Do small margins necessarily mean there is no chance for disruption? I think structural engineering and architecture both have voids that tech can fill. Alot of the work is tedious, repetitive, and begging to be automated.
The Finite Element Analysis software is widely available. Constructability, judgement, client relations, dealing with budget, proposals, and rfis, etc are totally different.
I think you've picked some creative fields but haven't actually identified voids to fill. What are you offering that S-Frame or Revit isn't? What drudge work in particular do you think you can tackle that no one else has?
If you can identify some specific voids to fill, go ahead. but I think those voids you identified are likely your unfamiliarity with the industry.
But if you've got something, go for it. Just research first, because right now it sounds pretty nebulous.
