Description

TRB's National Cooperative Highway Research Program (NCHRP) Research Report 903: Geotechnical Asset Management for Transportation Agencies, Volume 2: Implementation Manual presents a manual that can be used to implement Geotechnical Asset Management (GAM) planning.

Volume 1, Research Overview, details the scope, process, and findings of the study.

The management of bridge and pavement assets has for many years garnered significant attention by state transportation agencies while the management of geotechnical assets—such as walls, slopes, embankments, and subgrades—has been elusive. Traditionally, geotechnical assets have been treated as unpredictable hazard sites with significant potential liability because failure of any geotechnical asset may lead to traveler delay, damage to other assets, or impact safety. Geotechnical assets are, however, vital to the successful operation of transportation systems and present an opportunity for system owners and operators to realize new economic benefits through risk-based asset management.

There are several downloadable files that accompany Volume 2. Links to those files and the information they contain include the following:

Appendices

Appendix A: Using the GAM Planner,

Appendix B: GAM Inventory Start Example,

Appendix C: GAM Model Formulation,

Appendix D: Geotechnical Asset Condition and Level-of-Risk Examples,

Appendix E: GAM Asset-Level Net Present Value Framework Worksheet,

Appendix F: GAM Plan Outline, and

Appendix G: GAM Implementation Barrier Mitigation Strategy Matrix.

Planner

This file contains the spreadsheet-based (Microsoft Excel) tool. User information for the GAM Planner is provided in Volume 2, Appendix A.

Template

This file contains a spreadsheet-based (Microsoft Excel) worksheet template for a life-cycle cost investment analysis tool. The template supports the process of selecting project-level treatment alternatives in GAM and can be used for investment-based treatment alternative analysis that considers asset or project life-cycle costs including design, O&M, and any potential rehabilitation or reconstruction treatments. User information for the NPV Template appears in Volume 2, Appendix E.

Training Slides

This file contains a slide-based presentation (created in Microsoft PowerPoint) that can be used during training for GAM.Downloadable files and the information contained in those

Note: To use the GAM Planner it is necessary to enable macros. Also, the “Excel Solver” must be installed. The Excel Solver is a plug-in provided with Microsoft Excel.
