Before ISO 19650, the UK's approach to BIM, known as BIM Level 2, was defined by a set of British Standards and Publicly Available Specifications. ISO 19650 was developed from them, so their ideas, and many of their terms, live on. Older contracts, templates and project documents still refer to them.

What stayed the same
- The common data environment with work-in-progress, shared, published and archived states.
- Field-based naming of containers.
- The BIM execution plan as the delivery team's response.
- The MIDP and TIDP.
- Information requirements flowing from the client's needs.
Why it still matters
- Many organisations' standards and templates were written to PAS 1192 and have not been fully updated.
- Some public sector contracts and frameworks still cite it.
- The ideas are the same, so experience with PAS 1192 transfers directly; the vocabulary is what changes.
