Twenty-eight projects, comprising six bridges and 22 buildings throughout North America, were named winners in the 2010 PCI Design Awards competition sponsored by the Precast/Prestressed Concrete Institute.
“These outstanding projects were singled out for extraordinary design, attention to detail, innovation, speed of construction, and industry advancement,” says Vijay Chandra, transportation jury member and senior vice president of Parsons Brinckerhoff.
“The wide range of entries highlights the versatility of precast concrete systems and the innovative ways in which engineers are using the advantages of precast concrete to meet today’s design challenges.”
Of the 28 winning projects, six highway and nonhighway bridges were selected in the annual competition.
Three additional bridge projects received honorable mentions.
From the Midwest region, Fulton Road Bridge Replacement in Cleveland, Ohio, was selected as the winner in the Bridges (Main span more than 150 ft) category.
The engineer of record was Michael Baker Jr. Inc., Cleveland, and precast components were provided by Carr Concrete, Waverly, W. Va., and Prestress Services LLC, Lexington, Ky.
Spanning a zoo, park and railroad lines, this bridge replacement consists of six 210-ft spans. To maintain zoo operations, precast, post-tensioned parabolic arch rib segments were fabricated in 59-ft pieces and erected using only three shoring towers per span.
Span segments contain post-tensioning tendons to enhance long-term durability. Precast I-girders support a cast-in-place deck.
Judges for the 2010 PCI Design Awards consisted of three panels focusing on bridges; buildings; and special awards for sustainability, all-precast solutions, and the Harry H. Edwards Award for industry advancement.div id="articleExtras"
