Q5.18: In the rules it states: “Additionally, the architect specified that there should be no bulky columns so that the building can maintain an airy look”. What is meant by a “bulky column”? The use of “bulky columns” would still be allowed right, it’s just not preferred?

A: The term “bulky columns” in the problem statement generally refers to bundle columns, where vertical frame members are spaced very close together to increase overall column dimensions.  The bolded sentence in Section 5.2.a of the Official Rules imposes a minimum spacing of vertical frame members, essentially disallowing the use of bundle columns consisting of tightly spaced frame members.  All kinds of columns are allowed as long as they satisfy the requirements stated in the Official Rules.
