Co-ordinated Building Index (CBI)

The classification and coding system for the New Zealand construction industry.

CBI classification is a numeric based system, owned by Construction Information Limited (CIL).
As a consistent fixed numbering system, it is used for collating and referencing technical clauses in their Building Contract Specification system named Masterspec.


The Masterspec subscription service is used by over 1,000 NZ building design consultant offices. We have therefore adopted it for cataloging and file naming of our revitcynosure resources. We recommend you adopt a similar system for your private computer filing use.
