Who we are

Our mission

Witteveen+Bos provides advice and designs in the fields of water, infrastructure, the environment, and construction. We exploit our first-rate expertise to solve complex issues while remaining an engaged partner to our clients. We value our independence and a corporate culture that allows every employee to reach their maximum potential, utilise their talents to the fullest, and provide the most possible value to our clients.

Knowledge multiplies in collaboration

Witteveen+Bos employees are driven to make the world a better place, with each employing their own particular specialisation. Our global network brings together talented people who share their knowledge and collaborate while – very importantly – enjoying what they do.

'At its core, our work is about knowledge: bringing the right knowledge together to solve challenging problems in water, infrastructure, the environment and construction. A strong knowledge base begins with a genuine love of the profession.'

Stephan van der Biezen, Wouter Bijman and Eveline Buter
Board of Directors of Witteveen+Bos N.V.

In practice, our knowledge only truly comes to life in collaboration with others. Knowledge multiplies in collaboration with our clients, partners and colleagues – that is when truly ingenious solutions are born.

A team of teams

The almost 5,000 projects we work on each year, utilising a wide range of backgrounds and areas of expertise, are becoming increasingly larger and more complex. This demands an integrated and multidisciplinary approach. 

Our international product-market combinations (PMC model) mean that we are a large team made up of smaller teams. This manner of organisation stimulates collaboration and entrepreneurship among our specialists, but also among clients, administrators and other stakeholders, while also ensuring maximum efficiency. 

Core qualities

This system of organisation makes demands on our way of working, which is why we are guided by three core qualities – expert, reliable and engaged – that we consistently strive to uphold. 


Being an expert begins with a genuine love of the profession – with wanting to know everything there is to know about the field. It also means continuous learning and innovation. This is how we manage to remain a top-class firm.


We see every project as a vote of confidence in the added value we provide, with each of our clients representing an element of society. We strive, therefore, for sustainable collaborations. These can only be achieved through mutual trust, with reliability being the key.


Our high level of engagement means that we look beyond the assignment we are given. We are enterprising in the solutions we devise and have an eye for the bigger picture. We engage with the tasks faced by society and our clients, and we engage with each other as colleagues.
