Abstract
This article examines the theoretical and practical foundations of assessing the economic efficiency of construction projects. Traditional indicators - net present value (NPV), internal rate of return (IRR), and life-cycle cost (LCC) analysis - are taken as the basis. The limitations of static methods in dynamic market conditions are analyzed, and modern mechanisms for improving efficiency are proposed: Building Information Modeling (BIM), digital twin technology, artificial intelligence, big data analytics, and blockchain. The integration of these digital tools enables real-time monitoring, risk reduction, resource optimization, and a significant increase in project profitability. The study emphasizes the transformative role of Industry 4.0 technologies, demonstrating the potential to reduce costs by 15–30 % and enhance the competitiveness of the construction sector in developing economies.
