When it comes to Building Information Modeling (BIM), most people are familiar with the basics—3D modeling, enhanced collaboration, and improved efficiencies in construction projects. However, there are several aspects of BIM that are less commonly discussed but offer significant benefits and challenges. Here are 10 things nobody told you about BIM.

1. BIM is Not Just Software; It’s a Process

Many people equate BIM with software solutions like AutoCAD, Revit, or Tekla. While these tools are a critical part of BIM, it is more importantly a process—a way of managing information across a construction project's lifecycle, from design through to operation.

2. It's Older Than You Think

The concept of BIM dates back to as early as the 1970s, although it didn't gain mainstream acceptance until the late 2000s. This long history has allowed BIM to evolve into the robust and sophisticated methodology we know today.

3. BIM Levels Exist

From Level 0 to Level 3, BIM maturity levels indicate the depth of technology integration and collaboration in a project. Each level has specific criteria and deliverables, and not every project requires the highest level of BIM maturity.

4. Data is King

One of the greatest benefits of BIM is its data-centric nature. The model can store an immense amount of data, from the material properties of a brick to the scheduled maintenance of an HVAC system. This data can be invaluable for facility management long after construction is complete.

5. Legal Issues Can Get Complicated

BIM fosters collaboration but also opens up questions about data ownership and liability. It’s crucial for all stakeholders to have clear contractual agreements that outline these and other legal matters.

6. Facilitates Sustainable Building

Through energy analysis tools, BIM can help predict the future energy consumption of a building, thus informing sustainable design decisions from a project’s outset.

7. You Can Conduct “Clash Detections”

BIM software can automatically detect when different elements of a model (like electrical and plumbing systems) conflict or "clash," thus saving time and money by addressing these issues before construction begins.

8. Remote Access and Collaboration

Cloud-based BIM platforms enable teams to collaborate in real-time from anywhere in the world, making it easier to manage projects that have globally dispersed teams.

9. BIM is for More Than Just Buildings

Though it’s most commonly associated with buildings, BIM is also used in infrastructure projects like roads, bridges, and utilities. Its principles are broadly applicable across various forms of engineering.

10. It’s a Continuous Learning Curve

BIM technology is continually evolving, with new features and capabilities being added regularly. Staying current requires ongoing training and adaptation, making it a never-ending learning process.

In Conclusion

BIM is a multi-faceted tool that goes far beyond its most talked-about benefits. Understanding these lesser-known aspects can provide you with a more comprehensive view of what BIM can do for you. So, the next time you're considering a construction or infrastructure project, remember these ten points to make the most out of BIM.
