B-Spec reference material
Now that B-Spec has moved to A-SPEC Version 5.
As with all the A-SPEC specifications, start with the A-SPEC Introduction & Overview Requirements document — it covers the shared rules that apply across every data specification, so B-Spec should always be read alongside it.
Together, they'll guide you through compliant data requirements for:
- new subdivision developments
- capital works projects
- projects involving the capture of existing assets
Curious what's changed? Section 6 — Summary of Specification Changes has the full log. Both documents are ready to download now.
Worth knowing:
- These are the current, required versions as of 4 September 2023.
- The updated Code List can be used straight away.
