Field of study

Pakistan is a developing country that is currently enjoying relatively substantial growth in construction activities. Unfortunately, Pakistan’s construction industry suffers from poor occupational safety and health (OSH) conditions. The framework of the existing OSH conditions is fragmented and inadequately enforced, making construction sites more hazardous. Therefore, it is essential to improve OSH conditions in order to improve safety performance in building construction. Thus, this research aims to find those significant safety parameters which can significantly enhance the onsite safety performance of high-rise building construction. Based on an extensive literature review, sixty (60) safety parameters for enhancing onsite safety performance have been identified and classified into fourteen (14) groups. In addition, this study also adopted a quantitative approach, whereby a questionnaire survey was carried out on two hundred and ten (210) respondents working in high-rise construction projects in Karachi city of Sindh Province, in order to determine the most significant safety parameters out of all the identified safety parameters. Initially, data analysis using SPSS version 26 found that 38 out of 60 safety parameters were the most significant safety parameters for enhancing onsite safety performance. Furthermore, the results from principal component factor analysis provided evidence for the eight (08) groups, consisting of 56 significant safety parameters accounting for 74.686% of the shared variance. Finally, correlation analysis results revealed that the 08 groups comprising 56 significant safety parameters exhibit small and medium (range from rs=0.247 to rs=0.334) correlation with onsite safety performance of high-rise building construction. This empirical analysis has provided a new framework of significant safety parameters for enhancing onsite safety performance of high-rise building construction. Therefore, focusing on these safety parameters would improve the employees’ safety, which will then enhance the overall safety performance on highrise construction projects. It is hoped that this research can positively benefit the Pakistani construction industry in enhancing the onsite safety performance of highrise buildings construction
