BIM Guide 04 - 4D Phasing

4D models, which combine a 3D model with time, allow project teams to evaluate various time-dependent project concerns, such as project phasing, tenant move schedules, or continuity of agency operations, in an efficient and quick way.  In addition, 4D models, which visually represent these time-related concerns, are highly effective communication tools and can be used to communicate with technical and non-technical stakeholders alike.

GSA evaluates the appropriate use of 4D modeling technologies on a project-by-project basis.  For specific questions, please contact the national BIM program or the appropriate regional BIM champion.
