Abstract
The article analyzes the application of BIM (Building Information Modeling) systems in intelligent design, focusing on process and cost optimization in construction. The authors discuss the benefits of implementing BIM throughout the entire life cycle of a building, from the pre-design phase to operation. BIM enables rapid concept analysis, supports interdisciplinary collaboration, streamlines cost estimation, and improves construction management. During the operational phase, BIM supports efficient facility management through real-time data collection and updates. The authors emphasize that the future of construction lies in integrating BIM with technologies such as IoT, artificial intelligence, and augmented reality. Despite the low level of BIM adoption in Polish companies, the trend of digitalization in construction is inevitable, and firms effectively implementing these technologies will gain a competitive advantage.
