This paper examines the problems and obstacles that arise during the implementation of investment projects in the field of capital construction, between the customer and the general contractor (a subsidiary of the customer). To solve the problems, it is proposed to develop specific measures to modernize the investment and construction activities of the customer company, in accordance with the economic development strategy adopted in Russia, based on digitalization. Information systems and technologies offer great opportunities for the development of various aspects of economic activity. One of them is information systems for managing investment projects. As a result of the work, the authors formulated the main directions of development and proposed solutions for modernizing the investment and construction activities of the customer company.

The technologies for producing ultrafine copper powders are examined. The influence of various parameters on the processes of electrocrystallization of particles is studied. Various mechanisms for producing particles in the presence of water-soluble polymers are presented. The ultrafine copper powders obtained using different electrolysis modes. A review of advanced electrochemical methods for producing ultrafine copper powders with the addition of various stabilizers particle growth, further ways of developing the technology of these technologies are highlighted.
