Best Practice ? - Multi-story project

[Anonymous]

I have a question about exterior walls for multi story projects.

I have a 12 story condo I am working on and would like an opinion as to how
I approce the exterior walls. Should I place individual walls from level to
level or should i place one wall from 1st level to the roof? Not all levels
have the same floor to floor height so I thought that one wall from the
ground and attached to the roof would work well.

Are there any drawbacks to this approach?

Thanks,
Mark

how are you approaching the interior/core vs the exterior/shell?

if the shell will be one model that is ~ independent of floor content, one wall makes more sense, but has some potential problems still.

if each floor has an impact on it's shell, then having individual walls means you can edit it's shell w/o monkeying with someone else working on another level.

in *general* i've found that walls/curtains that are their own entity should be one unit, where as walls/curtains that are working with a floor should be floor to floor.

now, depending on how they're being constructed, you may need/want to group several floors together, i.e. a precast first 2 floors with a studs higher up, you'll want the precast as one unit (possibly as individual walls per piece of precast)

in short, we need a lil more info on materials, and how things work.

The condo project is a 12 story post tensioned concrete frame structure with
CMU exterior walls. These CMU walls sit on the edge of the concrete frame.
These walls are floor to floor walls, not a continuous wall the entire
height of the building.

I guess my question is would modeling the condo be easier to have one
continuous exterior cmu wall that is attached to the 1st level and the roof
level, even though it interesects the concrete slab,,or should i have
seperate exterior cmu walls at each level.

You can assume that all the levels are the same layout and i would be the
only person working on this project since i am the only one in the office
diving head first into Revit.

Thanks for you input,
Mark

I've found it is always best to model things the way that they're actually constructed. If the CMU is between slabs, then model it between slabs. I'd use a stacked wall in your case, that way it will still behave as a single wall.

Thanks for your help.

Unless there are changes in the exterior wall perimeter from floor to floor or wall thickness, material or material widths, then I would opt for a wall 12 stories tall. The only other consideration would be material take-offs and I wanted to itemize each floors walls for the same reasons as listed above.

I would model it as a single wall all the way up, and join geometry at the
slab to visually cut the wall at each level. It will be much easier to
manage the shell if it is modeled with fewer elements, unless you have some
other reason to model each separately (scheduling/takeoff requirements,
material changes, etc).
