Estimation of accident prevention costs in construction using a statistical model

Resumo

Estimating accident prevention costs during the planning phase is essential for occupational safety in construction, yet data on these costs are scarce. This study analyzes and estimates prevention costs in vertical residential projects using data from 17 construction budgets. Statistical analyses, including covariance, correlation, scatter plots, and linear regression, assessed the relationship between costs and the equivalent construction area. Results indicate that prevention costs account for 2.93% of total project costs, with a strong negative correlation between average cost and equivalent area. The regression model explains 74.82% of cost variance, allowing early estimates with minimal effort. Despite the limited sample, this study contributes to Brazilian literature, providing insights for budget planning and suggesting future research with larger samples and additional variables.
