How to Perform Collision Checking in Revit
When working with Revit for integrated project management, owners often need to present the model and ensure all visible collisions are resolved. Manually identifying every clash is impractical, so using the software’s collision checking feature is essential. This tool helps detect conflicts between mechanical, electrical, and structural components.
Follow these steps to run collision detection:
1. Open your model and link the civil engineering model (see Figure 1).
2. Navigate to the Collaborate tab, then select Collision Check and click Run Collision Check (refer to Figure 2).
3. Start by checking for clashes between mechanical and electrical systems. To optimize performance, you can exclude spray pipes and nozzles smaller than 50 mm before running the check. Make sure to select all options on the left and right panels, choose the current project in the upper tab, and click OK (see Figure 3).
4. Review the generated clash report. Select any issue and click Show to jump directly to the collision location in the model view. After resolving the conflict, click Refresh to update the report. Repeat this process until all issues are cleared (see Figure 4).
Once you’ve resolved clashes between mechanical and electrical systems, proceed to check for collisions between these systems and structural elements. Repeat the first two steps, but in step three, select the relevant structural categories—such as stairs, structural columns, and structural frames—and all mechanical and electrical models for collision checking (see Figure 5).
Benefits of Using This Approach:
This method saves significant time by automating collision detection while ensuring that every issue is addressed systematically. Even if the process is interrupted, you can easily resume without repeating previous work, maintaining a clear workflow.
