Our philosophy of striving to achieve a sustainable relationship between man and the environment is symbolised by the interaction between the two main shapes which comprise the Grontmij logo: a semi-arc and a plane.

- The red stands for man: human requirements, creativity, passion and social values.
- The transparent section stands for integration: our skills, technologies, methods and systems to achieve a sustainable relationship between man and the environment.
- The blue plane stands for the earth and the environment, our habitat, which we need to treat with respect.
- The entire logo is slanted 15 degrees to the right and represents the dynamism of our company and the ambitions of our personnel, which are expressed in challenging targets.
