Geotechnical Asset Management Plan: Analysis of Life-Cycle Cost and Risk

The Alaska Department of Transportation and Public Facilities is implementing a geotechnical asset management program for its rock and soil slopes, retaining walls, and material sites. The program includes a geographic inventory, periodic site assessment of condition and risk, and a quantitative investment analysis that includes risk and life-cycle cost. In developing the program, the department has addressed all the requirements of federal laws and the proposed regulations for performance measurement and transportation asset management (TAM) plans. Ultimately, the goal is to include these asset classes within the department’s TAM plan. This paper describes the motivation and goals of the analysis; performance assessment process; means of integrating risk with life-cycle cost; models of treatment cost, effectiveness, and deterioration; and methods for assessing the likelihood and consequences of service disruption. Examples focus on the inputs and results for rock slopes.
