BIM just shuffles the problem around. There are firms that do "one source of truth" BIM models but the real issue is conflicts and workflow buy in.

How do you get architect to agree with engineer with lighting designer with lighting contractor when they all have different non overlapping deadlines, work periods, knowledge and scope?

edit: if you don't work in the industry, BIM helps for "these two things are in the same spot", but not much for code unless it's about clearance or some spatial based calculation

BIM definitely helps, but most projects still rely heavily on 2D PDFs for coordination and permitting especially in the US. Even when BIM exists, drawings often lag behind the model and changes don’t stay perfectly synced. We see AI plan checking as a bridge that helps teams catch what falls through the cracks in today’s workflows. And BIM only catches certain issues not building codes etc.
