BIM HUB
Understand BIM before you buy it
Everything on this page is explained the way we would explain it across a table: no jargon for its own sake, no software sales pitch.
TOPICS
What you can learn here
BIM Basics
- What BIM actually is, in plain language
- BIM vs CAD: why the model matters more than the drawing
- Who uses a BIM model on a project
- Common myths about BIM cost and effort
Levels of Development (LOD)
- LOD 100: concept mass and early feasibility
- LOD 200: generic elements with approximate sizes
- LOD 300: accurate geometry for construction documents
- LOD 350: interfaces between systems modelled
- LOD 400: fabrication and installation detail
Coordination & Clash Detection
- How a federated model is assembled
- Hard clashes, soft clashes and workflow clashes
- Reading a clash report without special software
- How clashes are closed and signed off
Revit & Tools
- Revit for architecture, structure and MEP

- Naming conventions and file structure
- Model health checks before issue
- Handover formats: RVT, IFC, NWD, DWG, PDF
BIM on Site
- Using coordinated drawings during execution
- Quantities and material planning from the model

- What to ask your BIM consultant during construction
GLOSSARY
BIM terms in one line each
- BIM
- Building Information Modeling — a 3D model where every element carries data such as size, material and type.
- LOD
- Level of Development — how much detail and reliability a model element carries at a given stage.
- Clash detection
- Automatically checking whether elements from different disciplines occupy the same space.
- Federated model
- Several discipline models linked together into one coordinated view of the building.
- IFC
- An open file format for exchanging BIM models between different software.
- BBS
- Bar Bending Schedule — a table of reinforcement bars with shapes, lengths and quantities.
- Take-off
- Quantities of material extracted from the model for costing or ordering.
- Family
- A reusable Revit component such as a door, window or column with its own parameters.
