Whether you are a team leader, TBM pilot, mechanic or a worker, and whatever your company, these training courses are made for you!

Providing between one and three days of theoretical and practical training, our facilitators can train six to 10 people in a single session. Our goal is to ensure that sites have a high level of service and expertise by providing them with organisational flexibility specifically adapted content and safety/performance values.

This is particularly the reason why we pay special attention to ensuring you are trained by experts, who have worked on site and who alone have over 40 years’ experience in the construction of hundreds of kilometres of tunnels all around in the world.

This mobile platform can be brought to you in a container and training sessions can be organised on your worksites.

More than 250 people have so far been trained by our experts. Several courses are already planned on the Horizon’s worksites (packages T2A and T3A) of the Grand Paris Express and in Saint Jory.
