Building information modelling (BIM)
The use of a shared digital representation of a built asset — its geometry, properties and related documents — to support design, construction and operation decisions with reliable information.
Common data environment (CDE)
The agreed single source of information for a project or asset, used to collect, manage and share each information container through a controlled workflow of states, statuses and revisions.
Federated model
A combined model assembled from separate discipline or package models, each of which remains owned and maintained by its author.
Industry Foundation Classes (IFC)
An open, vendor-neutral data schema for describing buildings and infrastructure — their elements, properties and relationships — published by buildingSMART and standardised as ISO 16739-1.
Level of detail
How much graphical or geometric detail a model element shows. As a project-wide numbered scale it has largely been replaced by level of development and level of information need.
