Utilization of a Geotechnical Asset Management Program – Lessons Learned from a Highway Improvement Project in Alaska

Over the past several years, efforts by owners, including State Departments of Transportation, have been initiated to develop asset management databases. One subset of an asset management database that can be challenging to define is that of geotechnical assets. Geotechnical assets include rock slopes, soil slopes, and retaining structures, that can have very long design lives and show few signs of distress for years. For a highway improvement project in Ketchikan, Alaska, the authors used the Geotechnical Asset Management Program (GAMP) provided by the Alaska Department of Transportation and Public Facilities (ADOT&PF) to review the locations and characteristics of unstable rock slopes, unstable soil slopes, and retaining walls along the project alignment. Reviewing this information allowed the authors to prioritize locations for inspection, rock mass and discontinuity surveys, and sample collection. As a result of the baseline geotechnical asset information collected, field efforts were reduced, resulting in cost savings to the ADOT&PF. In addition, using the baseline data, additional data were collected and key locations were identified where future maintenance and capital efforts should be focused. Utilization of the GAMP information for this project also provided ADOT&PF with information that can improve the quality of information collected on future GAMP efforts in Alaska
