SECTOR

Resources & Energy

CLIENT

BHP – Coal Operations

The GS1 Tailings Dam has undergone considerable erosion on the southern embankment in recent years
and remediation is required to prevent further risk or hazards. A first for BHP, AE Group constructed a
buttress bench to eliminate potential wall failure.

Project Challenges

Working on a LIVE TSF required our construction program for sequencing and timeframes to be on point. Due to the
nature of TSF’s walls and potential failures, our team safety completed the project adhering to stringent health, safety
and design protocols.

The successfully construction of a buttress bench and remediation works, AE Group have been able to minimise further
potential risks and deliver a cost-effective solution whilst increasing BHP’s social value.
