The purpose of this study is to establish a novel system for on-site management of construction and demolition waste. Construction waste has always been one of largest waste in the world and has long lacked an effective management system. Although various countries have planned the disposal of waste at the political level, the real-time and effective management of construction sites has not been mentioned. Especially in China, the continuous development of the construction industry also generates a large amount of waste, and China is not prepared for a large amount of construction waste. In order to alleviate the huge impact of construction waste on society and the environment, this study proposes a waste management method that combines Building Information Modeling technology and Radio Frequency Identification technology. Through this research, by using information technology to manage the generation and discharge of construction waste, and record the amount and information of waste generation, also improve the management method of construction waste.

Typical highway infrastructure systems include roadway pavement, drainage systems, tunneling, and other hardware components such as guardrails, traffic signs, and lighting. Tunnels in a highway system have provided significant advantages to overcoming various natural challenges including crossing underneath bodies of water or through mountainous areas. While only a few tunnel failure cases have been reported, the failure rate is likely to increase as these assets age and because agencies have not emphasized tunneling asset management. A tunnel system undergoes a deterioration life cycle pattern that is similar to other infrastructure systems. There are very few agencies in the United States implementing comprehensive tunnel asset management programs. While current tunnel asset management programs focus on inspection, maintenance, and operation safety, there is an increasing need for the development of a comprehensive life cycle tunnel asset management program. This paper describes a conceptual framework for a comprehensive tunnel asset management program. The framework consists of three basic phases including a strategic plan, a tactical plan, and an operational plan to provide better information to the decision makers. The strategic plan is a basic long term approach of tunnel asset management. The tactical plan determines specific objectives and the operational plan actually applies asset management objectives in practice. The information includes operational condition, structural condition, efficiency of the system, emergency response, and life cycle cost analysis for tunnel capital improvement project planning.

국내 건설신기술제도는 건설업계의 자발적인 기술개발을 유도하여 국내 건설기술 수준 향상 및 경쟁력 강화에 기여하였다. 특히 건설신기술의 현장적용으로 공사비 절감 및 공기단축의 성과를 달성하였다. 그러나 건설신기술제도가 도입된 지 33년이 지났지만, 건설신기술의 매년 지정건수와 건설현장 활용실적은 정체 수준이다. 따라서 본 연구는 건설신기술의 현장활용 저해요인을 다각적으로 분석하고, 현장활용 활성화 방안을 제안하였다. 주요 결과는 건설신기술 활용실적 모니터링 제도 도입, 특정공법심의 기술위주의 평가, 건설신기술 사후평가시스템 개선, 건설신기술의 기술마켓시스템 등록체계 구축, 건설신기술의 활용실적 관리방안을 제안하였다. 이러한 제도개선은 건설신기술의 현장활용을 촉진할 것으로 기대된다.

New technologies using a CNC machine to reduce the production cost of free-form buildings are being developed. To produce free-form members with such technologies, a vast free form building should be first divided into multiple panels that can be produced. Considering the curved surface of free-form buildings, the shape and size of divided freeform panels vary, which will lead to a great deal of errors. Currently, the engineers and designers complete the panelizing work through trials and errors even in large-scale projects, which results in increased construction duration and cost. Thus, it is necessary to develop a freeform panelizing technology to maximize the economic effects of free-form concrete member production technology. The purpose of the study is to analyze influence factors on panelizing of free-form buildings, which is a preceding research for development of a panelizing technology. The influence factors drawn will provide a core basis for development of panelizing technologies for free-form buildings.

A slipring or FORJ are usually adopted in order for power supply of Geo-centrifuge and input/output data acquisition. Since using slipring causes quite a lot electrical noise, an optical communication using FORJ becomes more general for data acquisition. Such data acquisition devices, however, require frequent maintenance and replacement due to deterioration by long term usage. DICT has set up a real-time wireless date acquisition system using wireless communication technology instead of FORJ. The system enables a remote measurement at any inertial acceleration field up to 100g level and provides as same performance as FORJ. The priority of this system is to use a normal modem substituting a special FORJ.

Construction robot-based automation can contribute to productivity and quality improvement by replacing manpower in tasks that have simple repetitive properties or require high precision. In this respect, layout work is one of the most effective tasks in introducing robot-based automation technology. The development of a robotic layout system for building structures has recently been promoted in Korea, and a prototype of a marking robot has been produced. However, for commercialization, the technology improvement is required through the analysis of major improvement directions. Therefore, this study aims to derive the improvement priorities of the marking robot based on the evaluation of researchers who participated in the development process. As a result, there was a high demand for improvement in factors such as the robot's precise positioning method and robot size and weight. The results of this study are expected to serve as guidelines for the efficient input of limited resources in the future technology development process.

국내 건설산업의 지속적인 노령화 및 인력부족 문제는 노동집약적 건설업의 특성과 지속되는 청년층의 건설업계를 향한 부정적 이미지가 증가하는 현실을 감안할 때 더 이상 미래의 문제가 아니라 국내 건설업의 생존을 위해 꼭 해결해야할 선결과제임에 틀림없다. 본 연구는 국내 건설산업이 직면한 건설 인력부족의 근원적인 문제점을 조명하고 인력부족문제를 해결하기 위해 최근 5년간 패스트트랙 성향의 신속한 대응책을 마련하고 있는 영국의 MMC 사례와 약 20년간의 중장기적인 대응방안을 모색하고 있는 싱가포르의 Buildability 사례를 비교분석함으로써 양국이 제시하는 전략적 대응방안의 시사점을 도출하고 유사한 전략을 구사하기 위한 방안을 제안하였다. 그리고 본 연구가 제시한 대응전략을 프로세스 다이어그램으로 제시하여, 향후 전략개발의 방향성을 명확히 하였다.
