DIGITAL CONSTRUCTION: BIM MODELS IN INVESTMENT MANAGEMENT DURING THE POST-WAR PERIOD

Post-war reconstruction of Ukraine necessitates the development and implementation of effective management decisions grounded in transparency, accountability, strategic foresight, and innovative approaches to the formation and utilization of financial resources. This issue becomes particularly relevant in the field of civil construction, where public expectations are exceptionally high and the scale of infrastructure losses demands systemic solutions and a comprehensive vision. The implementation of investment projects under resource constraints requires the integration of modern digital tools that enable continuous monitoring, evidence-based planning, accurate forecasting, and risk minimization. In this context, the application of Building Information Modeling (BIM) emerges as a next-generation tool capable of ensuring efficient management across all stages of investment project implementation. The purpose of this study is to conduct a comprehensive analysis of BIM’s potential to improve decision-making mechanisms, enhance resource control, increase financial transparency, and foster long-term trust among investors and stakeholders. The methodological framework includes systems analysis, structural-functional and institutional approaches, content analysis of regulatory documents, a review of international case studies, and testing of analytical models in the context of social infrastructure reconstruction projects. The findings indicate that the integration of BIM into investment project management reduces the risk of cost overruns, improves the quality of budget planning, eliminates duplication of functions, enhances the adaptability of management structures to uncertainty, and establishes a digital foundation for the sustainable development of the construction sector. The synthesis of theoretical principles and empirical evidence leads to the conclusion that BIM serves not only as a digital technology but also as a comprehensive management platform that increases the efficiency of national reconstruction policies in Ukraine. Moreover, BIM contributes to strengthening institutional capacity and supports the creation of transparent, accountable, and resilient investment ecosystems. Its wide-scale adoption could become a catalyst for accelerating reconstruction processes and improving the overall quality of governance in infrastructure development.
