Autodesk Navisworks has become one of the most essential tools in modern construction coordination. By using powerful Clash Detection workflows, project teams can identify design conflicts, reduce rework, and improve overall project delivery. This article highlights the best practices for clash detection in construction using Navisworks, including model preparation, clash rule setup, and coordination strategies.
1. Prepare Clean and Organized Models
To ensure accurate clash results, always start with clean and well-structured models. Remove unnecessary geometry, check naming conventions, and verify units. A consistent model structure allows Navisworks Clash Detection to produce more reliable results while improving performance during clash analysis.
2. Use Search Sets for Efficient Clash Testing
Search Sets are one of the most powerful features in Autodesk Navisworks. They make it easier to run repeatable clash tests, automate filtering, and maintain consistent coordination standards. Using Search Sets also supports long-term BIM workflows and aligns with construction coordination best practices.
3. Apply Rules to Reduce False Positives
Navisworks includes Clash Rules that help eliminate unnecessary clash notifications, such as overlapping insulation or intentional penetrations. Configure rules carefully to avoid false clashes, which can waste time and slow down coordination meetings. An optimized rule setup ensures the clash report focuses only on real, actionable issues.
4. Set Clear Clash Categories and Priorities
Organizing clashes into categories (e.g., Structural vs MEP, HVAC vs Electrical) helps teams focus on high-impact issues first. Using priority levels allows construction managers and BIM coordinators to quickly identify which clashes require immediate attention and which can wait for later coordination stages.
5. Use Viewpoints and Sections for Clear Communication
A clash is only useful when it can be clearly explained. Use Viewpoints, redlines, and section boxes to visually highlight the exact location of each issue. Clear communication helps reduce misunderstanding and speeds up the construction decision-making process.
6. Export Comprehensive Clash Reports
Navisworks Clash Reports allow teams to share findings with designers, contractors, and stakeholders. Final reports should include clash IDs, priority levels, screenshots, and notes on responsibility. A well-prepared report improves collaboration and ensures that clash resolutions are tracked accurately.
7. Maintain a Regular Clash Detection Schedule
Consistency is key. Running clash detection on a weekly or bi-weekly basis helps the team track progress and identify new conflicts early. Scheduling regular coordination sessions using Navisworks also strengthens communication across all construction disciplines.
Conclusion
Autodesk Navisworks remains an industry-leading tool for construction BIM coordination. By following these best practices for clash detection—clean models, rule management, Search Sets, clear communication, and structured reporting—project teams can improve efficiency and deliver higher-quality construction outcomes.
