3. The currrent legal system encourages architects to require structural
engineers, detailers, and fabricators to do which?
a. use the architect’s schematic computer model
b. reduce the cost of redundant model building
c. create their own 3D computer models
d. share the cost of 3D computer models

4. The NBBJ 3D modeling exercise did not pay off in which way?
a. cutting sections
b. spotting conflicts
c. raising significant design issues earlier in the design process
d. expanding and contracting the model

5. Which did not contribute to the use of less steel and fewer welds in the design of the complex stairs?
a. the cacophony of forms
b. test loading diagrams
c. distribution of uniform loads
