I suppose I may be in uncharted territory here.
All based upon local codes and ordinance I am sure. I assume that I can
use sonotubes with a traditional foundation depth and place the pilings
on top. I suppose that my only wonder is the spacing of the pilings
now. Here the rule of thumb is 4 pilings per 100 square feet, 6 per 200
etc...
