Definition
Building Information Modelling is a way of working in which the project is built as one 3D model where every element carries its data: material, size, quantity and phase. All disciplines share it.
Why it matters on a project
It catches clashes between structure, HVAC and plumbing before construction and takes quantities straight from the model instead of manual take-off.
Common mistake
Calling any 3D model BIM, when the point is that it carries data that can be extracted and coordinated.
Frequently asked questions
Does a villa project need BIM?
Not necessarily, but it helps on large villas with dense services, to catch clashes and extract quantities.
Which software is used for BIM?
Revit for modelling and Navisworks for clash detection are the most common, with IFC for exchanging models.
