What does BIM mean?

BIM (Building Information Modelling) is a method in the construction industry based on the creation and use of digital 3D models.

Thanks to these models, a building can be managed efficiently throughout its entire life cycle – from planning to demolition.

BIM modelling is used to create virtual 3D models of a building that contains all relevant information for the entire life cycle of the project. This includes design, planning, construction, facility management and eventually dismantling.

BIM is an interdisciplinary process in which architects, engineers, owners, service providers, facility managers and other construction professionals are involved at every stage. Collaboration is its focus.

Unlike conventional CAD programs, however, BIM goes beyond the mere creation of 3D models: it also integrates extensive data such as cost information, safety data, maintenance and energy consumption data.

Technical building management (TBM), technical facility management (TFM) or technical property management are often used synonymously.

What is BIM software?

BIM is not an application or software in itself. The BIM method is a procedure in which all information about a building is being collected and processed in a digital model.

BIM software provides the technology to create, edit and visualize these digital models.

What functions does BIM software offer?

BIM is known for its multi-layered functions. We present the 9 most important functions this technology has to offer:

1. Modelling of building data

One of the main features of a BIM program is recording, managing and presenting building data in a 3D projection.

2. Visualization

A BIM model creates realistic 3D visualizations and animations that allow a building to be viewed and presented from different angles.

3. Simulation

BIM modelling software has the ability to simulate and analyse different scenarios, such as lighting conditions, energy consumption or design changes.

Did you know? BIM simulation is particularly interesting for structural calculations, as it enables to realistically simulate the structural reaction of a building under certain load conditions, e.g. an earthquake.

With 4D BIM software, it is possible to visualize the construction project progress through a so-called 4D construction process simulation.

In order to do this, the steps of the construction process are depicted in an animated 3D visualization. This forms a link between the individual components of the 3D model and the corresponding activities that are required to put these parts together within the construction schedule.

4. Clash detection

BIM software identifies where different elements of the model may overlap or conflict with each other. This allows issues to be identified and solved at an early stage.

If building components such as ventilation ducts and supporting structures are precisely planned, maintenance can be carried out much more efficiently and smoothly.

5. Scheduling

BIM allows construction and maintenance schedules to be created, managed and adjusted directly within the model itself.

This helps to determine the workload for various tasks and thus supports better personnel resource planning.

6. Cooperation

With BIM software, project participants can cooperate and exchange information in real time.

BIM objects, i.e. the components that make up a BIM model, are intelligent. Which means they possess a geometry and save information. When an element is changed, the BIM software updates the model to reflect this change.

In this way, the model remains consistent and coordinated throughout the entire process, making BIM an excellent tool for collaboration in teams with different professional backgrounds.

7. Integration

BIM enables easy integration and data exchange with other software systems, which improves the workflow between various phases of a construction project.

A common, internationally recognised standard is needed to ensure this open data exchange.

All leading manufacturers use IFC. Which stands for “Industry Foundation Classes”. It’s an open, ISO-certified standard that can be used by any software manufacturer.

8. Sustainability analysis

Some BIM programs contain tools for evaluating the energy efficiency and other aspects of a building’s sustainability. These are particularly relevant for the design and management of smart buildings.

9. Facility management

BIM software supports facility managers in maintaining and managing the building after construction. This phase includes tasks such as tracking maintenance schedules, energy consumption data, etc.

The maintenance and servicing of buildings presents a particular challenge. Wowflow’s intuitive solution is specially tailored to the needs of facility management teams. Learn more here!

BIM software for modern facility management

Although Building Information Modelling (BIM) has become the standard in the construction industry, its potential is not yet fully utilized in facility management.

BIM leads to the simplification of maintenance and repair work and can be a crucial tool for construction cost control in facility management.

Another advantage of 3D modelling in facility management is improved space management.

BIM technology enables integration into currently used CMMS. In combination with other tools, such as reliable facility management software, you can get the most out of your building.

Wowflow’s innovative facility management software can be optimally combined with BIM technology. Learn more here!

What to look for in good BIM software

We present 6 reliable approaches to selecting a powerful BIM software.

1. Define your project requirements

Before you start using BIM software, you need to define the requirements of your project precisely.

This includes identifying specific characteristics of your project, including its size, complexity and the level of cooperation you require.

The benefits of BIM are evident in projects of all sizes. However, they are particularly noticeable in extensive construction projects.

There you benefit immensely from functions such as collision detection, cost tracking and scheduling.

Small to medium-sized companies can benefit immensely from Wowflow’s facility management software solution. Learn more here!

2. Evaluate the skills of your team

Take a close look at the existing skill set of your team.

If your team members are already familiar with a particular BIM software, it could prove more cost-effective and time-saving to continue on using that software.

However, if you are ready to train or hire new talent, this will expand your software choices.

With Wowflow, you don’t need expensive, time-consuming training. You can get started in just one week! Learn more here!

3. Check the various functions


Check whether several users can work on one model at the same time (multi-user). If the work is spread across multiple locations, ensure that the project team can work on the model at any time, regardless of location.

Data format

Check whether the software supports exporting in the IFC format.

The ability to export and import in IFC format should be one of the main criteria when selecting a new BIM program.

On the website of Buildingsmart, the official organization behind the IFC standard, you will find a list of certified programs that support IFC export and import.

Compatibility and integration

To ensure seamless, efficient project execution, it is essential that the BIM software you choose integrates smoothly with your existing software and hardware infrastructure.

Do you use CAFM or ERP software?

Test whether the software can be harmoniously combined with your current tools, such as CAD programs, project management software or building management software.

Functions checklist
  • IFC export/import
  • Support of other exchange formats
  • Multi-user capabilities
  • Integration into other applications
  • Open API for automation and creating your own extensions

4. Pay attention to the softwares performance

In the later stages of the project, the BIM model can be so detailed that this has an impact on program performance. A useful performance indicator you can easily check is the average file size of a project.

Performance checklist
  • The software can work efficiently with larger or complex projects
  • The software can efficiently process large models with a high level of detail

5. Check the 3D model and change management efficiency

As your central source of information, the 3D model should be easy to create, modify and distribute. As already mentioned, the BIM model has to be gradually enriched with more and more data.

In addition to the basic object information such as its profile, material and fire resistance class, it is important that the software offers the option of creating new properties and allows assigning them to objects in a simple manner.

Because changes during planning occur constantly, the program should help you to introduce corrections without any issues.

Each time model corrections are made, you should also be able to check and update the changes in drawings or reports generated from this model.

3D model and change management checklist
  • Add your own information to objects within the model
  • Intelligent adaptation of affected drawings, reports and other documents after model data is changed

6. Make sure that the data can be converted

BIM software collects all kinds of information. However, the collection of data is only the beginning. Next, you must ensure that you can evaluate and analyse this information and use it to generate statistics.

This will allow proactive actions to prevent recurring problems from happening again. The model should enable precise identification of such problems.
