Clash Detection In BIM

BIM clash detection

Building Information Modelling (BIM) provides architects and engineers with everything they need for new constructions. BIM software allows you to render buildings in their entirety so that you can address structural problems, like clashes, immediately.

Clash detection in BIM is one of the most useful tools in good BIM software. It highlights inconsistencies between building models so architects and engineers know what changes to make.

However, there’s far more to clash detection. We don’t want to understate how vital this tool is in building design.


Why Use Clash Detection?

Clash detection in BIM is a boon to architects during the planning process. There are many reasons that, if you aren’t already using clash detection software, you should do so immediately.

Clash Detection Saves Money

Firstly, clash detection saves a ton of money. Being able to address conflicts between models allows you to make needed changes before you buy any materials. It’s far cheaper to fix clashes digitally, before construction, than to waste materials fixing the issue later.

Clash Detection Saves Time

Secondly, clash detection saves considerable time. When clashes are noticed during construction, the project comes to a halt. You may miss deadlines and disappoint clients as you scramble to fix the issue. With clash detection software, you’ll be able to prevent these issues. Consequently, you’ll hit the ground running come building time.


Clash Detection Leads to Accurate Estimates

Finally, you’ll get more accurate estimations with clash detection software. As a result, you won’t have as many accidents during the construction phase, and you won’t be oblivious to design issues. With fewer issues, you’re less likely to deviate from the initial estimation.

Types of Clash Detection in BIM

Bluntly stated, clash detection is any conflict within or between models. However, there are different types of clashes involving a diversity of potential issues. What are they?

  • Hard Clashes – The most straightforward type of clash. A hard clash occurs wherever two parts occupy the same space. This isn’t possible in the real world, which is why catching hard clashes is crucial.
  • Soft Clashes – Soft clashes refer to tolerance breaches. In other words, an object that enters the empty space another object needs to function properly is a soft clash. An example of a soft clash: a pipe blocking maintenance access to an elevator shaft.
  • Workflow (4D) Clashes – A workflow clash may be called a 4D clash because it involves conflicts that happen with time. These types of clashes usually pertain to scheduling and are thus the hardest to calculate.

Benefits of Using Revitzo for Clash Detection

There’s no getting around it: you need clash detection to stay up-to-date with modern construction. There are many BIM software options out there, though. Fortunately, it’s hard to go wrong with Revitso.


Revitso is highly sophisticated, pointing out even the most complex 4D clashes. Despite how advanced the algorithms are, Revitso is intuitive and easy to learn. It’s the perfect software for deploying to teams because it doesn’t take long to learn, meaning you’ll begin the architectural process much sooner.
