Introduction
Phasing is a powerful feature in Autodesk Revit that allows users to manage different stages of a project within a single model. This capability is crucial for projects involving renovation, addition, or phased construction.
1. Understanding Phases
Phases in Revit are used to represent different time periods in a project. Each phase can include new construction, demolition, or existing conditions. The key phases typically used are:
– Existing: Represents the current state of the project site or building.
– Temporary: Represents temporary elements needed during construction but not in the final design.
– Demolition: Represents elements that need to be removed.
– New Construction: Represents the work to be completed in the current project phase.
2. Phasing Settings
Revit allows customization of phases through the Phasing dialog box:
– Manage Tab > Phasing Panel > Phases: Create, rename, and reorder phases.
– Phase Filters: Control how elements are displayed based on their phase status (e.g., New, Existing, Demolished)
– Graphic Overrides: Customize the appearance of elements based on their phase status.
Steps to Customize Graphic Overrides
1. Select the Category to Override:
– Click on the category (e.g., Existing, Demolished, Temporary, New) you wish to customize.
2. Set Line Styles:
– Click the Override button next to the Cut Lines or Projection Lines.
– Choose the desired line style, line weight, and color from the Line Styles dialog.
3. Set Patterns:
– Click the Override button next to Surface Patterns or Cut Patterns.
– Choose the desired pattern and color from the Fill Patterns dialog.
4. Apply and Save:
– Click OK to apply the overrides and close the dialogs.

3. Phase-Specific Elements
Each element in a Revit model can be assigned to a specific phase using the Properties palette:
– Phase Created: Indicates the phase during which an element is created.
– Phase Demolished: Indicates if an element is to be demolished.
This allows you to accurately track the lifecycle of each element within the project timeline.
4. Views and Phases
Views in Revit can be set to display specific phases, which is crucial for creating phase-specific documentation:
– Phase: Determines which phase the view is associated with.
– Phase Filter: Determines what is shown in the view based on the selected phase and filter settings.
These settings help in producing plans, sections, and elevations that correspond to the correct phase of construction.
5. Working with Phases
To effectively work with phases:
– Create Phases: Set up the necessary phases for your project under the Phases dialog.
– Assign Elements: Use the Properties palette to assign the correct phase information to elements.
– Configure Views: Adjust view properties to display the appropriate phase and phase filter.
– Demolish Elements: Use the Demolish tool to mark elements for demolition, automatically updating their phase information.

6. Advanced Phasing Techniques
For more complex phasing requirements:
– Temporary Elements: Use to model temporary structures or systems required during construction.
– Phase Mapping: Useful when linking models that might have different phase settings to ensure consistency.
– Renovation Projects: Combining existing, demolition, and new construction phases to accurately depict the scope of work.
Conclusion
Revit Phasing is an essential tool for managing time-based changes in a project, especially for renovation and phased construction. By properly setting up and using phases, you can ensure that your project documentation is accurate and reflects the intended construction sequence.
