Automated and robotized processes in the timber-frame prefabrication construction industry: A state of the art

Off-site prefabrication in the timber-frame construction industry is a trending topic in the search for sustainable building and affordable housing. This paper aims to present, based on a literature review, the current level of automation and robotization in the timber-frame prefabrication industry, the existing layouts for this type of production, the tools and equipment used to support the production line, and the limits and barriers to adopting these technologies. Based on the analysis of these themes, a Figure relating the degree of automation in relation to factors such as the level of machinery and technological tools involved, the business and workforce size, the level of lean and standardization, and the stage of prefabrication is presented and discussed.
