This report is an updated version of the original engineering design guide published in 1995 by the Pipeline Research Committee (PRC) of the American Gas Association. As with the original document, it is intended to serve as a step-by-step guide for engineers engaged in the evaluation, design, and management of pipeline construction by horizontal directional drilling (HDD). Topics covered include a description of the HDD process, technical feasibility and cost considerations, surface and subsurface site investigations, drilled path design, steel pipe installation and operating stress analysis,...

As with the original document, it is intended to serve as a step-by-step guide for engineers engaged in the evaluation, design, and management of pipeline construction by horizontal directional drilling (HDD). Topics covered include a description of the HDD process, technical feasibility and cost considerations, surface and subsurface site investigations, drilled path design, steel pipe installation and operating stress analysis, environmental impact, construction contracts, and construction monitoring. The design guide includes two Microsoft Excel workbooks for use in analyzing HDD installation loads and stresses on steel pipe.
