One family. A focused platform.
Rönesans Infrastructure Systems (RAS) was formed by Rönesans Holding to bring its construction and infrastructure businesses together on a single, focused platform. RAS carries the group’s founding trade — construction, since 1993 — and the infrastructure investment businesses that grew from it. Inside RAS sit our construction operations in Türkiye, our European platform — Ballast Nedam in the Netherlands together with Heitkamp’s operations in Germany and Switzerland — and our international construction business, alongside four infrastructure investment verticals: social, transport, renewable energy and digital infrastructure.
An integrated platform for critical infrastructure.
RAS brings construction and infrastructure investment together, focused on sectors with strong, long-term demand. Four investment verticals — social, transport, renewable energy and digital infrastructure — stand on a shared backbone of development, financing, engineering, delivery and operation.
Across them, we develop and operate world-class PPP hospitals, critical national transport corridors, a diversified portfolio of wind, hydropower, solar and battery-storage projects, and AI-ready data centers serving the region's growing demand for cloud storage and AI workloads.
We rank among the leading contractors in Türkiye and in Europe by international volume, with roughly €40 billion of contracts completed since 1993
