Examination the Influence of Human Factors in Indian Building Construction Sites

Abstract

This research intends to explore the human factors which lead to non-fatal accidents (i.e. first aid case, near miss, lost time injury) and assessing safety supervision factors in building construction sites. A total of hundred non – fatal accident data is collected for the analysis. Human factors such as age, experience, language, education level and competency of the worker are explored using data analysis method. The root causes for the accidents are also determined and it is found that 22% of the construction site accidents are due to improper supervision. Furthermore a questionnaire survey is conducted among the Safety Engineers, Site Engineers, Supervisors and Workers to elicit the actual happenings about the safety supervision in the site. The questionnaire mainly focused on safety supervision factors and Relative Importance Index (RII) is used to rank the safety factors. As a result, monitoring hoist operation (0.73), moving vehicle (0.72) and checking the stability of scaffolds (0.69) shows higher level of disagreement which means that these factors have been given least priority. In order to measure the strength of relationship between the respondents, Spearman’s Rank Correlation is done. Through the Spearman’s correlation it is known that Safety Engineers vs Supervisors (0.83) and Safety Engineers vs Site Engineers (0.81) has high correlation values which indicates that these respondents have provided similar rankings.
