White mock-up: digital base for an industrial site in Zurich

The creation of a white model A faithful, uncluttered model of the Zurich industrial site provided our client with a precise 3D support, designed as a working basis for planning extensions, documenting production lines and the gradual evolution of the site. This minimalist model provides a reliable basis for managing future transformations with complete control.

At 3D Scan Bat, we carry out this type of white models from high-precision 3D laser surveys, guaranteeing a faithful reproduction of the existing structure. Our teams, based in Martigny and Nyon, use Leica RTC360 and BLK360 scanners to capture every detail, then convert the point cloud into a BIM model. This approach provides the customer with reliable digital support that can be used immediately in Archicad, Revit or AutoCAD. The white model becomes a strategic planning tool, designed to evolve with the industrial site and support its transformation in a gradual and secure way.

La white model offers the client a global and neutral vision of the industrial site, without the distractions of textures or colours. This uncluttered rendering allows the client to concentrate solely on the volumes, scale relationships and layout of the buildings. It is a strategic tool that facilitates communication between technical teams, management and external partners, while providing a solid basis for decision-making.

  • To support the expansion of an industrial site in Zurich, we created a 3D white model based on a complete laser scanner survey. Each building was modelled separately and then integrated into a master file, providing a scalable basis for planning, production line documentation and future site management. 3D printing available on request.

Project background and challenges

In view of the planned expansion of the Zurich site, it was essential to have an accurate, neutral white model of the existing situation: plot, buildings and industrial infrastructure. More than just a model, it is an evolving document base that will enable us to visualise new locations, internal modifications and the layout of equipment.

As part of this project, the white model was not just a visual aid, but a real management tool. It was used to identify the areas available for setting up new units, to anticipate the constraints linked to the existing infrastructure and to prepare the stages of the works. This proactive approach reduced the risk of errors, optimised planning and facilitated coordination between the various trades working on the site.

Another major asset of this white model lies in its ability to centralise technical information. By structuring data according to a defined LOD, everyone involved - architects, engineers or production managers - can work on a common, consistent basis. This homogeneity reduces differences between disciplines and improves communication between teams. What's more, the modularity of the model means that the site can be segmented by zone or by building, simplifying analysis and future updating. As a result, the customer has a long-term tool that is ready to integrate new data on an ongoing basis.

Methodology used

  1. High-precision 3D surveying
    On each zone of the site, surveys terrestrial laser scanner were used to generate a dense point cloud with millimetre precision and without manual interpretation.
  2. Data processing
    After acquisition, the point clouds were georeferenced, cleaned and assembled. This process guarantees a reliable geometric base for BIM modelling.
  3. Conversion to white model (Scan-to-BIM)
    The point cloud is transformed into BIM model monochrome with no superfluous textures: the volumes, roofs, walls and networks are rendered in the form of a single colour. white model structured, in accordance with the LOD standards defined with the customer

Working with the technical office

Throughout the project, we worked in close coordination with the plant's technical office. Together, we :

  • defines the level of detail required (level of development or LOD),
  • validated the intermediate stages of the model,
  • put in place sustainable processes to ensure that the model is regularly updated.

Deliverables provided

Our client received :

  • A white model in BIM format (IFC or Revit), representing the existing state of the site.
  • Export 2D plans, sections, elevations and technical challenges documenting the buildings.
  • Associated metadata, making it easier for in-house teams to use.

Uses and benefits for the customer

  • Analysis and planning simulation of extensions, future layout, integration into the production chain.
  • Clear communication The minimalist rendering of the model makes it easy to analyse without distraction.
  • Scalable base The white model is designed to be enhanced in the medium term with technical layers (machines, networks, maintenance).

In addition to planning, the white mock-up is also a useful tool for continuous monitoring tool. It makes it possible to archive the site's development, easily compare what already exists with future projects and document each transformation. This digital traceability guarantees better control of investments and improved communication with all stakeholders.

Best practice and sector references

Our approach is based on a proven Scan-to-BIM methodology combined with 3D scanning, offering speed, reliability and savings (up to 30-40 % compared with traditional surveys). These processes guarantee modelling that complies with the best standards for complex industrial projects.

As part of this Zurich project, our methodology also enabled us to deliver intermediate exports validated in close collaboration with the customer's technical office. Each stage was checked to ensure compliance with operational and regulatory requirements. For example, we incorporated specific sections and elevations requested by the engineers responsible for maintenance. This customisation ensures that the white model is not just a visual rendering, but a technical and documented working tool that can be used directly for the day-to-day management and strategic planning of the industrial site.

Outlook for development

In the long term, the white model forms the basis of a truly scalable digital twin, carefully structured to meet your customer's future needs. Each building has been modelled in a independent fileThese models are then grouped together in a centralised master file. This modular organisation offers a number of advantages:

  • it makes it easier to manage updates: a building can be documented or added to without affecting the rest of the model,
  • the files are lighter, so quicker to load and easier for the technical teams to handle.

This makes it possible to periodically update the condition of buildings, enhance the information in the production linesThis modular structure means that the digital twin can be gradually upgraded in line with the customer's real needs. This modular structure means that the digital twin can be gradually upgraded according to the customer's real needs, while ensuring that upgrades are managed in an optimised, agile and secure way.

Option: 3D printing of the white model

Although the model delivered is primarily for digital formatWe also offer the possibility of a 3D printing of the white model to scale. This represents a tangible and educational addition, ideal for visualising the site in its entirety. The main benefits are :

  • an immediate physical view of the layout, useful for coordination meetings or presentations;
  • the possibility of experimenting with different versions (before/after extension) by printing variants;
  • easy to reprint after modifications: thanks to the adjustable digital file, a new version can be produced without having to start from scratch

In short, 3D printing complements the digital mock-up: it makes the model more concrete and accessible, while remaining faithful to the principle of "design by design". white model minimalist and structured.

A white model is a simplified, monochrome 3D model of a site or building, used to faithfully represent the volumes without textures or superfluous details. It is used in particular for planning, technical documentation and anticipating extensions.

The white mock-up provides a reliable geometric basis for planning extensions, documenting production lines and monitoring changes to the site. It offers a clear, modular and scalable view, useful for engineers and management alike.

Working with independent files for each building, grouped together in a master file, makes it easier to update, simplifies the models and allows each building to be managed independently, while maintaining a coherent overall view of the site.
