Platform on civil engineering, underground infrastructure, energy, construction equipment & construction machinery
For 125 years, Gebr. De Koning has been working on the border of land and water. What began as a brushwood trade has grown into a civil contractor that combines guts, craftsmanship and cooperation with broad technical strength. Awarded the designation Royal in 2025, the family business confirms its role as a reliable partner in the Dutch GWW sector.
Projects increasingly require an integrated approach: from design to execution and management. Gebr. De Koning distinguishes itself by having these disciplines in-house. With its own engineering office (De Koning Constructies), modern machinery and specialists in concrete, foundations, hydraulic engineering and earth-retaining structures, the company can respond quickly and provide customized solutions. “The beauty of our approach is that we have all disciplines in-house,” says general manager Dirk Jan Teeuw. “From design to execution and management - that integrality gives clients certainty about quality and planning.”
The challenges in the sector are great: reducing emissions, building in inner cities and future-proofing infrastructure. For Gebr. De Koning, these are opportunities to work in an innovative way. For example, projects are increasingly being carried out with zero emissions, using electric equipment and vibration-free techniques that spare the environment. In historic city centers, the company applies innovative methods, often in partnerships, protecting monuments and minimizing inconvenience to residents and businesses. Gebr. De Koning also demonstrates in large-scale infrastructure works for (semi)public authorities that planning, coordination and reliability can go hand in hand with quality and safety.
These examples are just some of the versatility within the company. From design and construction to management and maintenance, Gebr. De Koning combines knowledge, equipment and experience to provide appropriate solutions every time. “Innovation has been in our DNA for generations,” says Teeuw. “In doing so, we regularly deploy equipment and working methods that have not previously been used in the Netherlands, or that we have developed together with partners.”
A characteristic feature of Gebr. De Koning is the way it works together, both within its own teams and with clients and partners. This open and transparent attitude has led to long-term relationships with governments, municipalities and contractors. The designation Royal, awarded in the anniversary year, is the crowning glory of more than a century of courage, innovation and cooperation. It underlines that Gebr. De Koning is ready to continue building on the border of land and water in the future - reliable, sustainable and innovative.
