Bearing Capacity of a Pier and Pad Foundation.
Bearing Capacity of a Pier and Pad Foundation.
(OP)
Does skin friction of the pad come into play increasing bearing capacity? Can we add the skin friction provided the sides of the pad to the bearing capacity of the foundation?

You're supposed to ignore skin friction near the bottom anyway (in the case of drilled shafts, 2 diameters), due to the 'downdrag' effect of the bearing load on the surrounding soil. I don't know about how your geotech info was presented, but what we get is adjusted based on the size of the footing to account for that effect.
In short, OG's response of a flat "NO" is correct, but for more reasons than just uncertainty about future conditions.
