Abstract
The number of fatalities in the construction industry is highest among all industries; thus, various losses in the form of fatalities in construction represent a significant factor for safety management. If a fatality occurs, it is important to estimate the overall loss, as a significant financial loss occurs for each project participant. However, in studies of the cost of accidents involving a fatality conducted abroad, the framework cannot be applied as it is because insurance types, systems, and legal cost systems differ by country. Therefore, we developed a framework for calculating the fatality loss considering various aspects of labor, industry, and regulations in Korea. This was done in four steps: (i) data collection and criteria selection; (ii) proposed framework development; (iii) conduct of questionnaire surveys for the case study; and (iv) analysis and evaluation of the case study. As a result of the data analysis after the case study of general construction companies, the total fatality loss was estimated to be 2,198,260 USD/person. The contributions of this study are the development of a framework composed of newly discovered items that can acquire reliable data in consideration of the properties of the construction industry.
Highlights
Framework optimization by applying the characteristics of the construction industry; Selecting reliable items that can be obtained from construction companies; Discovering and applying new items related to loss costs; and Developing a framework for calculating comprehensive loss costs
As a result of grouping 78 cost cases previously, as shown in Table 4, they could be classified into a total of 14 intermediate groups as follows: the income loss cost, human cost, medical cost, medical leave wage, survivor benefit, funeral cost, compensation cost, time and productivity loss, material loss, financial loss, intervention cost, penalty, fine, and administrative loss cost
These 14 intermediate groups were grouped based on the general cost management work breakdown structures of Korean construction projects. This was done because when developing survey items for a case study, this method can serve as a basis for increasing the reliability of the acquired data
Summary
The construction industry is considered to be very important to the economies of most developed and developing countries, as construction is one of the key contributors to national economic growth [1,2,3,4]. Based on a report published by Choi et al [17], our research team reviewed the fatality rate, defining it as the number of fatalities per 100,000 full-time equivalent workers by accident (as of 2017) in 35 countries for which information can be obtained among Organization for Economic Cooperation and Development (OECD) member countries. Insurance types, systems, and legal cost systems that are differentiated from other countries were defined as Korean construction characteristics Given these characteristics of the construction industry in Korea, a framework to calculate the fatality loss that considers them is necessary. This study attempts to develop a useful framework to calculate the fatality loss while taking into account the characteristics of the Korean construction industry, focusing on construction projects and using reliable information. Framework optimization by applying the characteristics of the construction industry; Selecting reliable items that can be obtained from construction companies; Discovering and applying new items related to loss costs (delay reimbursement cost, etc.); and Developing a framework for calculating comprehensive loss costs
