Real-Time 4D BIM & 5D Cost Simulation in Unreal Engine | Planned vs Actual Comparison
This video presents a real-time 4D BIM and 5D cost simulation developed entirely in Unreal Engine.
The system visualizes the comparison between planned and actual construction progress, integrating schedule and cost data into a single interactive environment.
Key features:
• 4D simulation based on construction timeline
• 5D cost analysis linked with progress
• Planned vs Actual comparison
• Real-time UI and data visualization
• Budget deviation tracking
In this scenario:
Planned progress represents the expected construction state at a specific date
Actual progress reflects on-site execution
Cost values are dynamically calculated based on progress
Deviations between plan and reality are clearly visualized
All systems, including logic, UI, and interactions, are developed using Unreal Engine Blueprints without external simulation tools.
This approach demonstrates how Unreal Engine can be used as a real-time construction analysis and decision support tool.
