History

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 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.
