SCHOOL OF BUILDING CONSTRUCTION College of Architecture GRADUATE FACULTY 1989-90 Director: W. P. Chang. Graduate Coordinator: R. E. Cox. Professors: G. S. Birrell; B. H. Brown; A. J. Catanese; W. P. Chang; R. E. Cox; R. E. Crosland; B. G. Eppes; D. A. Halperin; H. F. Holland; J. M. Trimmer. Assistant Profes- sor: R. A. Furman. In addition to the Doctor of Philosophy degree adminis- tered at the College of Architecture level emphasizing construction management, courses are offered leading to the degrees of Master of Science in Building Construction (thesis) and Master of Building Construction (nonthesis). An individual plan of study is prepared for each student to insure that the student's goals are achieved within the broad policy guidelines of the school. Specialization may be in areas such as the construction manager concept, planning and scheduling, cost control, high rise construc- tion, materials, techniques, and structural concepts. There is no foreign language requirement. All BCN graduate students are required to take an examination on their ability to communicate in the English language. Failure to make a satisfactory score on this examination will result in the addition of a prerequisite course or courses in English to the student's plan of study. The examination must be taken during the first registration period that the student is enrolled.
