The contract is for the last of the three main onshore packages and puts the project, which may eventually feed the planned Iran LNG facility, back on track after a delay of more than a year.
Daelim leads a group that also includes three Iranian engineering and construction giants — Sazeh Consult, Kayson and Iran Industrial Networks Development Company (IIND).
Daelim is the second South Korean company this year to take on a billion-dollar-plus project in Iran at a time when Western companies are staying away because of political risk factors.
