Abstract:Starting from the core concept of digital engineering management, the key technologies of digital engineering management are deeply explored. Firstly, it expounds the concept and significance of digital engineering management, emphasizing its remarkable effects in enhancing engineering efficiency, optimizing resource allocation, and other aspects. Then, it provides a detailed analysis of the application principles, characteristics, and advantages of several key technologies in engineering management, including Building Information Modeling (BIM) technology, Geographic Information System (GIS) technology, big data analysis technology, Internet of Things (IoT) technology, and artificial intelligence technology. Through the research on these key technologies, it offers a comprehensive technical analysis and practical guidance for the digital transformation in the field of engineering management, promotes the development of engineering management towards intelligence and high efficiency to meet the increasingly complex requirements of modern engineering construction, and improves the management level and comprehensive benefits throughout the entire life cycle of the project.
