Although automation has been actively and successfully used in different industries since the 1970s, its application to the construction industry is still rare or not fully exploited. In order to help provide the construction industry with an additional incentive to adopt more automation, an investigation was undertaken to assess the effects of digital fabrication (dfab) on productivity by analyzing the cost and time required for the construction of a robotically-fabricated complex concrete wall onsite. After defining the different tasks for the conventional and robotically fabricated concrete wall, data was collected from different sources and used in a simulation to describe the distribution of time and cost for the different construction scenarios. In the example, it was found that productivity is higher when the robotic construction method is used for complex walls, indicating that it is possible to obtain significant economic benefit from the use of additive dfab to construct complex structures. Further research is required to assess the social impacts of using dfab.

The counterpart of Industry 4.0 in the AEC/FM industry is known as Construction 4.0. Its essence is the digitalization and automation of the AEC/FM industry. As robots and other technologies make their way into the different phases of the lifecycle of construction projects, the concern about the future of jobs and wages will increase. While the use of robotics has the potential to improve productivity and safety, it should not necessarily reduce total employment in the construction sector in the long run. It is expected that existing roles will evolve, and new roles will be created (e.g., in addition to designers there would be a need for employees with digital skills). Focusing on the construction phase of a robotically built concrete wall, the different roles were evaluated. From this study, it was found that there will be a time in which conventional construction and robotic technologies will coexist, leading to a higher job variability and new roles, both at the managerial and operations/execution levels. Although this study is not meant to be an exact representation of how the AEC/FM roles will change as a consequence of Construction 4.0, it opens the debate and research in this area.
