BIM (Building Information Modeling) is a way of working with a digital model of a building or industrial hall in which every element (wall, pipe, machine) carries information about its position, dimensions and properties. The model serves design, construction and operation.
What a BIM model contains
Unlike a point cloud, BIM is not just shape but structured data: the model knows what a wall, switchboard or pipe is, how large it is and which category it belongs to. The open IFC format, standardised as ISO 16739, is used for data exchange and allows the model to be opened in different programs.
Use in operation and energy management
BIM is used for asset management, maintenance planning, refurbishment and equipment records. In energy management, meters and consumption data can be linked to model elements, so it is clear where each thing is measured. Such a connected model is referred to as a digital twin of the hall.
Example from manufacturing
A simplified model of walls, floors and main distribution systems is created from a scanned production hall. Switchboards and meters are then linked to it. When planning a new line, the model can be used to verify both the location and the connection.
Frequently asked questions
What is the IFC format?
An open standard for exchanging BIM models between programs (ISO 16739). A model in IFC can be opened regardless of which program it was created in.
Do I need BIM if I have a point cloud?
A point cloud is enough for measuring and checking the as-built condition. BIM pays off when you want to work with elements as data, for example for asset management and linking to metering.
