Appendix B-11: BIM Use: 3D Coordination
3D Coordination
Description:
A process in which Clash Detection software is used during the coordination process to determine field conflicts by comparing 3D models of building systems. The goal of clash detection is to eliminate the major system conflicts prior to installation.
Potential Value:
- Coordinate building project through a model
- Reduce and eliminate field conflicts; which reduces RFI’s significantly compared to other methods
- Visualize construction
- Increase productivity
- Reduced construction cost; potentially less cost growth (i.e., less change orders)
- Decrease construction time
- Increase productivity on site
- More accurate as-built drawings
Resources Required:
- Design Authoring Software
- Model Review application
Team Competencies Required:
- Ability to deal with people and project challenges
- Ability to manipulate, navigate, and review a 3D model
- Knowledge of BIM model applications for facility updates
- Knowledge of building systems
