Évaluation des actifs durables (SAVi) pour la voie de contournement de Rabat au Maroc: Gros plan sur les infrastructures routières

The report evaluates the 4.1 km Rabat bypass road, including the Mohammed VI bridge, using the SAVi tool to simulate six risk scenarios and four external factors. The analysis finds that the project is not financially viable based on its own revenues across all scenarios, as evidenced by negative Net Present Values (NPV) and insufficient Internal Rates of Return (IRR). However, integrating external factors—specifically the value of time saved and accident costs—significantly alters the cost-benefit analysis, demonstrating that conventional financial assessments underestimate the true risks and benefits of the infrastructure.

• The Rabat bypass road project is not financially viable when relying solely on its own revenues, regardless of the risk scenario modeled, showing a negative net present value (NPV) and an internal rate of return (IRR) below market rates for similar regional projects.
• Integrating external factors into the cost-benefit analysis (CBA) significantly changes the results; while the project appears balanced under conventional analysis, it shows negative results when the total cost of accidents is included, ranging from -8.6 million euros in the climate change scenario to -93.7 million euros in the increased roadworks scenario.
• External factors represent a substantial cost, accounting for between 13% and 19% of the expenses for operations and maintenance.
• Reducing maintenance spending by 5% (Scenario 2) leads to an increase in accidents, where the resulting economic and social costs far outweigh the savings achieved from reduced maintenance.
• Climate change impacts (Scenario 6), characterized by road damage on 2 km every 10 years, lead to a decline in all financial indicators due to the cumulative effect of frequent disruptions and the need for reconstruction.
• The value of time saved is one of the most significant external factors, with cumulative savings of 162.6 million euros between 2018 and 2060 in the baseline, reduced maintenance, and heavy vehicle increase scenarios.
• Increased heavy vehicle traffic (Scenario 5), with a 30% increase between 2018 and 2030, results in the highest operational and maintenance cost increase, rising by 8.40% compared to the baseline due to accelerated pavement degradation.
• The social cost of carbon is estimated at 31 US dollars per ton of CO2 emissions generated, and its value increases in scenarios involving more frequent road maintenance and reconstruction.
