Research on Major Trends of Smart Technologies in the Construction Sector Analyzed Through Big Data: Focusing on Government-led Initiatives

In this paper, we analyzed new smart construction technologies based on the data registered from 2020 to July 2024 and identified a total of 21 technologies certified as smart construction technologies, which accounted for 21.6% of the total 167 new construction technologies. In addition, we analyzed the distribution by field and confirmed that 17 smart construction technologies (13.5%) were included in the civil engineering technology field, 3 in the architectural technology field (2.4%), and 3 in the mechanical equipment technology field (2.4%). After selecting 12 major keywords of smart construction technologies for TF-IDF analysis, we analyzed whether these keywords were included in the designated technical documents and found that the most frequently mentioned keyword among the 21 certified smart construction technologies was "data & artificial intelligence." This study is useful for understanding the current status of smart construction technologies and the utilization of important keywords in the construction technology field. Through this, it can be used as data to suggest the development direction of smart construction technologies and evaluate the technology demand and applicability in specific fields.
