The relevance of the topic of the article is due to the fact that currently there is no linking of the calendar plan to the schedule for the development of capital investments. The principle of constructing a schedule for the development of capital investments is proposed, which ensures the uniformity and proportionality of the use of financial resources. Schedules for the development of capital investments are constructed, each schedule for the development of capital investments corresponds to an image describing the change in the absolute value of the profitability of the investment and construction project. The use of a mathematical apparatus describing the movement of a material point can be used in the development of investment schedules and calendar plans for construction. The construction of construction schedules in the section of the construction organization project based on investment schedules will have a significant impact on the economic efficiency of investment projects.

The article discusses the peculiarity of determining the duration of laying concrete mix depending on the height of the installation horizon. As a result of the study, the design was justified, which was accepted as a representative object, a sample of standard values of machine time costs was performed depending on the height (number of floors) of the building, the dependence of the calculated value of machine time costs on the height of the floor (the horizon of the work) was obtained, the reliability of the calculated values was estimated.

Traditional methods of assessing the effectiveness of investment and construction projects do not take into account the possibility of changing the conditions of construction, the intensity of development of capital investments, depending on the prevailing conditions. This leads to the need to develop new methodological approaches to make rational decisions on the allocation of investments in the implementation of construction production. The article proposes to use the model of option pricing for a phased assessment of the effectiveness of the investment and construction project, depending on the changing factors of the internal and external environment.

The article presents the results of calculations and selection of a set of construction machines for the development of soil in the pit. In the course of the work, a comparative analysis and selection of the most cost-effective option was made. The results showed that the parameters of the selected technology may not coincide with the recommended.
