As the lead office of the IG Engi, we are managing the project to structurally reinforce the Engigalerie on the A9 Simplon national road.
In June, a mudslide hit the structure and led to the national road being closed for a week. The Federal Roads Office (FEDRO) has entrusted our consortium with the project planning and construction management of the immediate measures to reinforce 150 m of the gallery.
The main measures include strengthening the gallery ceiling and the back wall
