About us

We are an independent company without external shareholders, enabling us to set our own course aligned with our values and in the best interests of clients, colleagues and communities. Founded in 1881, we were honoured with the title of Royal company by the Royal House of the Netherlands in 1981.

Our mission is to deliver value with impactful, sustainable solutions for the natural and built environment, enabling clients to thrive and communities to flourish.

Our head office is in the Netherlands, and we have offices in more than 25 countries across Europe, Asia Pacific, Africa, the Middle East, and the Americas.

Delivering impact across our leading markets 

We focus on global leading markets where we are recognised as world‑class professionals and where our expertise delivers the greatest value for clients and society. 

Across aviation, climate resilience, data centres, energy, industry, maritime, mobility, tunnels and bridges, and water technology, we support clients from strategy through to delivery. Our integrated approach helps address challenges such as climate change, digitalisation, the energy transition and infrastructure renewal. 

The Netherlands is a core part of our portfolio. Here, we focus on buildings, rail and hubs, and the physical living environment, supporting national transitions in climate, energy, housing, resources and rural areas. 

By combining sector expertise, innovation and data driven insight, we help clients improve performance, strengthen resilience and create long term value, while enhancing society now and for the future.
