Cardno Limited, an Australian consulting firm, has acquired ATC Associates, a Lafayette-based environmental services company, in a deal valued at $112 million.

ATC has 1,600 employees and 69 offices in 39 states. ATC’s services include environmental management, industrial hygiene and occupational health, geotechnical engineering, construction materials testing and inspection, and environmental health and safety training.

Cardno Managing Director Andrew Buckley said the addition of Cardno ATC will further strengthen Cardno’s exposure to the U.S. environmental and natural resources management market and is highly complementary to Cardno’s existing businesses in the U.S. He also added that this acquisition confirms Cardno’s position as one of the largest environmental consulting firms in the U.S.
