Vision for Geotechnical Asset Management at Alberta Transportation
Kristen M. Tappenden, Roger K. Skirrow
In the proceedings of: GeoVirtual 2020: 73rd Canadian Geotechnical ConferenceABSTRACT: Geotechnical assets such as soil and rock slopes, retaining walls, embankments, and subgrades play a crucial role in the functioning of transportation networks. These same assets also pose potential threats to the transportation system as a result of deteriorating condition, escalating maintenance costs or catastrophic failures. Alberta Transportation is responsible for managing approximately 500 identified geohazard sites through the province. This paper will describe Alberta Transportation’s current Geohazard Risk Management Program (GRMP), and the vision for transforming this program into a formalized Geotechnical Asset Management (GAM) program. The goals of GAM at Alberta Transportation are to enhance the Department’s ability to monitor the condition and deterioration of the geotechnical asset inventory, forecast future funding requirements to achieve desired levels of service and risk reduction, and facilitate evidence-based decision making that considers the full life cycle costs and benefits of our geotechnical assets.
RÉSUMÉ: Les actifs géotechniques tels que le sol et les pentes rocheuses, les murs de soutènement, les remblais et les sous-couches jouent un rôle crucial dans le fonctionnement des réseaux de transport. Ces mêmes actifs constituent également des menaces potentielles pour le système de transport en raison de la détérioration de l'état, de l'escalade des coûts de maintenance ou de défaillances catastrophiques. Alberta Transportation est responsable de la gestion d'environ 500 sites géorisques identifiés dans la province. Ce document décrira le programme de gestion des risques géographiques (GRMP) d’Alberta Transportation et la vision de la transformation de ce programme en un programme officiel de gestion des actifs géotechniques (GAM). Les objectifs de GAM chez Alberta Transportation sont d'améliorer la capacité du Ministère de surveiller l'état et la détérioration de l'inventaire des actifs géotechniques, de prévoir les besoins de financement futurs pour atteindre les niveaux de service et la réduction des risques souhaités, et de faciliter la prise de décisions fondées sur des preuves qui tiennent compte de la pleine coûts et avantages du cycle de vie de nos actifs géotechniques.
