Determining the effective factors leading to incidence of human error accidents in industrial parks construction projects : results of a fuzzy Delphi survey

Abstract

The implementation of construction projects is always associated with several incidents for various reasons. Previous research studies advocated that human errors are one of the main causes of accidents in these projects. This paper aims to determine the effective factors leading to the occurrence of accidents caused by human errors in Industrial Parks Construction Projects (IPCPs) based in Iran. For this purpose, four rounds of the fuzzy Delphi survey were conducted with the presence of fifteen experienced experts engaged in the HSEE (health, safety, environment and energy) department of Industrial Parks in Iran. The reliability and validity of the questionnaire were reviewed and confirmed. Based on the results of the Delphi survey, forty-one factors contributing to human errors in the implementation of IPCPs were determined and classified into nine main groups. The survey findings manifested that the identified effective factors have a strong effect on the occurrence of construction accidents caused by human errors. The results of this research study have provided various major project stakeholders and safety managers with a useful decision-aid tool to make more pragmatic decisions in managing, reducing and avoiding the occurrence of construction site accidents particularly caused by human errors associated with IPCPs.
