What is the BIM cost model?

Could you please elaborate on the BIM cost model? I'm curious to know what it entails and how it is utilized in the field of finance and cryptocurrency. How does it differ from other cost models, and what are its key advantages? Is it a widely adopted approach, or is it still relatively new and emerging? Additionally, are there any potential challenges or limitations associated with using the BIM cost model? Thank you for your time and consideration.
