Leading or lagging? Temporal analysis of safety indicators on a large infrastructure construction project
Safety performance data collected over a five year period, at a large Australian infrastructure project was analysed. The analysis examined the temporal relationships between the safety performance indicators measured at the project, including traditional lagging indicators, as well as expected leading indicators. The purpose of the research was to uncover time dependent relationships and explore causal relationships between indicators. The analysis revealed complex interactions between safety indicators over time. Notably, the expected leading indicators behaved as both leading and lagging indicators...
Toward an understanding of the impact of production pressure on safety performance in construction operations
It is not unusual to observe that actual schedule and quality performances are different from planned performances (e.g., schedule delay and rework) during a construction project. Such differences often result in production pressure (e.g., being pressed to work faster). Previous studies demonstrated that such production pressure negatively affects safety performance. However, the process by which production pressure influences safety performance, and to what extent, has not been fully investigated. As a result, the impact of production pressure has not been incorporated much into safety management...
The effectiveness of a construction worksite prevention program on work ability, health, and sick leave
Objective This study aimed to investigate the effectiveness of a prevention program on work ability, health, and sick leave targeted at construction worksites. Methods A total of 15 departments (N=297 workers) from 6 construction companies participated in this cluster randomized controlled trial and were randomly allocated to the intervention (8 departments; N=171 workers) or control (7 departments; N=122 workers) group. The intervention consisted of two individual training sessions with a physical therapist aimed at lowering the physical workload, a rest-break tool to improve the balance between...
