SCHOOL OF BUILDING
CONSTRUCTION
College of Architecture
 GRADUATE FACULTY 1984-85
Director: B. H. Brown. Graduate Coordinator: R. E.
Cox. Professors: B. H. Brown; R. E. Cox; R. E. Crosland;
B. G. Eppes; D. A. Halperin; H. F. Holland; J. M. Trim-
mer. Associate Professor: C. D. Zeigler.
 Courses are offered leading to the degrees of Mas-
ter of Science in Building Construction (thesis) and
Master of Building Construction (nonthesis). An indi-
vidual 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 construction, materials, techniques, and struc-
tural concepts.
. There is no foreign language requirement. AIIBCN
graduate students are required to take an examina-
tion 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 prerequi-
site course or courses in English to ,he student's plan
of study. The examination must be taken during the
first registration period that the student is enrolled.
 Holders of a four-year undergraduate degree in
building construction or its equivalent in related
fields may normally complete the requirement for the
master's degree in one academic year (two semesters)
as full-time students. "Equivalent in related fields"
should include studies in construction materials and
methods, structures, and management. Students with
deficiencies in these related fields may need longer
residence for the master's degree, as they will be re-
quired to take specified basic courses to provide a
foundation for advanced courses.
 No more than five credits of BCN 6934 or 6971 may
