To enhance workers’ protection in construction tasks, Occupational Health and Safety Risks (OHSR) needs to be properly recognized, assessed and controlled. This study modelled Health and Safety Risk (HSR) among unskilled workers in construction works. Data were collected from 150 subjects in 12 construction sites located in Southwest Nigeria. Variables considered to play key roles in HSR causation were measured with the questionnaire. All variables that correlated significantly (p≤ 0.05) to HSR on the tasks were noted by Spearman’s rho correlation (Src) using SPSS software. The model prediction was adjusted by R2 and was validated by comparison with Human Professionals’ Predictions (HPP). Model Cook’s distance and its closeness to being normally distributed were evaluated. 37 attributes variables were initially collated with 13 predictor variables remained in the optimum model. Wrong work-methods, lack of work-control and harsh outdoor environment ranked among the strongest positive β coefficients (0.217, 0.127 and 0.126 respectively). The maximum coefficient of the adjusted R2 determination was 0.708. The histogram of the residuals suggested closeness to being normally distributed and 0.930 as the maximum Cook’s distance. Comparison between the OHSR model and the HPP had strong Src strength. The OHSR showed a statistically significantly higher level of hazards’ rating compared to HPP. OHSR model was developed and the performance was rated good, satisfied the study’s objectives. The author recommended the development of measures at reducing β coefficients of all the predictor variables to minimize workplaces OHSR.
