Quantitative Risk Evaluation by Building Type Based on Probability and Cost of Accidents

The construction industry has the highest frequency of injuries and fatal accidents compared to other industries. Therefore, an accurate evaluation of the level of risk is necessary to effectively manage accidents in the construction industry. Although risk assessments are used in the construction industry to identify and reduce risk, they are carried out qualitatively by the subjective opinion of safety managers. Therefore, this study proposed a quantitative risk assessment based on the risk levels of 17 building facilities. Moreover, this study classified the building facilities into groups of similar risk levels. This study involved five steps. The results of the study indicated that in terms of both accident probability and financial losses, the facility type with the highest risk ranking was “Residential buildings” (5.92). The risk assessment method proposed in this study can contribute toward reducing accidents by identifying the exact risk level for each facility type. Moreover, clients and contractors can utilize this study and its findings as a basis for different safety management approaches depending on the risk group level

Quantitative Analysis of the Accident Prevention Costs in Korean Construction Projects

It is essential to objectively evaluate accident prevention costs (APCs) to respond to high-accident rates in the construction industry. However, currently, no quantitative APC analysis model considers the properties of the Korean construction industry. Therefore, in this study, the APC quantification structure was derived to comprehensively evaluate the properties of Korean construction projects, such as occupational safety and health management funds, safety management expenses, and others. Subsequently, the current status of APC in Korea was analyzed based on case studies on 38 projects for which questionnaires were collected. As a result of the study, the average ratio of the APC to total construction cost of the target project was calculated to be 1.95%. In addition, an average difference exists between groups according to client types and facility types in the target project. This study developed an APC quantification model considering Korea’s safety-related laws and insurance systems. It is expected that the results of this study can be used as objective data for evaluation according to the target project type

Evaluation of Accident Risk Level Based on Construction Cost, Size and Facility Type

Compared with other industries such as manufacturing, the construction industry has a higher danger of fatalities. In Korea, the risk level in the construction industry is managed using the fatality rate per 10,000 construction workers. However, this statistic is lacking in determining the exact risk level because it does not consider the exact number of workers and fails to reflect the specific characteristics of the construction industry. In this study, the fatality rate is deduced by considering the facility type and the project size based on total cost. From the results obtained, considering the facility type, “Assembly” is seen to be the most dangerous facility type. Considering the project size based on total cost, “Less than 0.008 billion dollars” is the most dangerous construction scale. Considering both the facility type and the project size based on total cost, it was confirmed that the overall fatality rate could exceed the fatality rate respective to each facility type and project size. Using the proposed method, it is possible to determine the quantitative risk level considering specific characteristics of the construction industry
