In recent years, construction projects have been forced to cope with lack of skilled labor and increasing hazard circumstance of human operations. A construction robotic system has been frequently accomplished as one alterative for overcoming these difficulties in increasing construction quality, enhancing productivity, and improving safety. However, while the complexity of such a system increases, there are few ways to carry out an assessment of the system. This paper introduces a knowledge-based multi-criteria decision-making process to assist decision makers in systematically evaluating an automated system for a given project and quantifying its system performance index. The model employs linguistic terms and fuzzy numbers in attempts to deal with the vagueness inherent in experts' or decision makers' subjective opinions, considering the contribution resulted from their knowledge on a decision problem. As an illustrative case, the system, called Robotic-based Construction Automation, for constructing steel erection of high-rise buildings was applied into this model. The results show the model's capacities and imply the application to other extended types of construction robotic systems.

In the present study, annoyance caused by diverse construction noises was evaluated through surveys. A survey with a total of 110 construction workers was carried out to investigate annoyance from construction noises at different construction phases. The most effective item of adverse by construction noise was annoyance and the most annoyed construction stage was destruction construction. There were high correlation between work performance and work safety as well as work safety and speech interference. Participant's noise sensitivity were significant between low and high group at work performance, work safety, speech interference.

In a domestic construction field, after floor is constructed, protector for construction surface is set up to prevent the surface of the floor being scratched and polluted. However, the problem is that contaminants discharged with the removal of the protector for construction surface exert a bad influence for the indoor air quality. In the research, it tested to the contaminant reduction performance of the adsorption protector for construction surface using powder of charcoal by the alternative proposal of such protectors for construction surface

The effectiveness of Building Information Modeling (BIM) tools and processes has been recognized by the industry and owners are beginning to adopt Triple Bottom Line accounting practices, to enhance economic performance and environmental and social performance. However, the widespread and practical application of Green BIM remains largely unrealized. The authors identify that lack of understanding of the applicability of sustainability metrics to BIM design process is a significant barrier to this adoption. Through literature review this paper outlines the various sustainability metrics available to construction and elaborates on the potential of BIM for sustainable design. The paper maps and correlates applicable concepts of sustainability evaluation systems to BIM and describes the constraints in current BIM tools.

An automatic construction system in Korea is now at the stage of the full automation like in Japan, and an actual pilot project is going to be built in 2009. However, in developing a new construction system that has never been implemented before, there is a need to assess the performance and to consider the uncertainty of the system. The program evaluation and review technique (PERT) allows dealing with this uncertainty. Thus, this paper implements an analysis of the process of steel fabrication and makes suggestions for time-related problems arising from the analysis. The time required for steel erection by the automatic system was compared with that in the traditional method. In the result, finding out another construction process and improving robot performance were proposed to resolve the problems. The results will contribute to promoting the development of an efficient system for the new automatic construction system.

In this study we examine Taiwan's overall performance in accordance with sustainable construction by developing an appraisal indicator framework. The framework consists of five layers, from bottom to top: the indicator; the indicator category; the core cluster; the theme; and the overall performance. The procedure for the development of a sustainable construction indicator system is outlined. Finally, a framework consists of 3 themes, 10 core clusters, and 33 indicator categories are established. Following the established framework, 67 proper indicators are selected for each category in the framework, and data of the 53 indicators are collected respectively from a nation's statistical databank in Taiwan. Sustainable construction index aggregated step-by-step from the indicators, the indicator categories, the core clusters and the themes is computed to assess Taiwan's progress in sustainable construction. The preliminary results and the discussion are reported.

최근 국내 건축현장에서 붕괴사고가 계속해서 발생하고 있어 시공 및 자재 품질 점검과 관리에 대한 공사감리의 중요성이 증가하고 있다. 현행 제도 및 기준에 의하면, 공사감리 업무는 주요 책임이 있는 감리자가 건축현장에서 진행되고 있는 시공 품질, 자재 품질, 재시공 이력 등이 상세하게 기술하여 공사감리보고서를 작성한다. 이러한 문서는 대표적인 비정형데이터로 건축현장에서 생성되고 있는 데이터의 80%의 비중을 차지하고 있으며, 건축현장의 품질정보가 상세하게 기록되어있다. 본 연구에 건축현장에서 발생하고 있는 공사감리보고서를 텍스트마이닝으로 전처리 후 감성사전을 구축하여 품질성과 수준을 평가하고 계량화할 수 있는 SL-QPA 모델을 제안하였다. 모델에서 산정된 성과 점수와 법적 기준에 의한 지표와의 피어슨 상관관계 분석하고, 상관계수에 대한 일원분산분석 결과는 통계적으로 유의미하였다. 제안된 SL-QPA 모델은 현행 건축현장 품질성과 진단에 상호 보완적으로 활용될 수 있고, 공사단계에서 연속적으로 생성되는 비정형데이터를 활용하여 점검 및 관리 활동의 적시성을 향상시킬 것으로 기대된다.

Bridges are exposed to very severe environment and experience, as service life increased, elevated traffic load and traffic flow, in addition to natural disasters. In comparing to other road structures, bridges may cause more significant damage, such as human-involved accidents, to the society in the event of collapse. A certain level of service shall be necessarily secured to assure the minimum safety of users. The cost for manage and preserve bridges will increase gradually and more restrictions will be loaded to efficiently distribute the limited resources, such as monetary budget and human resource etc. In order to enhance performance and serviceability of bridges with the limited resource, asset management technique has been applied into the bridge management system, which capitalizes the road infrastructures including bridges and assess them in accordance with the government finance report. In the application of asset management, there must be a tool for assess the performance of bridges and this study introduces the basic information on the definition and role of performance measures for asset management for bridges. This research suggests future development direction of performance measure for asset management for bridges in Korea.
