Tracking the Research on Ten Emerging Digital Technologies in the AECO Industry

Application of emerging digital technology (DT) is an attractive subject of research and is indispensable to the current goal of intelligent construction in many countries. Relevant studies have either focused on the status of a specific DT or proposed preliminary/qualitative comparisons among DTs. This paper provides a systematic understanding of research on applying DTs to the architecture, engineering, construction, and operation (AECO) industry using a mixed-review method. Ten emerging DTs are determined, and publications related to them in 2011-2020 are collected from the Scopus database. The overall status and comparisons of research on 10 emerging DTs by region, journal, and popularity are then presented. The content of research on them is examined through in-depth literature analysis (including research scenario, project stage, and literature evolution in a discipline) and theme classification. Future research directions including technology knowledge, development, application and management, and some practical implications for the country, industry, project, and enterprise, are finally proposed. This research will be informative for academics with regard to the emerging DT's opportunities in this discipline and provide support for work on the digitization of the AECO industry.
