Authors Al-Bayati and Panzer discuss the use of utility location services and the role that all stakeholders contribute to the reduction of damages to underground utilities during construction.

Written by a field manager with 17 years experience, this is an in-depth training manual for employees of municipalities, utility companies, and contract locating firms. With over 300 photos and illustrations, this is the first book to provide an actual curriculum for locating buried utilities. Chapters include Laws & Regulations, Waves & Frequencies, the EM Locate Machine, Step by Step Locating, Common Terms, Telephone Cables, Fiber & Coaxial, Pressurized Water Pipes, Traffic Systems, Electrical Power, Natural Gas, Private Utilities, and much, much more. The basic physics of EM locating is explained in EM Wave Theory, Conduction, Induction, Phase, Capacitance, EMF, Ohm's Law, etc., while the chapter on Telephone Cables includes T-Screens, Lead Cables, Repeaters, Load Coils, Pair Gain, etc. From 3 phase primaries and cathodic protection to fiber jumpers and ATMS systems, this book covers it all, the historical, technical, and procedural knowledge needed to safely locate underground utilities.

For thousands of years, the underground has provided humans refuge, useful resources, physical support for surface structures, and a place for spiritual or artistic expression. More recently, many urban services have been placed underground. Over this time, humans have rarely considered how underground space can contribute to or be engineered to maximize its contribution to the sustainability of society. As human activities begin to change the planet and population struggle to maintain satisfactory standards of living, placing new infrastructure and related facilities underground may be the most successful way to encourage or support the redirection of urban development into sustainable patterns. Well maintained, resilient, and adequately performing underground infrastructure, therefore, becomes an essential part of sustainability, but much remains to be learned about improving the sustainability of underground infrastructure itself. At the request of the National Science Foundation (NSF), the National Research Council (NRC) conducted a study to consider sustainable underground development in the urban environment, to identify research needed to maximize opportunities for using underground space, and to enhance understanding among the public and technical communities of the role of underground engineering in urban sustainability. Underground Engineering for Sustainable Urban Development explains the findings of researchers and practitioners with expertise in geotechnical engineering, underground design and construction, trenchless technologies, risk assessment, visualization techniques for geotechnical applications, sustainable infrastructure development, life cycle assessment, infrastructure policy and planning, and fire prevention, safety and ventilation in the underground. This report is intended to inform a future research track and will be of interest to a broad audience including those in the private and public sectors engaged in urban and facility planning and design, underground construction, and safety and security.
