Application of cost-benefit analysis methodology for fire safety measures in structural fire engineering
In fire safety engineering, cost-benefit analysis offers a systematic approach to determining whether the anticipated benefits of a fire safety measure justify its costs. Nonetheless, significant disparities persist in the methodologies employed for cost-benefit analysis, alongside a lack of quantitative data concerning the costs and economic impact of fire protection in buildings. In a recent research project, a reference methodology was suggested, based on the concept of Present Net Value (PNV) assessment and a combination of specialized construction database, fire statistics, and numerical modelling for estimation of the cost components. This study presents the application of this methodology to a specific case study related to structural fire engineering. The case study illustrates the implementation of the methodology to a nine-story office building, as well as data gathering, examination of fire statistics, and loss estimation, while it also demonstrates how the methodology aids decision-making when evaluating multiple design alternatives. The cost-benefit analysis considers various thicknesses of Sprayed Fire Resistive Material (SFRM) applied to the building steel gravity frames corresponding to 1-hour, 2-hour, and 3-hour of fire protection. For all cases, the estimated benefit of the investment in fire protection on the steel members exceeds the cost. For the specific case study, the use of a 3-hour fire rated thickness is found as providing the highest benefit, and the sensitivity analysis confirms the robustness of the investment recommendation.
