International strategy

We conduct a selective policy on the geographical areas that we serve. We have been active for about 30 years in the Caribbean and in Indonesia, Witteveen+Bos maintains an office in Jakarta. We additionally have offices in Aktau, Atyrau and Almaty (Kazakhstan), Riga (Latvia), St. Petersburg (Russia) and in Ho Chi Minh City (Vietnam). Since 1990 there has been a great demand in central and eastern Europe for the kind of engineering expertise and know-how that we provide. Over the past two decades we have been involved in projects in numerous central and eastern European countries. In 2009 we opened our Belgian office in Antwerp, in 2014 we added an offices in Singapore and Dubai to the list, and in 2015 an office in the United Kingdom was established. Also in 2015, the Belgian consultancy MAVA joined the ranks of Witteveen+Bos.


Together with engineering firms NIRAS (Denmark), Artelia and Tyréns (Sweden), Witteveen+Bos is a member of the Strategic European Expertise Network (SEEN). These independent firms rank are among the top in their respective countries – not in size, but in quality and in service. We exchange knowledge with each other via knowledge clusters in which we discuss interesting engineering developments and make them available for the members’ domestic markets. The firms also jointly develop new products and services and cooperate with each other in various projects in Eastern Europe, Africa and China.
