Engineering the Ultimate Prefab Pedestrian Bridge
Standard concrete is obsolete. For a modern prefab pedestrian bridge, the industry must look toward materials that actually last. At FDN Group, we have replaced traditional heavy casting with uhpc concrete. It is a game changer. With a compressive strength exceeding 150 MPa, this material allows us to design bridges that are incredibly thin yet structurally indestructible. We achieve span-to-depth ratios of 1:60. This is significantly more efficient than the 1:35 ratio found in standard post-tensioned structures. It allows us to rival the visual lightness of prefabricated aluminum pedestrian bridges while providing a density that prevents any form of internal corrosion.
Our bridge construction service focuses on eliminating the weaknesses of steel. Steel rusts. It requires painting. It demands inspections. Our UHPC solution does none of that. By removing conventional reinforcement where possible and relying on fiber-matrix integrity, we ensure that the structure is impervious to de-icing salts. It simply lasts longer.
- Technical lifespan of 100+ years without structural degradation.
- Extreme resistance to freeze-thaw cycles and chloride diffusion.
- Maintenance costs reduced to nearly zero over the entire lifecycle.
Proven Modular Foot Bridge Performance in the Field
Theory is nothing without proof. Our projects demonstrate that a modular pedestrian bridge is the most logical choice for urban and natural environments. In Rotterdam, the Bridge Hoekersingel used only 9m³ of concrete to span 19 meters. This is an unprecedented level of material efficiency. It won awards for a reason. In Eindhoven, the Tongelbridge set another record as the world’s first bridge made of white ultra-high-performance concrete. It spans 22 meters with a deck height of only 0.4 meters. These are not just numbers. They are proof of a technology that works in real-world conditions.
Installation is where the modular foot bridge truly shines. We do not believe in months of site disruption. We believe in hours. By using our ultrabridge modular system, we can install a complete bridge deck in less than a day. In Zoetermeer, we even relocated a complete tunnel and bridge deck during the Randstadrail project in a single operation. Speed is a requirement, not a luxury.
The logistics are simple. Because our components are designed to fit within standard shipping containers, we can ship a prefabricated foot bridge anywhere in the world. Local contractors can then perform the final assembly under our guidance. This level of adaptability is why we are also leaders in large-scale harbour construction and the engineering of floating structures. We build components that fit together perfectly.
Sustainability and the Future of Prefab Bridges
Construction must stop being a burden on the planet. Through our partnership in the urbcon project, we have mastered concrete mixes that utilize 100% by-products. This is not a marginal improvement. It is a 70% reduction in CO₂ emissions compared to standard infrastructure projects. Every prefab bridges solution we deliver is part of a circular economy. The elements are modular. They can be moved. They can be repurposed. Even our floating breakwater designs follow this principle of low-impact, high-performance engineering.
Precision manufacturing in a factory environment ensures that waste is eliminated. On-site casting is messy and unpredictable. Prefabrication is exact. This control allows us to integrate smart sensors into the deck for real-time monitoring. We know exactly how the bridge performs every second of its 100-year life. This is the new standard for public infrastructure. It is durable, it is smart, and it is available today.
