| specifically tailored to the construction industry. Specifically, this study (1) identified promising proactive hazard recognition strategies being implemented in various industries (2) identified what industry experts believe are the three most promising strategies based on established decision criterion (3) developed and refined the strategies and associated implementation tools and (4) field tested and analyzed the strategies with active crews to measure performance and response in real-life scenarios using the multiple baseline testing technique and interrupted time series regression analyses techniques. This dissertation provides a rationale for conducting studies to improve the hazard recognition levels, provides details on the designed strategies, details the multiple baseline based field testing approach, and discusses the analyses techniques and research findings. In the first phase, promising strategies were identified through an extensive literature search, review of construction safety documentation and a panel of 12 domain experts. Subsequently, a down- selection process based on pre-established implementation attribute criterion and group consensus from the expert panel was conducted to identify the three most promising strategies that may feasibly be tested on active crews. The three strategy elements that emerged as being potential and testable were (1) the pre-job safety meeting quality measurement (SMQM) maturity model, (2) a System for Augmented Virtuality Environment Safety (SAVES) program, iv and the (3) visual cue based Hazard Identification and Transmission (HIT) board. These chosen hazard identification strategies, in the second phase, were then further developed through brainstorming sessions with the expert panel and through questionnaire surveys. In the third phase, six independent empirical multiple baseline longitudinal studies was conducted with three active work-crews to test the effects of introducing the devised strategies on dynamic construction environments. The multiple baseline study results were used to test the null hypothesis that the intervention does not improve the proportion of hazard identified and Download 2.75 Mb. Share with your friends:
