Great to have accompanied Teréga during the extensive Mont – Ogenne project in southwest France, a key step of which was completed a few days ago thanks to great teamwork and some pretty impressive equipment !
• – Two parallel 500-metre-long HDD crossings, DN650 and DN160, under the Gave de Pau river, each using a double intersect to ensure hole stability in the gravelly ground conditions
• – A fully curved 150-metre-long AVN1200 microtunnel under the Luzoué river
• – Four additional auger boring crossings under rivers and roads
Optimum provided specialist trenchless support for all these crossings, from project conception and engineering design, through soil investigations, to works supervision and monitoring for the duration of the drilling / tunnelling, allowing the project to be completed on time and on budget.
Congratulations to the teams from Teréga, Denys, Catalana, Jamme Kleber, for this great achievement.
