• Echirolles : a 65 metre-long urban pipe ramming project under the Grenoble ring road
• Brioude : a 140 metre-long HDD crossing to bypass new motorway construction
• Albias : 3 parallel 310 metre-long HDD crossings under the rural Aveyron river
Three projects, all in complex geotechnical and / or geological environments, in which OPTIMUM teams accompanied their clients from the very beginning to the very end of their trenchless projects. These recently completed, diverse gas pipeline projects all highlight the significant advantages in having OPTIMUM’s specialist engineers at the contracting authority’s side to analyse, develop and monitor trenchless projects from their inception (feasibility studies) through to works completion (onsite drilling supervision). A perfect understanding of the project history as well as all relevant geotechnical constraints allow for decisions to be taken quickly and for technical advice and monitoring to be more pertinent, minimizing risks and optimising operations.
Three technical challenges, three project successes.
