Derrick (archivist, Bronx County Historical Society) tells the story of what was, at the time, the largest and most expensive single municipal project ever attempted--the 1913 expansion of the New York City Dual System of Rapid Transit. He considers the factors motivating the expansion, the process of its design, the controversies surrounding financing it, and its impact on New York then and today. Appendixes summarize the contracts and related certificates and list the opening dates of Dual System lines. Twenty-four pages of photographs are also included. c. Book News Inc.

It is a world turned upside down...a world created when a future time traveler re-directs the course of World War II. The United States has suffered six decades of oppressive fascist rule. Now, while a decimated band of expatriate American rebels fight to liberate their country, international dissension threatens a nuclear holocaust. Tony Shane--a rebel with a dangerous, incredible plan--has inherited wartime secrets that might free his country: a plan derived from Albert Einstein--whose cryptic legacy conceals an improbable time travel strategy. To unravel the secrets of "Einstein's tunnel," Shane persuades Sarah Stenstrom--a beautiful young scientist in a Nazi cyber-research laboratory--to join his cause. But their intimate relationship soon threatens the entire mission. Vito Mironi--a powerful mob boss within a corrupt Nazi regime--secretly supports the rebels. But the reality of Einstein's plan soon converts Mironi into Shane's most dangerous adversary. Joining Shane's desperate odyssey is a ruthless rebel assassin, Salomé, with a burning personal agenda. But only Nathan Carothers--charismatic rebel leader--knows the true dark purpose underlying their mission. Confronted by surprising obstacles, Tony Shane traverses a perilous path--while racing a deadly doomsday clock--to fulfill the promise of Einstein's Tunnel.

This Practical Guide to Rock Tunneling fills an important void in the literature for a practical guide to the design and construction of tunnels in rock. Practical Guide to Rock Tunneling takes the reader through all the critical steps of the design and construction for rock tunnels starting from geotechnical site investigations through to construction supervision. The guide provides suggestions and recommendations for practitioners on special topics of laboratory testing, durability of rock and acceptance for unlined water conveyance tunnels, overstressing or deep and long tunnels, risk-based evaluation of excavation methods, contract strategies, and post-construction inspections. Key considerations and lessons learned from selected case projects are presented based on the author’s extensive international experience of over 30 years and 1000 km of tunneling for civil, hydropower, and mining infrastructure, including some of the most recognized projects in the world to date. Instead of revisiting all theory and concepts that can be found in other sources, this book contains the hard learned lessons from the author’s experience in the field of Rock Tunneling, gathered over 30 years of service.

This publication includes papers from the North American Tunneling 2004 conference, sponsored by the American Underground Construction Association. The theme of the conference is "Underground Construction - the Sensible Solution to Urban Problems" to reflect the increasing importance of locating urban facilities in the United States underground for enhanced security, to build critical infrastructure where it is needed and to improve the function of urban areas. The papers are grouped in four major themes: - Management of Underground Projects - Public Policy and Underground Projects - Advances in Technology - Case Studies: Trials, Tribulation and Triumphs in Tunneling This work should benefit everyone involved in any aspect of infrastructure, tunneling and underground construction.

The North American Tunneling Conference is the premier forum to discuss new trends and developments in underground construction in North America. With every conference, the number of attendees and breadth of topics grows. North American Tunneling: 2014 Proceedings reflects the theme for the 2014 conference, “Mission Possible.” The authors share new theories, novel innovations, and the latest tools that make what once may have been perceived as impossible, now possible. The authors of 128 papers share the latest case histories, expertise, lessons learned, and real-world applications from around the globe on a wide range of topics. They cover the successes and failures of challenging construction projects. Read about challenging design issues, fresh approaches on performance, future projects, and industry trends as well as ground movement and support, structure analysis, risk and cost management, rock tunnels, caverns and shafts, TBM technology and selection, and water and wastewater conveyance.

Historically, underground space has not had the allure of outer space, but how well we use the space beneath us may well determine our future. This compendium covers the past and present experiences in tunnels and tunneling, and explores the possibilities for the future.
