Our unique capability in dams engineering has been achieved through diversity in project delivery around the world.

— Our Expertise

Engineering Services

Construction of embankments to provide containment for mine tailings or water management application. We have designed and constructed dam embankments with heights of up to 200 m, utilising soil and rock construction materials, with geosynthetic and other unique membrane lining systems, which highlights the diverse technical capability of our team.

Our Dams Engineering team provides high-calibre expertise for any project, with capability in the full range of dam construction types.

Dam break and failure impact assessment is an important part of the dam design process, supporting assessment of inundation extent, population at risk analysis and Consequence Category assessment for any setting. ATC Williams has state of the art capability for undertaking dam break analyses for both Newtonian and Non-Newtonian fluids.

CLIENT
Mangoola Coal Operations Pty Ltd
LOCATION
Wybong, NSW
Mangoola Coal Operations, located in the Hunter Valley, is a major open-cut mining operation committed to responsible resource management and progressive rehabilitation. As part of its closure planning, the site required a comprehensive capping solution for two decommissioned tailings dams: TD1, with a capacity of 3,400 ML, and TD2, with a capacity of 3,900 ML. The Stage 2 capping works covered an area of approximately 222,000 m2.
