As a project passes through different phases, the level of development in a BIM model also increases to different levels namely LOD 100, 200, 300, and beyond.A BIM model can be utilized for pre-defined specific purposes, commonly known as use-cases. According to project stage requirements and project complexity, specific parameters are added to the existing information contained in BIM. These additions of pre-defined used cases can be described as BIM dimensions.These dimensions enhance the data associated with a model to share a greater level of understanding of a construction project.In the modern era, BIM technology has evolved from basic 3D & 4D dimensions to more sophisticated 5D, 6D & 7D dimensions that are poised to change the future of the AEC industry. BIM dimensions – 3D, 4D, 5D, 6D & 7D, each have its own purpose and are useful in finding out how much a project would cost, its timeline when it would be completed, and how sustainable it would be in the future.
