The fatality rate in the construction industry is a key indicator for assessing safety management, with the number of workers being a critical factor in its estimation. Many countries rely on sampling inspections or assumptions to determine the number of workers, which can lead to inaccuracies in evaluating the fatality rate. In this study, we developed a method to calculate the full-time equivalent workers per man-year (FTEWm·y) to more accurately estimate the fatality rate, taking into account building and work types using daily work reports (DWRs). The research process included six steps: (i) selecting a target project; (ii) establishing a database; (iii) developing the FTEWm·y framework based on the DWR; (iv) validating the framework; (v) calculating the FTEWm·y for residential building projects in the Republic of Korea; and (vi) applying the framework. The key findings included the following: the FTEWm·y/USD for residential projects was 1.1 × 10−3 FTEWm·y/USD, with the framework achieving an accuracy of 85.30% and an R2 value of 92.92% through five-fold cross-validation. The FTEWm·y for residential buildings in the Republic of Korea was 4.5 × 107 FTEWm·y, and the fatality rate was 0.011‱. This framework offers a more precise way of evaluating fatality rates by considering specific building and work types, improving safety management practices in the construction industry.
