not having enough course material. Parts of various textbooks can be used for instruction on general methods and tools and discussion of case studies [Moavenzadeh 1994, Graedel 1995]. Text on specific construction design and engineering problems also exists (see, e.g., [FHWA-EPA 1993, DOT 1993, Horvath 1998a, Horvath 1998b]). Examples from environmentally more mature industries (such as the electronics and the automobile sectors) may also be used for illustration of basic concepts and systems approaches.
