3 Introduction For a transportation infrastructure owner, geotechnical assets are the walls, slopes, embankments, and subgrades that contribute to the ability of an agency to perform its strategic mission. Legacy approaches often group geotechnical assets into the category of unpredictable liabilities or hazards.

4 Geotechnical Asset Management for Transportation Agencies, Volume 2: Implementation Manual How to Use the GAM Implementation Manual The GAM Implementation Manual introduces risk-based asset management concepts for geotechnical assets that can be used by departments of transportation (DOTs) and other transportation infrastructure owners at any stage of transportation asset management (TAM)

Overview 5 Part B is structured for learning GAM by doing GAM; it will enable the geo-professional or asset manager to begin implementing GAM regardless of agency stakeholder interest levels and without requiring mastery of complicated processes and data. As a process, GAM implementation as described in this manual proceeds using steps that have less precision than is typical in engineering design.

6 Geotechnical Asset Management for Transportation Agencies, Volume 2: Implementation Manual • A process to measure and manage involuntary safety risk exposure across the entire asset class; • Lessened traveler delay and closure times, resulting in improved network operational performance; • Reduced adverse economic impacts to users, private enterprise, and communities; • Fewer impacts and damages to other transportation assets; • Optimized resources, improved sustainability, and well-maintained reputation; • Enhancement of data-driven decisions that support agency and executive objectives; • A greater understanding of risk exposure levels and distribution, and the ability to manage those risks; and • The ability to start very simple and adapt the GAM process over time as the economic benefits are realized. The outputs from even a simple GAM plan will enable individuals responsible for geo technical assets to have a defensible basis for operational decisions, enhancing their ability to compete for resources and funds.
