ISO 19650
The international standard series for managing information across the whole life of a built asset using BIM.
ISO 19650 is the international standard series that sets out how information is organised, produced and exchanged on a project that uses Building Information Modelling. Rather than prescribing software or geometry, it defines a process: who specifies what information, who produces it, how it is reviewed, and how it is handed over — so that information becomes a managed, predictable deliverable instead of a by-product of design.
The series is published in parts. Part 1 sets out the concepts and principles; Part 2 covers the delivery (design and construction) phase; Part 3 covers the operational phase of an asset. It introduces a clear language of information requirements and of parties — an appointing party (the client side) and appointed parties (those delivering information) — and it places a common data environment at the centre of every exchange.
ISO 19650 grew out of the earlier UK BS 1192 and PAS 1192 standards and effectively internationalised them. For practitioners it is the backbone that ties together the BIM execution plan, the level of information need and the controlled states a deliverable moves through — the structure the rest of this glossary builds on.
