Before the double-curved inverted Fink truss design was selected, it was evaluated against nine other structure options, comparing a long list of design objectives that included user comfort, compatibility with construction restrictions, cost and the feasibility of meeting UVU’s August 2019 construction deadline.
“It was compared against more traditional structure types, like prefabricated trusses, but because of the span length, width and requirement for a roof, this was actually the least expensive alternative,” Cooper said.
The efficient use of materials and limited superstructure depth of the inverted Fink truss also provides advantages over other bridge types, said Cooper, who added that the aesthetic appeal is preferable to other designs.
“As arranged, the roof appears to float above the deck instead of having a bridge with a roof or enclosure simply added to it,” he said.
Before settling on the atypical structure design, it was critical to get all three client agencies comfortable with the concept. The design team made every effort to address technical issues and looked ahead to all possible construction challenges before the design was selected.
“There has been and will continue to be a lot of collaboration on the project with our three clients and our subconsultant team, including the architect, Method Studio, and the construction contractor, Kraemer North America,” Cooper said.
