Grontmij is structured along three business lines. These are: Planning & Design, Transportation & Mobility and Water & Energy. Each business line is led by a Group Director who is responsible for strategic development of these business lines on an international scale and for a region.
The Executive Board is responsible for policy, strategy, acquisitions, investments, risk management, finance and the Group’s internal coordination. Services that are best tackled centrally for reasons of efficiency or because they require a large degree of specialisation or funding are provided at Group level.
Strong management and local knowledge is crucial to our business objectives. To further develop the company it is crucial that we share the skills and expertise that exist across Grontmij for the benefit of our customers. The business line structure will enable this and ensure that areas of innovation that are of benefit to multiple markets are capitalised and the benfits maximised.
