BIM software is designed to support the application of Building Information Modeling (BIM) technology. But how should these software tools be classified, and what criteria are used for their classification?
The diagram above illustrates the application software framework of emerging BIM technology throughout different stages of the engineering project lifecycle. While some BIM application software—such as design and calculation software—share names with traditional software, they differ significantly in that they are all based on BIM technology applied within projects.
Professor Eastman and colleagues from Georgia Tech classify BIM application software into three categories based on their functions: BIM basic software, BIM tool software, and BIM platform software. Alternatively, BIM software can be broadly divided into two main groups: BIM model creation software and BIM tool software.
For example, 4D progress management software extends the 3D geometric model created by BIM modelers by adding time-related data, such as specific construction schedules for components like box girders, pile foundations, and bridge piers. This integration forms a 4D model, which supports construction progress management by allowing technicians to visualize changes in the project’s structure over time. By incorporating cost data—such as unit prices and total costs of materials like concrete and steel—into the 4D model, the software evolves into 5D construction schedule management tools. These 5D models enable project managers to oversee construction more comprehensively, ensuring smoother project execution.
In summary, this classification of BIM software and the criteria behind it aims to provide a clearer understanding and assist professionals in the field.
