Study of the causal factors of construction projects vulnerability to accidents

Statistical data in several countries shows that workplace accidents in construction industry are very high compared to other industries. Building construction projects are sites that are vulnerable to workplace accidents so that efforts to prevent accidents sets to a top priority. To recommend an effective accidents prevention strategy, comprehensive knowledge of the factors causing work accidents is needed in construction projects. The objectives of the study are: (i) identify the vulnerability factors of the construction project to work accidents; and (ii) further analyze the level of vulnerability of the factors causing the vulnerability of construction projects to accidents in construction projects. This research is a comprehensive study through the study of work accident reports in construction projects from PT Jamsostek as well as perceptual surveys through questionnaires distributed to workers from construction projects using the sampling method. The results of the study indicate that the factors causing the vulnerability of construction projects to workplace accidents are determined by 5 main factors which are: I) human factor, ii) equipment factor, iii) organizational factor, iv) management factor and v) environmental factor. The results of the analysis further explains that environmental factors are the highest factor followed by equipment factors and organizational factors, human factors and management factors. The dominant sub-factor causing the vulnerability of construction projects is " Unsafe workplace conditions " is the highest sub-factor (DoV = 8.3827), followed by a sub-factor "Equipment specifications not compliant with safety standards" (DoV=8.3467). The next sub-factor is " Lack of organizational commitment to safety " (DoV = 8.3356), “Unsafe action from workers” (DoV = 8.3145), “Unsafe conditions of workplace” (DoV = 8.3125), Lack of worker awareness to safety (DoV value of 7.3064).
