The Hague, 7 September 2026 — Deerns’ rise in the 2026 ENR Top 225 International Design Firms ranking reflects its ability to help clients navigate increasingly complex infrastructure challenges.
International engineering and consultancy firm Deerns has once again been recognised in Engineering News-Record’s (ENR) Top 225 International Design Firms ranking, continuing its upward trajectory since first entering the ranking in 2022.
The latest ranking, based on 2025 international revenues, reflects the continued growth of Deerns’ international business and its expanding role in markets shaped by digitalisation, energy transition and climate change.
“Our rise in the ENR ranking reflects the strength of our international business,” said Deerns’ CEO Tjerk van der Meer. “As clients face growing challenges in digital infrastructure, energy, climate resilience and sustainability, we bring the right expertise together to help them make future-ready decisions.”
The ranking comes at a time of significant transformation across the global engineering and construction sector. ENR identifies artificial intelligence, climate resilience, energy transition and increasingly complex digital infrastructure as major forces reshaping demand for design services.
For Deerns, this transformation is reflected particularly strongly in the growing demand for expertise in data centres and other mission critical and high-performance environments in electronics, life sciences, healthcare, real estate and airports.
Growth across international markets
Deerns’ upward trajectory is supported by growth across its regional markets. Ongoing revenue growth in Brazil, France, Germany, India, Italy and Spain demonstrates the company’s ability to build its international presence while responding to local market needs in the Netherlands. This growth is creating opportunities for Deerns to bring knowledge and specialist expertise across borders.
Engineering for a more complex infrastructure landscape
The latest ENR findings highlight how quickly demands on design firms are changing. AI is driving investment in digital infrastructure, while climate change is increasing demand for resilient, adaptable buildings.
Clients also expect greater sustainability, energy efficiency and whole-life performance. “We see these trends as an opportunity,” added Van der Meer. “Our role is to lead our clients in developing digital, resilient and adaptable infrastructure that delivers long-term value.”
The 2026 ENR ranking reinforces Deerns’ position as an international engineering and consultancy partner for clients developing the infrastructure needed for a rapidly changing world.
