Glossary of terms – BIM
Following on from our series of articles on Building Information Modelling (BIM), we have produced a glossary of terms and key acronyms to help guide you through the various levels and documents involved in BIM.
Glossary of Terms and Acronyms used in BIM

Core Maturity Model
Model used within BS 8541 to define levels of BIM as follows:
0 – Unmanaged CAD probably 2D, with paper (or electronic paper) as the most likely data exchange mechanism
1 – Managed CAD in 2 or 3D format using BS 1192:2007 with a collaboration tool providing
a common data environment, possibly some standard data structures and formats. Commercial data managed by standalone finance and cost management packages with no integration
2 – Managed 3D environment held in separate discipline “BIM” tools with attached data. Commercial data managed by an ERP. Integration on the basis of proprietary interfaces or bespoke middleware could be regarded as “pBIM” (proprietary). The approach may utilise 4D programme data and 5D cost elements
3 – Fully open process and data integration enabled by IFC/IFD. Managed by a collaborative model server. Could be regarded as iBIM or integrated BIM potentially employingconcurrent engineering processes
Data Drops
A level of data as yet undefined that will be the output from the BIM process at various stages. RIBA have identified data drops at stages B, C, E, G, K and L
