Ensuring quality in industrial construction is more important than ever - especially since the introduction of the Building Quality Assurance Act (Wkb). At the same time, construction costs are rising, pressure on the housing market is increasing, and the need for acceleration and sustainability is growing. The challenge is clear: more good homes in the short term, without making concessions to lasting quality.
Digitization and robotization accelerate this transition, but also make it necessary to make every step in the industrial construction process demonstrable and verifiable. Smart dossier creation with Vision solutions play a key role in this. By structurally securing files with Vision cameras, this transition is not only faster, but also more reliable and sustainable.
Since the introduction of the Building Quality Assurance Act (Wkb) on Jan. 1, 2024, contractors are required to demonstrate that a structure meets the agreements made, quality standards and legal requirements. This applies to new construction projects in the lowest risk class (consequence class 1), such as single-family homes and smaller commercial properties. Under the new system, builders must provide a completion file, which includes drawings, calculations and statements from the quality assurance agency. This obligation makes structured dossier formation very important - not only for compliance with the law, but also for transparency towards clients and municipalities.
With smart filing via vision technology, the precast industry is taking a step toward fully traceable, visually supported production.
Filing in industrial construction means automatically and systematically photographing all relevant information about a construction project during part production. After each step in the production process, a vision camera automatically takes a picture of the workpiece.
This creates a visual file for each section that includes:
This part of the final construction file is essential for both the client and the municipality. It helps demonstrate that the structure complies with contractual agreements and construction regulations.
The photos captured with vision solutions provide the visual basis for completion, offer transparency, support quality control and can be used in any disputes. Even after completion, the file remains valuable - for example, for maintenance, renovation or inspection of the structure.
In modern prefab production, it is no longer enough to just know what there was made - you must also be able to demonstrate what and when it is made. Therefore, vision cameras placed above work tables and linked to a digital interface platform. The high-resolution vision cameraare mounted in an inspection cell or above a production line. The camera automatically captures images with extreme detail accuracy at every step in the construction process, revealing even minor discrepancies.
Each recording is automatically given a timestamp, so that each manufactured part in the production process can be easily retrieved and verified. The images are stored for audits, quality reports and form a visual log of the production process. Thanks to the Integration with MES or ERP systems process monitoring is also possible, contributing to traceability and efficiency.
During the production process, the operator goes through a series of digital instructions. One of those steps is: "now take a picture". At that point, the camera takes a picture of the workpiece - for example, of a mounted socket or an applied insulation layer.
These visual recordings are proof that work has been done correctly. The images are stored directly in the digital product file of the precast element. This creates a visual log of each step in the process, which allows quality, traceability and compliance be made demonstrable.

The images captured by vision cameras during the production process are automatically stored in a digital product file. This file is managed via a cloud-based platform or a local server environment, depending on the organization's IT architecture.
To secure the data, the following measures are applied:
Encryption (encryption): Images are stored and transmitted encrypted to prevent unauthorized access.
Access Management: Only authorized users (such as quality controllers, project managers and clients) can access the file through role-based permissions.
Backups and redundancy: Regular backups ensure that data is not lost in case of failures or incidents.
Audittrail: Every change or access to the file is logged, ensuring transparency and traceability.
Integration with existing systems: The file can be linked to MES or ERP systems, making it part of the broader quality and compliance chain.
This approach ensures that visual filing is not only efficient, but also secure and reliable.
When a step in the visual filing process is skipped - for example, because a photograph was not taken or not saved - a gap in the traceability of the production process is created. This can affect delivery, quality control and compliance with regulations such as the Building Quality Assurance Act (Wkb).
To prevent this, several safeguards are in place:
If a step is still missing, it can be highlighted in the file and possibly supplemented with a manual explanation or additional inspection. This keeps the file usable and transparent.
Yes, clients can look into the digital product file - provided they are authorized to do so. Through a secure environment, they can access visual and technical documentation of the production process, such as:
This transparency offers several advantages:
Access is controlled through role-based permissions in the platform so that only relevant information is visible to the right people.
