Building Information Modeling
What do we mean by BIM?
There are many interpretations of BIM ranging from a basic 3D model of the architectural elements to a full digital twin of the building including every single element of, and within, the building.
The additional term 4D refers to the phasing of each in chronological order. This allows the creation of video "film" of the buildings virtual progress as well as mirroring actual construction progress.
Adding 5D data includes costing for each element for financial forecasting as well as budgetary and valuation purposes.
The BIM 3D model can also be used for energy forecasting (using real world historical weather data as well as flood defence analysis) , for furniture management etc.
The 3D model is created in a digital environment and may represent a photo realistic model of the actual building.
Behind each element in the model are sets of data linked to the virtual object (say a wall or an air conditioner). These data may be design requirements for performance, physical properties (dimensions, weight etc) , as well as engineering specifications, test results, snag records, maintenance manuals and so on.
By necessity some of these data will be included in the Modeling software to enable visual representation, cost reporting, energy predictions etc to be carried out on the model.
The majority of the data may be more easily managed outside the modelling environment whilst maintaining a link to the model via a unique identifier. In this way many users may interface with the model via handheld devices on site.
