"A project such as this allows the industry to move from Research to Practice"
Presidents Award
for Excellence in
Engineering (AISC)
Award of Excellence
(SEAOC)
"The design process
exemplifies a successful
collaboration of performancebased engineering and
rigorous peer review by a
panel of noted experts, in
each structural system type.
The result minimizes the cost
and construction schedule
while maximizing the interior
space available for
architectural programming.“
