This course, for students in the fourth semester of the MArchI program, raises basic issues arising in contemporary architectural practice. The course challenges the students to examine critically a broad range of professional, political, business, and ethical problems that they are likely to face in practice. Each unit focuses on a case study that describes the actual experience of an architect, including several architects of national and international reputation. The subjects of the cases include: obtaining a commission, controlling construction costs, conflicts between the client and the community, new forms of project delivery, monitoring a contractor\'s performance, working in another country, the challenges of sustainable design, methods of collaboration, the impacts of new technologies, and alternative career paths and models of firm practice. Three or four of the architects whose cases are studied visit the class as guest lecturers. Each unit contains material to supplement the case study, exposing the student to related topics such as the roles of professional organizations, standard AIA contract forms, government regulation and design review, the economics of practice, architectural competitions, etc. Many of the units also have companion exercises that present an ethical dilemma arising from professional practice for class discussion. Course requirements include participation in class discussions, a research paper, and a final exam. All course material is available without charge on the GSD website and in the library.
