« What i really liked about this project was the interaction with the client. It was a very rich experience. »

Jhensy Vally – Designer

« I did the project follow-up meeting with the client every Tuesday on a weekly basis. In terms of key figures, we spent quite some time on the project. For the project management, I personally spent about 350 hours. It was a project that allowed me to grow. We completed the project on time, we met the needs of the client by respecting the specifications that had been communicated to us despite the difficulties on site and despite the health crisis. We respected our commitments. »

« It was an interesting project because we had never had this scenario. Our customer wanted to have his own splicing box. We had to pull cables between the CELESTE splicing box and the Lumen splicing box. It was a great challenge and a very interesting project professionally and humanly. »

Mohamed Charfeddine – Construction manager

« We also reviewed the expected requirements in terms of splicing, where we achieved 0 10, which is a very complex value to achieve even with good welders. So we had to invest in equipment and know-how to achieve our goals. The Lumen project has been a total succes and allowed us to look for new projects of this same type to increase the capillarity of CELESTE network and seek new customers. »
