BIM Modelling Service for Building Renovation

Located in French-speaking Switzerland, our company specialises in BIM modelling services for existing buildings. We create BIM models and 3D building models. As experts in BIM modelling in Nyon and Martigny, we also offer our services in Geneva. We use advanced technologies to convert building surveys into digital BIM models models. These models facilitate the management and implementation of complex renovation projects in cantons such as Vaud, Geneva, Neuchâtel, Valais, Fribourg, Jura, Bern and Zürich.

La BIM modelling that we offer at 3D Scan Bat is always based on precise 3D measurements taken with a laser scanner. This data is used to generate accurate digital modelsadapted to demanding renovation projects. Our team masters every stage, from capturing the point cloud to creating BIM models that can be used in Archicad or Revit. This gives architects, technical offices and property managers reliable tools for analysing existing buildings, anticipating constraints and planning sustainable interventions. Thanks to this method, your projects will be clearer and more efficient.

Building a Survey-Based Digital Model - Modelling Rules

To create a 3D BIM modelwe 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 file : We use Revit (.rvt) or Archicad (.pla)to suit customer preferences and project requirements.
  • Levels of Detail : We comply with retail standards such as the LOG 300 for geometry and LOI 200 for related information. These examples are indicative, and we adjust the levels of detail for each project according to specific needs.
  • Precision and Tolerance We 'smooth' the point cloud to improve accuracy when we convert the laser survey into a digital model. We define tolerances in advance, such as a margin of ± 5 cm / 2° for deformed or offset elements.
  • Organisation by Level We cut the elements into levels and place them at the appropriate finished levels. This organisation includes the management of semi-storeys and the precise positioning of vertical elements. We need to agree these specifics before we start.
  • Verification and georeferencing We need to determine whether the model will be geo-referenced and whether the altitudes will be verified and indicated for elements such as the roof or acroteria. We discuss these specifications with the client and validate them before launching 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 tailor-made approach. We adapt the level of detail (LOD, LOI, LOG) depending on the customer's objectives, whether it's a heritage renovation, a major conversion or a simple 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.

Understanding Levels of Detail in the BIM Model

The transition from a simple 3D model to a BIM modelling can sometimes seem complex. This complexity is often due to the different levels of detail (LOD, LOG, LOI) that need to be managed. The difference between 3D mock-ups and BIM modelling is explained in depth in the dedicated article : To BIM or not to BIM, 3D model or BIM?

. In reality, for each project, the architect is free to define or exclude certain levels of detail according to specific needs. Visit BIM is more a methodology to be adopted. It focuses on the exchange, collection and documentation of information. This framework ensures that everyone involved knows exactly what rules to follow. In this way, BIM becomes a flexible system rather than a fixed, restrictive framework.

A fundamental aspect of our BIM modelling services is the management of levels of detail: LOD (Level of Development), LOG (Level of Geometry)and LOI (Level of Information). These levels are essential to guarantee the accuracy and reliability of the BIM building models in our projects.

  • LOD (Level of Development) Defines the degree of development of the elements of the BIM model at different phases of the project. This ensures that everyone involved understands the reliability and completeness of the information.
  • LOG (Level of Geometry) Specifies the geometric accuracy of the elements in the model. This precision is essential for realistic visualisation and for predicting space conflicts.
  • LOI (Level of Information) The depth of integrated non-graphical information. It includes details such as material properties and cost estimates, enabling decisions to be made based on reliable data.

Collaborative and Sharing Methods in bim 3d

The success of a bim 3d project depends on effective collaboration between the various stakeholders. Although our focus is on data acquisition by lasergrammetry and the BIM modellingWe do not offer specific services for collaborative methods. However, these methods are crucial for demonstrating the benefits of BIM.

  • Dedicated online platforms They enable BIM files to be shared, tasks to be coordinated and communication to take place in real time. They also offer features such as version management and 3D visualisation.
  • Collaborative working models They allow several users to simultaneously modify the BIM modelThis facilitates coordination and the rapid resolution of conflicts.
  • Integration with other tools BIM can be integrated with planning, cost management and performance monitoring software. This ensures smooth coordination of all aspects of the project.

Using these methods, the 3D BIM modelling can overcome communication and coordination challenges. This ensures efficient execution and successful delivery of projects.
