The conceptual-theoretical basis of the research is outlined, in particular, the content of the economic-managerial interaction of construction enterprises-stakeholders in the context of modern development, the theory of "interested parties" and "management by deviations". It was determined that the successful interaction of the customer, the developer with the implementing enterprises and other stakeholders of development projects should be implemented in the format of temporary on-site structures for the administration of construction investment projects. Within such an organizational structure, successful coordination of actions between institutional participants and CDP executors, economic and functional controlling of the progress of project implementation and pre-determined state of achievement by executors of “strategic milestones” within the cycle, operational system and CDP cycle were realized. The components of scientific and applied support for the activity of stakeholder enterprises in the operating microenvironment of the construction development project (CDP) are substantiated. Analytical and applied support for the selection of BP strategies presented in this section provides a graph-analytical visualization of the vector of approximation of the stakeholder's trajectory from the coordinates of the current state to the state expected by the project development system. estimated duration of the cycle. The final components of the application support allow you to reproduce the influence of the course of the investment and construction cycle of the CDP on the leading indicators of the operational activity of each of the executing enterprises. The foundation was formed on the basis of interdisciplinary synthesis: it combines the modern principles of the theory of interested parties, economic reengineering and construction development – with methodical components of "management by deviations", adaptive management and synergy, digital technologies, management synergy in accordance with the consolidated resources of a multi-project environment on the basis of strategic compliance.
