2. Compare and contrast how the projects/infrastructure described have changed over time. Do you think that there is evidence from one book to the next, considering the timeline described in each, that the built environment is improving, or that people otherwise learned lessons from previous projects/infra-structure to improve the built environment and people’s lives? You are encouraged to think broadly about this question, including but not limited to issues related to quality of buildings, materials and methods used; human, health, safety, and environmental impact; how the public and/or private sectors organized to design, build, and maintain the projects/infrastructure described.3. Compare and contrast the impact of other factors had on these projects/infra-structure (such as bad luck, location, current events, political systems, economic markets, social norms at the time, etc. – things other than the way the places were built).4.Compare and contrast the ways in which the built environment described affected the society and people’s lives at the time? You can work from your answers to these questions in your individual reports (be specific, and argue from evidence).5. In what SPECIFIC ways do you think things would be different if the projects/infra-structure were built today?
