Acceleration of scientific and technological progress, increasing requirements for safety, comfort, and efficiency of capital construction projects, and the impact of the external economic environment, among other things, determine organizational transformations not only in investment and construction activities, but also in all periods and stages of the life cycle of buildings and structures. At the same time, increasing complexity of the organizational foundations of construction and housing and communal complexes, growing number and intensity of interactions between contractors lead to the emergence of disputes and conflicts between them and as a result, to the need to get out of such situations. A tool for fair conflict resolution can be a construction and technical expertise, which can be classified as judicial, pre-trial and corporate, depending on the institutional affiliation. This article discusses the distribution of tasks of construction and technical expertise on the time scale of the object's life cycle, as well as the theoretical basis for the manifestation of these phenomena.

Paper presents the software package that implements the ability to study hydroelectric power systems with complex hydraulic connections, planning long-term regime of hydro power plant with the requirements of water users on the example of the Votkinsk hydroelectric plants, and training for the calculation of the water-energy regime of hydroelectric power. The complex is developed in the high-level Python programming language based on the current requirements specified in the rules for the use of water resources of the Votkinsk reservoir. The calculation in the software package is performed by the direct method. Given that the software package is suitable for both research and training. To improve the quality of the calculation, we consider method of swarm optimization. The complex is planned to be used in the course of laboratory work on the planning of the HPP operation mode.
