The effect of fatal occupational accidents on project cost in the construction industry

When the statistical data of the last ten years in Turkey are examined, it is seen that there is an increase in the cases of death, occupational disease and disability as a result of work accidents. Among all sectors, it is seen that the construction sector ranks first compared to other sectors in terms of the numerical multiplicity and severe consequences of occupational accidents occurring in the construction sector. In this thesis study, after the definition of the concepts related to occupational health and safety, explanations were made about the occupational accidents that occurred in our country and the occupational accidents that occurred in the construction sector. Data on occupational accidents that occurred in 2020 and 2021 at workplaces in the construction sector operating in the 41, 42 and 43 NACE codes included in the Workplace Hazard Classes List in the annex of the Workplace Hazard Classes Communiqué on Occupational Health and Safety were obtained from the Social Security Institution General Directorate of Service Delivery and examined. As a result of work accidents, the notifications made to the Social Security Institution were classified and the causes of work accidents were researched. In the study on work accident notifications, it was determined that the most fatal work accidents were the result of falling from a height. The tender file and the approximate cost of the construction of the 8 Classroom Zübeyde Hanım Kindergarten in Odunpazarı District of Eskişehir Province were examined. The cost of temporary edge protection systems in accordance with the standards used for the prevention of work accidents caused by falling from a height, which is the most important cause of fatal work accidents in the construction sector, was calculated. The effect of the temporary edge protection system cost on the approximate cost of the project was investigated.
