Proceedings of the Design Modelling Symposium Berlin 2022, Towards Radical Regeneration
Facing the challenges of our environmental crisis, the AEC sector must significantly lower its carbon footprint and use of first-use resources. A specific target is the reduction of the amount of concrete used. Funicular structures that base their strength on their structurally-informed geometry allow for material efficiency. However, a bottleneck...
p>This paper presents the design, engineering and digital fabrication strategies for a circular pedestrian bridge to be built as part of “De Groene Boog” development of the A16 highway north of Rotterdam, The Netherlands. The bridge is designed as a lightweight funicular unreinforced concrete gridshell with openings based on the principle of a thre...
Conventional construction of doubly-curved concrete structures is a time-, labour- and cost-intensive process. Flexible formworks have already been identified as a possible solution to produce such structures more efficiently. The KnitCrete technology developed at ETH Zurich uses 3D weft-knitted fabrics as stay-in-place formwork, which deliver mult...
This paper describes the structural design, digital fabrication and construction of KnitCandela, a free-form, concrete waffle shell with KnitCrete, a falsework-less formwork approach using a custom prefabricated knitted textile as multi-functional, structural shuttering layer and a form-found cable net as the main load-bearing formwork. The digital...
Knitting offers the possibility of creating 3D geometries, including non-developable surfaces, within a single piece of fabric without the necessity of tailoring or stitching. To create a CNC-knitted fabric, a knitting pattern is needed in the form of 2D line-by-line instructions. Currently, these knitting patterns are designed directly in 2D based...
A novel formwork system is presented as a material saving, labour reducing and cost-effective solution for the casting of bespoke doubly curved concrete geometries. The approach uses a custom knit technical textile as a lightweight stay-in-place formwork with integrated solutions for the insertion of additional elements, and is fabricated as a near...
This paper describes the development of an unreinforced, freeform vault consisting of 399 discrete limestone blocks with thicknesses ranging from 5 to 12 cm. The vault covers an area of 75 m2 and spans more than 15 m in pure compression, without mortar between the blocks. We discuss how the design of the vault and its individual pieces was entirely...

Digital fabrication technologies typically encounter difficulties in satisfying the demands of structural integrity requirements prescribed by building codes and expected by society for large scale applications. This is highly detrimental for novel technologies competing with established conventional building processes. This project analyses structural integrity requirements in dfab technologies within the National Centre for Competence in Research (NCCR) Digital Fabrication with the objective of opening the way for large scale, mass market applications.
This research, part of the NCCR Digital Fabrication, focuses on developing a formwork system for complex, bespoke geometries needing custom formwork with integrated solutions for reinforcement. Creating a fabric stay-in-place formwork combines flexibility of moulding with structural properties. The formwork system is based on a prefabricated textile, transported with minimised volume, tensioned on site. It has accurate placement of material, incorporates reinforcement and acts as stay-in-place formwork. The prefabricated fabric formwork is created by combining knitting and weaving techniques for technical textiles made out of fibres such as alkali resistant glass fibre, carbon fibre, etc.
