Hall has been engaged to undertake maintenance dredging at Ba River to mitigate flood risks and prevent damage to nearby communities during flood events.

Ba River experiences substantial sediment build-up caused by erosion in its upper catchments, and as a result, tropical rains and cyclones pose significant flood threats.

The project involves dredging over 373,000m³ of sands and silts over approximately 3.6km to deepen the river to around three metres below mean sea level.
