Analysis Factor Associated of Work Related Accidents in Highrise Building Project Using Fault Tree Analysis (FTA)

Abstract

During 4 years periode from 2011 to 2014 work-related accidents always increased. In 2014 there were 105,383 work-related accidents. The work accident data is dominated by the construction sector. The aim of this study was to analyze the factors associated with work related accidents in construction. This study was conducted by qualitative study design with a case study approach using Fault Tree Analysis (FTA). The population of this study were all construction workers as many as 140 people. The main informants in this study were determined by purposive sampling, workers who had experienced work accidents in May-June 2014. Data collection techniques used in-depth interviews, observation and document review. The results showed that the factors associated with work related accidents in construction were caused by human factors, environmental factors and occupational factors. Human factors that cause work accidents were working not according to procedures, perceptions of potential hazards and low safety, lack of concentration and fatigue. Environmental factors that cause work accidents are limited safety information, unsafe work environment, lack of safety signs and limited safety facilities. Occupational factors that cause work accidents include lack of supervision. Based on this research, it can be concluded that the causes of work accidents are very complex, so there needs to be coordination in project management to optimize supervision of work safety.
