Boston's Central Artery/Tunnel Project, a 7.8 mile system of bridges and underground highways and ramps, is the most expensive public works project ever undertaken in the United States. The original cost estimate of $2.6 billion has already been exceeded by $12 billion, and the project will not be completed until 2005, seven years late. The Massachusetts Turnpike Authority (MTA), the public steward of the project, requested that the National Research Council carry out an independent assessment of the project's management and contract administration practices, with a focus on the present situation and measures that should be taken to bring the project to a successful conclusion. This report presents the committee's findings and recommendations pertaining to cost, scheduling, and transitioning from the current organization dominated by consultants to an operations organization composed largely of full-time MTA staff. The report recommends that MTA establish an external, independent, peer-review program to address technical and management issues until the transition to operations and maintenance is complete; begin a media campaign now to teach drivers how to use the new system safely; and develop, immediately implement, and maintain a comprehensive security program.
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
Drawing together a range of international experience in the techniques of planning, design and construction of submerged tubes, this book looks at the many uses of these tunnels - outside their principal application for rail or vehicular traffic - such as services, effluent outfalls, etc.
An illustrated account of the creation of the Charles River Basin, focusing on the precarious balance between transportation planning and the stewardship of the public realm. The Charles River Basin, extending nine miles upstream from the harbor, has been called Boston's "Central Park." Yet few realize that this apparently natural landscape is a totally fabricated public space. Two hundred years ago the Charles was a tidal river, edged by hundreds of acres of salt marshes and mudflats. Inventing the Charles River describes how, before the creation of the basin could begin, the river first had to be imagined as a single public space. The new esplanades along the river changed the way Bostonians perceived their city; and the basin, with its expansive views of Boston and Cambridge, became an iconic image of the metropolis. The book focuses on the precarious balance between transportation planning and stewardship of the public realm. Long before the esplanades were realized, great swaths of the river were given over to industrial enterprises and transportation—millponds, bridges, landfills, and a complex network of road and railway bridges. In 1929, Boston's first major highway controversy erupted when a four-lane road was proposed as part of a new esplanade. At twenty-year intervals, three riverfront road disputes followed, successively more complex and disputatious, culminating in the lawsuits over "Scheme Z," the Big Dig's plan for eighteen lanes of highway ramps and bridges over the river. More than four hundred photographs, maps, and drawings illustrate past and future visions for the Charles and document the river's place in Boston's history.
Archaeological sites often seem to be idyllic, even romantic, places where scientists recover and analyze fascinating data that can inform us of past times and the past lives of our recent historical and ancient prehistoric human forebears. Too often, however, unrecognized dangers lie within: bacterial and viral infections hidden in the soil, concealed in the animals that roam through our sites, or even lying in wait in organic remains we excavate; toxic substances produced by the historical technologies we study and that continue to poison the sites where people once worked; the bodies of people who died of historical scourges that once afflicted humanity and whose excavated mortal remains may still harbor the pathogens that killed them, dormant and lying in wait for an unsuspecting and largely no-longer immune modern population. It's enough to make an archaeologist swear off fieldwork! The truth is, however, that archaeologists need to be alerted to the dangers present in fieldwork and advised of the reasonable precautions that should be taken to insure the safest possible working environment. Dangerous Places brings together an enormous body of information regarding the threats that archaeologists face every day, and the best ways of behaving proactively to avoid or mitigate these threats.
