| 摘要： | When Greg Gorman, president and COO of PennStress, a precasting company based in Roaring Spring, Pa., was attending the annual meeting of PCI Mid-Atlantic in January 2022, he received word that a major bridge had collapsed in Pittsburgh, Pa. When the Fern Hollow Bridge in Pittsburgh's Frick Park collapsed, four people sustained non-life-threatening injuries. Had the bridge collapsed an hour later, during peak commuter time, it could have been a different story. Following the collapse, an emergency project team was assembled and given the green light to start working on the rebuild immediately. With conventional methods, replacing a bridge this size typically would have taken three to four years, plus the time required to redesign the bridge, plan the bridge construction, obtain approvals, prepare the site, and install substructure elements. Using prestresed concrete beams for the bridge superstructure assisted the Fern Hollow Bridge completion in less than a year. |
