Building information modelling
Shared 3D models carry data across design, construction and operation.
In depth
BIM creates parametric 3D models with data (quantities, schedule 4D, cost 5D, operation 6D) shared via common data environments (IFC, Revit, Navisworks). Benefits: clash detection, coordination, fewer errors, better handover and facility management.
Key points
- LOD levels
- Open BIM
- Digital handover
ExampleClash detection finds pipes crossing beams before construction.
What is Building information modelling?
Shared 3D models carry data across design, construction and operation.
Why is it important to understand building information modelling?
Building information modelling shares data across the whole life of a building, so coordination errors are found before they reach the site.
What is BIM?
A process that uses shared digital models with data about the building, so teams can design, build and operate with the same information.
What are the benefits of BIM?
Earlier clash detection, better cost and schedule control, and a useful model for operation and maintenance.
How is Building information modelling used in practice?
Typical applications include detecting clashes between ducts and beams in a 3D model before construction, using a model to plan the sequence of work on a complex project and handing over a building model with data for facilities management.
What should I learn before Building information modelling?
Study "Construction safety" first (topic 106 of 112 in Civil & Structural). It covers the groundwork this topic builds on.
What are the key points of Building information modelling?
LOD levels. Open BIM. Digital handover.
Can you give an example of Building information modelling?
Clash detection finds pipes crossing beams before construction.
What comes after Building information modelling?
The next topic is "Green buildings and sustainability", which builds directly on this one.
How difficult is Building information modelling?
It is classed as Advanced in Civil & Structural (topic 107 of 112). It is an advanced topic. It assumes you are comfortable with the intermediate topics in Civil & Structural.
