Construction safety performance measurement using a leading indicator-based jobsite safety inspection method: case study of a building construction project.

The construction industry is one of the hazardous industries all over the world. There have been continuous safety efforts on post-facto safety investigations and related corrective actions. However, to prevent future accidents, post-facto reports may not be able to provide comprehensive insights. Also, past literature pointed at limited proactive efforts to measure the current level of safety at the project. Therefore, this study introduced a leading indicator-based jobsite safety inspection (JSI) method to measure the project's safety performance. A total of 781 observations were reported in baseline and follow-up JSI on a real construction site. The study's findings highlighted an increase in safe behavior and conditions (SB&C) by reducing unsafe behavior (UB) and unsafe conditions (UC). Results confirmed a significant improvement in the safety performance index (SPI) of the case study from 39.07 to 67.47%. This study also investigated hazardous locations and weak safety dimensions for further SPI improvement. [ABSTRACT FROM AUTHOR]
