Open Standards

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

IFC support is not a lossless handoff verdict

buildingSMART maintains Industry Foundation Classes as an open, vendor-neutral schema for built-environment information. A provider claim still needs release, model-view, field, identity, relationship, validation, and round-trip evidence for the project exchange.

PMBOK Eighth Edition guides delivery—not contract authority

PMI's current guide adds updated principles, performance domains, and non-prescriptive process guidance. It can organize project-management practice, but it does not change the owner, contract, law, or professional authority governing a construction decision.

ISO 19650-2:2018 remains current while its revision stays draft

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 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.

IDS turns selected BIM requirements into checkable records

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