Appendix B-10: BIM Use: 3D Control and Planning (Digital Layout)
3D Control and Planning (Digital Layout)
Description:
A process that utilizes an information model to layout facility assemblies or automates control of equipment’s movement and location. The information model is used to create detailed control points aid in assembly layout. An example of this is the layout of walls using a total station with points preloaded and/or using GPS coordinates to determine if proper excavation depth is reached.
Potential Value:
- Decrease layout errors by linking model with real-world coordinates
- Increase efficiency and productivity by decreasing the time spent surveying in the field
- Reduce rework because control points are received directly from the model
- Decrease/Eliminate language barriers
Resources Required:
- Machinery with GPS capabilities
- Digital Layout Equipment
- Model Transition Software (what software takes the model and converts it to usable information).
Team Competencies Required:
- Ability to create, manipulate, navigate and review 3D model
- Ability to interpret if model data is appropriate for layout and equipment control
