Drilling 20m below the busiest railway in Normandy calls for the highest levels of vigilance and expertise. By accompanying RTE’s trenchless project in Harfleur on a daily basis and assisting drilling operations around the clock, OPTIMUM ensured the railway network was preserved throughout.
• Continuous monitoring of drilling operations by dedicated engineers, present on site 24 hours a day.
• Validation of execution documents
• Enhanced security mechanisms (continuous monitoring of the rail platform and topography)
The expertise of the dedicated project engineers enabled this curved, 260m long HDD crossing to be drilled on time despite adverse geotechnical conditions. The crossing is now complete; a great challenge, successfully met.
