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:
- ideas
- wishes
- proposals
- concepts
- requirements
- promises
- confirmations
- fullfillment claims
- fullfillment contestations
- measurement results from project parties (non-neutral)
- 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.
