BIM Model


Building Information Modeling (BIM) is a management information system for the construction industry. Based on the process of intelligent three-dimensional models, it enables engineering construction professionals to obtain relevant insights, analysis and tools, so as to plan, design, construct and manage buildings and infrastructure more efficiently .

The application of BIM technology is used to design and document building and infrastructure design. The BIM model covers every detail of the building. This model can be used for analysis to explore design options, and visualizations can be created to help stakeholders understand the appearance of the building before construction. This model can also be used to generate design documents for construction.
