Overview

Liberty Industrial was engaged by McConnell Dowell to remove onsite assets damaged during the cyclone season at the Groote Eylandt wharf located southwest of Nhulunbuy township in the Northern Territory. Removal of the damaged asset and remediation of the area will make way for rebuilding the wharf.

Challenges

Unexpected and fast execution required to assist the client immediately.
Our client McConnell Dowell required swift project execution with tight project delivery timelines.
