CBI (Co-ordinated Building Information)

CBI is classification system for construction related works.  Originally based on the Common Arrangement of Work Sections methodology it has proven to be an effective classification system widely used for organising resources spanning across office libraries, specification, tendering, estimating, and now BIM.

CBI is the basis of the structure used for the Masterspec specification system.
