The world’s longest 3D-printed concrete pedestrian and cyclist bridge, co-commissioned by Rijkswaterstaat (the Dutch Directorate-General for Public Works and Water Management), is to be placed in Dukenburg in the city of Nijmegen, Netherlands. It will soon roll out of the printer in Eindhoven, where the 3D-printing facility of BAM and Weber Beamix is located. Today the printing process has started, but a lot has happened in order to reach this point. A lot has to be done differently compared to regular project, for instance calculating the structural safety. Witteveen+Bos was reponsible for the structural analysis, and commissioned Summum Engineering to build a parametric model, in order to elaborate and rationalize the freeform geometry, designed by Michiel van der Kley. Read more in the press release of Rijkswaterstaat (in Dutch), and our project page.
