In the case of crossing continuous foundations, the program conservatively designs each of those foundations for the full column reaction. Since each was designed for the full load it's probably OK. More on that here: communities.bentley.com/.../8147.ram-ss-foundation-faq

In the case of an intersecting spread footings, or spread footings intersecting continuous footings, the program determines the soil bearing pressure for each in a vacuum, so potentially you could overburden the soil where the footings intersect. A small overlap like this may be fine, especially if the design was controlled by something other than soil pressure, but of course you'll have to find a way to detail it for the contractor.

Note, in either case, Ram Concept can be used along with a mat foundation (perimeter modeled in Ram Modeler) to check the combined foundation with any plan geometry in a more sophisticated way.
