History
GHD was founded as a private practice in Melbourne, Australia in 1928 by Alan Gordon Gutteridge who operated as a consulting engineer with focuses on water and sewerage. The partnership of Gerald Haskins and Geoffrey Innes Davey joined with Gutteridge's practice in 1939, establishing the formal partnership of Gutteridge Haskins & Davey. During the 1950s and 60s GHD grew to more than 400 employees while expanding into transportation, manufacturing plants, building and civil works, energy, mining and dams. A notable project of the 1960s was the extension of potable water and sewage infrastructure across Tasmania. GHD expanded globally in the 1970s with a joint venture in Malaysia.

During the 1990s GHD expanded its services into architecture, environmental and business consulting while expanding its presence in Southeast Asia. During the 2000s GHD continued to grow through a series of mergers and acquisitions in the US, Canada, Europe, Australia, New Zealand, the Middle East, China, Chile and Malaysia. By 2013 GHD had grown to more than 1000 employees in North America.

In 2014, GHD merged with Canadian firm Conestoga-Rovers & Associates in one of the largest private stock transactions in the engineering and environmental consulting industry, creating a combined company of 8,500 employees. At the time of the merger Conestoga-Rovers had about 3,000 employees mostly in North America and the United Kingdom, while GHD had 5,500 employees across five continents. The combined company became the sixth-largest employee-owned engineering consultancy in the world, with $1.5 billion in combined revenue. Also in 2014, GHD acquired the brand and business of Australian architecture firm Woodhead, later renamed GHD Woodhead.

In 2018 GHD opened a new North American headquarters facility in Waterloo, Ontario. At that time, the company said that the North American region accounted for over half of GHD's  global revenue.

GHD ranks #9 in international design firms operating in the US and #8 in Canada according to Engineering News-Record’s 2021 annual survey of key market segments. 

On 2 April 2024, Jim Giannopoulos was appointed CEO.
