A fundamental issue in the development and engineering industries is the efficient management of complex structures during their entire lifecycles. Traditional fragmented techniques have been used, and this has led to instances of poor communication and subpar performance, particularly in the context of repair and restoration initiatives. Building information modeling (BIM) emerged as a ground-breaking strategy that offers a digital representation of a building's attributes and facilitates effective collaboration among several stakeholders. The current study examines how BIM impacts complex building management throughout the course of a structure's existence. It focuses on how BIM helps to advance maintenance procedures, environmental initiatives, and project effectiveness. Exploratory factor analysis (EFA), structural equation modeling (SEM), and literature research are the three phases of the study's methodology. A thorough investigation was carried out in Pakistan's Rawalpindi and Islamabad region utilizing a quantitative technique. The poll of 159 participants produced intriguing findings. The process of EFA serves to verify constructs and questions, ensuring their reliability and validity. On the other hand, SEM is used to assess the structural relationships between variables and their impact on BIM based lifecycle management. The findings suggest that the application of BIM is favorably influenced by each phase of a project, namely Design, Construction, Operation and Maintenance, Renovation and Retrofitting, and End-of-Life Decisions. This highlights the need to implement a complete BIM strategy across all stages of a project's lifespan, which may enhance facility management, decrease expenses, and promote sustainability. The results of this study have significant consequences for professionals and politicians, highlighting the crucial need to provide incentives and regulations to promote the use of BIM in building projects. © 2024
