Renewable energy is an inexhaustible source of energy by human standards. In the environment, they are represented by solar, wind, water, including tides, geothermal heat. At the moment, the main sources of energy are non-renewable, these are subsoil resources that will soon be exhausted at the current rate of use, these are oil, coal, nuclear fuel. Coal, gas, and nuclear power plants predominate in the energy system of the Russian Federation. Also, the main part of GDP is made up of hydrocarbon exports from Russia. The article defines the need for the country to transition from non-renewable energy sources to renewable ones, as the main ones, to maintain the same stability in the economy.

The construction of capital construction projects for objective reasons is constantly becoming more complicated, as a result of which the number of counterparties increases, and this in turn leads to an increase in the number of conflicts in interaction.

The resolution of conflict (disputable) situations a priori should occur on the basis of objectivity and fairness and can be carried out on the basis of an information model of a capital construction object.

This article discusses the organizational aspects of informatization of various types of construction and technical expertise (judicial, pre-trial and corporate).

For an objective and effective construction and technical expertise, the information model should contain not only normative and basic components, but also a component that describes the actual condition of the capital construction object, i.e. its real model. Thus, it is possible to reduce the cost and shorten the duration of construction and technical expertise. The best case of using such information models will be damping conflict situations in the interaction of construction participants or stopping development immediately after their detection.

Despite the attractiveness of using dry building mixes in the production of this type of work, products manufactured in factory conditions have a higher cost price than a building solution prepared manually directly on the construction site. This, naturally, increases the cost of construction. Manual use of dry building mixes, although it improves the quality of the work performed and labor productivity, still does not fully reveal the potential for the effectiveness of using this type of building materials. The use of mechanized methods in performing plastering work using dry building mixes not only improves the quality of the work performed, but also increases the efficiency of using dry mixes by reducing the volume of manual labor, reducing labor costs and reducing the overall cost of production. 

This article examines the movement of suspended and bottom sediments in the flow, which is considered as a complex problem in the process of water intake from rivers and canals for energy needs or national economy with dam-less water intakes. The article presents the results of the analysis of experimental and field studies conducted by the authors of the existing problems of assessing the intensity of channel processes in the territory of the dam-less water intake of the Amu Darya River. As well as the development of hydraulic regimes and flow regimes of sediment flow for the proposed structures based on experimental and in-kind studies for the proposed structures, which is the main goal of research work. During the experimental studies, measurements of depth, flow rate and, on this basis, changes in water flow rate were made, which were initially elements of flow rate in straight and curved channels.

A hydraulic structure is a civil or other structure installed on an artificial or natural water body, or in close proximity to it, or being an artificial water body itself. In the article, when making fundamental decisions on hydraulic structures, the following were taken into account:

design features of the floating nuclear power plant;

operational requirements for hydraulic structures;

extreme climatic, hydrological and seismic conditions of the construction site.

Among the design solutions characteristic of this facility, it is worth noting that reinforcement is provided to protect the slopes of the backfilled coastal site of the floating nuclear power plant from the effects of waves and ice. The construction of coastal protection and an approach dam is envisaged to be carried out using a flow method with the allocation of main sections and areas for work using coastal lifting equipment. 

The issues of development and improvement of the integrated system of construction pricing in the sphere of urban development relations are becoming increasingly relevant. The construction industry of the Russian Federation has received a full package of legislative, regulatory and methodological documents to address issues related to the assessment of the cost of construction products at all stages of the life cycle of capital construction projects. The authors assessed the built system of legislative and legal norms in terms of the principles of “block” and “seamlessness” in the application of the adopted and approved system of construction pricing by all participants in the investment process.
