Sedgman managing director Mark Read said repairs and work on the project had restarted since the site was assessed as safe.

“Although work has recommenced, the potential impacts as a result of the earthquake are still being assessed in anticipation of further ongoing delays due to widespread damage to essential transport infrastructure and disruption to supporting supply chains,” he said.

Sedgman won the $A50 million CHP contract for the Bocamina power station expansion project last year.

The 8.8-magnitude earthquake was further than 100km from the location of the project in the coastal city of Coronel.
