In 2006 WorleyParsons entered the South American market through a joint venture with Santiago-based ARA, a leading base metals and infrastructure engineering firm, and Colt Companies, Canada's largest engineering and project services firm, became part of the WorleyParsons family in 2007.[10] Later that year, the companies Patterson Britton and Partners, and John Wilson and Partners, were acquired, both consultants in the water and environmental services market in Australia, with specific capabilities in the coastal and marine, water resources and waste water, environmental, civil and structural and power markets.
