Abstract
Off-site manufacturing (OSM) offers a wide range of benefits to the construction industry by saving time, reducing waste, being an environmentally friendly solution, and providing a much safer onsite environment. However, safety management of OSM has become a concern due to the worker-related safety issues, which increase the safety incidents in off-site factories. However, research on the safety of OSM activities within a factory environment are still very limited. Therefore, this study aims to examine the interrelationships among worker-related safety factors and their influence on OSM safety performance. A probabilistic model based on Bayesian networks (BNs) to assess the influence of worker-related safety climate factors on OSM safety performance is utilized in this research study. A comprehensive review and evaluation of causal safety factors with the support of a questionnaire survey with OSM industry practitioners are the basis for this BN model. The proposed BN model is then verified by conducting a sensitivity analysis such as tornado diagrams and derivatives of sensitivity. The established model presents probabilities associated with different states of safety factors and identifies the interrelationships among worker-related safety climate factors and OSM safety performance. The research findings show that improvements in management safety response, coworkers' safety values and practices, and quality of training exert a greatest effect on the safety performance. Analysis further indicates that a balance between safety and production significantly affects workers' safety knowledge. This study contributes to the OSM safety domain by offering an effective tool to predict safety performance.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
