I was going to say, I don't understand what this does that Revit doesn't already do better. I guess it's a fun demo, but I doubt this was a problem that needed solving.

The plans are the input here, not the output. The AI prepares cost estimates. It isn’t responsible for what is getting built.

So basically you built an estimation wrapper ready to use - without any guarantees whatsoever? Someones still needs to double-check? why is that different than other LLMs

Estimation is by definitely not final. Did you watch the demo? It’s a workflow tool.

You can trivialize anything like this, salesforce is just a Postgres wrapper, doesn’t mean it’s not valuable.

That's because it's been used in the construction industry for literally a couple of millennium (e.g. ancient rome) and it's a fairly well-understood material. The variations come in with the newer "exotics" rated above 5k psi that are more chemistry than aggregate, water, and portland cement.

Did your one class teach you that any non-parabolic concrete cross section is approximately 7% steel? And that the bidding issues with concrete are centered around the steel rebar/wwm/wwf installation and formwork/earthwork prior to pour?
