Book Description
In the early afternoon, construction equipment and construction aggregates (sand and gravel for making concrete) were delivered and positioned in the two closed inside southbound lanes. The equipment and aggregates, which were being staged for a concrete pour of the southbound lanes that was to begin about 7:00 p.m., were positioned toward the south end of the center section of the deck truss portion of the bridge and were in place by about 2:30 p.m. About 6:05 p.m., a motion-activated surveillance video camera at the Lower St. Anthony Falls Lock and Dam, just west of the I-35W bridge, recorded a portion of the collapse sequence. The video showed the bridge center span separating from the rest of the bridge and falling into the river.

Book Description
"A bridge shouldn't just fall down," Senator Amy Klobuchar said after the August 1, 2007, collapse of the Minneapolis I-35W eight-lane steel truss bridge, which killed 13 motorists, injured 145, and left a collective wound on the city's psyche and infrastructure. On her way to a soccer game with a fellow teammate, Kimberly J. Brown experienced the collapse firsthand, falling 114 feet in her teammate's car to the Mississippi River. Although terrified, injured, and in shock, she survived. In this sobering memoir and exposé, Brown recounts her harrowing experience. In the aftermath of the disaster, Brown became both an advocate for survivors and an unofficial whistle-blower about decaying infrastructure. She details her investigation and correspondence with Thornton Tomasetti engineers, including the false official account of the collapse and the eventual revelation of its real causes. In addition, she chronicles the ongoing decay of America's bridges and the continuing challenges faced by leaders to address infrastructure problems across the country. After nearly a decade of research into the collapse and her active and ongoing recovery from psychic and physical injuries, Brown shares her experience and answers the questions we should all be asking: Why did this bridge collapse? And what could have been done to prevent this tragedy?

Book Description
This open access book is about mismanagement of public agencies as a threat to life and limb. Collapsing bridges and buildings kill people and often leave many more injured. Such disasters do not happen out of the blue nor are they purely technical in nature since construction and maintenance are subject to safety regulation and enforcement by governmental agencies. This book analyses four relevant cases from Australia, New Zealand, the USA and Germany. Arguing that, while preventing disaster through public oversight is essentially easy, the difficult part for public officials and private contractors and consultants alike is to resist incentives that threaten professional skills and standards. Rather than stressing well-known pathologies of bureaucracy as a potential source of disaster, this book argues, learning for the sake of prevention should aim at neutralizing threats to integrity and strengthening a sense of responsibility among public officials.

Book Description
Recent surveys of the U.S. infrastructure’s condition have rated a staggering number of bridges structurally deficient or functionally obsolete. While not necessarily unsafe, a structurally deficient bridge must be posted for weight and have limits for speed, due to its deteriorated structural components. Bridges with old design features that cannot safely accommodate current traffic volumes, and vehicle sizes and weights are classified as functionally obsolete. Such deficiencies may adversely affect the performance of transportation systems in emergency situations or for disaster response. This narrative has become part of the public debate sparked by the collapse of the I-35W Bridge over the Mississippi River in Minneapolis, Minnesota, USA, on August 1, 2007. Ever since, numerous technical and news articles have been written to answer the persistent question, why did the bridge collapse? Exhaustive examination of the details of a specific bridge failure, typically, reveals the reasons for the collapse and lessons are drawn from the experience. Each bridge failure, since the Tacoma Narrows Bride disaster in 1940, has served as a wakeup call for the bridge engineering community, initiating radical changes in the design and construction standards. However, a paradigm shift is necessary in the inspection and monitoring practices of the bridge engineering community to provide preventive maintenance and restore the public’s confidence in the safety of bridges. Concerns about bridge safety and reliability go beyond geographical boundaries and are shared by bridge engineers from different countries. This book contains a number of selected papers that were presented at the Fifth New York City Bridge Conference, held on August 17-18, 2009. These papers cover a wide range of topics in the design, construction, maintenance, monitoring and rehabilitation of bridge structures.

Book Description
"In response to the infrastructure crisis in the U.S.--brought to the forefront by the Minneapolis bridge collapse and the devastation of Hurricane Sandy--Hillary Brown proposes a new way to approach infrastructure needs. The alternative approach proposed in this volume calls for more diversified, distributed, and interconnected infrastructure that integrates (and in some cases mimics) natural systems"--

Book Description
How a Michigan farm boy became the richest man in America is a classic, almost mythic tale, but never before has Henry Ford’s outsized genius been brought to life so vividly as it is in this engaging and superbly researched biography. The real Henry Ford was a tangle of contradictions. He set off the consumer revolution by producing a car affordable to the masses, all the while lamenting the moral toll exacted by consumerism. He believed in giving his workers a living wage, though he was entirely opposed to union labor. He had a warm and loving relationship with his wife, but sired a son with another woman. A rabid anti-Semite, he nonetheless embraced African American workers in the era of Jim Crow. Uncovering the man behind the myth, situating his achievements and their attendant controversies firmly within the context of early twentieth-century America, Watts has given us a comprehensive, illuminating, and fascinating biography of one of America’s first mass-culture celebrities.

Book Description
Gilt immer noch, dass ein Bauwerkseinsturz der beste Lehrmeister für den Fortschritt des Bauens ist? Oder, anders formuliert: Ist Bauen dann, wenn wir das Bewährte verlassen und Neues wagen, "Experimentieren"? Über die Ursache von Schadensfällen und Einstürzen, die oft mit dem Verlust von Menschenleben verbunden sind, wird nicht gern öffentlich gesprochen. Aber aus Fehlern kann man lernen. Die Lehren und Erfahrungen aus den Schadensauswertungen führen zu mehr Sicherheit und oft zum Innovationsschub. Die Kenntnis der Schadensursachen ist Voraussetzung für ihre zukünftige Vermeidung. Mit diesem Buch liegt eine systematische Zusammenstellung von über 400 Versagensfällen vor, die in besonderer Weise betrachtet werden: Sie werden nach dem Zeitpunkt ihres Auftretens im Lebenszyklus der Brücke, z. B. im Bauzustand oder im Betrieb, und nach den Schadensereignissen, z. B. Anprall oder Erdbeben, geordnet. Die wichtigsten Ursachen sind: menschliches Versagen, mangelnde Aussteifung, Materialversagen oder Überlastung. Es werden vorwiegend Brückeneinstürze, die in der Literatur wenig oder nach dem Urteil des Verfassers nicht vollständig oder nicht zutreffend behandelt sind, ausführlich analysiert. Mit Akribie gesammelt, kompetent und exzellent aufgearbeitet und mit Mut präsentiert, ergibt dies eine unverzichtbare Erkenntnisquelle für jeden Bauingenieur in der Praxis und für das Studium. Ein Katalog von Regeln wurde erstellt. Seine Beachtung kann helfen, Fehler bei Entwurf, Planung und Ausführung zu vermeiden.

Book Description
Long before he was considered a top prospective presidential candidate for 2012—even before he landed on John McCain’s short list of potential running mates in 2008—Governor Tim Pawlenty had already earned legendary status in conservative circles. In his hard-left-leaning home state of Minnesota, the man known as “T-Paw” somehow erased a $4.8-billion budget deficit while simultaneously reforming health care, creating jobs, improving education, and supporting renewable energy reform—all without raising taxes. In Courage to Stand, Pawlenty reveals, for the first time, how he found the resolve to get the job done, taking readers all the way back to the lessons he learned as a boy in the gritty meatpacking town of South St. Paul. From the devastating early death of his mother to the struggle to work his way through college and law school and his epic political battles as governor, Pawlenty opens up about his deepest beliefs and shares his vision for a better America.
