In 2002 COWI acquired Kampsax and Interconsult, two major Scandinavian consulting companies. These acquisitions doubled the number of staff, making COWI a leading consulting company in northern Europe and parts of Central and Eastern Europe.
COWI consolidated this position by acquiring Swedish company Flygfältsbyrån in 2009 – COWI's biggest ever acquisition – and leading UK tunnel and underground engineering consultants Donaldson Associates Ltd in 2014.
Since the Millennium, COWI has engineered a long suite of large-scale projects, including the Tanzam Highway in Tanzania (2005), the London Array (2009) and the Doha Metro in Qatar (2013). Every year, we are involved in more than 14,000 projects across the globe.
COWI is part of the world’s elite in a number of selected specialist areas, with excellent competencies in engineering, economics and environmental science. In 2017, Engineering News-Record ranked COWI 1st in solid waste, 3rd in bridge consultancy and 4th in harbour and marine structures.
