||The Building Code and its associated regulations, standards, interpretations, rulings and explanatory support documents form a body ofmaterial which, like any law and its regulations, are complex and, attimes, esoteric. It is comprised of a series of concepts and their relationships, rules, exceptions to rules and examples. It essentially defines prescriptive states, conditions and actions for the builder/designer or identifies performance requirements for materials or systems.There is seldom rationale for the rules that could easily be understood and thus few answers to the question, "Why?". This makes building regulations difficult to develop, to use and to enforce. In this paper some applications of computers used in the Code Development process, as a user tool and as an instructional tool will be discussed.
