ISO still lists the 2018 delivery-phase information-management standard as published and current, but under revision, with a draft replacement in development. Project requirements should name the adopted edition instead of silently treating the draft as controlling.
AIA describes A201 as general conditions used with an owner-contractor agreement to govern project administration. Software can route communications, changes, payments, claims, and closeout, but only the project's adopted documents and authorized roles give those records contractual effect.
The standard's modular structure starts with owner requirements, carries them into staged BIM execution planning, names BIM uses, and connects delivery to information exchanges. A model in a platform is not evidence that the contracted chain was completed.
Information requirements, states, review, authorization, acceptance, responsibility, and exchange are the operating system behind a common data environment.
Machine-readable information requirements can improve model checking only when project adoption, responsibility, source models, exceptions, and acceptance remain explicit.
