As part of RTE’s French-UK interconnection project, the dual trenchless crossing in Frénouville is now finished. Both 140 metre-long, 10-metre-deep, HDD crossings, passing under one of Normandy’s busiest rail routes, required precision control at every stage.
OPTIMUM assigned specialist engineers from the document validation phase through to works completion, ensuring round the clock monitoring on site, day and night.
Finalised in April 2020, the project was not only completed on time and in compliance with strict SNCF requirements, but also whilst preserving the health and safety of the dedicated engineers who worked despite the Covid-19 pandemic.
