The paper presents the results of full-scale and numerical studies of channel deformation in the lower section of the KMK damless water intake. The article presents the main factors for the destruction of banks during floods and low water periods. As well as developed recommendations for protecting banks from erosion. As a result of studies of the process of intensive local reformations of an easily eroded channel in plan, hydraulic schemes for the occurrence of local bank erosion were developed both during steady and unsteady movement in an open flow

The development of the methodology for evaluating investment and construction activity systems determines that the most important requirement for management is perspective, which is inextricably linked to the predictive nature of the functioning of the management subsystem, which involves the use of a conceptual model. The main purpose of such a model is to ensure the effective operation of the management object, for this all the requirements and criteria for evaluating the management system are formulated from the standpoint of the effectiveness of construction production and its individual elements (stages, types of work, etc.).

The dynamic development of the construction industry in Russia is accompanied by an increase in the complexity of ongoing projects and, as a result, an increase in the flow of information processed. It is necessary to manage a large number of different in intensity, direction, volume, flow patterns of informational, material and technical flows, as well as the flow of regulatory influences. In this regard, it is advisable to use a multi-level approach in planning the implementation of investment and construction projects in order to increase the efficiency and intensify the construction industry. The article deals with the problem of regulation by economic methods of phenomena and processes occurring in the space of investment and construction activities, towards the realization of sustainable development goals. Options for the implementation of integrated control based on the investment program engineering control scheme are proposed, a flowchart of the algorithm for linking and implementing strategic controlling and operational management procedures within the framework of the integrated control of construction projects of technically complex and unique objects is formed

The need for modernization and technological development of the national economy of the country leads to the formation of regional cluster policy, which leads to the growth of the construction industry. The article reflects the principles of interaction of clusters with public-private partnerships, their assistance and assistance in the creation of successful production and infrastructure projects in the country

This article examines the concept of digital economy, problems and prospects of its development in the construction industry and development strategies

Assessment of investment value, making investment decisions, and successful implementation of investment and construction projects at all stages of the life cycle depend on a high-quality feasibility study of budget investments. The purpose of the work is to justify budget investments (calculation of the estimated (marginal) cost) by modeling and reducing the cost of the corresponding types of work of similar objects to the required capacity indicators or types of work specified in the design task or pre-project documentation.
The analysis of technical requirements and conditions affecting the formation of pre-project solutions (development), as a result, the possibility and feasibility of the proposed investment and construction project. Estimating the (marginal) cost of the construction performed in the framework of the development of documentation, justification of budget investments is carried out in accordance with the established administrative-territorial, organizational, technical and technological pre-design solutions and variational solutions, and implemented on the basis of the simulation values and types of work, object-analogue.
Justification of budget investments is provided by an example of calculating the estimated (marginal) cost, performed using indicators of the cost and types of work of an analog object and taking into account the features and requirements set by the design assignment and pre-project documentation.
The significance of the research consists in the practical application of the process of modeling the cost indicators of analogous objects in the formation of documentation on the justification of investments, assessment of investment value and making investment decisions.
