3D Coordination

For Current Information about BIM Project Execution Planning is currently at http://bim.psu.edu/Uses/default.aspx

Description:

A process in which Clash Detection software is utilized 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; less cost growth due to design coordination (i.e. change orders)
• Decrease construction time
• Increase productivity on site
• Prefabricate off-site leading to a safer and cleaner
• More accurate as built drawings
• Increase marketability

Resources Required:

• 3D Model manipulation
• Model Review application

Team Competencies Required:

• Ability to deal with people and project challenges
• Ability to manipulate, navigate, and review 3D
• Knowledge of BIM model applications for facility updates
• Knowledge of building systems.
