- BCF (BIM Collaboration Format)SoftwareAn open format from buildingSMART for exchanging model-based issues — with viewpoints, comments and element references — between BIM tools.
- BEP (BIM execution plan)WorkflowsThe delivery team's plan for how it will meet the client's information requirements — people, process, standards and tools.
- CDE (common data environment)WorkflowsThe agreed source of project information, with a workflow that moves containers through work in progress, shared, published and archived.
- Clash detection types (hard, clearance, duplicate)WorkflowsThe three main kinds of clash test, what each finds, and how tolerances change the results.
- COBieStandardsConstruction Operations Building information exchange — a structured format for handing over asset information to the people who run the building.
- Coordinate reference systems and EPSG codesBIM + GISWhat a CRS is, the difference between geographic and projected systems, and how EPSG codes identify them.
- EIR (exchange information requirements)WorkflowsWhat the appointing party needs from an appointment — which information, when, in what form and why.
- GeoreferencingBIM + GISPlacing a model in a real-world coordinate reference system, so it lines up with surveys, GIS data and other models.
- IDS (Information Delivery Specification)StandardsA buildingSMART standard for writing information requirements as a machine-readable file that software can check IFC models against.
- IFC (Industry Foundation Classes)SoftwareThe open, vendor-neutral data model for exchanging building and infrastructure information between software.
- Information container namingStandardsHow ISO 19650-style file and container IDs are built from fields and codes, and what does not belong in the name.
- ISO 19650 overviewStandardsA plain-language map of the ISO 19650 series — what each part covers and how it shapes a BIM project.
- LOD levels (100–500) explainedStandardsWhat LOD 100, 200, 300, 350, 400 and 500 mean in practice, with a simple example for each.
- LOD vs LOINStandardsLOD grades how developed and reliable an element is; LOIN defines the exact information a purpose needs.
- MIDP and TIDPWorkflowsThe delivery plans that say who will deliver which information containers, and when.
- Model checkingWorkflowsRule-based checks of model quality, information and coordination — from naming and structure to clashes and required properties.
- Model federationWorkflowsCombining discipline models into one coordinated view while each team keeps ownership of its own model.
- OmniClassClassificationA North American classification system with numbered tables for entities, spaces, elements, work results, products and more.
- UniclassClassificationThe UK's unified classification system for the built environment, organised in tables for everything from complexes to products.
