Appendix B-13: Model Use: Coordinate Design Model(s)

Coordinate Design Model(s)

Description:
Using 3D coordination software to compile a federated model of design models for performing automated 3D collision detection to identify potential coordination issues along with performing a visual analysis to identify potential spatial design issues.  The federated model may include permanent design elements, temporary construction elements, and potential operational elements including clearances or other furnishings.

Potential Value:

• Reduces or eliminates field conflicts
  • Reduces project cost
  • Reduces project schedule
  • Increases project quality
  • Increases workforce productivity
  • Reduces construction waste
  • Reduces field generated requests for information
• Increases spatial reliability
  • Enables  increased levels of prefabrication and modularization
  • Enables installation of hangers for MEP or structural elements prior to concrete placement
• Improves the quality of as-built information

Resources Required:

• Design models
• 3D coordination software for federating and spatially analyzing models

Team Competencies Required:

• Ability to manage 3D coordination activities
• Ability to manipulate, navigate, and review a 3D model
