A Study of Improvement on Accident Rate Index of Construction Industry

Abstract

: Since the introduction of the converted accident rate in Pre-Qualification(PQ) process in 1992, the safety evaluation system has contributed to a reduction of construction accidents and development of the safety management system in public construction projects. As the comprehensive evaluation method the government plans to introduce includes the indicators ‘accident rate’ and ‘death rate per 10,000 workers’, the influences on the safety evaluation in the bidding process would be broader in public sector construction projects. However, the current safety evaluation system is operated by different estimating standards in the bidding process. At this point, a study of improvement on the safety evaluation index is required to review its current conditions and to propose its efficient operating method. Therefore, the purpose of this study is to analyze problems of the current safety evaluation system through the questionnaire survey on the qualified workers in construction safety management and to propose an improvement plan for the problems noticed. Our results suggest the standards of the unified process for the safety evaluation index, the size of construction firms needed for accident rate estimation, and the improvement plan for unreported accidents. The proposed improvement plan enables the reasonable estimation and efficient operation of the safety evaluation index, and further, it would contribute to reducing construction accidents through the activation of voluntary safety management by construction firms. costs of construction companies. To solve the problems, this study suggests the reduction of the reflection range and enhances prevention activities and punishment about concealment. Lee This study verified the effect of the converted accident ratio on the contract of construction work. Case analysis results, the converted accident ratio scarcely has an effect on evaluation results of PQ. Ahn et al. (2005) In order to prevent contractors ’ shrinking injury reports of the accident rate survey, this study suggested the ways of improvement of injury ratio assessment regulations through the questionnaire survey on the managers of general contractors. In order to get improvements related to the ratio of the accident, this report provided solutions; strengthen observation systems, heavier punishment of concealment, and bigger range of the exception of the accident rate from minor accidents.
