ATC Williams Pty Ltd

Singleton, NSW 2330


We have a proud tradition of engineering innovation and technical excellence. Our focus is to align our expertise and service capabilities with our client's needs, strategies and goals, to deliver long term benefits for their project.

Our point of difference is our experience and expertise in our specialised markets, coupled with a strong emphasis on quality. We focus on cost-effective and pragmatic solutions, and prioritise project delivery aligned to our client's needs and expectations.


We began operations in Melbourne in 1981, as MPA Williams and Associates, and subsequently expanded to Perth in 1993. We set up a specialist testing laboratory in Melbourne which became NATA accredited in 1992.

Our business group, Australian Tailings Consultants was formed in 2000 to emphasize our focus on mine tailings disposal and water management strategies. This work became increasingly international, with major projects in places including Iran, South America, and Central Asia.

In October 2011 our operations were further expanded with the successful merger with Allan Watson Associates, which had built a strong business in Queensland also based on tailings, as well as waste and landfill for Local and State Governments. This provided us with a Brisbane office and stronger presence in the Queensland marketplace.

In 2015 we headed overseas to South America. Our growing work in Chile over recent years made a new office in Santiago, Chile a logical step. We further expanded our operations in this region with the addition of a second new office in Lima, Peru to provide increased support to our clients.

Today ATC Williams continues to expand our operations across Australia and in locations around the world


Our people are engineering specialists with expertise in tailings management, geotechnical engineering, slurry transport, water and waste management. Our experience spans over 500 projects in Australia, the Americas, Africa, Europe, the Middle East and Asia.

With a culture that encourages openness and respect amongst colleagues, we have developed enduring relationships and created long-term stability in the team. We are passionate about what we do and foster work environments that are both challenging and personally rewarding. The technically challenging projects that we become involved with also provide exciting opportunities for our staff, which maintains engagement and enthusiasm.

We recognise the contribution our people make to our ongoing success and the many benefits that are achieved for our clients. We are therefore committed to supporting our people with professional development and mentoring, to enable skills development and fulfilment of career aspirations. Today’s working environment is one of constant change. The labour market is extremely competitive in all disciplines. Maintaining a consistent standard of quality and a thriving organisation requires sound operational management and a team that works well together. ATC Williams has had many years of growth and success, and has taken the time to build a solid team. We look forward to continued success for all our people in the future.
