Building Information Modelling (BIM) has revolutionized the architecture, engineering, and construction (AEC) industry by enhancing the way buildings are designed, constructed, and managed. Initially, BIM was focused on 3D Modelling, enabling professionals to visualize structures in three dimensions, improving accuracy and communication. However, over time, BIM has evolved far beyond 3D. The addition of new dimensions, such as time (4D), cost (5D), and sustainability (6D), has transformed BIM into a powerful tool that addresses the entire lifecycle of a building, from design and construction to operations and maintenance.

BIM Evolution from 3D Design to 6D Lifecycle Management reflects the growing need for more intelligent and sustainable building practices. Each dimension of BIM brings new layers of information and functionality to the model. While 4D BIM integrates time and scheduling for better project management, 5D adds cost estimation, helping stakeholders manage budgets more effectively. The introduction of 6D BIM brings sustainability into the equation, allowing for energy analysis, efficient resource management, and long-term facility maintenance planning. As the industry continues to adopt and integrate these dimensions, BIM is paving the way for more innovative, efficient, and eco-friendly construction processes. In Building Information Modelling (BIM), the concepts of 3D, 4D, 5D, and 6D refer to different dimensions or aspects of a building project.
