Real-time applications
- Security
Zero accidents ! The most complex operations are managed by Unifield, which alerts operators in the event of danger.
- Lean
Master the production day by day and be alerted in real time of a drop in productivity on the site. Capitalize data to better build future projects.
- Quality
The information is reliable and available at all times by the site team, the methods and the subcontractors to ensure flawless production.

The implementation of the CAD.42 system allowed us to control this height at any time of the day and to prove factually to our client that this constraint was respected at all times.

ZERO INCIDENT in the use of heavy equipment for the Charles de Gaulle Express Mitry site. Industry-intensive production work in the railway environment operated. Monitoring and traceability of all machine movements and all alerts. Reinforcement of the awareness of the actors of the site on the permanence of the railway risks associated with the works. »

From a contractor's point of view, it is a practical solution which is already finding applications on several of our construction sites.

We used the Cad.42 anti-collision assistance system for 8 months on the Orly Station and Parking Silo site. Indeed the space and time constraints of the site oblige us to use one or two additional mobile cranes in the interference zone of our tower crane. The ease of setting up the RTK.42 boxes has met our expectations of speed and efficiency concerning the risk of collision between the different cranes used on the site, the system is a real prevention tool for crane operators (crane tower + mobile cranes).

The real time digital twin from CAD.42 allows us to handle safety issues but also to aggregate data automatically to improve our operations.

The implementation of this solution on site with our partner CAD.42 includes the safety approach in the model in real time. This dynamic digital twin foreshadows the construction site of tomorrow.

Thanks to the CAD.42 ecosystem, it becomes possible to ensure real-time monitoring of the construction site and to bring your digital model/avatar to life. The data thus collected in the field is also used for productivity. The solutions deployed in connection with LEAN approaches make it possible to streamline and optimize business processes.

The CAD.42 automatic progress monitoring tool now makes it possible to validate, without manual action, the progress of worksite tasks. A result made possible by the connection of BIM, the crane, load recognition by machine learning and planning. Some thought about it; we did it !
