Our clients

Our regional approach, which is based on a wide range of disciplines within the entire project chain, differentiates us from the competition

With their questions, our clients constantly drive the development of our knowledge and experience. We enter into a partnership with our business and government clients, and provide full solutions.

The management of Grontmij has the following key values:

  • Client-oriented, reliable and flexible services
  • Continuous quality improvements
  • Integrated innovation
  • Multidisciplinary full solutions

Close to the customer
Grontmij is a network organisation with offices in every region. We work decentralised, near the client. As a result, we know the local context and the specific project conditions, and we capitalise on this advantage together with our clients.

Unlimited knowledge management
Thanks to a clever matrix organisation and a unique ICT concept, we achieve very effective collaboration and knowledge sharing across the borders of regions, countries and disciplines. Also at a European level, we actively use the exchange and the synergy between fields of expertise. As a result, we have fast access to the latest technologies.

Project work, the core of our operations
Project work is the basis of our organisation. Our employees work efficient and effective on your project, and with creativity, expertise, experience and a proper sense of organisation and communication. Our project leaders offer the clients a full insight into all organisational, financial, legal and obviously technical aspects required to realise a project.

Motivated and client-friendly staff
Teamwork, training, efficient management systems and modern infrastructure are additional conditions for a successful project. Quality, reliability and service are the core values of our services.
