In November 2010 Dayton & Knight was acquired by Opus International Consultants’, after which time we became known as Opus DaytonKnight. The company was originally incorporated in West Vancouver, BC in 1965 by Mr. Martin Dayton, P.Eng. and Mr. Gordon Knight, P.Eng. The office was relocated to North Vancouver in 2004. 

Over the years, the company has become a trusted partner in the creation of sustainable communities through the development and management of world class infrastructure. We are proud to be part of the communities we work within and really care about the quality of the work we deliver.

The company has been centered on employing people who are dedicated to enhancing client relationships and who are considered leaders in their areas of specialization. The success of our business is due to our people, who are experienced, skilled and recognized internally and globally.

Opus has a rich history dating back to colonial New Zealand when the Ministry of Works and Development – the government construction agency – was opening up the country’s notoriously difficult terrain with public works, roads and rail. 

The pioneering and ambitious spirit of our early days helped to shape what Opus was to become. It has seen the company evolve from a handful of engineers in New Zealand to a global network of more than 3,000 designers, architects, planners and engineers working across Australasia, the UK, Canada and the United States.   

Opus has 40 offices in New Zealand, 18 in Australia, 12 in the UK, and 16 across Canada and the US.
