Rotterdam, South Holland, Netherlands
I'm a structural designer and engineer familiar with and experienced in: lightweight structures such as shells, cable-nets and tents; innovative and complex geometries for buildings and bridges; as well as parametric design and computational optimization. I've been working on matching the supply and demand of buildings made from reclaimed, circular construction materials. I'm very interested in sustainability, self-sufficiency of buildings and material efficient design, and have been engaged in 3D printed materials (including concrete, recycled plastics and earth), as well as natural or biobased materials (such as timber, bamboo and strawbales). Honored to have been named 2024's Structural Engineer of the Year in the Netherlands. Our office won the Dutch National Timber Award for best building in 2024. ------------------- Ik ben constructief ontwerper en constructeur, bekend met en betrokken bij: lichte draagconstructies zoals schalen, kabelnetten en tenten; innovatieve en complexe vormgeving voor gebouwen en bruggen; en parametrisch ontwerp en computeroptimalisatie. Ik werk aan het koppelen van vraag en aanbod in gebouwconstructies gemaakt van hergebruikte, circulaire bouwmaterialen. Ik ben zeer geinteresseerd in duurzaamheid, zelf-voorzienendheid van gebouwen en materiaal-efficient ontwerpen, en heb gewerkt aan zowel 3D geprinte materialen (inclusief beton, gerecycled plastic en aarde) als natuurlijke en biobased materialen (zoals hout, bamboe en strobalen).
Summum Engineering Cooperative U.A. is a worker-owned cooperative and social enterprise. Its members are both employee and owner. As founding member, I took up the position as first CEO and chairman of the board.
Summum Engineering is a structural design, engineering and optimization consultancy, based in Rotterdam, the Netherlands. It operates in the domains of architecture, engineering and construction as well as industrial design and art. Summum specializes in the parametric modelling, finite element modelling, structural engineering and computational optimization of lightweight structures, complex geometries and sustainable buildings. Summum was recently founded on the conviction that, through continued exchange and progress in science and technology, the built environment can serve people, their well-being as well as our planet. Towards this end, Summum is pro-active in seeking a clientele and portfolio in support of a shared vision for a sustainable and durable built environment.
