This course builds on the foundations introduced in the Principles of Sustainability I course, moving from principles and theory toward applied decision-making in civil engineering practice. Students will examine how economic analysis informs the design, construction, and management of sustainable infrastructure, with emphasis on lifecycle assessment, cost–benefit trade-offs, and resilience planning. Tools for evaluating environmental, social, and economic impacts are applied to real-world civil engineering projects, highlighting the challenges of balancing growth, equity, and environmental stewardship. Case studies, simulations, and applied exercises connect economic concepts directly to professional engineering decisions, with a particular focus on Canadian and global sustainability goals.
