Proud to have accompanied RTE throughout the Pont VII to Sainville trenchless crossing, now successfully installed. Drilling the curved 240m long HDD under an SNCF freight line in a heavily congested overground and underground environment called for the highest levels of vigilance and expertise.
OPTIMUM worked with RTE during the entire project: from design (G1 PGC, G2 AVP, G2 PRO), to drilling contractor selection (G2 DCE), and finally for the 24h/24h drilling operations (G4), monitoring works around the clock.
Great teamwork with RTE, Bouygues Energies Services, Huré Canalisations, Lynx+ and Arkogeos, ensured that drilling was completed in just one week, limiting the impact on the railway network.
The project is now complete; a great challenge, successfully met.
