Excellent example.
You can see from the construction photos of Modello how the podium has an entirely almost column free floor layout in the interior spaces (not surprisingly used for office space) since most of the mass of the slabs and the structure is being carried by the structural concrete skin....
Other than some slab band and transfer beams on the ground floor with a few columns the entire podium structure is supported by the concrete on the skin.
Easier to pull off with a podium of a few floors (and in an office use-type structure).
Much harder and trickier to do with the main stem of a 40-50 storey residential highrise tower where high wind shear forces, seismic considerations and seismic bracing come into play.
Additionally, in Modello, I imagine having that heavy concrete skin structure on the podium level facing the skytrain line helps cut down some of the noise from the trains passing by every so frequently.
And you're not really losing that much in terms of views being lost from less window and visibility opening area.
