Project Phases and Phased Design

BIM for Architecture, Engineering, and Construction Curriculum


Phased New Construction

Would it be appropriate to create a separate phase named Demolition?

While it is possible to create a separate project phase named Demolition, it is typically unnecessary and confusing to isolate this step. Rather, demolition is typically shown by setting up a phase filter that highlights the elements demolished during a phase. Typically, demolition is a quick process, but if detailed planning of the demolition phase is needed, a separate project phase can be defined.

Why do room objects exist in a single phase and not span between phases?

The properties of rooms (for example, the type and occupancy), as well as the boundaries, often change between project phases. So rooms must be defined explicitly during each project phase to avoid ambiguity or confusion..

Which settings determine whether an element will be displayed in a view in a phased project?

Whether an object is displayed depends on both the properties of the element and the view. For each element the phase created and phased demolished properties determine the existence of the element in any given phase. For each view, the combination of the phase and phase filter properties determines which elements are candidates to be shown. Finally, the graphic overrides determine which of the candidates will be displayed based on each element\u2019s model category.

How can you demolish a portion of an existing wall or building element?

If an element can be split, you can break the single element into parts: the part to keep and the part to demolish. Once split, you can demolish the appropriate part.

What happens when a hosted object is demolished, such as a door or window?

When you demolish a hosted object, such as a door or window, Autodesk\u00ae Revit\u00ae software automatically fills in the opening that was created to host that object. This models real-world behavior. Demolishing a window, for example, typically involves patching the opening with the adjacent wall materials.

How could you apply phases to schedules, which are essentially just another model view?

For example, in a large renovation project, a door schedule would usually list all doors created in the project. In a building with hundreds of doors, the schedule could become difficult to work with because the demolished doors would be listed with the post-renovation doors. It is typically better to create separate pre-demolition and post-renovation schedules by applying the appropriate phase and phase filters to each.
