Phase Planning

(4D Modeling)


A process in which a 4D model (3D models with the added dimension of time) is utilized to effectively plan the phased occupancy in a renovation, retrofit, addition, or to show the construction sequence and space requirements on a building site. 4D modeling is a powerful visualization and communication tool that can give a project team the including owner a better understanding of project milestones and construction plans.

Potential Value:

  • Better understanding of the phasing schedule by the owner and project participants and showing the critical path of the project
  • Dynamic phasing plans of occupancy offering multiple options and solutions to space conflicts
  • Integrate planning of human, equipment and material resources with the BIM model to better schedule and cost estimate the project
  • Space and workspace conflicts identified and resolved ahead of the construction process
  • Marketing purposes and publicity
  • Identification of schedule, sequencing or phasing issues
  • More readily constructible, operable and maintainable project
  • Monitor procurement status of project materials
  • Increased productivity and decreased waste on job sites
  • Conveying the spatial complexities of the project, planning information, and support conducting additional analyses

Resources Required:

  • Design Authoring Software
  • Scheduling software
  • 4D Modeling Software

Team Competencies Required:

  • Knowledge of construction scheduling and general construction process.  A 4D model is connected to a schedule, and is therefore only as good as the schedule to which it is linked.
  • Ability to manipulate, navigate, and review a 3D model.
  • Knowledge of 4D software: import geometry, manage links to schedules, produce and control animations, etc.
