Hyder Consulting is a multi-national advisory and design consultancy with particular specialisation in the transport, property, utilities and environmental sectors. The firm employs approximately 4,200 people across the UK, Europe, Germany, Middle East, Asia and Australia and has been listed on the London Stock Exchange since October 2002. The name Hyder is the Welsh word for "confidence".[1]

As of October 2014 Hyder Consulting is part of Arcadis NV.


The firm was responsible for the design of projects such as the Victoria Falls Bridge (1905), the Sydney Harbour Bridge (1932), the Forth Road Bridge (1964), the Severn Bridge (1966), the Bosphorus Bridge (1973), the Humber Bridge (1981), and the Fatih Sultan Mehmet Bridge (1988). Other notable projects included the Parkes radio telescope (1961), the Erskine Bridge,[2] the 46m Algonquin Radio Observatory (1965), and Melbourne's West Gate Bridge (1978).[3]

The eminent consulting engineering practices that went on to form Hyder Consulting were John Taylor and Sons with origins from 1739, Freeman Fox and Partners, founded in 1857, and Sir Bruce White Wolfe Barry and Partners with origins from 1856. The first two long-established practices merged due to common interests in 1987 becoming the Acer Group, with Sir Bruce White Wolfe Barry and Partners joining the Group in 1991. Over the next few years, several smaller specialist firms were incorporated to form a worldwide infrastructure and civil engineering consultancy.

The company and another consultant Wallace Evans Ltd were acquired by Welsh Water in 1993 and renamed Hyder Consulting in 1996. When Hyder Consulting was bought by Western Power Distribution, the senior management of Hyder Consulting instigated a management buy-out, completed in January 2001. The firm then listed on the London Stock Exchange in October 2002.

Notable projects[edit]

Hyder has been delivering iconic landmark projects in over 100 countries for over two centuries.[citation needed]

As lead designer for several lots on the London 2012 Olympic Games, the company’s contribution to its third Olympics was varied. Works involved extensive earthworks, environmental and remedial work for the northern half of the Olympic Park site, lead design and environmental works to the Broxbourne White Water Canoe Centre for the slalom races, and a complicated route network system that saw transport routes being reversed or diverted around events including the running and cycling marathons.

Taiwan’s High Speed Railway was the largest civil engineering undertaking, when it opened in 2007, with Hyder as lead designer for two sections involving complex construction planning. The line carries over 44 million passengers a year on the 345 km of north-south rail link. Hyder also worked on the new Berlin Hauptbahnhof station which can handle 100 million passengers annually.
