BIR, on behalf of Orange, has successfully pulled a DN500 HDPE tube containing 15 fibre optic lines. The technical urgency of the project arose at the end of January 2020 as the need to divert a sensitive network installed in a precarious dam became apparent.
OPTIMUM mobilized teams to deliver a complete engineering study, from determining the bore path to supervising the geotechnical surveys and sizing the final tunnelling works, all in a record 4 months and during the Coronavirus crisis.
Despite the urban location and the considerable environmental challenges, the team completed this fully curved, 185-metre-long HDD crossing, on time and on budget.
