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 soil reinforcement via the directed gaps arranged at the discharge cementogenesis solutions, widely used in construction on subsiding soils. During the development of the project strengthening of soil foundations, using the method of directional hydraulic fracturing can be applied in various constructive schemes of reinforcement of foundation depending on the foundation type, ground conditions and tasks. The article describes the method of quality control of cement soil and also shows its application in the production of works to consolidate the base of the building.
