The incorporation of innovative technology systems into domestic construction practices has catalyzed an organic evolution of the industry, significantly enhancing the level of domestic construction technology and intensifying competitiveness. In particular, the on-site implementation of these groundbreaking construction technologies has proven effective in diminishing construction costs and accelerating project timelines. Nevertheless, despite a period of 33 years since the inception of this new construction technology system, both the volume of designated construction technologies and their practical application on construction sites remain static. As a consequence, this study introduces a strategic plan to dissect and overcome the barriers faced in the adoption of new construction technology across a multitude of sectors. The chief outcomes encompass the inception of a new construction technology utilization surveillance system, an assessment of distinct technologies, refinement of the post-evaluation system, and the creation of a new technology market system. This systematic enhancement is anticipated to foster the practical application of new construction technologies within the industry.

The ordering organizations of civil engineering project manage the construction site indirectly because the construction site is mostly located at a remote location and the public official also manages many sites. Since the civil engineering project has a wide working area, it is not easy to know the status of the whole project quickly by the indirect management method by report of the field practitioner. In order to solve these problems, the field management system between the ordering organization and the field office is changing from offline to online. This study suggests an advanced construction site management system that obtains site-related 3D information with the use of UAV and shares the information between the construction site in remote locations and their supervising authorities. To develop an UAV application system, the problems of field management in many actual sites were analyzed and derived necessary functions such as status reporting and online information management. The developed system was applied to actual field to verify its usability and compared the efficiency improvement with existing field management method.

Field trip education is frequently used in a primary education in Korea. However, it fails to provide specific research activities or feedback for students and lacks educational implication. We propose a mission-based field trip education using mobile phone. In this paper, we explain our design process, experiment at the zoo, and discuss the future work.

Construction industry try to use weather information because construction is much influenced by weather conditions. However, the researches, how to use the weather information in construction fields at present state, are not sufficient. Therefore, the purpose of this study is to present the methods for improving weather information application by analysis the present state in building construction fields. The results show that educations about application of weather information are poorly conducted though the construction engineers know that weather information is helpful to improve the performance and that weather information serviced is not suitable to apply their field's work. Based on the results, for improving the application of weather information, the construction engineers are structurally educated about applying weather information and the weather information system is developed to specialize the building construction projects. Additionally, construction companies have a long term plan to cultivate the experts who equally have a good knowledge and experience of weather information and construction technologies. These proposed methods help to decrease the influence of weather conditions and finally to improve the performance in building construction projects.

Due to the recent increase in various problems from underground development in urbanized areas, accurate underground facility information management is highly needed. Therefore, in this study, in order to utilize the Integration Map of Underground Goespatial Information in real time on-site, the function of comparing the mutual location of the GPR (Ground Penetration Radar) sensing data and the Integration Map of Underground Goespatial Information, and function of analyze underground facilities, and function of converting surveying data into a shape file through position correction & attribute editing in a 3D space, and the function of submitting the shape file to the Integration Map of Underground Goespatial Information mobile center was defined and developed as a program. In addition, for the on-site application test of the development program, scenarios used at the underground facility real-time survey site and GPR exploration site were derived, and four sites in Seoul were tested to confirm that the use scenario worked properly. Through this, the on-site utilization of the program developed in this study could be confirmed, and it would contribute to the confirmation of the quality of Shape-file and the "update automation" of "Integration Map of Underground Goespatial Information". In addition, it is expected that the development program will be further applied to the Underground Facility Map's Accuracy Improvement Diffusion Project' promoted by the MOLIT (Ministry of Land, Infrastructure, and Transport).
