This document discusses Building Information Modeling (BIM). It defines BIM as an intelligent model-based process that provides insight to help plan, design, construct, and manage buildings and infrastructure. The document outlines the key aspects of BIM including 3D, 4D, 5D, 6D, and 7D modeling; software used; benefits; Industry Foundation Classes; BIM cloud; BIM maturity; and use of BIM in India and abroad. It also discusses some drawbacks of BIM such as complexity of software, cost, and lack of expertise in India.

7. What is 3D, 4D, 5D, 6D and 7D in BIM?

8. Problems faced when BIM is not used
• Flow of data
• Improper schedule of work
• Cost estimate is tedious and not accurate
• Digitalization of data is less
• Clash detection becomes very difficult to notice
• Reinforcement details in junctions
• Energy analysis

25. Drawbacks of BIM
• Complexity of software used for BIM
• Cost of software
• Lack of BIM knowledge in India
• BIM course is only available abroad
• The computer system running these software needs high end specifications

26. Conclusion
• BIM is promising and more advantageous compared to the traditional
process, but still it has several setbacks as the technology is still in
primitive stage.
• A significant amount of development is to be done in information flow and
interoperability of the software.
• Additional training material is to be provided with software to learn the
complicated features.
• In India, universities should start teaching BIM as an academic course to
make the people perfect in this field.
