This volume addresses the design of major pipeline or duct segments to be installed by horizontal directional drilling (HDD). This Manual of Practice, which covers topics specifically related to HDD installation, was prepared by a committee of senior engineers who are leaders in the development of HDD techniques and practices. HDD is a trenchless excavation method that is accomplished in three phases and uses a specialized horizontal drilling rig with ancillary tools and equipment. This Manual is meant to be a guide for design engineers with previous experience and knowledge of the HDD installation process and pipeline design methods. Topics covered include: predesign surveys; drilled path design; pipe design; construction impact; and as-built documentation.

MOP 108 addresses the design of major pipeline or duct segments to be installed by horizontal directional drilling (HDD).

This is a complete sourcebook of information on Horizontal Directional Drilling, the installation of pipelines and utilities beneath obstacles such as water and roadways. HDD is a fast-growing technology in the trenchless industry. Provides technical information on the design, permitting, construction, bid documents, specifications, and construction of HDD applications Numerous HDD calculations with examples

Trenchless technology allows for the installation or renewal of underground utility systems with minimum disruption of the surface. As water and wastewater systems age or must be redesigned in order to comply with environmental regulations, the demand for this technology has dramatically increased. This is a detailed reference covering construction details, design guidelines, environmental concerns, and the latest advances in equipment, methods, and materials. * Design and analysis procedures * Design equations * Risk assessment * Soil compatibility and more

Published by the Plastics Pipe Institute (PPI), the Handbook describes how polyethylene piping systems continue to provide utilities with a cost-effective solution to rehabilitate the underground infrastructure. The book will assist in designing and installing PE piping systems that can protect utilities and other end users from corrosion, earthquake damage and water loss due to leaky and corroded pipes and joints.

MOP 133 provides a detailed description of the pilot tube and guided boring methods with chapters on project planning, site and geotechnical assessment, shaft design, pipe characteristics and design, contract documents, and construction aspects.
