Completion this week of an important phase of RTE\u2019s Envision project with the successful installation of a 130-metre-long microtunnel near Arras in northern France.<\/p>\n
Within the framework of the project owner\u2019s network extension, the DN1200 microtunnel now passes under both the Paris \u2013 Lille highspeed railway tracks as well as the 6-lane A1 motorway, two of the country\u2019s busiest transport links.<\/p>\n
OPTIMUM have worked on the project since its infancy, from the initial feasibility studies to the microtunnel design, the contractor selection phase and now the supervision of construction works.<\/p>\n
Tunnelling through chalk between 8 – 10 metres underneath the railway tracks called for the highest levels of vigilance and continuous monitoring of the railway platform ; dedicated OPTIMUM engineers were onsite 24h\/24 during this critical and delicate part of the operation.<\/p>\n
Great preparation and cooperation enabled the works to be completed ahead of schedule ; congratulations to everyone involved : @ RTE, SADE TS, Socotec Monitoring.<\/p>\n
