Dutch engineering group Arcadis is dumping the legacy brand names of acquired companies in favour of a single brand strategy.


Names such as Hyder Consulting, EC Harris and Langdon & Seah are being phased out.  Architectural brands Callison and RTKL are to be merged to create the single name Callison RTKL.

UK chief executive Alan Brookes said the rebranding would “help provide a clarity and consistency of approach to our clients”.

Group chief executive Neil McArthur said: “Building on the rich heritage of the excellent firms that have joined Arcadis and our leading Design & Consultancy positioning, the refreshed brand reflects Arcadis’ ability to seamlessly draw on our global capabilities to provide exceptional and sustainable outcomes across the whole lifecycle of natural and built assets.  Coming together under the single new brand is also an important step in bringing our people together to realize our passion of improving the quality of life and being recognized as the best.”

The name Arcadis – derived from Arcadia, an idyllic place in Greek mythology – was first used in 1997 following the merger of Heidemij and Geraghty & Miller in 1993.  It bought EC Harris in 2011 and Hyder Consulting 2014.
