  • Green growth is summarized as the national growth strategies to enhance the quality of life as a whole by converting not only the lifestyle but the economic and industrial structures into the low carbon and eco-friendly environments with the green growth industries with low carbon as the momentum for new growth, based on green technologies including renewable energy technologies, energy and resource efficient technologies, converging technologies related to technologies to reduce the environmental pollution. Roles of the construction industry along with other industries are very important in securing justifications for the cooperation between our government and industries for challenges to this green growth as well. The national effects of economy are very large from leading the construction industry to the green construction from the national level. Accordingly, this study suggested responsive plans for both government and companies for the activation of green construction by selecting 15 frontier green construction products and analyzing them by the type of strategy in Korea, as well as analyzing recent trends of overseas green construction.

  • During the last few decades, several companies and research laboratories have developed construction robots in an effort to improve productivity, quality, and reduce construction time and safety concerns. Recently, domestic construction industry is also interested in developing the construction robots. However, the studies on the research and development process is impossible in real field. A existing research's object is the development of the research on the assumption that construction's environment is a fixed form, But real construction's environment is very dynamic and atypical. So it is very difficult that we apply construction automation and robots. In order to solve this problem, this study deduce influential factors on decision making of frame construction scheduling for automated construction.

  • This study aims to review the use of graph databases in construction research. Based on the diagnosis of the current research status, a future research direction is proposed. The use of graph databases in construction research has been increasing because of the efficiency in expressing complex relations between entities in construction big data. However, no study has been conducted to review systematically the status quo of graph databases. This study analyzes 42 papers in total that deployed a graph model and graph database in construction research, both quantitatively and qualitatively. A keyword analysis, topic modeling, and qualitative content analysis were conducted. The review identified the research topics, types of data sources that compose a graph, and the graph database application methods and algorithms. Although the current research is still in a nascent stage, the graph database research has great potential to develop into an advanced stage, fused with artificial intelligence (AI) in the future, based on the active usage trends this study revealed.

  • 건설R&D 사업은 1994년에 12억원으로 시작하여 2007년에는 1,648억원을 투자하였다. 그동안 연구개발자는 연구성과 실적을 한국건설교통기술평가원에 제출하였고, 이를 기반으로 건설R&D성과 관리가 이루어져 왔다. 건설R&D사업 성과실적이 연구자의 주관적인 분석결과와 보고자료에 의존함으로써 건설R&D 성과의 객관성 및 신뢰성 확보가 어려웠다. 따라서 본 연구는 건설R&D 성과 중 개발기술의 현장적용 비용절감액 분석과 객관적이고 신뢰성있는 경제적 파급효과를 분석하고, 건설R&D의 현장적용 활성화 방안을 마련하였다.

  • 공사감리문서는 프로젝트의 수행과정을 제3의 독립적인 위치에서 모니터링한 종합적인 점검의견이라는 주요한 비정형 정보를 제공할 수 있다. 이와 같은 비정형 정보는 최근 분석방법론의 고도화에 따라 다양한 시사점을 제공할 수 있는 유의미한 자료로 평가받고 있다. 이에 본 연구는 건축공사의 최종 감리보고서 내 비정형 데이터를 대상으로 다양한 방법론을 활용하여 비용성과를 평가할 수 있는 프레임워크를 제시하였다. 세부적으로는 텍스트마이닝과 사회연결망분석을 통해 감리보고서 내 주요 키워드들을 도출하고, 해당 데이터들을 이항 로지스틱 회귀분석을 통해 분석하여 비용성과를 평가하였다. 그 결과, 감리보고서 내 비정형 데이터를 이용하여 추정된 비용성과 예측 정확도는 약 73% 수준으로 높게 도출되었다. 본 연구의 결과는 향후 건설산업에서 발생되는 다양한 비정형 데이터의 분석을 위한 기초자료로 활용이 가능할 것으로 예상된다.

  • Cost overruns, schedule delays, and a shortage of skilled labor are common problems the construction industry is currently experiencing. Modularization and standardization strategies have the potential to resolve the various problems mentioned above and have been applied for various construction applications for a long time. However, the level of modularization remains low, and modular construction projects have not been getting the full benefits. Thus, this review investigated the cutting-edge technologies currently being utilized to develop the modular construction field. For this paper, qualified research papers were identified using predetermined keywords from previous related research papers. Identified literature was then filtered and analyzed. According to the included reviews, several technologies are being developed for modular construction. For example, automated design and monitoring systems for modularization were developed. In addition, research labs are utilizing robotic arms for modular construction to achieve a high level of completion in the construction industry, as is seen in the manufacturing industry. Despite these efforts, more research and development are necessary because some automation technologies still require manual activities. Thus, there is great potential for further development of modularization techniques, and further research is recommended to achieve high levels of modularization.

  • In 2006, Korean Government decided to relocate the several Government bodies and public institutes. They include total of 49 central Government agencies, semi-government agencies, and 17 national research institutes. The completion of the relocation program has been set to be final in 2030. The target population for the city plan is set to be 500,000. The goal of MAC is first to complete the first phase of the program by 2014 within the budget. In order to achieve the goal, considerable time has been spent to properly establish the program management system. The success of MAC's Multi-function Program Administration System is too early to determine as it is still in progressive. The success depends on the operations not the development.

  • This study aims to review the research trends of landscape construction and materials, and to discover the research characteristics in Korea. The research scope was limited to the 905 articles lin the Journal of Korean Institute of Landscape Architecture between 1973 and 2003. The results of the research were as follows. The number of articles concerning landscape materials and construction were few(5.8%), compared to other research fields. The articles were categorized by sequences of the structures, the construction and management, the development of engineering and the development of materials. The articles concerning construction and construction management were categorized into 3 types of quality management; construction and materials, the cost estimation and the work classification and processes. The soils was studied together with plants suited to such soil characteristics as layer, structure, and composition.
