Information Model consisting of connected but distinct individual Information Models. 
A model is federated when two or more of the discipline models are electronically shared into the architectural model in order to:
- show context; supporting documentation and views of the design intent
- perform analyses;
- provide other visual comparisons; and
- to verify proper integration and coordination of its subsystems with each other.
A federated model is a model management technique that enables limited computing resources to cope with the increasing complexity, fine levels of detail, and higher Levels of Development needed to represent the built environment. When reviewed and clash detection is performed, then the model is the basis of the Design or Design Intent model and construction documentation is derived from this federated model.
