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;

To get all the advantages of the 5D BIM methodology, use PriMus IFC as your 5D BIM software.

Selecting entities in the BIM model | PriMus IFC | ACCA software

Selecting at least two BIM model entities , PriMus IFC automatically identifies all other similar entities too...

To associate the identified work sections or job types with the entities to be accounted for, PriMus IFC offers three advanced methods of automatic and customized selection::

  • you can select - with simple entity clicks on the BIM model - at least two entities and the software automatically identify all similar entities
  • you can define additional and specific customized conditions, which cause the software to identify and highlight the relating items
  • to finish, you can manually identify each individual entity to be associated with the job type, and therefore proceed to a proper accounting process.

Define measurement rule | PriMus IFC | ACCA software

Define the measurement rule (applying predefined templates or creating new ones)

Once you have identified the entity type, create the measurement rule containing the descriptive and metric information that the BIM software will apply to compose the quantity take off.

These the necessary instructions on the basis of which PriMus IFC will automatically perform the quantity take off.

But that’s not all! The measurement rules action (entity + work section or job type + measurements) created for a single project can be saved as model or as template (set of multiple models) and reused in any other similar project.

Automatically get quantity take off for project entities | PriMus IFC | ACCA software

Automatically get the quantity take off for all project entities

Once the measurement rule has been defined, or a previously saved model or template has been chosen from your archive, PriMus IFC automatically applies it to other similar conditions too, quickly returning a detailed quantity takeoff for the entire project.

Visually check the correspondence between quantity take off and the 3D BIM model entities.

Once the General Data has been defined, you can print the quantity take off, export it in Word, Excel or in the DCF format of PriMus. You can also save the project on the usBIM.platform cloud to share it and collaborate with your work team.

Update dynamic quantity takeoff | PriMus IFC | ACCA software

Get a dynamically updated version of the quantity take at each revision of the IFC model

If the quantity surveyed project has undergone modifications and revisions or is subject to further development, just import the updated IFC file.

PriMus IFC automatically calculates all the entities that respond to the measurement rules (entity + job type + measurements) previously defined with the effect of obtaining an automatic update of the quantity take off to the new design condition.

Also, in this case the visual control on the 3D model, allows you to verify any added entities too.

Create quantity takeoff template | PriMus IFC | ACCA software

Create quantity take off models and apply them on any other project

Another great advantage that PriMus IFC offers is the opportunity to reuse previously created measurement templates provided with the software.

After having "delevoped" an automatic quantity take off, the software allows you to save it as a measurement model and reuse it on other projects instead of starting from scratch, and without necessarily choosing reference Price Lists.

Select one or more models from your archive, apply them to the project and automatically generate the quantity takeoff for the entities corresponding to the model selection criteria; by choosing a template, you get the quantity take off including multiple work sections or job types.

With PriMus IFC you have a built-in IFC BIM Viewer to open and view IFC files of 3D virtual models from any BIM authoring software such as Edificius, Revit®, ArchiCAD®, Allplan®, Tekla®, VectorWorks®, etc. You can also:

  • load multiple IFC files in a single view, to simultaneously view all the design aspects in an integrated manner: architectural, structural, MEP designs, etc.
  • navigate the 3D virtual model in a simple way thanks to the standard Zoom, Rotation and Pan functions.
  • view the 3D model with different colours by type of element and define the transparency of the objects to also view the internal portions of a 3D model
  • explode and decompose the BIM model by plane, both along the vertical axis and along the horizontal axis
  • explore all IFC properties, including setting custom filters and selection groups
  • view all the properties and information assigned to each element of the virtual 3D model such as volumes, areas, surfaces, distances, weights, etc.
Recognition classification of the project | PriMus IFC | ACCA software

Recognition classification of the project

PriMus IFC allows you to identify, within the IFC file, the classifications composition with which the project was formely made (UniClass 2015, OmniClass, MasterFormat, etc.). In this way all the information is cataloged and managed, and therefore is easily available.
A classification is a set of information (cataloged and managed) aimed at identifying specific activities and work processes; this information, shared among all the operators in the sector of competence, allows to uniquely identify a specific entity.
With PriMus IFC, and the function of recognizing and displaying the classifications associated with the entities of the IFC project, it becomes even easier to identify the entities to be accounted for in the quantity takeoff.

WBS Work Break down Structure | PriMus IFC | ACCA software

Structured breakdown of the quantity takeoff (WBS - Work Break down Structure)

During the definition of the measurement rules, PriMus IFC allows you to define WBS structures with an unlimited number of levels.

Once the project structure has been "broken down" to the desired level, you can assign individual voices or blocks of measurement entries to the WBS structure.

Export quantity takeoff in standard formats | PriMus IFC | ACCA software

Export of the quantity takeoff in standard formats

PriMus IFC saves the quantity take off in the PriMus standard DCF format and exports to the Word DOCX file format and Excel XLSX file format.
