Abstract

Digital fabrication has significant potential to support concrete formwork in the construction industry. While previous studies have been done on digital fabrication in construction, few empirical investigations have taken into account the cost-effectiveness of digital fabrication, which is a crucial factor. Currently, the percevied high initial cost of digital fabrication equipment makes companies reluctant to change their traditional approach. To address this knowledge gap, this study aims to determine the financial benefits of using digital technology in fabrication. Specifically, the study focuses on the use of a computer-numerical controlled (CNC) machine that can be used to automate formwork fabrication. To examine the cost-effectiveness of using a CNC machine for concrete formworks, a case study was carried out based on the prefabrication of edge formwork for a 26-story post-tensioned, cast-in-place structure. The study results indicate that the use of a CNC machine for formwork fabrication could help substantially improve labor productivity, fabrication quality, and worker safety, each of which led to a significant cost saving in the project. The study results provide evidence of the advantages of digital fabricatoin over the traditional approach and support project teams to make informed decisions when implementing digital fabrication.
