This paper explores the application of intelligent information systems (IIS) based on artificial intelligence in construction companies in the Balkans, aiming to reduce operating costs, increase competitiveness, and improve work efficiency. The paper proposes two key technologies: data warehouses and intelligent software agents, which enable real-time data collection and analysis, providing employees with the necessary information and knowledge for more efficient work and decision-making. Research conducted in 2023 in Balkan construction companies shows a low level of new technology adoption, with 92% of surveyed companies using information and communication technologies solely for basic business monitoring. The use of advanced technologies such as drones, IoT, and BIM remains limited, while a lack of management support further slows their adoption. It is concluded that construction companies in the Balkans lag global trends and that greater education, management support, and investments in digitalization are essential for making real-time IIS a sustainable solution for business optimization.
