“In Catenda Hub the construction company and I were able to exchange, develop and manage all the site adaptations related to the work for which I am in charge of. The 3D has a really virtuous effect on the project. I appreciated the fact that some particularly complex provisional phases, such as the passage of the tunnel boring machine through the station, were modeled in the model. This allowed us to ensure that the progress of the station was compatible with the temporary structures allowing the TBM to slide through. In general, the fact that we could navigate autonomously in the constantly updated digital model, easily find the different technical open points and the decisions taken, well traced in a transparent way in the platform, enabled us to improve the quality of the relationship between the contractor and the project manager. In short: Catenda Hub and 3D have progressively become the new normal in the daily management of the construction site!”
