation of structures can be prevented even at the stage of development of the reconstruction project.

This article analyzes the organizational and technological solutions used in the investment and construction sector, aimed at significantly increasing the efficiency of construction production and optimizing labor productivity. The process of implementing investment and construction activities is a multifaceted set of strategic maneuvers aimed at attracting capital investments, improving organizational and technological management and successfully completing project initiatives. The integration of innovative approaches in resource management and labor organization processes serves as the basis for the formation of a sustainable competitive advantage and maximizing performance in the dynamically developing construction industry. Organizational and technological schemes for the implementation of investment and construction projects are considered. Attention is paid to the issue of complex turnkey contracts, which involve the preparation of preliminary contract documentation in two stages. The contractor studies the requirements put forward by the customer, after which he sends him his proposals, after approval and acceptance of which the risk of constructive and organizational and technological solutions is reduced.

The article is devoted to the issue of making organizational and technological decisions when the stock of information for alternatives to choosing the required tasks is either very small, or they are changing drastically. Since it is not easy to make an organizational and technological business decision due to the fact that it is not clear what the result will be, it is proposed to use game theory in conditions of uncertainty. What kind of decision will be made and which of the available strategies the designer will adopt depends on what economic effect will be obtained as a result of the implementation of the organizational and technological solution being developed. Game theory is a special class of mathematical models for decision-making under specific conditions. By choosing solutions in the wake of uncertainty, game theory formalizes possible knowledge about the course of action of the participants in the game in certain conflict situations and allows you to mathematically substantiate knowledge about a rational course of action in certain conditions. When constructing construction projects in environmentally unfavorable conditions, the risk matrix is compared and the best option for the development of a construction project is determined.
