How Building Information Modeling Technology Supports Safety on Construction Sites: The Case Study of a Water Reservoir in Italy

Workplace safety, particularly in the construction industry, is a moral and legal imperative, prioritizing the protection of workers’ health and well-being. In Italy, Legislative Decree 81/08 (and subsequent modifications) serves as a regulatory framework for workplace safety, defining the duties of employers and employees and promoting accident prevention measures. Building information modeling technology, which has revolutionized the global construction industry by offering an integrated approach to design, construction, and management through intelligent digital models, has only recently started gaining traction in Italy as part of Industry 4.0. This article examines the potential of integrating the current prevention strategies with BIM technology to optimize safety design on construction sites. A case study demonstrates the use of the BIM software REVIT to model a water reservoir for an aqueduct, including structural and plant components, the surrounding context, and proposed construction site organization. The research methodology involves creating a contextualized 3D model to support preliminary safety assessments, work process organization, and the drafting of a safety and coordination plan. Through detailed analysis and critical discussion, this work contributes to understanding how the interaction of regulations and BIM technology can improve construction site safety, offering insights that are applicable beyond the Italian context to the global construction industry.
