Our history
The journey continued when, some decades later, three civil engineers Dwars, Heederik and Verhey started their firm the Vereenigde ingenieursbureaux voor bouw- en waterbouwkunde in 1917. Both companies joined forces in 2012 as Royal HaskoningDHV.
In our history, we see the roots of our work. From the independent thinking enabling clients to thrive and communities to flourish, to the deep domain knowledge that is our DNA, branching out into new market sectors. Since their foundation, both companies diversified step by step and from the 70s onwards, they started to expand their knowledge base with the acquisition of specialised consultancies, both in the Netherlands and abroad.
Our family tree
Our founders shared a passion for the profession of engineering, an indestructible belief in progress and the drive to make the world a better place. This family tree (dated 2025) shows how we have grown from a small passionate group of people to an international community of 6,000 employees focused on enhancing society together with the same perseverance and ingenuity as our founders displayed. We are still an independent, employee-owned organisation. And by growing digital competences in recent years, Royal HaskoningDHV has opened up a new world of virtual engineering, enabling completely new services and business models.
