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.

Investigation of multi-level safety culture in the Indian construction industry: a multi-level employees' perception-based approach.

Inadequate compliance with safety practices is a major hurdle in the construction industry, and a single-level source of input to assess safety culture is a major limitation of the literature. Therefore, this study aimed to capture multi-level employees' (top management, middle management and workers) perceptions to assess multi-level safety culture (organizational level, project level and personnel level) in the construction industry. This study considered the Indian construction industry as the study area and used a questionnaire survey and interview technique as research instruments. In total, 184 responses were collected from multi-level employees. Data analysis was performed using a descriptive statistical method and hypothesis testing using the Mann-Whitney U test followed by the Kruskal-Wallis and post hoc tests. Findings highlighted inadequate safety compliances and significant (p < 0.05) perception differences among multi-level employees. Further, root cause analysis for observed perception differences was performed, and managerial implications were discussed from implementation perspectives.
