The purpose of this manual is to provide field inspectors with the knowledge necessary to effectively monitor and document the construction of soil nail retaining walls. The manual provides information useful to both the experienced and inexperienced soil nail inspector. The manual is organized into two main parts: Preconstruction Preparation and Construction Inspection. Checklists are provided throughout the Construction Inspection sections of the manual which summarize key items discussed in the text. The inspector is encouraged to copy the checklists for use during construction. Appendix A contains blank forms that can be used for proper documentation and testing during soil nail wall construction. Appendix B contains examples of completed forms. Construction inspectors and engineers from California, Oregon, Texas, and Washington State departments of transportation contributed to this manual. The International Association of Foundation Drilling also provided input from the industry perspective.
