In general: where are requirements mapped in the IFC?

Beside the important question “where are requirements mapped in the IFC?” in current BIM practice I would like to sketch a target bearing for future BIM developments:

In the light of actual research on decentralised common data environments and linked building data
(e.g. https://www.researchgate.net/publication/335947234_Towards_a_Decentralised_Common_Data_Environment_using_Linked_Building_Data_and_the_Solid_Ecosystem)
I see the possibility of a long-term shift

  • away from BIM as 3D “drawing” job for planners
  • towards BIM as building model evolution with multi-stakeholder approach
    Along the whole supply chain we have to handle the legal aspect of contract law.
    Offer and acceptance are legal basis for correct fulfillment of a contract.
    During a building projects evolution we face several statements with different degrees of binding force:
  1. ideas
  2. wishes
  3. proposals
  4. concepts
  5. requirements
  6. promises
  7. confirmations
  8. fullfillment claims
  9. fullfillment contestations
  10. measurement results from project parties (non-neutral)
  11. measurement results from referees (neutral)

Currently this information can be collected in IFC files but I would not recommend.
In the long-term systematic requirements-engineering based on the industrial V-model are promising.
