[Source: ISO/IEC 20944-1:2013(en), modified term – added “building” to specify information about built environment assets, and modified the definition – added ‘built environment asset’ to the definition of Information Management to clarify the specific management of ‘building’ information.]

Note: Within the term, ‘building’ refers to the process of building a built environment asset, not a specific type of facility. BIM is a function that can be implemented across all types of built environment assets, including buildings, bridges, highways, tunnels, process plants, landscape, and other infrastructure and facility types.

Building Information Model

[Source: NBIMS-US™ Version 3, modified – added the word ‘shared’ and added the words ‘and built asset’– see Note 2 and Note 3]

Note 1: NBIMS-US™ Version 3 also included “As such it serves as a shared knowledge resource for information about a facility, forming a reliable basis for decisions during its life cycle from inception onwards.”

Note 2: Added the word ‘shared’ to the definition to be more consistent with ISO/TS 12911:2012(en) definition. The ISO definition uses the term ‘built object’ instead of ‘facility’ and adds facility types including ‘buildings, bridges, roads, process plant’.

Note 3: Added the words ‘built environment assets’ to specify that a building information model can include representations of buildings, roads, bridges, plants, and other built assets.
