Summary

ISO 19650-1:2018 establishes the conceptual framework for BIM-based information management. It defines key roles (appointing party, lead appointed party, appointed party), the Common Data Environment (CDE), information requirements (OIR/AIR/PIR/EIR), and the iterative information delivery cycle. Reviewed and confirmed in 2024.

Defines the concepts and principles for managing information through the whole life cycle of a built asset using Building Information Modelling (BIM). Foundation document for the ISO 19650 series.

Practical Notes
! ISO 19650-1 sets vocabulary — every other ISO 19650 part assumes you've read this one
! OIR / AIR / PIR / EIR is the most-referenced concept hierarchy in tender documents
! The CDE state diagram (WIP→Shared→Published→Archived) is the practical heart of the standard
! India has not published an IS equivalent; Indian projects reference ISO 19650 directly

Key Clauses
Cl. 3 — Terms and definitions (asset, project, information container, CDE, EIR, BEP)
Cl. 4 — Information management principles (asset and project information models)
Cl. 5 — Hierarchy of information requirements: OIR → AIR → PIR → EIR
Cl. 6 — Information delivery cycle: 8 stages from need to acceptance
Cl. 7 — Roles: appointing party, lead appointed party, appointed party
Cl. 8 — Common Data Environment (CDE) and information container states (WIP/Shared/Published/Archived)
What is the difference between OIR, AIR, PIR, and EIR?+
OIR (Organisational Info Requirements) is what the asset owner's business needs. AIR (Asset Info Requirements) is what's needed to manage the asset in operation. PIR (Project Info Requirements) is what's needed to deliver the project. EIR (Exchange Info Requirements) is what each appointed party must produce at each delivery milestone. Hierarchy: OIR → AIR → PIR → EIR.
Is ISO 19650 mandatory in India?+
No. As of 2026 there is no Indian Standard (IS) on BIM and no national mandate to use ISO 19650. Many Indian projects voluntarily reference it because international consultants and global clients require it.
