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.
- • 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
- • Design Authoring Software
- • Scheduling software
- • 4D Modeling Software
Team Competencies Required
- • Knowledge of construction scheduling and general construction process.Â 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.
