Le contexte

Colas, the world leader in road construction, wants to facilitate and modernise the daily work of construction managers through digital mobility. For this, it is necessary to reduce the administrative burden as much as possible, in order to optimize their working time and to respect contractual commitments.

Notre solution

BAM has proposed an application that allows site managers to centralize all the data necessary for the latter. The application in React Native and Node.Js for the backend is available on 3 platforms (mobile, tablet, desktop) to meet all the use cases of the site manager.

Facilitate the daily lives of construction site managers

With Chantier 360, site managers now benefit from a unique product, to keep and complete their activity logs and thus have real-time monitoring of the evolution of their site. The digitization of activity logs results in an increase in Colas' operating margin.

Adapt to the existing system

The Chantier 360 project is part of a complex environment, linked to the Colas structure (60,000 employees in 50 countries). Deploying a new tool therefore had to meet both the field requirements and the technical context of Colas.

Create an adapted and used tool

To convince site managers of the usefulness and benefits of Chantier 360, it was necessary to involve them throughout the project. The quantitative tests carried out every two months allowed us to react quickly to the feedback and new needs of these users, and the weekly qualitative tests allowed us to re-prioritize the roadmap as needed. Direct telephone exchanges with the site managers allowed us to create a product that perfectly meets their expectations.

The project has been a success, we've kept our promises, initial feedback has been positive and the quality has been top-notch. On the BAM side, I saw people who mastered their subject, as they did on the steering committees. You take a step back to adapt, and that's your strength compared with other companies that aren't involved in continuous optimization. I appreciated the fact that you were out in the field, so understanding and analyzing usage is really key, whereas it's complicated to communicate with the business side.
