Encardio-Rite has supplied several geotechnical instruments for the Line 16 and Charles De Gaulle Express metro tunnels, which are a part of the prestigious Le Grand Paris Express Metro Project.
The project involves a public transportation network plan consisting of four metro lines around Paris, along with the expansion of two existing lines. The four lines consist of Lines 15, 16, 17 and 18. The 26 km long Line 16 extends Line 15 and gives access to the more remote suburbs in the northeast of Paris, 75 km long underground Line 15, around the edge of downtown Paris and connecting all the closest suburbs. The metro lines are planned to open in stages between 2022 and 2030.
The tunnel monitoring instruments supplied included thousands of in-place inclinometer sensors, strain gauges, pressure cells, and load cells.
