Qumrud off to good start

The 18km long third section of the Qumrud water conveyance tunnel in Iran has been making good progress since SELI launched its 4.5m diameter Wirth TBM earlier this year. Up to 39.4m has been claimed as the maximum daily advance.

There are three local contractors working independently on the Qumrud works: Peymab Company for the first 9km of tunnel, Stratous Company for the second 9km stretch and Qurb-e-qaeem Company for the last 17.75km. SELI is the sub-contractor for tunnelling on the Qurb-e-qaeem section.
