Source-backed reporting and analysis connected to the companies, capabilities, authorities, and operating domains it affects.

AIA A201 keeps construction workflow authority in the contract

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.

IFC 2024 keeps interoperability version-specific

Schema version, model view, entities, properties, geometry, validation, and exchange evidence must be named before an IFC claim becomes useful.

Machine-readable information requirements can improve model checking only when project adoption, responsibility, source models, exceptions, and acceptance remain explicit.
