The Netherlands

For over 75 years, we advise and help our clients in resolving today's complex challenges. Once started in Deventer, the Netherlands, we now offer innovative and reliable solutions in the fields of infrastructure, water, the environment and construction with more than 1,450 colleagues worldwide.

Sustainable solutions

In our projects, we bring together the right expertise to help solve today’s challenges - such as climate change adaptation, future-proof cities, the energy transition, flooding, large-scale infrastructure replacement, circular economies and healthy cities - in a sustainable manner. We see it as our responsibility to have the greatest possible positive impact on the well-being of people and the environment with our designs. Our unique approach to these challenges is based on our DNA of top expertise and collaboration with (local) partners in a culture of trust and entrepreneurship.


Both public- and private-sector clients call on Witteveen+Bos to help resolve the challenges they face. We provide advice to contractors, engineering and architectural firms, energy and water companies, railway and port authorities, and industry. In the public sector, we work for national governments, water boards, and provincial and local authorities. Our activities cover the entire chain, from policy-making and design to contracting and supervising construction. We aim to establish long-term relationships with our clients that enable us to meet their needs and expectations as effectively as possible while delivering maximum added value.

Key values

We consider it essential that our actions are guided by our three key quality attributes: expertise, reliability and commitment, because we believe that a commitment to excellence is key to developing sustainable solutions for today's challenges. 

Our corporate culture is characterised by trust and scope for entrepreneurship. With our (inter)national Product-Market-Combinations (PMC model), we are one large team of smaller teams, which stimulates cooperation, entrepreneurship and maximum efficiency between specialists, clients, administrators and environmental parties. 


At its core, our work is about knowledge: bringing the right knowledge together to solve challenging water, infrastructure, environmental and construction problems. A strong knowledge base starts with a genuine love of the profession. Witteveen+Bos employees are passionate professionals who immerse themselves in their environment and their profession, from geotechnical to mechanical engineering, from water management to environmental law and from circularity and energy transition to data-driven, digital solutions. 

We share our knowledge and best practices on a regular basis through courses, webinars and events.
