Sustainable infrastructure is defined for this Unit as the designing, building, operating, maintaining, rehabilitating, and decommissioning of infrastructure structural elements over their life cycles. Definitions may vary both nationally and internationally. Infrastructure includes such as transport, public health, water, sewage treatment, energy, and telecommunication that are critical to the sustainability of communities. The Unit provides a broad treatment of the many facets of sustainable infrastructure including the role of asset management, integrated design, smart structures, sensing technologies, performance monitoring, the impact of changing environments and the life-cycle approach to infrastructure planning and management. Research skills will be developed through extensive literature surveys and communication skills evaluated though a Case Study.
