Terms that come up in every BIM project.
Technical abbreviations without explanation help nobody. Here is what the terms mean and where they matter in a project.
-
AI-ready Building Data
Building data that is georeferenced, classified and interoperable.
-
As-is capture
The metrological survey of an existing building in its current condition.
-
BEP
BIM execution plan: how the project parties meet the requirements of the EIR.
-
BIM Field Control
The ongoing comparison between model and construction state during the build phase.
-
Building Twin
The structured digital building model that forms the basis for operational digital twins.
-
Digital Twin
A digital representation of a real building, maintained and kept current across its entire life cycle.
-
EIR
Employer information requirements: what the client needs in terms of information.
-
Gaussian Splatting
A method that computes a photorealistic, freely navigable view from imagery.
-
Georeferencing
Placing the capture correctly within an official coordinate system.
-
IFC
Industry Foundation Classes: the open exchange format for BIM models.
-
LOG
Level of geometry: how detailed a component is represented geometrically.
-
LOI
Level of information: which alphanumeric properties a component carries.
-
LOIN
Level of information need: the agreed depth of information in a BIM model.
-
Mesh
A triangle network derived from points that represents surfaces as closed faces.
-
Point cloud
The measurement itself: millions of three-dimensional points with coordinates and colour value.
-
Reality Capture
The metrological capture of a real object as three-dimensional data.
-
Scan-to-BIM
The path from point cloud to a structured as-built BIM model.
-
Single Source of Truth
One valid data basis that all parties refer to.
-
Spatial Intelligence
The active use of structured building data by AI models.
