This research takes the construction companies and supervision units of megaprojects as the research objects and studies safety issues in construction decision-making for megaprojects. Using evolutionary game theory, we construct an evolutionary game model of safety decision-making behavior for construction companies and supervision units based on the bounded rationality assumption. The interaction and dynamic patterns of safety behaviors between the two construction entities are analyzed. Additionally, system dynamics Vensim PLE 10.2.1 software is employed to simulate and analyze the behavior of single entities as well as the impact of exogenous variables on the safety decision-making choices of both units. The research results indicate that positive choices in safety behavior decision-making contribute to enhancing the stability of megaproject construction. Exogenous variables significantly influence the safety behavior decisions of both the construction companies and the supervision units in megaprojects. An increase in cooperation benefits between the two parties fosters their active collaboration in completing mega engineering projects. This research promotes cooperation between construction companies and supervision units during a construction process and provides a reference for the safe and orderly implementation and development of megaprojects.

Operational inefficiencies in healthcare buildings and sustainability issues have become increasingly prominent. The root cause of this phenomenon is the irregular and incomplete structured data related to hospital user activities and spaces that are difficult to resolve using traditional manual methods. In order to solve this problem, an automated mapping approach is presented for hospital user activity and space. Using the Revit API technology and the C# language on the Visual Studio platform, a program for automated mapping is developed. It achieves the automatic mapping of hospital user activities and spaces, along with automatic calculation of utilization rates. An illustrative case study is conducted, focusing on the activity data and building space utilization of healthcare users at Shanghai Renji Hospital. The results indicate that (1) This method can realize the automatic combination of hospital user activities and hospital spaces, and hospital administrators can optimize the utilization rate of hospital spaces quickly and accurately. (2) This approach is highly adaptable, especially to changes in hospital user activities and hospital spatial data. (3) This method promotes the sustainable development of healthcare buildings and has great practical application value.

Based on grounded theory, this study examines how Building Information Modeling (BIM) technology supports practice-oriented teaching reform in engineering management. Primary data were collected through in-depth interviews with engineering management educators, industry experts, and students, and an interview-based theoretical framework was developed by using qualitative research methods. The findings indicate that BIM technology significantly improves practical teaching in engineering management by improving management capabilities, such as teamwork, collaboration, and communication and coordination, as well as technical and modeling capabilities. A comprehensive evaluation based on the entropy method and the extensible cloud model further indicates that the application of BIM technology effectively promotes innovation in engineering management education. The study provides a theory-driven reference for cultivating engineering management professionals with digital and international competencies.
