The fast, secure transmission of data is as elementary to modern societies as the supply of power. Here too, SAG carried out the groundwork.

The French SAG subsidiary laid a 350 km long cable route for the country's high-performance fibre optic cable network. The "Artère Fédératrice Départemental de la Moselle" runs predominantly along arterial roads, which necessitates extensive signposting and safety measures as well as the use of special machinery.

The power supply grids in the region are installed mostly underground. Prospecting teams with sensors clear the way for the advancing installation units.
