Unsafe behavior is one of the major causes of construction accidents. Managing the behavior of workers in real-time is difficult and requires huge manpower. In this paper, a new real-time locating framework is proposed to improve safety management by collecting and analyzing data describing the behavior of workers to identify habits that may lead to accidents. The aim of the study is to identify working habits of workers based on their location history. Location data is used to compare with that of other workers and equipment. The results indicate that the reuse of real-time location data can provide extra safety information for safety management and that the proposed system has the potential to prevent struck-by accidents and caught-in between accidents by predicting unwanted interaction between workers and equipment. This adds to current research aimed at automating construction safety to the point where the continuous monitoring, managing and protection of site workers on site is possible.

Construction fall accidents have been investigated by many researchers. Construction workers are prone to fall when elevations of the construction site is high. And falls are the most fatal accidents: it can be directly linked to the death. Construction fall accidents might be reduced by predetermining several areas which are highly probable to have fall accidents and by controlling such areas until the completion of the building construction. In this paper, a fall prevention system is suggested which can identify the areas where the focus on fall protection is perhaps most needed from the process characteristics. Main methodologies for this research are summarized as follows: 1. A data base on elements and types of falls is constructed from the data analysis of last 10 years fall accidents history. 2. Guideline is derived by identifying the highly probable areas of fall accidents with respect to the specific construction process. 3. Developed system is verified by applying the system to construction sites. 4. Finally a fall prevention system is suggested by utilizing the fall accidents data.

The aim of this paper is to identify and rank the main causes of fall accidents from scaffolding according to their relative importance as perceived by project managers and site engineers in construction projects in the Gaza Strip. A total of 50 questionnaires were distributed to project managers and site engineers, 35 questionnaires were received yielding 70% response rate. A total of 33 factors that cause fall accidents in scaffolding were identified through a literature review and consolidated by a pilot study. These factors were categorized into six groups: factors related to erection, factors related to the staff (Scaffolders), factors related to loads, factors related to the personal safety, factors related to the workers behavior, factors related to the personal competencies. The results indicated that factors related to the workers behavior are the major factors that caused fall accidents from scaffolds. The results revealed that the top ranked factors which caused falls accidents from scaffolding were: absence of personal protective equipment (PPE), missing ladders, wind loads, disguised the design code, lack of proper assembly or inspection, overhead tools and materials, climbing and neglect using ladders, lack of guardrails, missing bracing and working during fatigue. These findings would help contractors to understand the top factors that caused fall accidents so that they can take them into consideration in safety planning in order to minimize the possibility of their occurrences.

Although various research is being carried out to prevent the construction accidents, the number of victims of construction site is increasing continuously. Therefore, the purpose of this study is construction accidents prediction applying the boosting algorithm to the construction domains. Boosting algorithm was applied to construct construction accident prediction model and application of the model was examined using actual accident cases. It is possible to support safety manager to manage and prevent accidents in priority using the model.

본 연구의 목적은 국토교통부로부터 위탁받아 한국시설안전공단에서 운영하고 있는 건설사고조사위원회 사무국에서 '15년부터 축적한 총 90건의 건설현장사고를 대상으로 공종별 위험요소 및 재발방지대책을 key word 행태로 발굴하여 유사한 원인으로 재발되는 건설현장사고를 방지하는 자료로 활용하고자 수행하였다. 본 연구에 활용한 건설사고 모집단은 건설사고 전체를 대표하기는 어려우나 일정 규모 이상의 건설사고에 대한 분석 자료로 통계적 가치가 있는 것으로 사료되며, 향후 보다 신뢰성있는 분석을 통한 피드백을 위해서는 효과적으로 건설사고정보를 수집할 수 있는 제도개선이 필요한 것으로 판단된다. 금번 분석된 내용은 현장에서 건설안전 확보를 위한 기초자료로 활용이 가능할 것으로 생각되며, 향후 건설안전정책 방향설정의 자료로도 활용될 수 있을 것으로 기대한다.

Various safety measures have been established and implemented in order to reduce construction accidents. However, statistics data on at construction sites still show higher accident and mortality rates than other industries. As a result of investigating the causes of accidents occurring in the construction industry, most accidents resulted from the failure of the system. Therefore, the existing safety management system of the construction site is monitored so that it operates properly in the field, and it is an important factor to actively participate in construction work. In order to overcome this, the government emphasized on-site inspections and planning and implementation confirmation by public institutes to ensure the effectiveness of the safety management system through amendment of the Construction Technology Promotion Act, but the orderer' safety capability and manpower are insufficient at present. Therefore, in this study, the safety management system, such as design for safety, safety management plan, safety check, safety management cost, etc. specified in the Construction Technology Promotion Act, is regularly checked and confirmed to improve the effectiveness of the safety management system as well as to improve the safety management system of the construction site by deriving measures to strengthen the public function of the government.

Objective: The aim of this study is to reclassify human errors and to develop hands-on tools to apply the new classification for preventing human error accidents in highway construction site. Background: The main cause of accidents in highway construction was reported as the carelessness of workers. However, such diagnosis could not help us operationally prevent accidents in real workplace. Method: The accidents in highway construction were reanalyzed and the causes of human error were reclassified in order to educate and improve the awareness of human error in highway construction. Field survey and interview with safety managers and workers were conducted to find the causal relationship between the actual accidents and the human errors. Results: The most frequently observed human errors in highway construction were classified into six categories such as mis-perception, distraction, memory fail, slip, cognition error and mis-judgment. In order to provide hands-on tools to increase the awareness of human error in construction field, the human error checklist and card sorting diary were developed. Especially, the card sorting diary was designed to increase the ability in human error inspection of safety manager at construction site. Moreover, posters were developed based on actual accident cases. Conclusion: We suggested that the improved awareness and analytical report on checklist, card sorting diary and posters for construction field could collectively prevent the accident. Application: The classification of human error, hands-on tools and posters can be directly applicable on highway construction site. This analytical and collective approach preventing human error-related accident could be extended to other construction workplaces.

Many of the falling which is the number one risk factor in lethal accidents in construction could have been prevented if the right activity or supervising had been taken in time. All other measures do not preventive the fall, but rather intercept the fallen itself or preventive severe injury. The most common and the bets measures on the preventive measures are guardrails which are to be worn on the site. Workers always exposed the risk of serious accidents induced by causal effects related with environments around construction sites. In order to represent how to decrease the risk of workers, this study was accomplished with a number of interview with experienced site director, cheief of instructors, workers. And the questionaire survey (2012. 5~2012. 10) were used to make proposed policies which are expected to reduce critical disastrous accidents and strength authorized limits of director's management automatically.
