On the basis of the guideline "2012-104(2012.9.26.)" notified by the ministry of employment and labor, this paper provided the baseline data and the improvement proposal in applying risk assessment to a construction site by group interview & survey of construction workers. The worker's awareness and action plan of safety and health were investigated by numerical analysis. From the result of group interview and the survey of construction workers, it was found that most of construction workers feel the danger during the work. The results also shows that risk assessment can help to change & raise the awareness of safety and to reduce the industrial disaster. In addition, simple safety management activity such as TBM & active education of safety will be necessary for safe workspace and the active TBT(tool box talk) which combines TBM & the education of safety will be also effective.

Accident rate in domestic construction industry has been increased rapidly in every year. In particular, the rate of death has been shown very high compared with other industries. It means that safety activities performed by government is not effective in reducing the rate of accident. To solve these problems, the risk factors should be predicted in advance, controlled, monitored and managed from start of project to end of project. However, most studies have been conducted by using frequency of occurrence of accident and only listed the importance of risk. Therefore, the objective of this study is to provide basic material to develop risk quantifying model for human accidents on construction site in South Korea. In the future, it is expected to be used as a reference of study on developing safety mangement checklist in construction industry and model for forecasting accident.

Due to recent enhance of safety law and regulations in construction sites, safety inspectors have been more required in construction sites. However, most of them are novice for safety inspection which have not enough experience and skill. Therefore, the novice safety inspector's performance on hazard recognition needs to be improved for effective safety management. The performance of safety inspection is influenced by the inspector's experience and background because the inspection is usually conducted by the inspector's eyes. Therefore, there is a difference in safety inspection performance between novice and experienced safety managers. This study aims to analyze the gap of risk perception between novice and experienced safety managers using quantitative visual data. For this objective, this study conducted eye tracking experiments for novice and experienced group to evaluate cognitive performance of safety risk factors. The results provides the level of safety awareness based on their experience in construction safety. The limitation of this study is a lack of the number of samples used in this study and did not consider the various characteristics of the participants. If these limitations are supplemented in future research, it can be used to develop safety education contents for novice safety managers.

Risk level for each construction work can be very important factors to establish advanced preventionmeasures. But it is important how to produce it. There are three different methods to set it up for consturuction situation. They are as follows; 1) occurrence frequency = the number of accident workers of each work kind / yearly accident workers 2) occurrence frequency = the number of accident workers of each work kind / yearly workers 3) occurrence frequency = the number of accident workers of each work kind / the total workers All these three concepts(=averaged concept)are analyzed. Additionally frequency based on discrete curve, and severity based on continuous curve are also combined for producing risk level with more scientific approach. This risk level can be very useful to make prevention plan or take measures at construction sites. This is study result can change existing risk level concept to new concept of it, namely rail way work and in-water work showed be high risk level and RC work be low risk level, different from the situation which we have thought commonly, so far.

The construction of bored tunnels in soft ground inevitably causes ground movements. In the urban environment these may be of particular significance, because of their influence on buildings, other tunnels and services. The prediction of ground movements and the assessment of the potential effects on the structures is therefore an essential aspect of planning, design and construction of a tunnelling project in the urban environment. In this study, to minimize the effect of tunnelling-Induced ground movements on the adjacent structures, a system for tile settlement risk management was developed. The GIS based risk assessment system for adjacent structures developed in this study consists of several modules such as building information module, settlement evaluation module, potential risk assessment module for adjacent structures, and analysis module for monitoring data. This system focuses on controlling and managing construction processes that may lead to settlement In the surrounding buildings and can contribute to producing the optimum technical and economic design.

The live-line works are very dangerous works on direct contacts or neighboring contacts with the distribution line. But most of domestic electrical construction companies that have performed live-line works are small-scale companies. Accordingly, safety management system and manuals to insure worker's safety haven't sufficiently had. In this paper, risk and status of accidents for the live-line works were analyzed and the necessity of introducting risk assessment for live-line works was identified by a questionnaire survey of electrical construction companies and education institutions.

본 연구는 2008~2013년 한국의 은행 대출 자료를 이용하여 건설 및 부동산업으로의 대출 집중과 은행 위험의 관계를 분석하였다. 각 은행의 기업대출에서 건설, 부동산업으로의 대출이 차지하는 비중을 이용하여 건설 및 부동산업의 대출을 산정하였다. 은행 위험은 부실여신(3개월 이상 연체 및 무이자 여신) 규모와 은행의 자기자본비율로 산정하였다. 분석 결과에 따르면, 1기 이전 은행의 건설, 부동산업 등으로의 대출 비중이 증가할수록 은행의 부실여신 규모는 감소하고 자기자본비율은 제고되는 것으로 나타났다. 은행의 특정 산업으로의 대출 집중은 은행의 위험을 증가시키지 않을 것으로 추정된다. 이는 대출집중으로 인해 은행들이 해당 산업에 대한 대출 전문심사 능력향상이 향상됨에 따라 이들 산업에 대한 정보비대칭성을 낮출 수 있기 때문인 것으로 추정된다. 한국의 경우 건설 및 부동산임대업으로의 대출 증가가 은행의 부실대출 위험으로 연계될 가능성은 크지 않은 것으로 진단된다.

Current risk assessment methods typically determine accident risks embedded in construction projects by combining severity and frequency; however, they do not reflect the characteristics of construction projects. To solve the problem, this study aims to develop a novel risk assessment method that combines severity, frequency, and disaster influence factors (i.e., weather conditions and worker's characteristics) for assessing risks of activities occurring on a construction site actually. In this study, a severity was estimated by death against victims, and a frequency was estimated by the victim rate. The frequency was then converted to probability taking disaster influence factors into account. Thus, instead of considering severity and frequency for assessing the original risks (RO), the proposed method uses severity and probability to yield adjusted risks (RA) for each activity. A case study was conducted to determine if the proposed method works as intended in a real setting. The results show that RA is more sensitive to disaster influence factors than RO and, therefore, is able to assess the actual risks reflecting the working environment and conditions of a construction site. This study contributes to risk management of construction projects by offering a risk assessment method that measures a possibility of potential disasters from the probabilistic perspective. This method would help project managers assess accident risks in a more systematic and quantitative manner.

본 연구의 목적은 플랜트 건설사업에서 모듈러 설계대안에 대한 위험기반의 평가지수를 도출하는 모델을 제안하는 것이다. 이에 따라 ① 기초사업비와 모듈을 적용하는 대상과 범위를 설정하는 단계, ② 설계, 구매, 제작, 운송, 시공업무에 대한 중요도, 편리성, 효율성 지수를 평가하는 단계, ③ 중요 위험사건의 영향에 따른 경제적 손실을 예방하기 위해서 필요한 예비비를 분석하여 총사업비를 추정하는 단계, ④ 모듈 설계대안별로 평가된 관리업무의 효율성 지수와 총사업비를 비교하여 RVI를 도출하는 단계로 구성하였다. 그리고 모델의 사용성을 검증하기 위해서 Module Plan-A는 Pipe Rack을 모듈로 적용하는 경우, Module Plan-B는 Steel Structure, Pipe Rack, Process Module을 모듈로 적용하는 경우로 설정하여 관리업무의 중요도, 편리성, 효율성 지수를 평가하고 위험예비비를 포함하여 총사업비를 추정하였다. 이와 같은 과정으로 모델을 검증한 결과, 1개의 공종에 모듈을 적용한 Module Plan-A 보다 3개의 공종에 모듈을 적용한 Module Plan-B가 관리업무의 효율성은 낮은 것으로 나타났지만, 기초사업비에서 간접비가 절감되어 종합적인 RVI는 높게 평가되었다.
