Abstract
Transportation corridors are frequently located in complex geologic settings where unexpected geologic hazards may exist; either because of their rarity, or because they are beyond the previous experience of the engineers involved. This guidance was developed for the identification and characterization of geologic hazards affecting transportation corridors. It is designed to be efficient and easy to use, taking the form of flowcharts, checklists and concise documentation. The aim is to identify, characterize and evaluate geologic hazards in the early stages of engineering projects, in order to facilitate better selection of alignment alternatives, expedite the design process and prevent costly change orders during construction. The problematic effects of geologic hazards are not restricted to transportation corridors. Geologic hazards pose a threat to all kinds of engineered works, and are often a danger to human life. A system of hazard identification and characterization that could be implemented in the early stages of land-use planning and feasibility studies would be widely applicable and could potentially save money and lives. Previously, no single system has been developed to identify and characterize a wide range of geologic hazards. This document presents such a system.
