What is 5D BIM?
5D BIM is the fifth dimension of BIM.
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:
- 4D BIM with the addition of information regarding the duration of works (time);
- 5D BIM with the addition of material cost information and construction site building tasks.
In addition to 2D and 3D geometrical dimensions, construction phase timing and realization costs also become immediately available.
5D BIM is, therefore, a specific view that exposes project estimate and cost analysis data referring to the BIM model.
BIM Authoring software (Revit®, ArchiCAD®, ALLPLAN®, VectorWorks®, Edificius, etc.) all create a 3D BIM model with a proprietary file format (DWG, RVT, EDF, etc.). 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.
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. 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.
What are the benefits of 5D BIM modeling?
Creating the 5D BIM model by associating costs to the geometric dimensions of the 3D BIM model can turn out to be a great advantage because:
- determining project costs is faster: with 5D BIM it's much easier and faster to detect changes in costs whenever design changes are necessary. In fact, thanks to the dynamic cost estimate updating with each project variation, it's also possible to evaluate cost variations in real time and propose budget changes, even before starting the construction phase;
- cost control is faster and more precise: 5D BIM easily shows the costs of each element directly on the 3D model. The information extracted from the BIM model identifies and quantifies elements in a very precise manner;
- the acquisition of material quantities from the BIM model is direct: with 5D BIM, the detection of material quantities and work processes takes place on the basis of the information provided by the model, avoiding errors and inconsistencies between the cost estimate documents and the digital model;
- save costs and time: greater control and speed of information on costs during the design and execution phase strongly minimize errors and work resources. The integration of the 5D model with time dimension (BIM 4D) allows you to simultaneously optimize project and execution costs with activity timing aspects;
