Lee, M; Jeong, J and Lee, J (2025) Development of a quantitative assessment method for occupational accident risk of construction workers using resource and cost information in the preconstruction stage. Journal of Construction Engineering and Management, 151(12): 04025208, ISSN 0733-9364
Abstract
The construction industry is one of the high-risk industries. One of the reasons why the construction industry is risky is that it involves a mix of different types of work and different types of workers. These risks are further influenced by the specific types of work and quantities required at various stages of construction projects. In response, this study proposes a new quantitative risk assessment method to enhance safety management in the preconstruction stage of the construction industry. This method integrates resource data derived from the Bill of Quantities and current standards for construction estimating to evaluate the probability of accidents and the risk cost by occupations type for workers at all stages of construction. This approach evaluates the safety risk of a particular worker by quantitatively comparing the baseline resource requirement (BRR) and the input resource requirement (IRR). The model was analyzed in a real-world application by conducting a case study on the construction of a steel structure. The analysis showed that the accident risk cost (ARC) of the IRR was 25% lower than that of the BRR, indicating improved safety at the design stage. The results of this study provide useful insights for prioritizing safety in the design and estimation stages and have the potential to be widely applied to various construction scenarios.

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
