Cost-benefit analysis (CBA) is a crucial decision-making tool in environmental engineering, especially for large-scale projects like the construction of an airport. This analysis helps to weigh the costs against the benefits, providing a quantifiable measure to determine whether the project is economically viable and environmentally sustainable. Costs Direct Costs: • Construction: $500 million for building runways, terminals, and other facilities. • Environmental Mitigation: $50 million for pollution control, waste management, and habitat restoration. • Operational: $20 million annually for energy, maintenance, and staffing. Opportunity Costs: • Land Use: $100 million potential revenue from alternative commercial or residential development. • Economic Activities: $10 million annually from industries displaced by airport construction. Benefits Profits: • Aviation Fees: $30 million annually from landing fees, terminal fees, and airline charges. • Commercial Revenue: $25 million annually from retail, restaurants, and parking. Expected Economic Benefits: • Job Creation: $15 million annually from new employment opportunities. • Tourism Boost: $20 million annually from increased tourism spending. • Business Growth: $10 million annually from new businesses and investments. Other Desirable Outcomes: • Improved Transportation Infrastructure: Estimated benefit of $25 million annually from enhanced connectivity and reduced trav el times. • Environmental Benefits: Long-term benefits valued at $5 million annually from sustainable practices. Cost-Benefit Analysis Summary Table Component Costs ($ million) Benefits ($ million) Direct Costs $550m initial + $20m annual - Opportunity Costs $100m initial + $10m annual - Profits - $55m annually Expected Economic Benefits - $45m annually Other Desirable Outcomes - $30m annually Conclusion By conducting a cost-benefit analysis, environmental engineers can determine the economic viability and sustainability of the airport construction project. This analysis helps balance the direct and opportunity costs against the potential profits, economic benefits, and other desirable outcomes. In the case of the airport, the total annual benefits ($130 million) significantly outweigh the combined annual costs, justifying the project from both an economic and environmental perspective. This structured approach ensures informed decision-making, promoting sustainable development and longterm profitability.
