Abstract
Digital fabrication (dfab) is establishing itself as a potential solution for the stagnating or declining productivity in the construction industry compared to other industries. However, industry’s will for adaption is still low. Thus research is needed to understand how traditional construction can be changed and improved. This thesis aims to investigate the effects of dfab on productivity, the impact to the current roles and collaboration schemes in Switzerland, and the information required through the different project phases, examining the NEST dfab unit as an example. In a first part, a procedure for comparison based on productivity and CYCLONE simulation technique was proposed and successfully applied to an on-site mesh mould wall case study, comparing traditional construction with dfab. The results of the assessment demonstrate that the productivity is higher for complex structures, showing that dfab can be worth adapting also from a cost perspective. In a second part, the industry and social impact of dfab is examined. Key elements and problems of dfab are investigated when trying to apply them to existing delivery systems in a transition process. Possible solutions, including integrated project delivery, building information modelling and new roles, are shown to enable dfab along the construction value chain, summarized in a proposed future construction process. Overall, this thesis provides insights in dfab based on experiences from the NEST project, showing that dfab could be sustainable in various aspects. Show more
