Who we are

FDN (Functional Design Netherlands) is an innovative engineering & construction group located in The Netherlands. FDN was founded in 1996 for the development of innovative Civil Technologies. FDN has developed and applied many innovative technologies internationally, provided civil engineering consultancy services, and is specialised in sustainable and durable projects. Examples are the floating constructions such as harbours, seaports, marinas and breakwaters and Ultra High Performance Concrete bridges and structures.



The first Ultrabridge was successfully built in Rotterdam in 2012. Since that time, the bridge has won the well-recognised Dutch Concrete Award 2013 and the FiB Special Mention Prize for Outstanding Concrete Structures. The unique characteristics and appearance of the bridge have brought Ultrabridges to a leading position in the current market of sustainable bridges.


Ultrabridge Description


​FDN Ultrabridges are unique durable traffic bridges, which are based on an effective modular building system so that bridges up to 100m in length can be built economically with only two standard elements.


Design Your Own Railing


The general concept of Ultrabridges enables to design any shape of railing from different materials such as UHPFRC or steel. The railing from high-strength concrete is slender and very durable. Different colors of railings can be reached by adding pigments.
