Project background and challenges
In view of the planned expansion of the Zurich site, it was essential to have a white model This is an accurate, neutral representation of the existing situation: plot, buildings and industrial infrastructure. More than just a model, it's an evolving document base that can be used to visualise new sites, 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.
Methodology used
- 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. - Data processing
After acquisition, the point clouds were georeferenced, cleaned and assembled. This process guarantees a reliable geometric base for BIM modelling. - 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).
Best practice and sector references
Our approach is based on a proven Scan-to-BIM methodology combined with 3D digitisation, 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.
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.
Thanks to this white modelThe Zurich industrial site now has a scalable, durable support system that can be easily updated as changes are made. Its modular structure, designed from the outset, guarantees great operational flexibility. Whether it's a question of adding new buildings, reorganising spaces or integrating technical data, the model can adapt quickly to requirements, while maintaining its accuracy and compliance with modelling standards.
