Since then, he\u2019s produced six episodes, each 20\u201330 minutes, exploring events including the Florida International University pedestrian bridge collapse and the sinkhole that opened beneath the National Corvette Museum in Ohio, swallowing eight vintage Corvettes.<\/p>\n<p>\u201cI\u2019d been producing a show that covered four stories in 44 minutes, and the engineering tended to get short shrift,\u201d Gorham said. Although he studied biology in college, he became increasingly interested in how bridges, buildings, and machines work, and how they can unravel.<\/p>\n<p>For the Fern Hollow Bridge collapse, Gorham turned to Harries, PhD, FASCE, FACI, FIIFC, P.Eng at Pitt\u2019s Swanson School of Engineering, who has spent his career in forensic engineering. Harries has investigated structural collapses in many capacities and is regularly consulted by reporters, lawyers, and government officials.<\/p>\n<p>After the Lake View Drive Bridge collapsed onto Interstate 70 in Washington County on December 27, 2005, Harries helped test the remaining girders and identify the source of the failure. He has provided forensic investigation about the Lowe\u2019s Motor Speedway pedestrian bridge collapse following a NASCAR event in May 2000 and has consulted in multiple capacities on the I\u201135W Mississippi River bridge collapse in Minneapolis in 2007. This summer, he will be conducting a review survey of glass\u2011fiber composite bridge decks in the Pittsburgh region.<\/p>\n<p>    &#8216;;<\/p>\n","protected":false},"excerpt":{"rendered":"&#13; &#13; &#13; WSF model&#13; &#13; Last year, with fellow producer Julian Watson, Gorham launched Why Stuff Fails&hellip;\n","protected":false},"author":2,"featured_media":192306,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[3892,12911,3893,3895,73,75,74,1164],"class_list":["post-192305","post","type-post","status-publish","format-standard","has-post-thumbnail","category-pittsburgh","tag-banner","tag-civil-environmental","tag-dept-banner","tag-pitt-swanson-school-of-engineering","tag-pittsburgh","tag-pittsburgh-headlines","tag-pittsburgh-news","tag-research"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts\/192305","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/comments?post=192305"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts\/192305\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/media\/192306"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/media?parent=192305"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/categories?post=192305"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/tags?post=192305"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
