Building a Survey-Based Digital Model - Modelling Rules
To create a 3D BIM model, we are following a precise specifications which defines the specifics of modelling. Here are the main elements of our modelling rules, which we define before starting each project:
- Modelling files: We use Revit (.rvt) or Archicad (.pla) files, depending on the client’s preferences and the project requirements.
- Levels of Detail: We adhere to detail standards such as LOG 300 for geometry and LOI 200 for associated information. These examples are for illustrative purposes only, and we adjust the levels of detail for each project according to specific requirements.
- Accuracy and Tolerance: We «smooth» the point cloud to improve accuracy when converting the laser scan into a digital model. We define the tolerances in advance, such as a margin of ± 5 cm / 2° for distorted or displaced features.
- Organisation by Levels: We divide the elements into levels and place them on the appropriate finished levels. This organisation includes the management of half-storeys and the precise positioning of vertical elements. We must agree on these details before we begin.
- Verification and Georeferencing: We need to determine whether the model will be georeferenced and whether elevations will be verified and specified for elements such as the roof or parapets. We discuss these specifications with the client and agree them before starting the project.
These examples illustrate our standard modelling rules. However, every project is unique. We need to define these parameters precisely before starting work to ensure that the BIM model meets the customer's expectations and the project's requirements, thus ensuring a successful renovation.

The Crucial Role of BIM Modelling in Building Renovation
La BIM modelling is much more than just a technology. It is essential for the renovation and maintenance of buildings. Thanks to 3D digital mock-up BIMEvery architectural and structural detail is accurately captured. This enables effective planning prior to any physical intervention. This method provides an in-depth analysis for renovation projects, guaranteeing flawless execution.
Our Scanning Process for BIM Modelling
We start with a detailed scan of the existing building. We use high-precision laser scanners to capture millions of points. This process creates a dense point cloud, the basis of the 3D BIM model system. This accurately reflects the current conditions of the building and supports facilities management and the planning of renovation projects. 3D modelling of buildings.
Every project we undertake in French-speaking Switzerland benefits from a bespoke approach. We adapt the level of detail (LOD, LOI, LOG) to suit the client’s objectives, whether it is a heritage renovation, a major conversion or a simple compliance upgrade. Our BIM models include not only the precise geometry of buildings, but also useful technical information such as materials, equipment and existing installations. This gives architects a solid basis on which to design, and allows building managers to plan future maintenance with complete peace of mind.
From Capture to Model: Our Detailed Approach
Each scan generates a 3D BIM modelling of the building. It highlights aspects that are often hidden in traditional plans, such as structural irregularities and undocumented previous modifications. This information is crucial for engineers and architects, who play a key role as BIM managers when planning renovations.
Use of ARCHICAD and REVIT in our BIM Modelling Projects
ARCHICAD is at the heart of our 3D BIM modellingbut we are also able to use REVIT to meet the specific needs of each project. This software enables us to build BIM models and facilitate real-time collaboration between all project stakeholders. As a 3D BIM service providersWe use ARCHICAD and REVIT to ensure seamless integration of modifications, immersive 3D visualisation and accurate documentation, all of which are essential for renovation projects.
However, it is important to specify the desired BIM software, whether ARCHICAD or REVIT, when placing the order. This allows us to customise our approach and ensure that the software used matches the expectations and requirements of each customer.
Benefits of BIM Modelling for Project Management
The BIM modelling services offer a number of advantages for managing construction projects. They improve collaboration, optimise resource management and reduce costs through accurate planning. The accuracy of BIM models optimises the purchase of materials, reduces waste and avoids costly delays and construction errors.
Over and above the gains in precision and coordination, the BIM modelling considerably improves communication between the various parties involved in a project. With a single, shared digital model, everyone involved speaks the same language. This data centralisation reduces errors of interpretation and minimises duplication. It also provides better budget visibility, thanks to reliable estimates right from the initial phases. With our BIM services, projects benefit not only from smoother execution, but also from rigorous monitoring that ensures deadlines and costs are kept to a minimum.
