Collapse of I-35W Highway Bridge, Minneapolis, Minnesota, August 1, 2007


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.




Losing Our Way


Book Description

From longtime New York Times columnist Bob Herbert comes a wrenching portrayal of ordinary Americans struggling for survival in a nation that has lost its way In his eighteen years as an opinion columnist for The New York Times, Herbert championed the working poor and the middle class. After filing his last column in 2011, he set off on a journey across the country to report on Americans who were being left behind in an economy that has never fully recovered from the Great Recession. The portraits of those he encountered fuel his new book, Losing Our Way. Herbert’s combination of heartrending reporting and keen political analysis is the purest expression since the Occupy movement of the plight of the 99 percent. The individuals and families who are paying the price of America’s bad choices in recent decades form the book’s emotional center: an exhausted high school student in Brooklyn who works the overnight shift in a factory at minimum wage to help pay her family’s rent; a twenty-four-year-old soldier from Peachtree City, Georgia, who loses both legs in a misguided, mismanaged, seemingly endless war; a young woman, only recently engaged, who suffers devastating injuries in a tragic bridge collapse in Minneapolis; and a group of parents in Pittsburgh who courageously fight back against the politicians who decimated funding for their children’s schools. Herbert reminds us of a time in America when unemployment was low, wages and profits were high, and the nation’s wealth, by current standards, was distributed much more equitably. Today, the gap between the wealthy and everyone else has widened dramatically, the nation’s physical plant is crumbling, and the inability to find decent work is a plague on a generation. Herbert traces where we went wrong and spotlights the drastic and dangerous shift of political power from ordinary Americans to the corporate and financial elite. Hope for America, he argues, lies in a concerted push to redress that political imbalance. Searing and unforgettable, Losing Our Way ultimately inspires with its faith in ordinary citizens to take back their true political power and reclaim the American dream.

Megaproject Management


Book Description

Project management lessons learned on the Big Dig, America's biggest megaproject, by a core member responsible for its daily operations In Megaproject Management, a central member of the Big Dig team reveals the numerous risks, challenges, and accomplishments of the most complex urban infrastructure project in the history of the United States. Drawing on personal experience and interviews with project engineers, executive oversight commission officials, and core managers, the author, a former deputy counsel and risk manager for the Big Dig, develops new insights as she describes the realities of day-to-day management of the project from a project manager's perspective. The book incorporates both theory and practice and is therefore highly recommended to policymakers, academics, and project management practitioners. Focusing on lessons learned, this insightful coursebook presents the Big Dig as a massive case study in the management of risk, cost, and schedule, particularly the interrelation of technical, legal, political, and social factors. It provides an analysis of the difficulties in managing megaprojects during each phase and over the life span of the project, while delivering useful lessons on why projects go wrong and what can be done to prevent project failure. It also offers new ideas to enhance project management performance and innovation in our global society. This unique guide: Defines megaproject characteristics and frameworks Reviews the Big Dig's history, stakeholders, and governance Examines the project's management scope, scheduling, and cost management including project delays and cost overruns Analyzes the Big Dig's risk management and quality management Reveals how to build a sustainable project through integration and change introduction




Status of the Nation's Highways, Bridges and Transit: Conditions and Performance


Book Description

This Conditions and Performance (C&P) report is intended to provide decision makers with an objective appraisal of the physical conditions, operational performances, and financing mechanisms of highways, bridges, and transit systems based both on the current state of these systems and on the projected future state of these systems under a set of alternative future investment scenarios. This report offers a comprehensive, data-driven background to support the development and evaluation of legislative, program, and budget options at all levels of government. This report consolidates conditions, performance, and financial data provided by States, local governments, and mass transit operators to provide a national-level summary. Illus.







Unexpected Consequences


Book Description

In this book, interrelationships between more than 40 recent catastrophic events are explored, discussing failures of structures and machines, information technology, regulatory agencies, security designs, and more. The world is full of wonderful products and services that occasionally disappoint and even harm us. Unexpected Consequences: Why The Things We Trust Fail explores the reasons these failures occur, examining them from technological, human, and organizational perspectives. Using more than 40 recent catastrophic events to illustrate its points, the book discusses structural and machine failure, but also the often-overlooked failure of people and of systems related to such things as information technology, healthcare, and security. As the book demonstrates, faulty technology played a surprisingly small part in many of the scrutinized disasters. Author James William Martin finds cognitive factors and organizational dynamics, including ethics, are major contributors to most unexpected and catastrophic failures causing loss of life and extensive property damage. With that fresh perspective in mind, Martin is able to suggest remedies that address service failure and just may help prevent future disasters from taking place.




Gridlock


Book Description

America is the most mobile society in history, but our transportation system is on the verge of collapse. Traffic congestion is today five times greater than it was 25 years ago, yet many transportation plans and projects are making it worse. As Randal O’Toole reveals in Gridlock, the prime causes of our ailing system are a government transportation planning philosophy whose primary goal is to diminish auto use—hence, personal mobility—in combination with federal budget incentives that perversely encourage transportation planners to increase congestion. As a result, the automobile which is accessible to almost every family in the nation and provides unparalleled access to better housing, low-cost consumer goods, a choice-driven affordable life, and freedom—is being deliberately forced off the transportation grid by the expensive “solution” of little-used high-speed trains and urban transit lines. Gridlock presents a wide range of innovative ideas and policy recommendations for creating an effective transportation system—improvements that will increase our mobility and pay for themselves, whether it’s cars, buses, planes, or trains. At the center of O’Toole’s solutions are three core principles: those who use transportation facilities should pay for them; negative effects should be dealt with in a cost-efficient manner; and new technologies that will increase mobility at a low cost must be embraced. In Gridlock, Randal O’Toole brings energetic and unconventional thinking to transportation strategies that have, until now, only driven us into the breakdown lane.
