These clashes affect project coordination heavily.
🔸 Time-Based Clashes.
Time-based clashes happen during project sequencing.
- Delayed construction activities.
- Incorrect installation sequences.
- Schedule overlap conflicts.
- Temporary structure interference.
- Resource allocation issues.
These clashes affect project timelines directly.
🔸 Why Clash Types Matter.
Different clashes require different solutions.
- Improves issue prioritization.
- Supports faster conflict resolution.
- Improves coordination workflows.
- Helps reduce construction risks.
