The role of precast concrete panels can be ambiguous; sometimes they are load bearing, sometimes they are a wall, sometimes they are a decorative element, sometimes a combination of these.
To complicate matters Revit does not have a separate category for precast concrete panels.
Because of this there are a number of different ways precast panels can be modelled, each with their own limitations and benefits.
There are some factors that need to be considered before deciding which method to use:
How is the model divided up; will panels be on a separate linked file or workset to the room enclosing wall behind them (e.g. Facade workset).
What strategy will you use to put doors and windows into panels.
Will panels be scheduled, and how; only by type, or individually.
Will the structural engineer want to monitor their location.
How complicated are the panels; how much more complicated are they likely to get.
How important is detail at this stage of the project; plan to change the method you use as project detail increases.
Are there panels with different purposes, and should different methods be used for each; back of house load bearing versus decorative.
METHODS TO CREATE PRECAST CONCRETE PANELS
Examples of these methods of creating precast conc walls are in a Revit project file in:
S:\Revit Libraries\Approved Library\Walls
called: Walls PRECAST CONC-ANT.rvt
This folder also contains pre-cast conc panel components.
