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

100% agree the hardest problems are workflow and incentives, not file formats.

Even with a perfect BIM model, late changes and discipline silos mean drawings still diverge and coordination issues sneak through.

We’re trying to be the “safety net” that catches what falls through when teams are moving fast and not perfectly in sync.
