Stout for the TxDOT Bridge Division focuses on the critical importance of Quality Assurance and Quality Control (QA/QC) in structural bridge engineering. By analyzing the catastrophic collapse of the I-35W bridge over the Mississippi River as a primary case study, the document highlights how insufficient design firm oversight, inadequate load rating practices, and lack of construction inspection guidance directly contribute to infrastructure failure. It outlines mandatory programmatic implementations, including load rating requirements, gusset plate evaluation, and rigorous oversight of construction loading, to ensure public safety and structural integrity. The document serves as a foundational guide for design professionals to implement robust QA/QC workflows, maintain proper documentation, and adhere to national highway safety standards established by transport authorities.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/qa-qc-in-bridge-design-getting-it-right/649602/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/qa-qc-in-bridge-design-getting-it-right/649602.png","ImageObject",300,407,{"name":92,"@type":93},"Fahsai","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-25","2026-10-24",true,{"@type":102,"interactionType":103,"userInteractionCount":8},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What are the primary reasons for the I-35W bridge collapse mentioned in the report?","Question",{"text":112,"@type":113},"The collapse was attributed to factors including insufficient design firm quality control, failure to account for construction loads, the exclusion of gusset plates in load ratings, and inadequate inspection practices.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What recommendations did the NTSB make following the I-35W bridge accident?",{"text":117,"@type":113},"The NTSB recommended implementing formal design QA/QC programs, mandating load ratings for new bridges, evaluating gusset plates during ratings, and controlling construction activities to prevent structural overloading.",{"name":119,"@type":110,"acceptedAnswer":120},"Who is the presenter and for what occasion was this content developed?",{"text":121,"@type":113},"The content was presented by Thomas C.
