All you need to do is associate the project costs to the 3D dimensions of the model and, with each variation of the project, the relating cost estimate or BoQ is continuously updated.
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.).
