Development of an Implementation Manual for Geotechnical Asset Management for Transportation Agencies

In the past decade, considerable advancement has been made in Transportation Asset Management (TAM) to allow agencies to focus strategically on the long-term management of government-owned assets. In the past few years, the application of asset management principles to geotechnical assets has followed the general TAM development pattern and has been tried by a few state departments of transportation and other agencies. However the results to date are mixed, with considerable differences in approaches and results. Early efforts have often focused on inventory and condition surveys, without continuing along the full TAM spectrum. As a result, the benefits of asset management have not been fully realized for geotechnical assets. The federal surface transportation bills, i.e., Moving Ahead with Progress for the 21st Century (MAP-21), and Fixing America’s Surface Transportation (FAST) Act, specify risk- and performance-based asset management for bridges and pavements and encourage state transportation agencies to develop and implement transportation asset management strategies for all assets within the right-of-way. To move beyond the initial steps of Geotechnical Asset Management (GAM) and focus on incorporation of geotechnical assets into transportation asset management, there is an urgent need for the following: (1) Guidelines for managing geotechnical assets consistent with and to supplement the AASHTO Transportation Asset Management Guide – A Focus on Implementation (2011). The contents would describe procedures, forms, and electronic data collection and management tools for inventory and condition assessment of assets and elements at all plan levels to provide agencies with a baseline risk-based asset management approach, considering MAP-21, FAST Act, and AASHTO-supported performance measures. (2) Examples of successful and unsuccessful GAM strategies for incorporating GAM into TAM, performance management, or risk management programs; concepts for the measurement and tracking of economic, safety, mobility, and condition consequences from geotechnical asset performance; and life-cycle analysis tools. (3) Definition and taxonomy of geotechnical assets to support communication and comparability among state DOTs. (4) Performance-based goals, targets, and means of measurement for geotechnical assets. Measurements can be technical (such as specified movement) or they can be non-technical, for example a user perspective or a maintenance cost. (5) Ways to incorporate risk analysis principles and processes into asset management for geotechnical assets. Define risk and identify risk elements related to specific geotechnical assets. These should include typically understood consequences such as personal injury or loss of life and property damage, but also including such elements as economic consequences and impacts to environment, mobility and performance, and maintenance costs. The objective of this research is to produce a manual for developing and implementing a geotechnical asset management program. The manual will provide plans and tools for a consistent management program that is flexible enough to allow varying adaptations by different agencies as they integrate the geotechnical assets into their overall asset management program.
