| Benchmarking Review Review construction safety documents and processes of CII member companies to identify current hazard recognition practices and innovative/emerging techniques Brainstorming session Conduct brainstorming sessions with expert panel of construction safety professionals to identify key factors and attributes that may improve hazard recognition PHASE 1 Identify hazards in case environments with expert panel Observe and measure hazard recognition and planning sessions with workers in case environments (Baseline phase) Introduce new hazard recognition strategy Observe and measure hazard recognition and planning sessions with workers in case environments (Baseline phase) PHASE 3 Reporting Produce guidelines and resources for effective implementation of highly effective strategies Produce research reports PHASE 4 Short-List Strategies in Focus Groups Identify 3 highly effective programs to field test and evaluate Longitudinal Measurement 7 Phase 4: Data Analysis and Reporting After the experimentation of the strategies with active work-crews and data collection, rigorous statistical analysis using simple interrupted time-series analysis for the multiple baseline technique dataset and two sample test for independent measures was conducted with the obtained data. Keeping with scientific convention, our testable hypothesis was stated in the negative. Our testable hypothesis was that the key strategies will not statistically increase the proportion of hazards identified by workers on dynamic construction sites. DISSERTATION FORMAT The dissertation is organized in a four journal paper format. That is, each of the four subsequent chapters represents independent articles that are submitted or under review in peer-reviewed academic journals. Therefore, each of the chapters contain their own abstract, motivation and background, theoretical and practical contributions, research methods, conclusions, future research endeavors, and referenced articles. The dissertation concludes with Chapter 6, which summarized the overall contribution of this study to theory and practice, and the recommended future research. Apart from the four journal papers, two journal publications that resulted from other concurrent research is presented in the Appendix. Four of the presented articles have been published I peer-reviewed academic journals, and the other two are currently under review. Chapter 2 presents Phase I of this study. The chapter presents research in which promising site- based construction hazard identification strategies were identified from a wide body of literature and potentially breakthrough strategies were developed by an expert panel of construction safety professionals in brainstorming sessions. The strategies were then prioritized based on their 8 potential and applicability using the Nominal Group Technique (NGT), facilitated by a group- decision support system. Consensus analysis was conducted to verify consistency within the expert panel. The three most promising strategies were identified for field testing in the subsequent phases. The findings of this phase were published in the Journal of Safety Health and Environmental Research. Chapter 3, 4, and 5 presents the development, field testing, and the analysis results of the three strategies that were identified by the expert panel (Phase 2, 3 & 4). Chapter 2 presents the results of a high fidelity augmented virtuality environment designed for the training phase (submitted to Journal of Construction Engineering and management), Chapter 3 presents a safety meeting maturity model designed for the planning phase (published in Journal of Construction Engineering and management,), and Chapter 4 presents a hazard identification and transmission board designed for the execution phase (submitted to Construction Management and Economics). Chapter 6 summarizes the motivation of this research study, the important contributions to both theory and practice, and provides recommendations for future research. Following Chapter 6, the data from each case study and some sample calculations are provided in the Appendix. Download 2.75 Mb. Share with your friends:
