They're separate towers founded on separate caissons.

Essentially the entire site has a grid of caissons below. They would be larger diameter below the towers to support the additional loads. Where it is just supporting the parkade, I would think they are smaller diameter. I'm pretty sure this was visible last year when the hole was till open.

Building systems will also be separate. The only thing shared would the parkade ventilation systems. But that's almost a separate building in itself.
