In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase ineconomic incentives to the user. Because theoperating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to beshared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children'sbookofdefinitions wrote,"AHole...Is to Dig." But thisstatement is not necessarily true. Today, a hole could be to bore. Trenchless technology is not new. But it certainly has become the buzzword of the construction industry and it appears that it will have a growing impact in the way contractors, utilities, and others install new facilities. Methods to bore horizontal holes were practiced as early as the 18005, but this technology has greatly changed. Today's tools include sophisticated drilling methods, state-of the-art power systems, and electronic guidance techniques. These tools can bore faster, safer, and more accurately, and in many instances more economically, than open-cllt methods. Technology has played an important role in these advances, but economics has become the driving force in making these systems popular.

Pipeline Crossings (Manuals and Reports on Engineering Practice #89) was prepared by the Task Committee on Pipeline Crossings, Pipeline Crossings Technical Committee, Pipeline Division of the American Society of Civil Engineers. The purpose of this manual is to present common approaches for the design of crossing installations through the use of examples of standard practice as they exist in industry today. While the emphasis is on the pipeline crossing techniques of highways, railroads, and waterways, they can also be applied to cable and conduit crossings. The manual is divided into four major sections. First, general concepts are presented, including crossing environments, permits, and a description of the various types of crossings. The second section discusses the design issues while the different construction methods are explored in detail in the next section. Finally, the fourth section features a glossary of terms and a bibliography of resource materials. For new engineers, this manual may supplement what they were taught in school about pipeline design and construction. For more experienced engineers, it will hopefully provide useful options and guidelines from current practice.

This book includes recommendations prepared by members of the French Society for Trenchless Technology (FSTT), based on their recent national multi-year project. Comprehensive guidelines, techniques and theories in the areas of both microtunneling and horizontal drilling are given, encompassing the fields of application for each method, what investigations should be undertaken, which machines and equipment should be used, how the work should be managed and potential problems that may arise. The recommendations, the analytical methods used and their verification with laboratory and field data should not only improve the rate of success of trenchless projects, but will also be of great value to engineers in other countries, who can compare the results with their own findings and assess the international state of the art.
