The main difference between the traditional approach and 5D BIM modeling is the speed with which the cost of the project can be updated and changed. With the open and standard IFC format, it is possible to add information relating to the bill of quantities directly to the 2D/3D model produced by any IFC-Certified software. In addition to 2D and 3D geometrical dimensions, construction phase timing and realization costs also become immediately available.ĥD BIM is, therefore, a specific view that exposes project estimate and cost analysis data referring to the BIM model.īIM Authoring software (Revit ®, ArchiCAD ®, ALLPLAN ®, VectorWorks ®, Edificius, etc.) all create a 3D BIM model with a proprietary file format (DWG, RVT, EDF, etc.).

5D BIM with the addition of material cost information and construction site building tasks.

4D BIM with the addition of information regarding the duration of works (time).

The geometric model is usually in 2D or 3D, but by adding further information we can also obtain additional views that relate to the BIM model:
