Reston, Va. — Horizontal Auger Boring Projects, Second Edition, is a comprehensive manual of practice covering horizontal auger boring techniques for pipeline crossing. The second edition of MOP 106 presents current practices for the planning, design, and construction of pipelines under highways and railroads using Horizontal Auger Boring (HAB). These cost effective and versatile techniques can also be applied to various utility installations crossing under or parallel to roads and streets.

Divided into seven sections, this manual starts with an overview of HAB and other trenchless alternatives. The second section provides details of the HAB system, including system components, recent innovations, and variations of the HAB system. The remaining five sections provide information on the planning phase, geotechnical investigation, design phase, and construction phase of a horizontal auger boring project.

Prepared by ASCE’s Horizontal Auger Boring Task Force, this manual of practice will assist engineers, contractors, and owners involved in new pipe installation projects using HAB methods to design and carry out projects effectively and safely.
